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.

    Effect of silicon dioxide nanoparticles on micropropagation and metabolomics of strawberry (Fragaria × ananassa duch.)
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-03) Pradyot, Nalini; Rai, Ratna
    Microbial contamination and oxidative stress induced damage are the two most limiting factors in micropropagation, which not only reduce the plantlet quality but also affect the survival rate during acclimatization. Nanoparticles (NPs) due to their unique properties exhibit broad spectrum antimicrobial activity against pathogens and also enhance the growth and development of plants by assisting in protection against abiotic stresses. The present investigation was carried out at G.B.P.U.A. & T., Pantnagar, during the year 2017-21, to study the various effects of SiO2 NPs on micropropagation of strawberry cv. Chandler. For explant sterilization, different concentrations of SiO2 NPs (50-1000 ppm) were either used through priming or directly inoculated in the MS medium. For growth studies, explants were multiplied in MS media supplemented with various concentrations of SiO2 NPs (50-200 ppm) along with PGRs. The results showed that lowest contaminate rate was observed in explants inoculated in MS medium containing SiO₂ NPs @ 200 ppm. Highest number and length of shootlets, highest number of roots, maximum shoot and root biomass and 100 per cent survival rate of plantlets during acclimatization was observed in plantlets obtained from 150 ppm SiO2 NPs incorporated growth medium. Improved RWC and enhanced production of chlorophyll, carotenoids, proline and antioxidant enzymes such as SOD, CAT, GPX, APX and GR activity was also observed in plantlets cultured in 150 ppm SiO2 NPs containing growth medium as compared to control. It was also evident from the metabolomics data, that plantlets obtained from 150 ppm SiO2 NPs media showed an increase in various sugars, amino acids and organic acids concentration as compared tocontrol during different developmental stages. Thus, it can be concluded that SiO2 NPs was highly effective in controlling contamination and enhanced the efficiency of micropropagation by reducing the cost of in vitro cultures and improving stress tolerance in plantlets as compared to conventional micropropagation methods.

    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.

    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.D
    The 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.
