Abstract: Sixty four genotypes of barley were studied for correlation and path analysis for grain yield and its components. The data were recorded for days to 50% flowering, days to maturity, number of effective tillers per plant, plant height (cm), peduncle length (cm), spike length (cm), number of grains per spike,1000-grain weight (g), biological yield per plant (g), grain yield per plant (g), harvest-index (%), grain plumpness (%), protein content (%) and amylose content (%). Three genotypes, K-762, HUB-211 and NDB 1523 constituted the top non-significant group for highest grain yield per plant among 64 genotypes across the six environments. Grain yield per plant exhibited highly significant or significant and positive phenotypic correlation with harvest index (0.582), biological yield per plant (0.462) and effective tillers per plant (0.275). The estimates of genotypic correlation coefficients among 14 characters were, in general, similar in sign or nature but higher in magnitude than the corresponding phenotypic correlation coefficients. From path analysis,harvest index and biological yield per plantwere found as major direct yield components and days to 50% flowering, days to maturity, effective tillers per plant, plant height, 1000-grain weight, grains per spike and peduncle length, as most important indirect yield components. These characters merit due to consideration while devising selection indices and selection strategy for developing high yielding widely adapted varieties of barley.

Abstract: A field experiment was carried out under All India Coordinated Research Project on Cashew of Orissa University of Agriculture and Technology, Odisha, India to evaluate the cashew hybrids for various nut and apple parameters. The experiment was laid out by adopting Augmented Statistical Design with 71 cashew genotypes including 60 hybrids, 8 parents and 3 check varieties. The analyzed results based on adjusted mean values on nut and apple parameters showed significant variations among the hybrids, parents and check varieties. Cashew genotypes both RP-1 and RP-2 were identified as an ideal female parent while VTH-711/4 and KBN as an ideal male parents for transmission of various nut and apple parameters in cashew towards development of hybrids or varieties.The study also indicated the superiority of male parent, VTH-711/4 towards transmission of cashew apple length, weight, apple to nut ratio(ANR) and above all the TSS towards the progeny.Similarly, red colour pigmentation was dominated over yellow colour among the hybrids, which may be useful in developing coloured cashew apple in future breeding programme.

Abstract: An experiment entitled “Studies on Correlation and Path Coefficient Analysis in Fenugreek (Trigonella foenum-graecum L.)” was carried out at Vegetable Research Farm of the Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad, U.P. during Rabi season 2010-11. The trial was conducted with hundred selection germplasm lines of fenugreek in Augmented Design. The observations were recorded on ten quantitative characters namely plant height (cm), number of branches per plant, days to 50 per cent flowering, number of pods per plant, length of pods (cm) days to maturity, 1000- seed weight (g), yield per plant (g), number of seed per pod and yield q/ha. The genetic correlation coefficients between different characters were similar in sign and nature to the corresponding phenotypic coefficient in the experiment. However, genotypic correlations were higher in magnitude than the corresponding phenotypic value. In the present study seed yield per plant was observed highly significant and positive association with number of branches per plant, 1000-seed weight and significant, correlation with number of pod per plant (at phenotypic and genotypic level.). In the present study the direct effect of several components on seed yield per plant was estimated. A perusal of table 1.0 indicated the direct and indirect effect of different characters on seed yield per plant. At phenotypic level day to maturity followed by days to 50 per cent flowering had high order positive direct effect on seed yield per plant. However, number of seed per pod, number of pod per plant, length of pod and 1000-seed weight exhibited negative direct effect on seed yield per plant, plant height, days to 50 per cent flowering, number of pod per plant, days to maturity, 1000-seed weight had positive indirect effect on seed yield per plant via number of branches per plant. While days to 50 per cent flowering, number of branches per plant, days to maturity and length of pod, had negative indirect effect on seed yield per plant via, number of pod per plant and 1000-seed weight via, number of seed per pod respectively.

Abstract: The study was undertaken to investigate the mineral profile in the embryonic liver of Gaddi sheep. Gravid uteri were collected from the local slaughter houses in and around Palampur. Foetii were then extracted out immediately. CRL (crown rump length) of foetii were recorded for age estimation and accordingly foetii were grouped as group-I (0 to 60 days of age), group-II (61-90 days of age) and group-III (90 to full term). Liver samples were collected from such foetii, dried, digested and analyzed for Zn, Mn, Co, Cu, Fe, Ca, Se and Mo using Atomic Absorption Spectrophotometer. The result showed that the level of Zn was highest (229.00ppm) at 89.06 days of age and lowest (145.00ppm) at 57.00 days of age. Maximum and minimum concentration of Mn was 13ppm and 2ppm, recorded at 135.64 and 54.26 days of age respectively and the mean liver concentration of Mn was significantly lower (P<0.05) in group-I as compare to group-II and group-III. There was no significant difference of hepatic Co concentration among different groups and it ranged from 2.00ppm to 6.00ppm. Cu level was significantly higher (P<0.05) in group-I as compare to group-II and group-III. Concentration of Fe was maximum among all minerals so studied, however its maximum level (239.00ppm) was recorded at age of 83.58 days with significant difference between the groups studied. The levels of calcium showed non-significant difference between the groups-II and III while, the levels of selenium showed significant difference between the studied groups. The concentration of Mo was significantly higher in group-III when compared to group-II and I.

Abstract: The experiment was carried out during summer season of 2012 in split plot design and replicated three times.Plant height at knee high stage only increased markedly due to higher rate of basal nitrogen application resulting significantly taller plant under SPAD based nitrogen management with 75 kg N/ha basal followed by N top dressing at SPAD value at <45 (each time @ 20kg N/ha) and dry matter production at tasselling stage were found to improved significantly under SPAD based nitrogen management compared to blanket split of 150 kg N/ha with 3 splits (½ basal ¼ at 25 DAS + ¼ at 45 DAS) nitrogen application. Thecob weight and baby corn weight increased with higher dose of nitrogen application and in blanket splits of N management with higher dose of application produced higher than lower rate of blanket application and also higher level of N application under both the N management strategies registered significantly higher yield of baby corn over lower level N of application. However, total fodder yield maximum with SPAD based N management due to growth attributes like plant height improved significantly. It should be noted that though net return (Rs.154970) was maximum with the treatment higher dose of blanket application, but B: C ratio was estimate to be highest with SPAD based N application. Seed priming with GA3 did not show significant effect on growth and yield of baby corn. Economics of baby corn production with seed priming also remained unfavorable.

Abstract: An experiment was conducted at Research Farm Jhansi of C.S. Azad University of Agriculture and Technology, Kanpur during Kharif, 2007 on sandy loam soil to study the effect of pruning Albizia lebbeck on understorey cowpea crop and post-harvest soil in agri-silvisystem. Treatment as consisted sole cowpea, cowpea+Albizia no pruning, coppicing at ground, 30 cm, 60 cm height, pollarding at 1.5, 2.0, 2.5m height and lopping. The results revealed that though sole cowpea produced highest grain yield of cowpea (9.56 q/ha), the treatment of coppicing at 60cm remained at par with 8.97 q/ha grain yield and was followed by coppicing at ground level (8.05 q/ha). The treatment of no pruning recorded minimum grain yield 3.02 q/ha followed by lopping 3.86 q/ha grain yield of cowpea. Nutrient uptake in cowpea crop was computed maximum (104.5kg N + 7.6kg P + 40.2kg K/ha) in sole cowpea followed by coppicing at 60cm (104.1kg N + 7.2kg P + 40.9kg k/ha) without significant variation. Lowest uptake of 46.3kg N + 3.7kg P + 19.8 kg/ha was recorded in the treatment of no pruning. Soil pH and EC of post-harvest soil were not much influenced by treatments while O.C., available N and P reduced in sole cowpea and coppicing treatment but increased in the treatment of no pruning and lopping as compared to initial values. Available K reduced in all treatments except no pruning where, it increased from initial value.

Abstract: An attempt was made to determine the extent of genetic variability, based on the evaluation of fifteen genotypes of bell pepper in Randomized Complete Block Design at Experimental Farm, Department of Vegetable Science and Floriculture, HP Agricultural University, Palampur. The data were recorded on traits viz., days to 50 % flowering, days to first harvest (green as well as coloured), number of marketable fruits per plant (green as well as coloured), fruit length (cm), fruit width (cm), pericarp thikness (mm), number of lobes per fruit, average fruit weight (g) (green as well as coloured), number of seeds per fruit, harvest duration (days) (green as well as coloured), plant height (cm) and marketable fruit yield per plant (kg) (green as well as coloured) and quality traits. Mean sum of squares due to genotypes were significant for all the traits except number of lobes per fruit and dry matter. The estimates of PCV and GCV were high for number of seeds per fruit and capsaicin content, which indicated that there is substantial variability ensuring ample scope for improvement of these traits through selection. PCV and GCV values were moderate for number of marketable fruits per plant and marketable fruit yield per plant whereas these were low for most of the traits. For coloured fruits, the estimates of PCV and GCV were moderate for number of marketable fruits per plant, average fruit weight at phenotypic level whereas these estimates were low for days to first harvest, harvest duration and average fruit weight at genotypic level. The estimates of high heritability coupled with high genetic advance were observed for number of seeds per fruit and capsaicin content, which indicated the importance of additive gene action for the inheritance of these traits, and further improvement could be done through phenotypic selection.

Abstract: A field experiment was conducted during kharif season of 2013-14 and 2014 -15in Agriculture Research Station, Dharwad to study the “Genotypic variation in total dry matter, photosynthesis, chlorophyll and total protein and its percent heterosis (mid parent) on yield of cotton hybrids and their parent”. The experiment consisted of thirty hirsutum x hirsutum cotton hybrids and their twenty three parents laid out in randomized block design with three replications on medium black soil. Hybrids and their parents were assessed for total dry weight, photosynthesis, total chlorophyll, total protein and their yield. Seed cotton yield were significant among the hybrids. It ranged from 1111.1 kg to 1986.2 kg/ha. Among the hybrids, RAHH- 12 recorded highest seed cotton yield (1986.2 Kg/ha).Higher seed cotton yield was mainly attributed to its close association with total dry matter (209.48 g/plant), photosynthesis (24.2), total chlorophyll content (1.285) and total protein (50.9) content than the genotype, RAHH-21 recorded lower yield (1111.1 kg/ha). Heterosis for seed cotton yield was maximum in RAHH-27 (72.3%), for total dry matter hybrid, photosynthesis, total chlorophyll content and total protein was recorded more in RAHH-22 (51.5%), RAHH-18 (101.5%), RAHH-30 (149.7%) and RAHH-27 (37.4%). While least heterosis for seed cotton yield was recorded by hybrid RAHH-18 (1.9%).

Abstract: A study using two cytoplasmic male sterile lines (IR-79156Aand Pusa 6A) and five restorers revealed that two major genes (Rf3 and Rf4) govern the fertility restoration, with epistatic interaction that differed from cross to cross. Thecrosses IR-79156A x IET 21519 and Pusa 6A x Sarjoo-52 segregated in ratio of 9:3:4 and 1:1:2 in F2 and BC1 population respectively, indicating the presence of two independently segregating dominant genes showing recessive epistatic interaction of the fertility restoring genes in the genotypes, IET 21519 and Sarjoo-52. The cross, IR-79156A x IET 22218 showed segregation ratio of 9:6:1 in F2 and 1:2:1 in BC1 generation, for pollen fertility indicating that the genotype viz. IET 22218 carry two independent segregating genes with additive type of gene action, the effect of one of the two gene in restoring fertility appeared to be stronger than the other. The crosses IR-79156A x MTU-7029 and Pusa 6A x IET 22202 given segregation behavior of 12:3:1 in F2 progeny and 2:1:1 genetic ratio in test cross progeny suggesting the presence of two dominant genes with dominance epistasis in the fertility restoring genes in the genotypes MTU-7029 and IET 22202.

Abstract: The study of genetic divergence among the 46 genotypes of brinjal (Solanum melongena L.) was carried out using Mahalanobis D2 statistics. The 46 genotypes were grouped into seven different non over lapping clusters. Cluster III had highest number of genotypes (26) followed by cluster I (11), cluster II (5) while, rest of the four clusters were monogenotypic. The intra cluster D2 values ranged from 0.00 (monogenotypic clusters IV, V, VI, VII) to 119.78 (cluster I). The maximum inter-cluster distance(178.89)was observed between clusters (NDB-51) to VII (NDB-36) which suggested that members of these two clusters were genetically very diverse from each other and crosses between these may give rise heterotic F1 andtransgressive segregates.The inter-cluster values between cluster II and cluster VII (156.95), cluster IV to VII (125.00), cluster I to VII (108.47), cluster II to V (96.22), cluster III to VI (93.20)were also very high. The higher inter-cluster distance indicated greater genetic divergence between the genotypes of these clusters while lower inter-cluster values between the clusters suggested that the genotypes of the clusters were not much genetically diverse from each other. The cluster means for different traits indicated considerable differences between the clusters. Cluster IV showed maximum mean values for the flower per inflorescence and earliest mean values for days to 50% flowering, cluster V showed maximum mean values for the fruit weight, fruit circumference, fruit per plant, marketable fruit yield per plant, unmarketable fruit yield per plant and total fruit yield per plant. Cluster VI showed maximum mean values for the plant height and primary branch. Cluster VII exhibited maximum mean values for the polar length of fruit. Among the eleven quantitative traits fruit circumference (cm) contributed maximum (34.59%) towards total genetic divergence in the genotypes.

Abstract: A field experiment was conducted during Rabi season of 2011-12, in organic farm at NAU, Navsari (Gujarat), to study the different intercropping in banana on physico-chemical and biological properties in clayey soil under organic farming. The result revealed that post harvest evaluation of physical properties of soil was significantly influenced due to the various intercropping treatments of organic manures and favorable significant effect on soil fertility. Soil microbial population bacteria, fungi and actinomycetes were examined after harvest of banana .The different organic treatments significantly enhanced the microbial count during experimentation. However, with high levels of organic manure doses, lower the microbial count was recorded. The maximum CO2 evolved was obtained with 100% RDN through organic manure treatment as compared to 50% RDN. Significantly the highest content of soil organic carbon (0.93 %), available N (305.9 kg ha-1), P2O5 (62.3 kg ha-1), K2O (323.8 kg ha-1), S (13.1 mg/kg) and Fe (22.6 mg kg-1) were observed in treatment T5 of Banana + Garlic @ 100% RDN. However, the highest Mn (33.4 mg kg-1) content was registered with the treatment T3 Banana + onion @ 100% RDN whereas the higher Zn (0.96 mg kg-1) and Cu (4.82 mg kg-1) content were found under treatment T9 Banana + Beet @ 100% RDN. It was also inferred that under organic farming, application of nutrients through organic manures also improved the physical, chemical and biological status of soil which helps in sustainability of soil fertility.

Abstract: An experiment conducted at Nagarjun Medicinal Plants Garden, Dr. P.D.K.V., Akola during kharif 2009-10 and 2010-11 under randomized block design with thirteen treatment combination replicated three times. The experimental soil was calcareous in nature and moderately alkaline in reaction. The fertility status of the soil was moderate in organic carbon, low in available nitrogen and available phosphorus and very high in available potassium while the soil micronutrient contents (Zn, Fe, Mn, Cu) were above the critical level. The treatment imparted to Java citronella were control (no fertilizer/manure), 5 t FYM ha-1, 10 t FYM ha-1, 80:20:40 kg NPK ha-1, 100:30:60 kg NPK ha-1, 140:40:80 kg NPK ha-1, 5 t FYM + 80:20:40 kg NPK ha-1, 5 t FYM + 100:30:60 kg NPK ha-1, 5 t FYM + 140:40:80 kg NPK ha-1, 10 t FYM + 80:20:40 kg NPK ha-1, 10 t FYM + 100:30:60 kg NPK ha-1, 10 t FYM + 140:40:80 kg NPK ha-1 and 100 kg N through FYM (based on FYM analysis). The results revealed that maximum availability of macronutrients (N, P, K, S) was observed through the application of 10 t FYM + 140:40:80 kg NPK ha-1 and the highest micronutrients availability of Fe, Mn, Zn and Cu with the application of 100 kg N through FYM. Hence, from the two years of experimentation and among the different treatments of nutrient management it can be concluded that, application of FYM @ 10 t ha-1 in combination with chemical fertilizer @ 140:40:80 kg NPK ha-1 was found more beneficial way of nutrient management to improve the availability of macro and micro nutrients status of soil under Java citronella.

Abstract: In present investigation, a wide range of variation in estimates of heterobeltiosis and standard heterosis in positive and negative direction was observed for grain yield per plant and its contributing components. In case of grain yield per plant heterobeltiosis ranged from -26.87 (NDRK 5096/ Jaya × CSR 10) to 10.78 (IR2-9-B-1-5/ Jaya × CSR 10) and standard heterosis varied from -22.18 (NDRK 5096/ Jaya × CSR 10) to7.03 (IR2-9-B-1-5/ Jaya × CSR 10) over SV1. NDRK 5026/Jaya, NDRK 5026/CSR10, NDRK 5026/ Jaya × CSR 10, NDRK 5096/ Jaya × CSR 10, NDRK 5088/ Jaya × CSR 10 and CSRS (C) 52-1-1/ Jaya × CSR 10 were found highly significant over standard variety SV2 (CSR 10), while, NDRK 5096/Jaya, NDRK 5096/CSR10, NDRK 5088/Jaya and NDRK 5088/CSR10 were significant over SV2 for grain yield per plant. The estimates of heterosis were attributed to genetic interaction arising from both additive as well as high degree of non additive gene action for major physiological traits. Two physiological traits viz., biological yield per plant and harvest index followed by filled spikelets per panicle, spikletes per panicle, 1000grain weight, L/B ratio and size of flag leaf remained as major contributors to heterobiltiosis and standard heterosis(as has been observed inNDRK 5026/ Jaya). These hybrids needs commercial exploitation for sustainability under sodic soil.

Abstract: The aim of the study was to evaluate the effect of different cooking (i.e. water and steam) methods on the antioxidant properties and bioactive components in potato flour. Potato flours prepared by different cooking methods were screened for nutritional (moisture, starch, fat, protein & ash) analysis, phytochemical (ascorbic acid & total phenolics) analysis, total antioxidant capacity measured by DPPH radical scavenging method and color (L*, a*, b*) analysis. Results showed that nutrient components of potato flours prepared from both cooking methods were almost similar to those of raw tubers, indicating a non-significant effect of processing. However, processing of raw potato tubers into flour resulted in a significant reduction in phytochemical content and total antioxidant capacity, regardless of the cooking method. Methanolic extracts of flour obtained by water-blanched potato exhibited higher reductions in total phenolics and antioxidant activity compared to flour obtained by steam cooking. Cooking in water caused a leaching effect on the antioxidant phytochemicals while steam cooking resulted in retention of these bioactive compounds. Pasting profile of potato flours revealed lower viscosities in steam-cooked flour due to higher gelatinization of starch during processing, indicating their wide application in food industry. This study revealed that steaming appeared to be the most promising method for preserving the bioactive composition of potato during processing.

Abstract: The experiment under the present investigation “studies on general combining ability effects (gca effect) in tomato (solanumlycopersicuml.) was carried out during the period of October, 2011 to April, 2014. The field experiments were carried out at Vegetable Research Farm of the Department of Vegetable Science, Kalyanpur, C.S. Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh. The farm is situated at 260 290 “35 N latitude and 800 180 25” E longitude at an elevation of 125.9 M above mean sea level. All laboratory analysis has been conducted in the Department of Vegetable Science and Department of Biochemistry, C.S. Azad University of Agriculture and Technology, Kanpur.All possible 45 F1s along with 10 parents were grown in Randomized Block Design (RBD) with three replications during 22-10-2012 to 20-04-2013. The experiment comprising 45 each of F1 and F2 along with 10 parents were transplanted in Randomized Block Design with three replications during 15-10-2013 to 14-04-2014. Parents and F1s were transplanted in two rows with 10 plants in each row while F2swere transplanted in four rows with 20 plants in each row with 75 x 60 cm spacing in each replication. The observations were recorded for plant height, days to flowering, number of fruit bearing branches per plant, Days to maturity, number of clusters per plant, number of fruit per cluster, Fruitlength, Fruit width, number of locules per plant, number of fruits per plant , Yield per plant, T.S.S., dry matter, lycopene, ascorbic acid, acidity in terms of citric acid and TLCV incidence I, II, II, IV and V stages were taken only for parents and their best crosses in tomato. Consisting general combining ability effects may prove advantageous while evaluating varieties for combining ability. Further the varieties showing good general combining ability effect for particular component may be used in breeding improvement for particular component indicating thereby effective improvement in yield. Varieties H-24, Pusa Rohini and Type-1 showing good general combining ability effects for TLCV tolerance and K.S.-229, K.S.-7 and Azad T-6 for yield and their component appear to be worthy for exploitation in practical plant breeding. Thus, it is suggested that population involving these lines may be developed through multiple crossing for isolating high yielding disease resistant varieties.

Abstract:Among the several genes involved in the carotenoid biosynthetic pathway crtRB1 is one of the crucial gene with three polymorphic sites viz., 5’TE, InDel4 and 3’TE, significantly associated with variation for endosperm carotenoids in maize. 3’TE (Transposable element) polymorphism of crtRB1 gene has three alleles, among which 543bp allele (allele1/favourable allele) alone can double the -carotene concentration in maize endosperm. There is a strong relation between allele1 of crtRB1-3’TE and -carotene concentration in maize kernel. This enables the opportunity to use marker assisted selection (MAS) for allele 1 of crtRB1-3’TE gene in enhancing carotenoid breeding programme. To identify the maize inbreds carrying allele 1 of crtRB1-3’TE we screened seventy inbred lines using crtRB1-3’TE gene specific marker and identified four inbreds (MGU 23379, MGU 23207, BAJIM 12-11 and CM 150) possessing allele1.

Abstract:A field experiment was conducted to find out the effect of pruning intensity, foliar feeding of P.G.R. and micro nutrients on physico-chemical attributes of phalsa (Grewia subinaequalis) fruits. Significantly higher fruit size (length and breadth) was analyzed by foliar spray of ZnSO4 @ 0.4 per cent. Pruning levels also had significant effect on fruits size. The maximum weight of fifty fruits was recorded with foliar feeding of ZnSO4 @ 0.4 per cent. Higher weight of fruits was also weighed with pruning at 50cm above from the ground level. Effect of plant growth regulators and micro-nutrients spray was non-significant to influence pulp stone ratio. Significantly higher TSS value in fruits was analyzed by foliar spray of ZnSO4 0.4 per cent and the maximum TSS was recorded with pruning at 50 cm above from the ground level. The maximum reducing, non-reducing and total sugars have been observed with foliar spray of ZnSO4 0.4 per cent. Remarkable reduction in acidity of fruit was observed with the foliar spray of ZnSO4 0.4 per cent. The foliar spraying of ZnSO4 0.4 per cent was found significantly most effective in increasing ascorbic acid content of fruit. Employing pruning at 50 cm also showed higher ascorbic acid content.

Abstract: The concept of sacred and nature have long been interlinked. Various cultural aspects such as religion, faith, traditions bring people closer to nature and the natural environment. Sacred Groves is the example of such cultural landscapes that exist today. The Research article mainly deals with the significance of such sites to the environment and the deep rooted significance it has to the people. These sacred groves play an important role in biodiversity conservation and environmental protection. There are many differences between the establishments of sacred groves, but the underlying significance is the same. Sentiments, emotions play an important role in landscape planning and management. Hence the people and communities living at these sites need to be involved in any planning activity or decisions. The conservation of the environment should appeal to the sentiments of the people; the need to be ‘with nature’ should be used in the preservation of sacred groves.
