Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Assessment of genetic diversity and path analysis in pumpkin (Cucurbita moschata L.) under tarai of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-12) Pooja; Maurya, S.K.
    The present experiment was conducted at Vegetable Research Center of G.B.P.U.A. & T., Pantnagar during spring-summer season of two subsequent years, 2018 and 2019. 40 genotypes including two checks (Pusa Vikas and Pusa Biswas) were laid out in Randomized Block Design with three replications. Observations were recorded on twenty three quantitative and qualitative characters. Analysis of variance showed significant differences for most of the traits except average fruit weight, diameter of main vine and carotenoid content during both the seasons. A narrow range of difference between GCV and PCV was reported for all the traits which indicate these traits are mostly governed by genetic factors with least environmental influence on phenotypic expression. High heritability accompanied with high genetic advance was found for traits days to first female flower, days to first harvest, percent fruit set per plant, number of seeds per fruit and non-reducing sugars, suggest that there is a high scope of improvement in these characters through direct phenotypic selection. Traits such as main vine length, diameter of main vine, fruit set percent, average fruit weight, fruit diameter, flesh thickness, central cavity and carotenoid content showed significant positive association with yield trait. Average fruit weight, fruits per vine, main vine length and diameter of main vine reported to exhibit direct positive association with yield per plant. Out of 7 principle components identified, first three components contributed about 50% in total divergence. All the 40 genotypes of pumpkin were grouped into 7 different clusters. In general inter cluster distances were higher than intra cluster distances, indicating presence of sufficient genetic diversity among the genotypes belonging to the different clusters. Based on fruit yield performance of 40 genotypes under study, four genotypes namely PPU-27 (403.0 q/ha), PPU-16 (392.8 q/ha), PPU-14 (380.1 q/ha) and PPU-12 (365.0 q/ha) found promising for yield as against standard check Pusa Biswas (355.6 q/ha).Therefore, it is recommended that these three genotypes may be utilized as commercial cultivar after following standard release procedure as well as for future breeding programme in pumpkin.

Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during rabi season of 2016-17 and 2017-18. The experiment was laid out in Three Factorial Randomized Block Design (FRBD) with one extra treatment consisting of two fertigation system viz., S1 (surface fertigation) and S2 (sub-surface fertigation), three fertigation scheduling viz., L1 (15% N:10% P2O5: 10% K2O of RDF between 15-30 days after planting (DAP), 40% N, P2O5 and K2O of RDF between 30-45 DAP, 40% N, P2O5 and K2O of RDF between 45-60 DAP, 15% N, 10% P2O5 and 10% K2O of RDF between 60-75 DAP), L2 (25% N, P2O5 and K2O of RDF between 15-30 DAP, 30-45 DAP, 46-60 DAT and 60-75 DAP) and L3 (20% N, P2O5 and K2O of RDF between 15-30 DAP, 30% N, P2O5 and K2O of RDF between 30-45 DAP, 30% N, P2O5 and K2O of RDF between 45-60 DAP and 20% N, P2O5 and K2O % of RDF between 60-75 DAP) and six fertigation treatment viz., T1 (120% of RDF), T2 (100% of RDF), T3 (80% of RDF), T4 (60% of RDF), T5 (40% of RDF), T6 (without fertilizer) along with one an additional treatment T7 (farmers practice) replicated thrice, During the study, various observations on growth parameters, various yield and yield attributing parameters along with quality parameters, nutrient uptake and water use efficiency was also recorded. Besides this, to assess the profitability of different treatment combinations, cost of cultivation, net return was also worked out. The findings of two year investigation revealed that performance of potato was significantly influenced by different fertigation system, fertigation scheduling and fertigation treatment. Among fertigation system, sub-surface system was found superior, among the three fertigation scheduling, schedule 3 was found better and among fertigation treatment, T1 : 120% of RDF was found best in terms of various growth, quality parameters, nutrient uptake in plant, water use efficiency and marketable yield (355.12 and 388.57 q ha-1), net return (`190623 and ` 222400). Based on the overall performance, it could be concluded that under tarai conditions of Uttarakhand, application of sub-surface fertigation @ 192: 120: 144 kg N, P2O5 and K2O per ha through schedule L3 (20: 30: 30: 20% N, P2O5 and K2O of RDF at 15-30: 30-45: 45-60: 60-75 DAP) gave maximum tuber yield and net return with water saving of 68.6% in potato. Hence, the same may be recommended for commercial cultivation.

    The present investigation was undertaken to standardize the NPK fertigation in broccoli at Vegetable Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during October to February for two consecutive years i.e. 2016-17 and 2017-18. The experiment was laid out in two factorial randomized block design with one additional treatment consisting of five fertigation levels viz., F1 :120 percent of RDF, F2 : 100 per cent of RDF, F3: 80 per cent of RDF, F4 : 60 per cent of RDF and F5: 40 per cent of RDF and three fertigation scheduling viz., S1 : 25, 15 and 20 per cent N, P2O5 and K2O of fertigation levels between 5-20 days after transplanting (DAT), respectively, 40, 15 and 25 per cent N, P2O5 and K2O of fertigation levels between 21-36 DAT, respectively, 20, 50 and 40 per cent N, P2O5 and K2O of fertigation levels between 37-52 DAT, respectively, 15, 20 and 15 per cent N, P2O5 and K2O of fertigation levels between 53-68 DAT, respectively, S2 : 25 per cent of each N, P2O5 and K2O between 5-20 DAT, 21-36 DAT, 37-52 DAT and 53-68 DAT, respectively and S3: 20, 20 and 20 per cent N, P2O5 and K2O of fertigation levels between 5-20 DAT, respectively, 40, 30 and 20 per cent N, P2O5 and K2O of fertigation levels between 21-36 DAT, respectively, 30, 30 and 30 per cent per cent N, P2O5 and K2O of fertigation levels between 37-52 DAT, respectively and 10, 20 and 30 per cent N, P2O5 and K2O of fertigation levels between 53-68 DAT, respectively, along with one control (soil application of RDF with flooding) replicated thrice. The findings of present investigation revealed that performance of broccoli was significantly influenced by different drip fertigation levels and scheduling. Among the different fertigation levels, fertigation of broccoli at 120 per cent of RDF (F1) was found best with respect to plant growth characters, root parameters, maturity parameters, quality, nutrients content & nutrients uptake in plant. Whereas, fertigation at 100 percent of RDF (F2) was found best with respect to head parameters, water use efficiency, yield (15.20 t/ ha), net return (` 158462.6 and 152788.8) and benefit cost ratio (3.19 and 3.11). Among the three scheduling tested, scheduling S1 was found best in terms of growth parameters, root parameters, head parameters, nutrient content and uptake in plant, water use efficiency, yield (13.83 t/ ha), net return (` 141603.5 and 138284.8) and benefit cost ratio (3.09 and 3.05). Fertigation at 100 percent RDF (F2) through scheduling S1 recorded significantly higher yield (15.43 t/ ha and 15.09 t/ ha), net return (` 160061.4 and 155002.19) and benefit cost ratio (3.24 and 3.17) and was best treatment combination. Based on the overall performance, it could be concluded that under tarai conditions of Uttarakhand, fertigation of broccoli at 120:60:60 kg N, P2O5 and K2O per ha (F2) through scheduling S1 is the best and most economical for cultivation of broccoli. Hence, the same is recommended for commercial cultivation.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Bhatt, Bhawana; Manoj Raghav
    The present investigation was conducted at Pantnagar Centre for Plant Genetic Resources (PCPGR) of the G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during Rabi season of the year 2016-17 and 2017-18. The experimental material comprised of thirty seven genotypes of fenugreek including one check variety (Pusa Early Bunching). The accessions were evaluated in Randomized Block Design to study the genetic parameters through morphological and nutraceutical traits. Observations were recorded for 16 quantitative traits viz., number of primary branches per plant, number of leaves per plant at 30, 45 &60 days after sowing, plant height, days to first flowering, node of first flowering, days to 50 % flowering, days to seed maturity, number of pods/plant, pod length, pod width, number of seeds/pod, 1000-seed weight, green leaf yield/plant and seed yield/plant as well as for 9 nutraceutical traits viz., phosphorus, potassium, iron, copper, manganese, zinc, ash, protein and diosgenin content. Analysis of variance revealed significant differences among genotypes for all traits. The estimates of PCV were found higher than the corresponding GCV for all traits. The genotypes namely, PCPGR-GP-2011-572, PFG-9, PCPGR-5984 and PFG-42 found promising genotypes for seed yield per plant while PCPGR-GP-2011-248 and PCPGR-5984 found desirable for green leaf yield per plant. Among nutraceutical traits, for phosphorus content PCPGR-GP-2011-196, for potassium content PCPGR-GP-2011-158, for iron content PFG-16, for copper and manganese content PFG-18, for zinc content PCPGR-7928, for ash content PCPGR-GP-2011-285, for protein content PCPGR-7368 and for diosgenin content PCPGR-GP-2011-248 found best genotypes. High heritability coupled with0high genetic advance as per cent of mean was recorded for primary branches/plant, number of leaves /plant at 30, 45 & 60 DAS, plant height, node of first flowering, number of pods/plant, 1000-seed weight, leaf yield/plant, seed yield/plant, potassium, iron, copper, manganese, zinc, ash, protein and diosgenin content. Number of pods/plant, 1000-seed weight, green leaf yield/plant, pod width and plant height showed highly significant positive correlation as well as positive direct effect on seed yield/plant. Genetic diversity analysis using D2 statistics classified 37 genotypes into nine clusters. The traits like, number of pods/plant, number of leaves/plant at 60 DAS, days to first flowering, plant height, seed yield/plant, 1000-seed weight, green leaf yield/plant and number of seeds/pod showed maximum contribution towards genetic divergence. Thus, significant genetic variability and considerable amount of genetic diversity is present among the fenugreek genotypes under study and selection of the genotypes on the basis of these characters will be highly rewarding.

    Heterosis and combining ability studies in Brinjal (Solanummelongena L.) for quantitative and quality traits
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Mallesh, Sanganamoni; Singh, Y.V.
    The experiment was conducted during 2016-2017 on brinjal (Solanum melongena L.) with 28 F1s, which were developed through half diallel method of hybridization between 8 parents and arranged in randomized block design with three replications each. The prime objective of the investigation was to assess the genetic capability of eight parental lines towards their compatibility among themselves to yield better cross combinations for earliness, yield and quality traits. Field experiment was conducted at Vegetable Research Center of the university and lab analysis was done at department laboratory. Data were recorded on traits statistical analysis was done to estimate genetic variability, association of characters, heterosis and combining ability. Analysis of variance reveals existence of sufficient variability in experimental material. Most of the characters under study were amenable to direct selection for further improvement by expressing high GCV and PCV with less difference between them. This trace differences may be due to low environmental influence on those traits under study. High heritability coupled with moderate to high genetic advance as per cent of mean was reported for all the characters. Significantly positive correlation of fruit yield per plant was found with weight of healthy fruits per plant, total number of fruits per plant, weight of infested fruits per plant, number of healthy fruits per plant, early yield per plant, number of infested fruits per plant, fruit length, average fruit weight, fruit diameter and fruit length: diameter ratio. This positive association may be through its direct positive effects through number of infested fruits per plant, total number of fruits per plant and weight of healthy fruits per plant. Heterosis studies concluded as hybrids, IBWL-1 x PR, IBWL-1 x PB-6 and PS x PB-101 were found promising for earliness while, for fruit yield, IBWL-1 x PLP-1, PLP-1 x PB-6, PS x PLP-1 and PS x PB-101 were found effective. PLP-1 x PB-101, PR x PB-101, IBWL-1 x PB-101 and PPR x IBWL-1 crosses were found best for quality traits. PB-101 was identified as a best general combiner for maximum number of yield and quality related traits followed by PLP-1 and PB-6. The best specific combiners were PLP -1 x PB-6 followed by PS x PLP-1, IBWL-1 x PLP-1 and PLP-1 x PB-101 for most of the yield and quality traits. These crosses can be exploited for deriving desirable recombinants in segregating populations.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Kohli, Karishma; Tripathi, Shailesh
    The present investigation entitled “Studies on efficacy of composite edible coatings on postharvest quality and shelf life of guava (Psidium guajava L.)” was conducted in the Postharvest Laboratory, Department of Horticulture, College of Agriculture, G.B. Pant University of Agriculture and Technology, Pantnagar. The main aim of the study was to investigate the effects of different composite edible coating treatments like olive oil, Aloe vera gel, xanthan gum, sodium alginate and carboxymethyl cellulose as a base coatings with calcium gluconate as a texture enhancer and ascorbic acid as an antioxidant at varying concentrations on physicochemical characteristics and shelf life of guava cvs. Sardar and Lalit. The experiment was conducted in two factorial completely randomized design with 11 treatments and 3 replications. The trial was carried out at ambient temperature 27-29°C at 91% R.H in winter seasons of 2017 and 2018. The changes in physiological loss in weight, decay, total soluble solids, titratable acidity, ascorbic acid, total sugars, TSS: acid ratio, sugar: acid ratio, pH, total chlorophyll content, superoxide dismutase activity, total flavonoids content, phenolic content, antioxidants, polyphenoloxidase activity and sensory characters like fruit appearance, colour, flavour, texture, taste and overall acceptability were recorded for each treatment over a storage period of 15 days after harvesting, starting from harvest day up to 15th day of storage during the both winter seasons. Olive oil composite edible coatings were most effective in reducing weight loss, fruit decay and maintaining organoleptic qualities than other treatments. Higher total soluble solids, ascorbic acid, total sugars, superoxide dismutase activity, phenolic content and antioxidant activity were recorded in fruits coated with olive oil 100% + texture enhancer 0.5% and olive oil 100% + texture enhancer 0.5% + antioxidant 0.1% treatments in cv. Sardar as compared to cv. Lalit. Hence, it can be concluded that olive oil composite edible coatings coated fruits in cv. Sardar fruits retained more desirable texture and other postharvest quality attributes as compared to cv. Lalit under ambient storage conditions at different storage intervals.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-06) Lavlesh; Manoj Raghav
    The present investigation was undertaken to evaluate the “Effect of manual and chemical methods of weed management on potato (Solanum tuberosum L.)” at Vegetable Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during rabi season of 2014-2015. The experiment was laid out in Randomized Block Design consisting of seven treatments replicated thrice. During the study, observations on per cent emergence, plant height, number of haulms per hill, fresh and dry weight of weeds, number of monocot, dicot and total number of weeds at 30, 45, 60 days after planting (DAP) and at de-haulming stage, fresh and dry weight of plants at de-haulming stage were recorded. In addition, grade wise number and weight of tubers per plot and per hectare, total number of tubers and total tuber yield per hectare, marketable yield per hectare, harvest index, dry matter content, protein content and specific gravity of tubers, nitrogen, phosphorus and potash uptake by haulm, tuber, plant and weeds were also recorded. Besides this, to assess the profitability of treatments, cost of cultivation, net profit and benefit: cost ratio were also worked out. The findings of present investigation revealed that performance of potato crop was significantly influenced by different weed control treatments. Among all treatments, herbicide metribuzin @ 0.75 kg a.i./ha pre emergence (T6) was found best with respect to overall plant growth, yield and quality parameters with a total yield (305.43 q/ha), net return (`147497.36) and benefit: cost ratio (1.93). Based on overall performance, it could be concluded that under prevalent climatic conditions of Uttarakhand tarai region, herbicide metribuzin @ 0.75 kg a.i./ha pre emergence is the best in terms of higher and economic yield of potato. Hence, recommended for commercial cultivation, provided all other scientific management practices are followed.

    Assessment of genetic and molecular diversity in tomato (Solanum lycopersicon L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-07) Dhyani, Shivani; Singh, Dhirendra
    The present investigation was conducted at the Vegetable Research Centre (V.R.C.), Govind Ballabh Pant University of Agriculture & Technology, Pantnagar during the year 2016 and 2017. The laboratory experiments were carried out at the National Agriculture Innovation Project (NAIP), Department of Vegetable Science. The experimental material comprised of fifty three genotypes of tomato including three checks, namely, PT-3, Arka Vikas and Roma which were evaluated in Augmented Block Design-II having five blocks with 60 x 50 cm spacing. Observations were recorded for twenty four traits. Data were analysed statistically for mean, variation, heritability in broad sense, genetic advance, character association, path coefficient, non-Hierarchical Euclidean Cluster Analysis, principle component analysis and molecular marker analysis. Most of the characters showed significant differences among check varieties except fruit locules which showed non-significant differences. The genotypes PT-11, PT-2009-08, Pant selection-04, PT-2009-10 and PT-41 recorded maximum yield. The phenotypic coefficient of variability and genetic coefficient of variability was higher than that of environmental coefficient of variability. High heritability coupled with high genetic advance as per cent of mean was recorded for fruit pericarp thickness. Fruit yield per plant was highly significant and positively correlated with internodal length, fruit length, fruit diameter and with fruit weight. The fruit weight had highest positive direct effect on the fruit yield followed by fruits per plant and plant height at first picking. Non-hierarchical Euclidean cluster analysis for yield and its contributing traits classified all 53 genotypes of tomato including 3 checks into eight non overlapping clusters. The first eight principle components recorded a variation of 88.75 per cent among the various genotypes of tomato. SSR primers used in 20 genotypes of tomato studied for molecular diversity. Thus, it can be concluded that significant variability and diversity was present among the tomato genotypes studied, which indicated the existence of considerable scope for the improvement of these genotypes through selection and hybridization programme and it would be more rewarding to select genotypes on the basis of characters like fruit length, secondary branches per plant, fruit pericarp thickness, plant height at first picking, flower per cluster, fruit set percentage, leaf area and fruit weight, which have direct positive effect on fruit yield.

    Studies on fruit development and determination of maturity indices in ber (Zizyphus mauritiana Lamk.) cultivars under Tarai region
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Ankit Kumar; Singh, Omveer
    The present investigation “Studies on fruit development and determination of maturity indices in ber (Zizyphus mauritiana Lamk.) cultivars under Tarai region” was conducted on existing 40 years old ber orchard at Horticulture Research Centre, Patharchatta, G. B. Pant University of Agriculture & Technology, Pantnagar, U.S. Nagar, Uttarakhand, India during the cropping season of 2017-18 and 2018-19. Eight ber cultivars viz., Chhuhara, Chinese, Kalagola, Nazuk, Sanaur-2, Sanaur-4, Umran and ZG-2 were selected for the study. Three trees per cultivar were selected, each of which was considered as a replication. The experiment was laid out in two factor Randomized Block Design (RBD) with three replications. Sampling dates and cultivars were considered as the treatments. There were 11 sampling dates commences at 28 days after full bloom (DAFB) to 168 DAFB and observations were taken at biweekly interval for determining the changes in growth pattern and quality attributes in ber cultivars. During the last two months of maturity the fruit samples were picked at a narrow interval of 7 (weekly) days from 112 DAFB so as to fix up the appropriate maturity indices under tarai conditions in terms of their biochemical and functional attributes while sensory attributes were judged from 126 DAFB. Twenty fruits at every sampling date from each tree were plucked randomly from all directions of the tree collected in a polyethylene bags and carried to the postharvest laboratory of the Department of Horticulture and analyzed for physical, biochemical and functional characteristics on the day of harvesting. Significant differences in terms of physical, computational, bio-chemical, functional and sensory quality attributes were observed among the ber cultivars during the span of study. Finding of the study showed a characteristic double sigmoid growth pattern in terms of fruit size, weight, volume, flesh: stone ratio and TSS in most of the cultivars. On the basis of various physico-chemical, functional and sensory quality attributes, most of the cultivars attained their physiological/horticultural harvest maturity at 154 to 168 days after full bloom except Nazuk and ZG-2 which got their harvest maturity at 140 DAFB. DAFB, TSS, TSS: acid ratio, specific gravity, firmness and total carotenoid content were found to be the reliable maturity indices of maturity in ber cultivars. Therefore, the present study will be useful to have multiple indices to fulfill the needs of growers, distributors, consumers and also for pharmaceutical and nutraceutical industry.
