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.

    (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.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-01) Bhatt, Siddharth Shankar; Dimri, D.C.
    The present investigation was carried out at Horticulture Research Centre, Patharchatta, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, District-Udham Singh Nagar, Uttarakhand in the year January- July, 2015 and 2016. The experiment was conducted on 8 years old healthy fruit bearing trees of plum cultivar ‘Kala Amritsari’ having uniform size and vigor. Investigation was laid out in Randomized Block Design (RBD) with three replications and 16 treatments namely; GA3 (25 ppm), GA3 (50 ppm), GA3 (75 ppm), NAA (25 ppm), NAA (50 ppm), NAA (75 ppm), BA (25 ppm), BA (50 ppm), BA (75 ppm), ethephon (100 ppm), ethephon (150 ppm), ethephon (200 ppm), ATS (1.0%), ATS (1.5%), ATS (2.0%)and control (water spray).Observations were recorded on plant growth, flowering, fruit set, fruit physico-chemical and plant physiological parameters. Findings of the present investigation revealed that ATS @ 1.5% recorded maximum extension of shoot growth (32.61 cm), highest number of leaves (34.25) and maximum size of leaves (12.36 cm2) while, highest number of damaged leaves was observed under ATS @ 2.0 % (8.30). In respect to flowering and fruit set parameters the treatment control recorded highest bloom density (50.66%), number of flowers retained (43.36) and number of flower per cluster (8.03). Ethephon @ 150 ppm (80.73 days) however, took least number of days to maturity. The highest initial fruit set (43.70%) though was calculated under the control treatment but maximum fruit retention (34.39%) was counted for ATS @ 1.5% with least fruit drop (65.61%) resulting in highest yield per tree (34.14 kg). Application of the treatment ATS @ 1.5% was found superior among all blossom thinners in enhancing maximum fruit length (4.14 cm), highest fruit width (3.06 cm), maximum fruit weight (21.53 g) and highest fruit volume (22.10 ml). The highest pulp weight (21.35 g) and least stone weight (0.84 g) was also measured under ATS @ 1.5% which as a result calculated highest pulp: stone ratio (27.94). Among different chemical blossom thinners sprayed maximum total soluble solids (12.64), least titrable acidity (0.58), highest ascorbic acid (9.11 mg), maximum total sugar (6.29%) and highest total carotenoides content (10.87 mg) was estimated when ATS @ 1.5% was applied at post bloom stage. Plant physiological parameters was also affected with ATS @ 1.5% which calculated least Chlorophyll ‘a’ content (1.54 mg) and Chlorophyll ‘b’ content (0.88 mg). Based on the present investigation it can be concluded that ATS @ 1.5% was found to be most effective blossom thinner in enhancing plant growth, yield and physico-chemical attributes in plum cv. ‘Kala Amritsari’ under tarai region of Uttrakhand.

    Optimization of coating formulations and packaging conditions for shelf life enhancement of litchi (Litchi chinensis Sonn.) under different storage conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-03) Sunil Mohan, Jogdand; Lal, R.L.
    The exploration of the new nutrition based sources of the edible coatings and their commercial utilization is one of the prominent step to meet the peculiar demand of litchi fruits to explore its marketing throughout country. There are several coating materials available, but their low efficiency and particular action is the major barrier to coating of litchi fruits to prevent pericarp browning. The use of combine formulations containing nutrition supplement is an important emerging technique of coating having potential to overcome the limitations of conventional methods of coatings. The present investigation aims to develop an efficient and specific coating formula and to standardize perforation levels of packaging for low density polyethylene, to prevent pericarp browning during both cold and ambient storage, with maintenance of health promoting substances. The bio based coating materials were selected for the coating and low density polyethylene for packaging. The present research has been undertaken to standardize and optimize the coating formulation and packaging perforation to prevent pericarp browning and maintain health promoting substances during cold and ambient storage. Through the preliminary experiments, the levels of the _-Tocopherol, chitosan, salicylic acid and perforation percentage were decided. Four independent variables having five levels of each i.e. LD _- Tocopherol (0.1, 0.2, 0.3, 0.4 and 0.5 %), chitosan (0.5, 1.0, 1.5, 2.0 and 2.5 %), salicylic acid (0.5, 1.0, 1.5, 2.0 and 2.5 mM) and packaging perforation (0.1, 0.2, 0.3, 0.4 and 0.5 %) were selected as independent parameters. Optimization of the independent variables was done based on physiological loss in weight, firmness, pericarp browning, total soluble solids, titratable acidity, ascorbic acid content, total sugar, Anthocyanin content, Total phenolics content, Total flavonoids content, Total antioxidant capacity, PPO activity and POD activity. Multiple response optimization of independent parameters was done using Design Expert 8.0.6. Study revealed that there was decrease in physiological loss in weight, firmness, pericarp browning, polyphenol oxidase and peroxidase activity with increase in _-Tocopherol as well as chitosan. The optimized combination of independent variables was found to be 0.4% _-Tocopherol, 2.0 chitosan, 2.0mM salicylic acid and 0.4% perforation percentage. At optimized condition, maximum shelf life of litchi were recorded with higher nutritional and health promoting substances in both ambient and cold storage conditions. The physiological loss in weight for ambient storage condition (5.23 to 8.81 %). Whereas it was in the range of 3.31 to 5.74 % under cold storage condition. Firmness of coated litchi fruits was in between for ambient 15.52 to 21.47 N and 15.51 to 21.89 N cold storage. The pericarp browning index (52.7 to 208.55), while it was significantly lower in cold storage 18.96 to 73.91. Acidity was in the range of 0.12 to 0.27 %, whereas at cold storage condition in the range 0.26 to 0.38 %. The ascorbic acid content varied in the range of 6.97 to 20.57 mg/100g FW for ambient storage condition and (15.38 to 24.31 mg/100g FW) under cold storage condition. The total sugars varied from 10.26 to 13.29 %. At the same time under cold storage it was13.54 to 16.29%. The anthocyanin content was 2.87 to 8.94 mg/100g and 8.26 to 14.68 mg/100g respectively for ambient and cold storage condition. The significant difference amongst the treatments and storage conditions were recorded in total phenolic content (99.45 to 394.56 μg GAE/g FW) and under cold storage (361.28 to 796.75 μg GAE/g FW). The total flavonoids content were decreased continuously under ambient storage from 1.43 to 9.87 μg CE/g FW, while it was 8.36 to 16.87 μg CE/g FW for cold storage condition. Antioxidant capacity of coated litchi fruits stored at ambient storage condition varied in the range of 0.126 to 0.322 (ABTS assay) μmol TE/ g FW, whereas the range was 1.13 to 2.92 (ABTS assay) μmol TE/ g FW for cold storage. The radical scavenging activity in litchi was (16.71% to 35.75 %) and (29.76 % to 47.96 %) for ambient and cold storage conditions respectively. The polyphenol oxidase activity(5.23 to 9.95 U/μg Protein) and peroxidase activity 7.45 to 13.95 (U/μg protein) under ambient condition further it reduces 3.19 to 6.69 (U/μg Protein) and 5.35 to 9.72 (U/μg protein) under cold storage conditions respectively. Significant effect of all the independent parameters was observed on the all responses except total soluble solids at its linear level while no any significant effect was found at interactive level.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-01) Singh, Neeraj; Singh, Dhirendra Kumar
    The present investigation was carried out during rainy season (2015) and warm season (2016 and 2017) at Vegetable Research Center of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, with the objectives to assess genetic variability, inter-character association and their direct and indirect effects, heterosis, combining ability and gene action for different quantitative traits. Genetic variability, inter-character association and path coefficient analysis were studied in 185 okra genotypes. The analysis of variance revealed significant genetic differences were present among okra genotypes for the fifteen characters under study. A moderate to wide range of mean values among the genotypes for different characters were observed. Moderate to high genotypic coefficient of variation together with moderate to high heritability and genetic advance as per cent of mean was reported for majority of the characters under study except average fruit weight which indicated predominant additive gene action thus these traits has an ample scope for the improvement of concerned traits through selection. The association analysis showed, highly significant and positive correlation of fruit yield per plant with number of fruits per plant followed by plant height, average fruit weight, number of seeds per fruit, fruit length, days to 50 per cent flowering, first fruit producing node, stem diameter and first flower producing node respectively, indicating the possibility of simultaneous selection among these traits. Path coefficient analysis revealed that fruit width followed by number of fruits per plant, first fruit producing node and average fruit weight had had maximum direct and indirect contribution on fruit yield per plant. Two genotypes viz., EC169430 and EC169435 were showed highly resistance reaction against yellow vein mosaic virus. Further, based on evaluation for yellow vein mosaic virus resistance, yield and earliness, fifteen genetically diverse genotypes were selected for estimation of heterosis and combining ability. From these fifteen genetically diverse parents, thirty six crosses were evolved in a line × tester mating design with twelve genotypes as female parents (lines) and three genotypes as male parents (testers). Based on extent of heterosis, EC169400 × Arka Anamika and IC117351 × Arka Anamika was identified as most promising cross combinations in among 36 crosses for many traits viz., fruit yield per plant, number of fruits per plant, plant height and inter-nodal length. The per se performance of these crosses was also superior over other crosses studied hence these crosses could be utilized as commercial hybrids. EC169400 was identified as consistent best general combiner for four traits viz., fruit length, plant height, number of fruits per plant and fruit yield per plant. For earliness character (days to 50 per cent flowering) IC093655, IC117123 and EC169430 were identified as consistent good general combiner during both the year. Ranking of desirable parents based on per se performance, gca and sca effects for 14 characters revealed that it was difficult to pick up a single good combiner for all the characters. Over the both years consistently, cross combinations viz., IC117245 × VRO 6 for fruit yield per plant, IC117245 × VRO 6, IC117351 × Arka Anamika and EC16400 × Arka Anamika for number of fruits per plant, EC169430 × Parbhani Kranti and EC169408 × Arka Anamika for plant height, EC169435 × Parbhani Kranti for 100 seed weight, IC093655 × Arka Anamika for number of seeds per fruit, EC169430 × Parbhani Kranti for primary branches per plant, IC093655 × Parbhani Kranti for intermodal length, EC169435 × Arka Anamika for fruit length showed specific combining ability effects of higher order. The estimates of _2 gca / _2 sca indicated predominance of non-additive gene action for most of the characters during both the years.

    Studies on combining ability, molecular diversity and response to late blight (Phytophthora infestans (Mont.) de Bary) in tomato (Solanum lycopersicum L.) under polyhouse condition
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Panchbhaiya, Ankit; Singh, Dinesh Kumar
    The present investigation was carried out at Vegetable Research Center of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, with the objectives to assess the genetic variability, molecular diversity, heterosis, combining ability, gene action, screening for late blight disease and estimation of percentage fruits damage due to Tuta absoluta in tomato. The analysis of variance for RBD and combining ability revealed significant genetic differences among 36 tomato genotypes for the fifteen yield related and ten quality traits under study. The magnitudes of PCV estimates were higher than the corresponding GCV estimates for all the characters. Moderate to high GCV together with moderate to high heritability and genetic advance as per cent of mean was reported for majority of the characters under study except characters related to earliness viz., days to 50 per cent flowering, day to first fruit set and days to fruit ripening. A total of 20 SSR markers tested out of which 16 were polymorphic and 4 markers had shown monomorphic on agarose gel. Among eight genotypes of tomato total number of 46 bands exhibited by these 16 SSR primers and among them 43 was polymorphic and 3 were monomorphic. The range of amplified products was 100-700bp approximately and number of alleles per locus varied from two to six. Average number of bands per primer was 2.86. A range of polymorphism was observed from 50 per cent to 100 per cent with an average of 93.23 per cent. The PIC value ranged from 0.117 to 0.891 with an average 0.596. Jaccard’s similarity coefficient varied from 0.52 to 0.94 with an average value of 0.70. PBT-9 and PBT-13 (0.94) were found to be the most similar genotypes among the eight genotypes studied followed by PBT-10 and PBT-13 (0.90). Minimum Jaccard’s similarity coefficient was found in PCT-1 with PBT-2 and PBT-5 (0.52). The clustering pattern obtained by SSR primer showed that PCT-1 (cherry tomato line) and PBT-4 (potato leaf type) showed deviation from existing cluster. Hybrids, PCT-1 x PBT-5, PBT-9 x PBT-5, PBT-9 x PBT-2 and PBT-2 x PBT-13 were found promising for earliness while, for fruit yield, PCT-1 x PBT-5, PBT-2 x PBT-13, PBT-9 x PBT-4 and PBT-5 x PBT-4 were found promising hybrids. For most of the fruit quality traits promising hybrids were PCT PCT-1 x PPT-2, PBT-9 x PBT-2, PBT-2 x PBT-4 and PPT-2 x PBT-10, hence these crosses could be utilized as commercial hybrids for earliness, high yielding and industrial processing, respectively. PCT-1 was identified as a best general combiner for maximum number of yield related and fruit quality traits followed by PPT-2 and PBT-5. The best specific combiner were PBT-2 x PBT- 13 followed by PBT-13 x PBT-10, PBT-9 x PBT-5, PCT-1 x PBT-5 and PBT-9 x PBT-4 for most of the yield related and fruit quality traits studied. Among all yield related and fruit quality traits most of the characters were under the control of non additive gene action with over or partial dominance effect except fruit firmness, hence these characters are suitable for hybrid breeding. For late blight disease resistant reaction, out of all F1 hybrids six cross combinations showed resistant and thirteen hybrids showed moderately resistance reaction. Among 28 hybrids, minimum average percentage fruits damage due to Tuta absoluta was found in PCT-1, PCT-1 x PBT-5 and PCT-1 x PBT-13.

    Biochemical and molecular characterization of diverse genotypes of bael (Aegle marmelos Correa.) for their nutraceutical properties
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Kholia, Anjana; Misra, K.K.
    The investigation entitled “Biochemical and molecular characterization of diverse genotypes of Bael (Aegle marmelos Correa.) for their nutraceutical properties” was carried out on 24 diverse genotypes of Bael at G. B. Pant University of Agriculture & Technology, Pantnagar, U. S. Nagar, Uttarakhand, during the year 2016-18. Out of the 24 genotype , the 18 genotypes of Bael were characterized on the basis of biochemical parameters i.e., ascorbic acid, marmelosin, total phenol content, pectin content, riboflavin, total carotenoids, total falvonoids, enzymatic antioxidants, DPPH radical scavenging activity, total soluble sugar, phenylalanine ammonia lyase and polyphenol oxidase enzyme activity. The biochemical analysis revealed that Pant Bael-1, Pant Sujata, Pant Bael-3, Pant Shivani and Pant Aparna were found suitable for future breeding programme as they had more than one desirable biochemical character. The 24 genotypes of Bael were characterized on the basis of SSR marker based polymorphism. The UPGMA dendrogram based on genetic distance, segregated the 24 Bael genotypes into two major clusters. The major cluster A consist of 19 genotypes, which was further divided into two sub clusters IA and IIA at 66 per cent similarity. The major cluster B consist of 5 genotypes, which was further divided into two sub cluster IB and IIB at 78 per cent similarity. The polymorphic Information Content (PIC) values ranged from 0.234-0.998. Jaccard’s similarity coefficient values ranged from0.271 to 0.951with polymorphism of 100 per cent. A total of 59 loci were detected with amplified size range of 100 to 800 bp. The maximum numbers of loci (5) were detected by the primer CAC33. The 11 genotypes of Bael with 66 treatment combination were used to develop the nutraceuticaly rich appetizer. The quality analysis was done on the basis of total sugar, reducing sugar, non reducing sugar, titratable acidity, ascorbic acid, moisture and non enzymatic browning of appetizer. The sensory evaluation of appetizer was done based on different sensory parameters i.e., colour, flavour, taste, texture and over all acceptability. The highest score obtained for different sensory parameters was 9 (Like extremely) and the lowest score was 5 (Neither like or nor dislike). The significant variation exist among the genotypes based on biochemical characters but with the use of SSR markers, assessment of the genetic diversity can also help us to lan a future breeding programme using the diverse parent. The nutraceutically rich appetizers were developed involving different Bael genotypes and ingredients.
