Abstract: A field experiment was conducted at the Ugar Sugar Factory premises, Ugar-Khurd, Belgaum district to study the effect of long-term spentwash irrigation on physical and biological properties in a Vertisol under Northern Dry Zone (Zone-III) of Karnataka. The long-term spentwash irrigation for >20 years reduced bulk density (1.43 to 1.22 Mg m-3), dispersion index (8.09 to 7.84) and erosion index (4.15 to 3.93) of the surface soil. The other physical properties like maximum water holding capacity (74.46 %), per cent water stable aggregates (66.16) and infiltration rate (0.79 cm hr-1) was higher in the treatment where spentwash was applied for >20 years. Application of spentwash increased the population of bacteria, actinomycetes and fungi in the soil over control. The highest bacterial population (10.21 cfu x106) was noticed in treatment that received spentwash for 5 to 10 years of surface soil. The highest fungi population (14.56 cfu x104) was recorded in the treatment that was irrigated with spentwash for > 20 years. In general, bacteria, fungi and actinomycetes population decreased with depth in all the treatments.

Abstract: Potato is the most abundantly produced edible food in the world, next to cereal. Potato is a wholesome food. Apart from starch of which it is a rich source, it provides essential body-building substances such as vitamins minerals and protein. Potato is one of the richest sources of calories needed to main day-to-day output of human energy. The present study was carried out in Tripura during 2013-14. A Sample of true potato seed farmers comprising 150 respondents was selected on stratified random sampling with proportional allocation method. The primary data was collected using pre-tested structured interview schedule. All of the farmers used treated seeds because tuber lets were already treated by dealers and farmers are also aware of the benefits of treated seed. Majority 50 per cent of the respondents had medium extent of adoption followed by high level of adoption 45 per cent and low 5 per cent level of extension. This indicates that majority of the farmers were in medium and high level of adoption due having good knowledge and aware of high production as compare to tradition potato seed cultivation practices. Correlation coefficients betweenFamily size, Education, Annual income, Operational land holding Cropping intensity Innovation-proneness Economic motivation Risk orientation, Contact with extension staff, Mass media exposure and Sources of information were found to be positive and significant of personal, psychological & communication characteristics with adoption of TPS cultivation technology of the farmers.

Abstract: Twelvehybrids along with their seven parents were subjected to study the genetic variability indicated that genetic material in the present investigation possessed variability which provides sufficient basis for selection by breeder.High estimates of PCV and GCV were obtained for biological yield per plant and seed yield per plant indicated a good deal of variability in those characters signifying the effectiveness of selection of desirable types for improvement. High heritability was observed for all the traits indicated that the characters under study are less influenced by environment in their expression. All the traits under study showed low genetic advance ranging from 1.68 to 2.05. High heritability coupled with high genetic advance as percentage of mean (GAM) were observed for straw yield per plant, seed yield per plant and 1000 seed weight, indicating predominance of additive gene action for these characters. Hence, simple selection based on phenotypic performance of these characters would be more effective.

Abstract: The present investigation was carried out in the segregating population of two rice cross combinations viz., Swarna x Ranbir basmati and Swarna x BR2655. The results revealed that the appreciable genetic variability for grain iron and zinc content along with other biometrical traits. Moderate to high variability was observed for grains per panicle, grain length, L/B ratio, in Cross 1 and Cross 2 for plant height, grains per panicle, in F3 generation. Hence, these traits need one or more generations in order to attain homozygosity. The existence of comparatively moderate variability for these traits, which could be exploited for improvement of the traits through selection in advanced generations. The high genotypic and phenotypic coefficient of variability were observed for panicle weight, grain yield kg per ha, in Cross 1(Swarna x Ranbir basmati) and Cross 2 (Swarna x BR2655) for number of panicles per plant, panicle weight, grain yield. It indicates high variability among the lines. High heritability coupled with high genetic advance as per cent of mean were recorded for plant height, number of panicle per plant, panicle weight, number of grains per panicle, L/B ratio, grain yield kg per ha in Cross 1(Swarna x Ranbir basmati) and Cross 2(Swarna x BR2655) for number of panicle per plant, panicle weight, number of grains per panicle, grain yield kg per ha. This indicates scope of selection in the population, since there is a wide range of variation and additive gene action.

Abstract: Okra yellow vein mosaic disease is caused by Okra yellow vein mosaic virus (genus Begomovirus and family Geminiviridae) of the most serious disease of okra. The only known method of transmission of OYVMV is through whitefly (Bemisia tabaci Genn.). The studies on the transmission of this disease by mechanical, graft and insect vectors were conducted during Kharif, 2012 and 2013 at net house and glass house of the Department of Plant Pathology of this University. Results have indicated that OYVMV was readily transmitted by whitefly (Bemisia tabaci) and graft inoculation. However, mechanical sap and aphids (Myzus persicae, Aphis gossypii and Aphis craccivora) could not transmit the virus.

Abstract: In the remote areas of the Indian Himalayan Region, the inhabitants largely depend on medicinal plants for curing diseases and income generation. But, proper documentation of the medicinal plants has been poorly attempted. The value of medicinal plants in traditional healthcare practices provides clues to latest areas of research in biodiversity conservation. Keeping this in view, the present study has been conducted to study the diversity, distribution and indigenous uses of medicinal plants in Kullu district of the Himachal Pradesh. A total 528 economically important plant species (Angiosperms: 477; Gymnosperms: 09 and Pteridophytes: 42) belonging to 103 families and 294 genera were recorded and used by the inhabitants of the area. Amongst 528 economically important species, 223 species were used as medicine, 85 species were found to be as wild edible/food, 175 species having fodder value, 49 species providing fuel, 11 species of timber importance, 44 species of religious significance, 20 of them being used for making agricultural implements whereas, 11 are being used as insecticide and 10 of them used as condiments in the study area. Maximum species (477 spp.) were reported in the altitudinal zone of 2100m-2800m above msl and species diversity decreased with increasing altitude in the study area. The continued over-exploitation, habitat degradation and changing environmental conditions may lead to the extinction of these species within a few years. Therefore, regular monitoring of population and habitats using standard ecological methods, development of conventional and in-vitropropagation protocols, establishment of species in in-situ and ex-situ conditions have been suggested.

Abstract: The experiment on sixty wheat (Triticum aestivum L) genotypes was carried out during 2013-14. Evaluation of eleven seed vigour traits viz, length of seed (mm), breadth of seed (mm), 1000-seed weight (g), seed germination (%), speed of germination (in lab), speed of germination (at field), field emergence (%), shoot length (cm), root length (cm), seedling length (cm) and vigour index. Highly significant differences were observed among the genotypes for all the seed vigour traits.The speed of germination (at field) showed the highest genotypic coefficient of variation followed by shoot length, vigour index and 1000-seed weight. A highest estimate of heritability and genetic advance was exerted by shoot length followed by vigour index, speed of germination-at field, 1000-seed weight, speed of germination-in lab, seedling length and root length. Heritability and genetic advance indicated that the additive nature of gene action and reliability of those characters for selection and emerged as ideal traits for improvement through selection.

Abstract: The present study was under taken to find out the genetic diversity of various maize genotypes for ten metric traits. Ten parental lines, three testers and their 30F1s were evaluated in a randomized block design in order to identify genetic divergence on the basis of non-hierarchical euclidean cluster analysis in maize (Zea mays L.). All the genotypes were grouped into seven clusters revealing the presence of considerable amount of genetic diversity in the material for different traits. According to results, cluster II, VI and VII each had the maximum nine genotypes. Cluster I and V had minimum genotypes withfive and two genotypes, respectively. The highest intra-cluster distance value was found for cluster III (127.613) followed by cluster VII (68.551) and lowest intra-cluster distance was found in cluster V (11.517). The maximum inter-cluster distance was recorded between cluster III and VI (1945.319) followed by cluster III and VII (1279.354) whereas, minimum inter-cluster distance was observed between clusters I and II (91.049). Based on results, genotypes grouped into different clusters showed more valuable heterotic pool that could be utilized in crossing the genotypes selected from those cluster which have maximum inter-cluster and intra-cluster distance in developing the desirable segregants.

Abstract: Radish, (Raphanus sativus L.) var. Punjab Safed was planted to study the insect pollinator’s diversity, abundance and their pollination efficiency, at the Vegetable Sciences Research Farm, CCS Haryana Agricultural University, Hisar, India. Observations of most frequent pollinators were taken throughout the blooming period of the crop during March 2011. The hymenopterans were the major floral visitors, comprising of ten species from three families viz., Apidae, Vespidae and Scoliidae, followed by dipterans (three species from one family) viz., Syrphidae, lepidopterans (five species from four families) viz., Pieridae, Nymphalidae, Papilionidae and Arctiidae. Among these, A. florea, A. mellifera, A. dorsata and A. cerana were found to be the most frequent visitors. The abundance of A. mellifera was highest (6.8 bees/m2/5 minutes) followed by A. florea (5.1 bees/m2/5 minutes), A. dorsata (3.5 bees/m2/5 minutes) and A. cerana (1.4 bees/m2/5 minutes). Irrespective of species, the bee population was highest at 1100-1300 h of the day. A. cerana and A. florea had highest and lowest foraging rate 10.3 and 8.9 flowers/minute, irrespective of day hours, whereas (irrespective of species) foraging rate during 0900-1100h was observed highest 14.5 flowers/minute. A. cerana had highest foraging speed 7.5 seconds/flower and A. mellifera (8.4 seconds/flower) had least, irrespective of day hours whereas (irrespective of species) foraging speed during 1500-1700h was observed highest 14.8 seconds spent per flower. Based on pollination index (Number of loose pollen grains sticking on the body of bee x abundance), A. mellifera was found to be the most efficient pollinator of radish flowers followed by A. dorsata A. florea and A. cerana under agro-ecological conditions of Hisar, (India).

Abstract: Nutrient management and planting density have become an important consideration in kinnow management. Kinnow planting and nutrition should zbe planned so that biological and management aspects are interrelated to maximize economic returns. Keeping this in view, the study was initiated to find out the appropriate spacing and nutrition level for Kinnow in arid irrigated region of Bathinda. The effect of tree spacing and nutrition on vegetative performance and yield of 6 years old kinnow mandarins raised on rough lemon rootstocks were studied at Regional Research Station, Bathinda during the year 2012-13. Plants were grown at three different spacing viz. S1 (6x6m), S2 (6x5m) and S3 (6x4m) and given three different levels of nutrition viz. L1 (75% inorganic + 25% FYM), L2 (50% inorganic + 50% green manure) and L3 (100% inorganic only). Maximum plant height was observed under spacing S3 (3.24 m) and nutrient level L1 (3.21 m), however, maximum spread (E-W) was noted under S2 and L2 and spread (N-S) under S1 and L3. Maximum number of fruits per plant (161.66) was counted in L3 and S2 (155), whereas maximum average fruit weight was weighed in L2 (150.80 g) and S1 (145.19). Maximum fruit yield (22.26 Kg/plant) was observed in L3 and S2 (22.40 Kg/plant). Fruit quality in terms of juice and TSS was not affected by any of the spacing and nutrient levels. However, maximum acidity was recorded in L3.

Abstract: In order to rejuvenate the senile guava orchard, 20 year old guava cv. ‘Allahabad Safeda’ trees were headed back at the height of 1.5 m, 2.0 m and 2.5 m from ground level keeping the senile trees as a control in the month of March. These headed back trees were again subjected to pruning intensity of 0 %, 25 %, 50 % and 75 % of total length of these newly emerged shoots after 5 months of heading back. The un-pruned headed back trees were treated as control. The observations revealed that there was significant improvement of number of fruits and fruit yield per tree with the age of heading back of senile trees. Although, the mean number of fruits per tree was lesser in headed back tree than senile tree during the period of 2010 to 2014, but, among headed back trees highest mean number of fruits per tree was recorded in plants headed back at 1.5 m. Similarly, fruit weight and yield per tree was also significantly higher in headed back trees than senile trees. Among headed back trees maximum average fruit weight and fruit yield was observed in 1.5 m headed back trees. Intensity of pruning also influenced the fruit yield and quality. The headed back trees pruned at 50 per cent level performed comparatively better than other pruning levels. Fruiting density was almost 2.5, 1.8 and 1.5 times higher in trees headed back at 1.5 m, 2.0 m and 2.5 m, respectively than senile trees. Total soluble solids and acidity of fruits was also improved with heading back of senile guava trees.

Abstract: Tannase or tannin-acyl-hydrolase (E.C.3.1.1.2.0) catalyzes the hydrolysis of ester and depside bonds in hydrolysable tannins, as tannic acid, releasing glucose and gallic acid. The present work explored the production, optimization of various parameters like pH, temperature, incubation period, salt-concentration, carbon sources & nitrogen sources and growth profile of tannase by Bacillus cereus. Tannase from the bacterium showed optimal activity at 48 h and 35°C with 1M salt concentration and initial pH 4.5. The peak enzyme activity was observed while supplementing sucrose at 1% conc. and maltose at 1 % & 2 % conc. as carbon sources, ammonium chloride at 3% concentration as nitrogen source. The maximum tannase activity 0.1586 U/ml was recorded in the mid-exponential phase of Bacillus cereus. Bacillus cereus thus has high potential and may be useful for industrial production of tannase.

Abstract: Field investigation was carried out to find out the effect of number of cuttings on seed yield and quality parameters of multicut fodder sorghum cv. CoFS-29 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during 2012-13. The experiment was laid out in the Randomized Complete Block Design with four replications, comprising of five cutting management practices viz., uncut (control) crop, one cut crop, two cuts crop, three cuts crop and four cuts crop. The results showed that with increasing frequency of cuttings from zero to four cuttings, the seed yield and quality parameters have been reduced drastically. Among the five cuttings, the uncut crophas produced significantly the maximum number of productive tillers per plant (9.95), panicle length (42.48 cm), dry fodder yield per hectare at harvest (88.89 q ha-1), seed yield per hectare (576.4 kg), 1000 seed weight (6.08 g), seed germination (70.00), seedling length (28.15 cm), seedling vigour index (1971) and seedling dry weight (47 mg seedlings-10) and the least EC value (0.225 dSm-1) followed by the one and two cuts crops. On the contrary, all these seed yield attributing and quality parameters were minimum in the four cuts crop.Thus, it is concluded that cutting of the crop at vegetative stage for fodder purpose is not advisable for seed production of multicut fodder sorghum since the uncut (no cutting) crop has recorded significantly higher seed yield and quality attributing components as against the four cuts crop. The next higher seed and fodder yields with comparable quality parameters could be obtained from the one cut crop.

Abstract: The present investigated was conducted to investigate the potential effect of biofertilizers (mycorrhiza and PSB) and different levels of phosphorus (0, 10, 15 and 20 g/m2) on growth, yield and quality of chrysanthemum. The interaction effect of phosphorous levels and biofertilizers on plant spread was found to be significant in first year, while it was non-significant in second year. In first year (2011-12), the maximum plant spread (19.12 cm) was recorded with the application of PSB in combination of phosphorus 15 g/m2. The interaction effect of phosphorous levels and biofertilizers on number of branches/plant, number of days taken for first flowering, number of days taken for 50% flowering and fresh weight of flower were found to be non-significant in both the years of investigation. The interaction effect of phosphorous levels and biofertilizers on duration of flowering was found to be significant in first year, whereas, it was non-significant in second year. The longest flowering duration (45.67 days) was obtained with PSB in combination of phosphorus 15 g/m2 in first year. The interaction effects of phosphorous levels and biofertilizers on flower size was observed significant in first year, whereas, it was non-significant in second year. In first year (2011-12), the biggest flower (4.50 cm) was obtained with PSB + phosphorus 20 g/m2, which remained at par with PSB + phosphorus 15 g/m2 (4.41 cm). The maximum flower yield per plant (61.96 and 61.31 g) was recorded with PSB application along with phosphorus 15 g/m2, however, in first year, it was at par with mycorrhiza along with phosphorus 15 g/m2 (57.92 g).

Abstract: Rainfall and temperature are two important parameters among the climate change variables which can affect agricultural production through their direct as well as indirect effect. An important link between climate change and agricultural productivity is an essential pre-requisite to generate variable predictions about impact of climate change and variability. In this study, MarkSim DSSAT weather file generator was used to predict the rainfall and temperature data on daily basis for SRES emission scenarios (A1B, A2 and B1) under the ECHam5 model for 80 years (2011-2090). The mean decadal rainfall decreases is decreasing in trend (approximately 13.2 percent)from 2011 to 2090 showing higher reduction from mid to end of 21st century. The mean decadal annual rainfall is likely to be maximum during 2011-20 (774.8 mm) followed by 2021-30 (767.3 mm) and minimum during 2081-90 (672.4 mm) being statistically similar among the three scenarios and different among the decades. The decadal maximum temperature is likely to rise by 18.6, 9.3, 10.4 and 13.0 percent under the four respective quarters of the year with an average rise of 12.8 percent. However, the decadal minimum temperature is expected to rise by 50.9, 15.2, 15.7 and 34.6 percent under the four respective quarters of the year with an average rise of 29.1 percent. The rise of temperature is likely to be greater in case of minimum temperature especially in first and fourth quarters respectively.

Abstract: A total of 30 sheep received for necropsy over a period of 6 months were thoroughly examined. Seventy two tissue samples were collected from 30 sheep showing the gross pathological lesions of gastrointestinal tract disorders. Out of which, 48 confirmed isolation of E. coli based on culture characteristics and biochemical tests and 14 sheep were found E. coli positive. Infection was prominent in less than one year age groups and more in male sheep. Out of 48, only 18 strains were sent for serotyping. Out of which, 13 belonged to ‘O’ serogroup, whereas remaining five isolates were untypable strains. The most prevalent serotype was O168(5) followed by O60(4), O1(1), O91(1), O102(1) and O116(1). In- vitro drug sensitivity pattern by the single disc diffusion method revealed maximum sensitivity to polymixin B, ofloxacin, amikacin, ampicillin, colistin, furoxone, amoxycillin+clavulanic acid, cefixime, amoxicillin, amoxycillin+sulbactum, doxycycline, ciprofloxacin, cefpodoxime, co-trimoxazole and nalidixic acid in decreasing order.

Abstract:Twenty CGMS-based pigeonpea [Cajanus cajan(L.) Millspaugh] hybrids were synthesized manually by crossing five CMS lines (A lines) with 11 male lines (R lines) and these hybrids wereevaluated to studyyield potential with the performance of their R- lines. The results showed that the restoring capacities of restorer linesare very important to quality seed production and for yield potential.Result from the study indicated thatmost of the R- line acts as good restorer and it ranged from98.50% (ICPL 20108) to 59.22%(ICPL 2009.In present study most of the hybrids showed standard heterosis towards in desirable direction for yield and yield contributing characters over the checks so these cross combination of parent may be exploited to developed the hybrid in pigeonpea for obtaining higher grain yield.The range of standard heterosis over Asha for grain yield per plant was ranged from -13.06 (ICPA 2092 x ICPL 20123) to 40.91% (ICPA 2047 x ICPL 20126).

Abstract: The study was undertaken to study the influence of micronutrients (Zn and B), bio-fertilizers (Azotobacter and PSB) and pesticide (Imidacloprid) in sunflower. The experiment consists of fifteen treatments laid out in Randomised Complete Block Design with three replications. Treatments include application of micronutrients through different methods like seed treatment, soil application and foliar application in combination with bio-fertilizers and pesticide as individual applications and in combinations along with RDF (90:90:60 kg NPK ha-1). The experimental results revealed that, seed treatment with micronutrients, bio-fertilizers and pesticide interacted positively in combined application compared to individual application. Different growth indices like LAD, AGR, CGR, RGR and NAR are significantly influenced by these methods at varied rate. Seed treatment with ZnSO4, borax and bio-fertilizers triggered the early plant growth. Hence recorded higher seed yield (2186 kg ha-1) compared to RDF alone (1895 kg ha-1). Seed treatment acts as feasible alternate tool for farmers to improve the early growth of sunflower (KBSH-53) crop and seed yield.

Abstract: Papaya (Carica papaya L.) is a delicious fruit widely cultivated in tropical and subtropical areas.India is first among papaya producing countries in the world producing around 5.2 million tons of papaya during 2012-2013. Papaya fruits are highly perishable in nature and postharvest losses of up to 75% have been reported to Hawaii shippers by mainland USA wholesalers and retailers.The present investigation was under taken at the Department of Processing Technology, College of Agriculture, Vellayani, during 2012-2014, with the objective to standardize postharvest practices for improved shelf life.The fruits harvested at ¼ maturity stage and were sanitized with hot water at 50° C for 20 minutes and warm sodium hypochlorite 150 ppm for 10 minutes. The fruits were sanitized and waxed and kept in corrugated fibre board boxes with ethylene absorbent potassium permanganate and kept under ambient temperature were studied. Fruits treated with hot water at 50° C for 20 minutes with waxing and with ethylene absorbent recorded highest shelf life of 11 days. Potassium permanganate reduces the autocatalytic process of ethylene during ripening and hence delayed the ripening process. In the present experiment all the treatments with waxing resulted in less mechanical damage suggests that waxing might have resulted in reducing the severity of bruises in the skin during transport.

Abstract: Figs (Ficus) and fig-pollinator-wasps (Agaonidae) are highly coevolved mutualists that depend completely on each other for continued reproduction. In this study these pollination phases of monoecious species- F. racemosa was studied in three different seasons’ viz., winter, summer and rainy. Alongside this, the efficiency of pollination was also studied. In general, mean syconia size is high in summer season followed by rainy and winter season. t-test indicated that while the syconia sizes differ significantly between rainy and winter.In rainy and summer seasons foundress wasps started entering in to syconia after 8 and 12 days respectively; it stabilized on 16th day in summer season and on 20th day after synconial development in rainy season. Number of foundress wasps was higher in general in summer (8.22) followed by rainy (4.17) and winter 2.89; these differences were also evident in the frequency distribution of number of foundress wasps in three seasons. Accordingly the four stages viz., A, B, C and D also differed among seasons. Differences among seasons were more pronounced. Pollination efficiency as evident by the number of wasps entering the syconia, was higher in summer followed by rainy and winter season. Similarly the pollination efficiency measured as the number of wasps and seeds emerging, also showed a similar trend- summer being the best and least efficient during winter.

Key words.: Fig, Pollination, foundress wasp, Season

Abstract: The experiment was carried out in the field of the Department of Horticulture, Janta College, Bakewar, Etawah (U.P.) during Rabi season of the year 2013-14. The layout of experimental field was laid down in Randomized Block Design with 9 treatments. These treatments randomized in three replications with total number of 27 plots. The observations were recorded for yield attributing characters of radish. Observations gathered with respect to increased over the length of roots (34.12 cm), diameter of root (3.43 cm), fresh weight of root (193.03 g), yield per plot of radish (5.06 kg) and root yield of radish (843.43 q/ha) was obtained with the treatment T8- NPK + FYM + PSB (80:60:60 kg/ha) + (10t/ha) + (5kg/ha). Statistical analysis revealed that treatment T9- NPK + FYM + Azotobacter +PSB (80:60:60 kg/ha) + (10t/ha) + (5kg/ha) + (5kg/ha) have increases the leaf: root length ratio (1.76) and treatment T6- NPK + FYM (80:60:60 kg/ha + 10t/ha) have increases the leaf: root weight ratio (1.86) which is significantly higher over the rest of treatments. However, minimum values were obtained to control.
