Abstract: The study was carried out during autumn season of 2003-04 and 2004-05.The soil of experimental site was sandy loam, having pH 8.5, organic carbon 0.45%, total nitrogen 0.04%, available phosphorus 10kg ha-1 and available potassium 278kg ha-1, therefore, the fertility status was poor. The treatment comprised of control, RDF, 50% RDF+100kg BOM ha-1, 75% RDF + 100kg BOM ha-1, 100% RDF + 100kg BOM ha-1, 50% RDF + 150kg BOM ha-1, 75% RDF + 150kg BOM ha-1, 100% RDF + 150kg BOM ha-1, 50% RDF + 200kg BOM ha-1, 75% RDF + 200kg BOM ha-1 and 100% RDF + 200kg BOM ha-1. These treatments were applied to dwarf field pea and Indian mustard under companion cropping of dwarf field pea and Indian mustard. The sowing of dwarf field pea and Indian mustard was done in north-south direction with row ratio of 5:1. Application of 100% RDF in the integration of 100kg BOM ha-1 (T5) and 75% RDF + 200kg BOM ha-1 (T10) increased the grain yield of dwarf field pea (2258 kg ha-1 in T5 and 2283 kg ha-1 in T10) and Indian mustard (264 kg ha-1 in T5 and 265 kg ha-1 in T10) over control (1013 kg ha-1 dwarf field pea and 102 kg ha-1 indian mustard) and recommended dose of fertilizer (1727 kg ha-1 dwarf field pea and 200 kg ha-1 Indian mustard). the nutrients supplied through 100% RDF + 100kg BOM ha-1 and 75% RDF + 200kg BOM ha-1 maintained the balance nutrition for dwarf field pea and Indian mustard in companion cropping system, which culminated to grain production of both crops. The growth and yield traits of both the crops were concordant to yields obtained from dwarf field pea and Indian mustard in companion cropping system.

Abstract: Front line demonstrations are the best powerful tool of extension to motivate the farmer for adoption of an innovation. Forty FLDs were conducted by the KVK dewas during kharif season from 2010-11 to 2012-13. All these demonstrations were carried out by the active participation of farmer’s with the objective to demonstrate the improved technologies of oilseed production potential. The improved technologies consist, use of high yielding short duration variety JS 95-60, proper seed rate, seed inoculation with rhizobium and PSB culture, integrated nutrient management and integrated plant management. Demonstrations recorded higher yield over farmer’s practice. The improved technology gave higher yield of 1938 kg/ha as compared to 1584 kg/ha in the farmer’s practice. In spite of increase in yield of soybean, technology gap, extension gap and technology index existed. The improved technology gave higher gross return, net return with high benefit cost ratio (2.21) as farmer’s practice (1.94). An average additional investment of Rs 2053/- per ha coupled with scientific monitoring of front line demonstration and non monitoring factors were resulted in additional return of Rs 12101/- per ha.

Abstract: An experiment was conducted to find out the optimum spacing and growth regulators levels in radish Cv. Pusa Chetki during 2014-15. The experiment consists of two spacing levels (45 × 45 cm and 30 × 30 cm) and five levels of growth regulators (GA3 200 ppm, GA3 250 ppm, NAA 200 ppm, NAA 250 ppm and control) in all possible combinations were assessed for vegetative and root parameters. Among the different spacings, S2 (45 x 45 cm) and among the different growth regulators levels, G2 (GA3 250 ppm) recorded maximum plant height, spread of plant, chlorophyll content in leaves, root length, root girth, fresh weight of root and dry weight of root. While, lower morphological and root parameters were observed at closer spacing S2 (30 x 30 cm) and in control G5 (water spray). Closer spacing recorded higher yield (23.52 t/ ha) compared to higher spacing (20.57 t/ha). Interactions of spacing and growth regulators levels were found significant with respect to morphological and root parameters. S2G2 (45 × 45 cm + GA3 250 ppm) treatment combination recorded significantly higher values for growth and root parameters.

Abstract: Among 46 chilli genotypes, the thrips reaction indicated that 7 genotypes of chilli showed moderately resistance to thrips, while 37 genotypes showed susceptible and 2 genotypes resulted highly susceptible for the thrips infestation. Thrips incidence was found negative and significant correlation with fruit yield (-0.233), number of fruits/plant (-0.325), number of primary branches/plant (-0.314). To understand the biochemical basis for host plant resistance, various biochemical constituents were analysed and correlated with the thrips incidence. The biochemical components like non reducing sugars (-0.283) and total chlorophyll (-0.310) showed negative and significant association with the thrips incidence but reducing sugars (0.332), calcium (0.358) and sulphur (0.266) resulted positive and significant correlation with the thrips infestation. Hence, the plant morphology and biochemical parameters need to be considered for early identification of resistant genotypes during population screening.

Abstract: The dissipation of imidacloprid insecticide was evaluated in okra crop at two application rates (20 and 40g a.i./ha) under field conditions of subtropical region. The extraction of imidacloprid was done by QuEChERs (Quick, Easy, Cheap, Efficient and Rugged) method and quantification by high performance liquid chromatography (HPLC). Dissipation of imidacloprid followed first order kinetics at both the application rates and the half-life (t1/2) for degradation of imidacloprid in okra was found to be 0.31 and 0.596 days at 20 and 40g a.i./ha treatment doses respectively. However no residues of imidacloprid (<0.02µg/g) could be detected at harvest time (15d after application of insecticide) either in okra or okra cropped soil.

Abstract: A field experiment was conducted during 2013-14 Rabi season. In present study twenty eight landraces of muskmelon collected from different parts of Karnataka along with two check varieties (Kashi Madhu and Durgapur Madhu) were characterized using PPVFRA DUS guidelines. The experiment was laidout in the Augmented Block Design, only check varieties were replicated in each of the four blocks once and the nine accessions of melon local types were randomly allotted for each blocks. Significant genetic variability was observed for most of the traits. The local melons exhibited wide variability for growth parameters and yield attributing traits. Growth performance results showed that the highest leaf blade length was recorded in COHB-006 (7.90cm) followed by COHB-001 (7.75cm) and highest leaf blade width was recorded in COHB-038 (10.20cm) followed by COHB-019 (10.00cm). Significant difference with respect to petiole length was also observed and COHB-019 recorded maximum petiole length (7.50 cm) followed by COHB-001 (6.50cm). Highest ovary length and width was recorded in COHB-002, COHB-032, COHB-034, COHB-037 (1.5cm) and COHB-012 (1.6cm) respectively. Based on the observations recorded, 23 genotypes were having monoecious sex form and seven genotypes were having andromonoecious sex form including both checks, Durgapur Madhu and Kashi Madhu. There was also significant difference with respect to yield attributing characters in all genotypes; highest fruit weight was recorded in COHB-034 (2.8kg). Genotype COHB-002 (25.00cm) produced longest fruits than the other genotypes. The highest flesh thickness was recorded in COHB-002 (4.38 cm). This study gives primary information regarding the genetic diversity existing among local muskmelon lines of Karnataka that could be utilized in crop improvement programme as well as conservation of germplasm.

Abstract: The present investigation consist of twenty genotypes of pigeonpea including check WRP-1which were studied in six different environments. The trials were conducted in a randomized block design with two replications in six different environment viz., kharif-2012, 2013 and 2014, three seasons of irrigated and same three seasons of rainfed condition. Highly significant differences among genotypes were observed for all the characters. Environmental + (Genotype x Environment) interaction was significant for all the characters except days to maturity, pod bearing length and 100 seed weight. All the traits under the study except for days to maturity and 100 seed weight showed significant differences in different environments. The variance due to pooled deviation was highly significant for all the characters except for primary branches and number of seeds per pod which reflect the presence of sufficient genetic variability in the material. The genotypes RVK-275 (X=41.2, bi=1.89 and S2di = 22.03), AKT-9913 (X =41.994, bi=1.70 and S2di = 18.25), ICP-8840 (X=37.9, bi=1.70 and S2di = 23.09) and RVK-285 (X=39.80, bi=1.50 and S2di = 29.56) were found to be a stable for seed yield per plant, test weight, primary branches, secondary branches, pod bearing length, number of seeds per pod and pod length, across the environments with good stability under rainfed and irrigated conditions compared to local check of the year 2012, 2013 and 2014. Path analysis revealed that days to 50% flowering (7.11), pod length (4.11), pod bearing length (4.32) and secondary branches(3.81) at genotypic level similarlynumber of pods per plant (0.70), 100 seed weight (0.42), days to maturity (0.32) and pod bearing length (0.32) at phenotypic level had the highest positive direct effect on grain yield. For maximizing the grain yield per plant emphasis should be given in selection of such characters for further improvement in pigeonpea. Two years of field screening for Fusarium wilt (FW) and Sterility Mosaic Disease (SMD), the genotype JSA-59 and WRP-1 is resistance to Fusarium wilt.JSA-59 and BDN-711 is resistance to SMD. Hence, it can be used directly as a variety or choice of parent for hybridisation programme.

Abstract:An investigation was undertaken with twin objectives of assessing the variability for grain nutrients among 561 maize inbred lines using NIR facility and to assess the grain yield potential of 53 selected protein rich maize inbred lines during summer and kharif-2014, respectively, following randomized block design with two replications. High genotypic co-efficient of variation for most of the characters indicated the presence of higher magnitude of genetic variability among the inbred lines. A close correspondence between phenotypic co-efficient of variation and genotypic co-efficient of variation for most of the characters indicated lower environmental influence and effectiveness of selection. Weak association between grain yield with crude protein and essential amino acids suggested their independent genetic control. The inbred lines grouped under different clusters differed significantly for most of yield related traits. The high yielding and high crude protein content inbred lines could be used as parents to develop high yielding-protein rich single cross hybrids.

Abstract:Twenty seven wheat genotypes were evaluated in Randomized block design for the study of correlation and path coefficient among the yield and yield contributing traits. Correlation study at phenotypic and genotypic level showed that grain yield per plant exhibit positive significant association with harvest index, test weight, biological yield, spike length, tillers per plant and plant height. In addition to above characters, flag leaf length and grain filling period also showed positive significant association with grain yield per plant. These characters are strongly associated with seed yield in wheat. Significantly inter correlation among traits is useful for breeding programme to improvement of yield and its components. Path analysis identified biological yield, harvest index, days to heading, spike length, grain filling period, plant height and test weight as highly desirable components for direct effects on grain yield. The inter-relationship among the characters identified above may be used in the breeding programme to exploit the yield potential for enhancing the productivity of the wheat and to develop high yielding varieties with ease and target oriented research work.

Abstract: The present investigation was carried out using 191 minicore collection of pigeonpea with 5 check varieties during kharif-2012 and kharif-2013 at two locations viz., Agricultural Research Station, Kalaburagi and Bidar. Analysis of variance revealed the significant difference among genotypes for all the characters. Genetic variability studies revealed high phenotypic co-efficient of variability (PCV), genotypic co-efficient of variability (GCV), heritability and per cent genetic advance for number of branches per plant, pod bearing length, number of pods per plant and seed yield per plant. Suggesting ample scope for improvement of yield through selection owing predominance of additive gene action for these traits. The characters like number of pods per plant and 100 seed weight had significant positive correlation with yield and high rate of positive direct effects with yield were observed both at phenotypic and genotypic level. It indicates that, emphasis can be laid on these two characters during selection of genotypes for improvement of yield. From two years of field screening for Fusarium wilt (FW) yielded eleven resistant genotypes of which ICP-8949, GRG-2009, ICP-11320, GRG-811 and GRG-333were wilt resistant and high yielding. The genotypes viz., Bahar, ICP-7035, ICP-11910 and RAJA were found resistant for Sterility mosaic disease (SMD). Hence, these genotypes can be used directly as a variety or choice of parent for hybridisation programme.

Abstract: Aquatic macrophytes have been widely studied because of their capability of absorbing contaminants from water and their subsequent use in biomonitoring. Free floating aquatic macrophyte Eichhornia crassipes were treated with various concentrations of treated tannery effluent, under repeated exposure in controlled laboratory conditions in order to assess their maximum bioaccumulation potential. Phytoremediation with E. crassipes for 9 days improved the physico-chemical properties of the 100% effluent. The reduction in pH, TS, BOD and COD were 9.52%, 38.90%, 41.42 and 38.27% respectively. Metal content in the effluent was remained 1.38 mg l-1 after treatment with E. crassipes. The result showed a concentration and duration dependent accumulation of Cr in plant tissues. However maximum bioconcentration of Cr was in roots of E. crassipes (324 µg g-1 fw), followed by leaves (112 µg g-1 fw) in 100% effluent after 9 days of exposure. Physiological and biochemical responses of the plant viz. total chlorophyll, protein content and NR activity decreased with increase in effluent concentration and duration. At highest concentration and duration a maximum reduction of 32.34% in total chlorophyll content, 42.47% in protein content and 46.66% in NR activity was found in E. crassipes. Thus in lieu of above mentioned study E. crassipes may be usedas bioindicator tool for evaluatingquality of water polluting Ganga river.

Abstract: The genetic variability, heritability and genetic advance over mean were estimated for yield and quality traits in sixteen ginger germplasms. Wide genetic variation was observed for all genotypes for plant height, number of leaves per plant and fresh yield per plant and. Considering genetic parameters, high GCV was found highest for number of leaves (28.64%) followed by oleoresin content (20.64%) and fresh yield per plant (18.12%), respectively. In all cases, phenotypic variances were higher than the genotypic variances. Based on high heritability (h2 b.s.) fresh yield per plant (89.20%), oleoresin content (80.30%), stem girth (79.39%), number of leaves per plant (75.69%) and plant height (67.93) were found superior and high GAM was observed for number of leaves (51.32%), oleoresin content (38.11%) and fresh yield per plant (35.26%) found superior traits and representing additive genetic variance. Effective selection would be made considering these traits.

Abstract: Botanical pesticides are based on plant extracts. Botanical insecticides have long been touted as attractive alternatives to synthetic chemical insecticides for pest management because botanicals reputedly pose little threat to the environment or to human health. The practice of using plant materials against field and storage pests however has a long history in many indigenous and traditional farming communities across the world. A number of plant substances have been considered for use as insect antifeedants or repellents, but apart from some natural mosquito repellents, little commercial success has ensued for plant substances that modify arthropod behavior. In conventional agriculture, botanicals face tremendous competition from the newest generation of “reduced risk” synthetic insecticides such as the neonicotinoids. In the context of agricultural pest management, botanical insecticides are best suited for use in organic food production in industrialized countries but can play a much greater role in the production and postharvest protection of food in developing countries.

Abstract: Leaf blotch disease usually appears on lower leaves in winter season starting period. This disease caused by Taphrina maculans (Butler and Bisby) and appears as small, oval, rectangular or irregular brown spots on either side of the leaves which soon become dirty yellow or dark brown. The leaves turn chlorosis to necrosis. The disease is characterized by the appearance of several spots on both the surfaces of leaves. The fungus is mainly air borne and primary infection occurs on lower leaves with the inoculum surviving in dried leaves of host, left over in the field. The ascospores discharged from successively maturing asci infect fresh leaves without dormancy, thus causing secondary infection. Secondary infection is most dangerous than primary one causing profuse sprouting all over the leaves. The integrated approach taken in field demo trials includes selection of seed material from disease free areas, treating the seed material with Mancozeb @ 3g/litre of water for 30 minutes and shade dry before sowing. Spraying of mancozeb @ 2.5 g/litre of water or Hexaconzole @ 1ml/litre; two sprays at fortnightly intervals and at heavy mist-fog season spraying of Copper oxy chloride 3 g/litre effective against leaf blotch disease.During the month of August to October more rain fall disease severity is high.

Abstract: Temperature stress during the reproductive phase in chickpea is generally allied with lack of pollination, abscission of flower buds, flowers and pods with substantial yield loss. Hot (>30oC) and dry atmospheric conditions lead to profligate loss of flower buds and open flowers in chickpea. A field experiment was conducted during rabi, 2014-15 at Dharwad, Karnataka with three genotypes (Annigeri-1, JG-11 and JG-14) as influenced by five sowing dates (D). The investigation revealed that the genotype, JG-14 under D1 temperature regime recorded significantly minimum pollen sterility per cent (5.18), whereas Annigeri-1 and JG-11 recorded significantly maximum pollen sterility per cent under D4 temperature regime (43.97 and 42.75). Similarly, Annigeri-1 and JG-11 showed significant positive correlation with Tmin and Trange under D1, D2 and D3 temperature regime. Likewise, JG-11 recorded significant positive correlation with Tmax under D4 and D5 temperature regime. Eventually JG-14, maintained least pollen sterility per cent under D1 temperature regime and averagely least under late sown and high temperature conditions than Annigeri-1 and JG-11. Apparently D1 temperature regime experienced least pollen sterility per cent and proved to be best sown condition for maximum pollen viability than lateral temperature regimes.

Abstract: Nursing the profession of caring for the sick and the convalescent, the disabled and helpless, is one of the noblest profession throughout the world. Nursing coversrange of function in their hospital and they are required to work at any point in the 24 hr day. Therefore, stress in the nursing profession is an ongoing worldwide problem. The present study was carried out to assess the physiological and psychological assessment of work. The descriptive data was collected with the help of interview schedule. The experimental data was gathered into different section such as physiological parameters (EE, HR and TCCW), postural discomfort scale (Nordic scale and REBA sheet) and psychological parameters (VAS, FSS). Total 120 nurses were selected through simple random sampling method in the 4 district uttarakhand. The result revealed that nurses were suffered from upper back pain (66.67%) and lower back pain (64.17%) due to awkward posture and inappropriate work station. In postural analysis through REBA, patient handling activity was fall in AL4 category which showed very high risk and requires immediate change in working posture. The highest physiological cost of work found in patient handling activity that is EE 9.98 kj/min, HR 117.58 beats/min, TCCW 895.55 beats. In psychological test that is VAS, nurses were reported very severe pain in their neck (18.33%), whereas in FSS score was found 79%. Paired t test was used for statistical analysis to compare mean heart rate of the nurses and found to be highly significant at (P>.001).To improve their health and work life style, possible guidelines were suggested at individual and organizational level to cop up work stress and perform better job demand. They required stress relieving training. Hospital authority must design the hospital working counter ergonomically.

Abstract: Asparagus racemosus is an important medicinal plant commonly called Satavari considered both a general tonic and a female reproductive tonic with ability to increase fertility and vitality. Charak Samhita written by Charak and Ashtang Hridyam written by Vagbhata, the two main texts on Ayurvedic medicines, list Asparagus racemosus as part of the formulas to treat women’s health disorder. Due to its multiple uses, demand for A. racemosus is constantly on the risehowever, the supply is rather erratic and inadequate. Destructive harvesting, combined with habitat destruction in the form of deforestation has aggravated the problem. There is a need for conservation of this plant. To overcome these prevalent problems, the availability of genetically superior and uniform planting material is essential. The seed mediated propagation is unsatisfactory due to dormancy and low germination percentage. This however, decelerates the conservation strategy of this species. Thus efforts were made in this study to break dormancy and improve germination of seeds by different growth regulators for boosting conservation. The TZ (Triphenyl tetrazolium chloride) test showed 97%of viable seeds. The present investigation was carried out to study the influence of different growth substances on seed germination, length of root and shoot and vigour index. The seeds were soaked in different growth regulators like GA3, NAA and KNO3 with different concentration to evaluate their effect on germination at a constant temperature of 250C, it was found that GA3 300 ppm had a highest significant effect on germination as compared to control and all other treatments at a constant temperature on top of the paper substrata, but as the concentration increased above 300 ppm the germination decreased rapidly.
