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.

ThesisItem Open Access Genetic divergence studies for yield and yield attributes in cowpea [Vigna unguiculata (L.) Walp.](G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2022-06) Belwal, Ankita; Singh, J.P.Cowpea [Vigna unguiculata (L.) Walp.] is a leguminous vegetable crop mainly grown in both kharif, spring and summer season in most parts of India. Cowpea is an essential component of sustainable cropping systems in the sub-humid tropics and generally, dries regions across the globe. Though, wide genetic diversity exists in this crop with regards to the yield and yield contributing characters. Forty genotypes (IC-559405, IC-628893, Kashi Gauri, IC-628900, COPBVAR-3, IC- 202826, IC-628899, IC-628895, EC-97306, EC-390241, IC-628897, EC-19736, EC-528382, Kashi Unnati, EC-390216, EC-390223, IC-202718, IC-202824, COPBVAR-2, IC-51154, EC-472272, IC-337932, IC-536635, IC-202790, IC-201098, EC-37588, PVCP-21, EC-572715 EC-202858, IC-628894, EC-390628, EC-97738, IC-209711, IC-331250, IC-201095, WB-9, COPBVAR-4 and COPBVAR-6) with two check varieties Pusa Komal and Kashi Kanchan were evaluated in Randomized block design during Kharif season 2021 at the vegetable research centre, G.B. Pant University of Agriculture and Technology, Pantnagar, to study the twenty one growth and yield related characters namely., Growth Pattern, Leaf size, Pod shape, Pod colour, Seed colour, Plant height (cm), Number of primary branches, Days to first flowering, Days to 50% flowering, Days to first pod emergence, Days to first pod maturity, Number of pods per cluster, Number of seeds per pod, Pod length, Green pod weight, 100 seed weight, Number of pods per plant, Number of pods per plot, Green pod yield per plant, Green pod yield per plot, Green pod yield per hectare and five quality characters namely protein content, total phenols, ash content, antioxidant activity and elemental analysis. The pooled data were subjected to statistical analysis. The result of analysis of variance revealed that difference among cowpea genotypes was highly significant for all the characters. The highest value of PCV and GCV obtained for plant height followed by green pod yield per plant. High heritability and high genetic advance as percentage of mean reported in the character plant height (cm) followed by green pod yield per plant. High positive significant correlation for green pod yield per hectare (q) reported by pod length (cm), 100 seed weight (g), number of pods per plot, number of pods per plant, green pod weight, green pod yield per plant and green pod yield per plot. Path coefficient analysis showed positive direct effect on green pod yield per hectare (q) was exhibited by green pod yield per plot, days to 50% flowering, 100 seed weight. Analysis of quality characters indicated that cowpea served as excellent source of protein and good source of minerals and antioxidants. On the basis of the study conducted, it was concluded that there was a wide range of variance between the genotypes which was considered as scope for improving the cowpea cultivar through selection. Selection based on the characters like plant height (cm), pod length (cm), number of pods per plant, green pod yield per plant will substantially increase the yield. Out of forty genotypes EC-572715, EC-390216, WB-9, IC-628899, COPBVAR-3, EC-97306, EC-390216, IC-628899, EC472272, COPBVAR-3, EC-390241, COPBVAR-6 and Kashi Kanchan yields were found to be superior and some genotypes namely., EC-572715, EC-390216, WB-9, IC-628899, COPBVAR-3, COPBVAR -6 and Kashi Kanchan are identified as promising ones for their performance for yield related characters and can be used for the improvement of the cowpea cultivars in breeding programmes.ThesisItem Open Access Effect of Silica Oxide Concentrations on Vegetative Growth, Flowering and Corm Attributes of Gladiolus under Tarai Conditions(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2022-07) Fartiyal, Pooja; Bhuj, B.DThe present experiment was conducted at Model Floriculture Centre, GBPUA&T, Pantnagar, Uttarakhand, during 2020-21. Experiment was laid out in factorial concept of randomized block design (RBD) in open field conditions. The objectives of investigation were to study the effect of silica oxide on growth, flowering, corms, cormels and vase life of gladiolus. The treatments used for soil application were pre-planting soil application of SiO2 (0, 25, 50, 75 and 100 kg/ha) and for foliar application suspension was made of the same in water at 0% (water spray), 1% (4.7 g/m2), 2%(9.4 g/m2 ) and 3% (14.1 g/m2) of silica oxide and were sprayed at 30 and 60 days after planting. The medium sized (4.0- 4.5cm) corms were used as experimental material of gladiolus cultivar viz. “Rose Supreme”. The results revealed that most of the vegetative parameters like plant height, number of leaves and flowering parameters viz., days to spike initiation and flowering, floret size, spike and rachis length, number of floret per spike as well as vase life and corm and cormel parameters were found highly affected by the silicon oxide and were found to be best with the combined application of silica oxide as 75kg/ha soil application with 3% foliar application of silica dioxide. The number of corms, weight and diameter of corm, numbers of cormels and weight of cormels were also improved with the same treatment. Leaf nutrient analysis revealed higher concentration of silicon in the leaves at first floret colour showing stage which help in quality enhancement. hence, it is inferred that the combined application of silicon oxide (soil and foliar application) effectively enhanced the quantity and quality of gladiolus flowers, corms and cormels.ThesisItem Open Access Response of plant growth retardant (Mepiquat Chloride 5% AS) in Chilli cv.

The findings of present investigation revealed that the performance of chilli cv. Pusa Jwala was significantly influenced by different plant growth retardant treatments. Among all treatments, Plant Growth Retardant Mepiquat Chloride 5 % AS @ 1500 ml/ha at 15 days before initiation of flowering followed by 2nd spray at initiation of flowering (T6) was found best with respect to overall plant growth, yield and quality parameters with a total yield (59.65 q/ha). Based on overall performance, it could be concluded that under prevalent climatic conditions of Uttarakhand tarai region, plant growth retardant mepiquat chloride 5 % AS @ 1500 ml/ha at 15 days before initiation of flowering followed by 2nd spray at initiation of flowering is the best in terms of higher yield of chilli cv. Pusa Jwala. Hence, recommended for commercial cultivation, provided all other scientific management practices are followed.ThesisItem Open Access Assessment of genetic variation in turmeric (Curcuma longa) germplasm(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-11) Devli, Pranjali; Singh, DhirendraThe present studies were carried out at Vegetable Research Centre (VRC) of the University, GBPUA&T, Pantnagar, Uttarakhand during kharif season of year 2020-21. Total of 38 turmeric genotypes were studied including 3 check varieties Pant Peetabh ,Sugandham and Narendra Haldi. The design of the experiment was laid out in Augmented Block Design . 38 genotypes were arranged in 7 blocks of 5 genotypes in each along with 3 check varieties. From each plot 5 plants were randomly selected and tagging was done for further observational recordings of growth yield parameters and morphological parameters. Data was compiled and it was fed to statistical analysis. Basic variability parameters like mean, range, and coefficient of variation and genetic variability parameters like PCV, GCV, heritability, genetic advance, correlation coefficient and path coefficient analysis were used for assessing the presence of variability in the experimental material. All characters were recorded PCV higher than GCV, but it is found that difference between the PCV and GCV was comparatively low for some characters suggesting characters mainly governed by genes and less affected by the environment. Heritability estimates of 9 characters ranged from 65.85% to 97.01%. Highest heritability was observed for Plant height (97.01%) and lowest for fresh rhizome yield (65.85%). Highest value of genetic advance was observed for fresh rhizome yield (146.89%) and Highest value of genetic gain was observed for number of mother rhizome (69.28%) and lowest for plant leaf lamina width (21.73%). Fresh rhizome yield showed a highly significant and positive correlation with number of leaves per plant (0.986), width of mother rhizome (0.491) and plant height (0.413). Non-significant and negative correlation was found with plant leaf lamina width and plant leaf lamina width. Number of leaves per plant (0.96573) has shown to exert highly positive direct effect on fresh rhizome yield. Characters such as plant leaf lamina length (-0.03592), plant height (-0.02249) and rhizome length (-0.02122) showed negative direct effect on fresh rhizome yield. The highest positive indirect effect on fresh rhizome yield was observed by width of mother rhizome (0.45736) which was followed by Plant height (0.38008), rhizome length (0.34555) and number of mother rhizome (0.25855) via number of leaves per plant. Based on the observations, it was concluded that in present study the important characters are plant height, number of leaves per plant, length of mother rhizome and width of mother rhizome. Genotype NYST-5 (654.16 q/ha) and NDH -35 (508.33 q/ha) found superior to check variety Pant Peetabh (452.77 q/ha), as they have superiority in these mentioned characters and such genotypes can be explored in breeding programme for further improvement of the turmeric crop. Genotypes such as NDH-129 (445.83 q/ha), Baga Haldi (441.66 q/ha) and Narendra Haldi-43 (379.16 q/ha) also showed high yield, which can be utilized in genetic improvement of rhizome yield in turmeric.ThesisItem Open Access Effect of water retainer and irrigation levels on growth, yield and water use efficiency of broccoli(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-09) Nainwal, Bhaskar; Bhatt, LalitThe present investigation was undertaken to evaluate the effect of water retainer and irrigation levels on growth, yield and water use efficiency of broccoli at Vegetable Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during rabi season in year 2019-20. Water Retainer is a water soluble liquid, which is sprayed on the surface of soil after mixing it with water, it conserves and increases soil moisture by preventing evaporation of water from the soil surface and improves water holding capacity of a soil. The experiment was laid out in randomized block design consisting of twelve treatments replicated thrice, including three doses of water retainer i.e., 1 ml, 2 ml and 3 ml per m2 applied under three irrigations levels viz. irrigation at 100, 75 and 50 percent of crop water requirement were tested along with three controls i.e., irrigation at 100, 75 and 50 percent of crop requirement. The findings of present study revealed that performance of broccoli was significantly influenced by different doses of water retainer and irrigation levels. For plant growth characters, 100 percent irrigation level with 3 ml/m2 of water retainer was best with respect to plant height, stalk length and fresh and dry weight. Maturity parameters was best in case of 75 percent irrigation with 3 ml/m2 water retainer whereas, irrigation with 50 percent of crop need along with 3 ml/m2 of water retainer was best in terms of water use efficiency (176.26 kg ha-1 mm-1). Water retainer dose of 3 ml/m2 and 100 percent irrigation was found superior in terms of getting maximum yield of 145.17 q/ha. Based on the overall performance, it could be concluded that, incorporation of water retainer at the rate of 1 ml/m2 with irrigation at 75 percent of crop requirement was observed better with respect to water use efficiency (127.81 kg ha-1 mm-1), yield (139.23 q/ha) and benefit cost ratio (3.27). Hence, recommended for commercial cultivation at farmers’ fields under water stress or rainfed situation.ThesisItem Unknown Pre-harvest application of eco-friendly chemicals and fruit bagging to enhance yield and quality of mango cv.

Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-10) Arya, Premlata; Rao, V.K.The present investigation was carried out at Model Floriculture Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar, Uttarakhand to study the influence of packaging and storage on seed quality and longevity of winter annual flowers during the year 2020-21. Five winter annual flower seeds viz. dianthus, dog flower, lupin, paper flower and verbena were packed in five packaging materials viz. cloth bag (130 gsm), plastic bag (180 gauge), aluminium bag (200 gauge), yellow paper bag (80 gsm) and glass jar (with perforated lid) immediately sealed and kept for six months of storage under ambient conditions. The experiment was laid out in factorial completely randomized design comprising of 75 treatment combinations with three replications. During the course of investigation, observations on first count germination (%), standard germination (%), seedling root length (cm), seedling shoot length (cm), seedling length (cm), seedling fresh weight (mg), seedling dry weight (mg), mean daily germination, vigour index –I, vigour index –II, speed of germination, relative growth index, mean germination time (days), t-50 value of germination, peak value were recorded. Among all treatments, lupin seed packed in plastic bag (C3P2S1) recorded highest first count germination (37.99 %, 36.03 % and 33.99 %), standard germination (85.70 % , 84.00 % and 80.00 %), seedling root length (3.50 cm, 2.89 cm and 2.41 cm), shoot length (6.69 cm, 5.80 cm and 5.57 cm ), seedling length (10.19 cm,8.69 cm and 7.98 cm), fresh weight (24.95 mg, 22.88 mg and 21.29 mg), dry weight (3.70 mg, 2.52 mg and 2020 mg), vigour index –I (872.68, 729.44 and 637.04), vigour index- II (317.09 , 2.11.68 and 176.00), peak value (8.57 , 8.39 and 7.89) whereas, lowest mean germination time (2.26 days, 2.71 days, 2.80 days) and t-50 value of germination (2.10, 2.34, 2.49 days) are recorded during storage periods i.e. initial, three months and six months respectively. Based on the above findings of present investigation, it can be concluded that packaging materials, genotypes and storage environment, all determine the storability of annual flower seeds. The plastic bags (180 gauge) and aluminium bags (200 gauge) are proved to be the best packaging materials in terms of the all the seed quality parameters for winter annual flower seeds for longer storage period at ambient conditions. The lupin and dog flower seeds proved to do well in all the germination parameters so that we can prefer as a good winter annual flowers for longer duration of time.ThesisItem Open Access Effect of drip irrigation and mulching on plant growth, flowering and fruiting in litchi cv. Rose Scented(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-09) Shankar Lal; Singh, NavinThe present study entitled “Effect of drip irrigation and mulching on plant growth, flowering and fruiting in litchi cv. Rose Scented” was carried at Horticultural Research Centre, Patharchatta, GBPUA&T, Pantnagar during the year 2021. The experiment was conducted on 21 years trees of litchi cv. Rose Scented planted at a spacing of 5m × 5m. The trial was laid out in Randomized Block Design with 3 replications and each replication comprised of two trees. The treatments consisted of four drip irrigation (DI) levels i.e., 50% ER (Evaporation Replenishment), 75% ER, 100% ER, 125% ER either with or without mulch. Flood irrigation provided in the basin of the trees was taken as control. The investigation revealed that per cent increment in all the plant growth characters like tree height, stem girth, trunk cross-sectional area, canopy spread, canopy area and canopy volume was significantly influenced with different treatments. The study also showed significant influence of drip irrigation and mulching on percentage of fruit drop, retention and cracking. Maximum number of fruits (1386.33) and yield (34.64 kg/tree and 13.86 t/ha) were witnessed under the treatment DI3M1 (100% ER with black polythene mulch) and was at par with or closely followed by DI2M1 (75% ER with black polythene mulch). In terms of fruit quality, the treatment DI2M1 recorded highest contents of total soluble solids (19.92B), ascorbic acid (24.94 mg/100g) along with lowest acidity (0.41%) while the treatment DI3M1 was found to be superior with respect to maximum fruit length (35.23 mm), breadth (32.21 mm), weight (24.98 g), volume (23.78 ml), reducing sugars (9.70 %) and total sugars (14.36%).
