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.

    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), 2019-06) Rana, Pankaj; Dimri, D.C.
    The present investigation was carried out at Horticulture Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, Udham Singh Nagar (Uttarakhand) during January, 2018 to January, 2019. The experiment was laid out in Factorial Randomized Block Design with two factors comprising of stents/cutting (China Pear stent, Baggugosha stent and Quince cutting) and five IBA concentrations (Control, 500 ppm, 1000 ppm, 1500 ppm and 2000 ppm). Thus, 15 treatment combinations were tested in three replications. The observstions in respect of days to sprouting, duration of sprouting, vegetative growth, rooting and other plant attributes were recorded. Findings of the present investigation revealed that Baggugosha stent takes the minimum days to sprouting (23.93 days) while, quince cutting showed the minimum sprouting duration (28.33 days) and maximum initial sprouting (93.67%), plant height (132.18 cm), plant thickness (14.40 mm), number of leaves (150.96), fresh weight of shoot (114.16 g), dry weight of shoot (74.66 g), root thickness (8.82 mm), number of primary root (12.92), number of secondary root (21.28), length of primary root (24.77 cm), length of secondary root (13.47 cm), fresh weight of root (63.73 g), dry weight of root (50.79 g), success percentage (66.20%) and minimum in mortality percentage (33.80%). The IBA treatment @ 1000 ppm was found to induce the earliest sprouting (24.11 days), minimum duration of sprouting (29.89 days), maximum initial sprouting (96.67%), plant height (111.07 cm), plant thickness (15.53 mm), number of leaves (127.69), fresh weight of shoot (95.07 g), dry weight of shoot (55.59 g), root thickness (9.19 mm), number of primary root (12.93), number of secondary root (20.98), length of primary root (23.10 cm), length of secondary root (12.69 cm), fresh weight of root (61.06 g), dry weight of root (47.91 g), success percentage (75.26%), while minimum in mortality percentage (25.33%). The interaction effects of stents/cutting and IBA showed the minimum number of days to sprouting under Baggugosha stent treated with 1000 ppm IBA (21.33 days) while, the minimum duration of sprouting was recorded with quince cutting treated with 1000 ppm IBA (26.00 days). The quince cutting treated with 1000 ppm IBA recorded the maximum sprouting (98.33%), plant height (144.32 cm), plant thickness (17.12 mm), number of leaves (155.33), fresh weight of shoot (123.16 g), dry weight of shoot (83.65 g), root thickness (10.12 mm), number of primary root (14.00), number of secondary root (22.80), length of primary root (26.27 cm), length of secondary root (14.74 cm), fresh weight of root (69.04 g), dry weight of root (56.17 g), success percentage (77.00%) and minimum in mortality percentage (23.00%). Results of the present investigation revealed that, quince cutting performed better than China Pear and Baggugosha stent. The China Pear and Baggugosha otherwise do not responded to propagation by simple cutting, but when grafted on to the quince cutting, it performed unexpectedly well. Therefore, on the basis of overall effects of stenting and IBA, the stenting of China Pear or Baggugosha along with the application of 1000 ppm IBA is recommended for the production of quality plants of pear on quince cutting rootstock.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-06) Gupta, Niket; Rai, Ratna
    The present study entitled “Effect of drip irrigation and mulching on plant growth, leaf nutrients status, fruit yield and quality of litchi” was carried at Horticulture Research Centre, Patharchatta, GBPUA&T, Pantnagar during the year 2017-18. The experiment was conducted on 17 years trees of litchi cv. Rose Scented planted at a spacing of 5m × 5m.The trial was laid out inRandomized Block Design with four replications and each replicationcomprised of two trees. The treatments consisted of four irrigation levels i.e., 50% ER, 75% ER, 100% ER, 125% ER either with or without mulch. Surface irrigation provided in the basin of the trees was taken as control. The investigation revealed that there was no significant effect of drip irrigation and mulch treatments on plant growth characters,however, per cent increment in all the plant growth characters liketree height, tree girth, canopy spread, canopy area and canopy volume was significant. Similarly, fruiting characters, yield and quality attributes were also significantly affected. The study also showed significant influence of drip irrigation and mulching on leaf nutrients content, percentage of fruit drop, retention,cracking and fruit burn. Maximum number of fruits and yield were witnessed under the treatment T8 (100% ER with mulch) and was at par with T7 (75% ER with mulch). In terms of fruit quality, the treatment T7 recorded highest contents of TSS, ascorbic acid along with lowest acidity while the treatment T8was found to be superior with respect to maximum fruit size, weight, volume, edible portion (per cent), reducing sugars and total sugars. It was closely followed by the treatment T7, which also registered maximum benefit cost ratio (3.98) in comparison to T8 which has benefit cost ratio of 3.33. Based on overall performance, it can be concluded that undertarai regions of Uttarakhand, drip irrigation at 75% ER along with poly mulch gives better quality fruits along with higher yield and also provides higher economic returns. Further, long terms trials are required to strengthen the above findings. Overall farmer’ scan be advised to use drip irrigation at 75% ER along with bicolourpolymulch of 100 micron for obtaining higher yield and increased water use efficiency.

    Evaluation of brinjal (Solanum melongena L.) germplasm under tarai region of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-06) Bhatt, Saurabh; Singh, Dhirendra Kumar
    An experiment entitled “Evaluation of Brinjal (Solanum melongena L.) Germplasm under Tarai Region of Uttarakhand” was undertaken during winter season of 2017-18 (September to June). Fourty-one genotypes including two checks were evaluated in Randomized Block Design with three replications at Vegetable Research Centre GBPUA&T, Pantagar. Analysis of variance revealed highly significant differences among genotypes for all the characters studied. The genotypic and phenotypic coefficients of variation were high for number of fruits per plant, average fruit weight, fruit yield per plant, total marketable fruit yield q/ha, harvest-wise yield kg/plot, fruit length, fruit diameter, reaction to fruit and shoot borer, number of secondary branches per plant and number of primary branches per plant. A narrow range of genetic difference between PCV and GCV of these traits indicates that a little influence of environment on phenotypic expression of these traits. Very high heritability along with high genetic advance as percent over mean was recorded for the characters like average fruit weight, reaction to fruit and shoot borer, number of fruits per plant, fruit length, fruit diameter, days to first harvest, total marketable fruit yield q/ha, fruit yield per plant, harvest-wise yield kg/plot, days to 50% flowering and plant height indicating direct selection for these traits would prove useful. Fruit yield per plant was found positively and significantly correlated with total marketable fruit yield q/ha, number of fruits per plant, average fruit weight and harvest-wise yield kg/plot. This indicated selection for these traits would be effective to improve the fruit yield per plant in brinjal. The higher magnitude of positive direct effect on fruit yield per plant was observed in total marketable fruit yield q/ha, number of fruits per plant, average fruit weight and harvest-wise yield kg/plot indicating their true positive and significant association with fruit yield per plant. Hence, direct selections of these traits are important for improvement of yield per plant. Fourty-one genotypes were classified into ten clusters following cluster analysis. Maximum intra-cluster distance was found in cluster IV showing existence of wide genetic divergence. Maximum inter-cluster D2 values were observed between the clusters IX and X indicating that the genotypes in these clusters can be used as parents in hybridization programme. Among the characters, reaction to fruit and shoot borer showed maximum contribution towards the diversity followed by average fruit weight, number of fruits per plant, fruit length, days to first harvest and fruit diameter. The genotypes PB-301, PB-306 and PB-307 as round fruit shape genotypes, PB-321, PB-310 and PB-319 for long fruit shape genotypes are higher yielder and the infestation of fruit and shoot borer was found minimum for PB-304 and PB-330. Based on these observations, above genotype can be recommended for cultivation under tarai region of Uttarakhand.

During the course of experiment plant height, plant spread, number of branches per plant, number of leaves per plant, days to first flower bud appearance, days to 50 per cent flowering, number of flowers per plant, flower diameter, flowering duration, fresh and dry weight of single flower, flower yield per plant, flower yield per plot, flower yield per hectare, shelf life of flower under open condition and in polythene covers, total carotenoid content and benefit cost ratio were studied. All the traits pertinent to vegetative growth, flowering and total carotenoid content were significantly influenced by marigold varieties. Highest plant height (34.00 cm), plant spread (28.13 cm) and number of leaves per plant (82.27) were found in Sakata Marigold Hybrid (Orange). Significantly maximum number of branches per plant (21.25), number of flowers per plant (100.16) and longest flowering duration (114.00 days), flower yield per plant (1947.55 g), flower yield per plot (70.11 kg) and flower yield per ha (121.72 t) and benefit cost ratio (5.05) were recorded in Arka Agni. Earliest first flower bud appearance (50.67 days) and highest single fresh flower weight (27.11 g) were found in Indo-American Hybrid Marigold whereas, dry weight of single flower was highest in the Sakata Marigold Hybrid (Gold) (2.68 g). Days to 50 per cent flowering i.e. 88.67 days and higher total carotenoid content (523.05mg/100g) were recorded in the Pusa Narangi Gainda. Flower diameter was maximum (9.90 cm) in variety Sakata Marigold Hybrid (Yellow). Shelf life of flower under open condition (6.67 days) and in polythene (10.67 days) was observed highest in variety Arka Bangara. On the basis of the findings of present study, this may be concluded that variety Arka Agni is most suitable for commercial cultivation of African marigold for obtaining a remunerative loose flowers yield whereas, variety Pusa Narangi Gainda can be for carotenoid content under tarai region of Uttarakhand.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-06) Raj Kiran; Singh, Navin
    The present investigation “Effect of different containers and wrappers on physicochemical parameters for shelf life of guava (Psidium guajava L.) cv. Sardar” was conducted in the postharvest Laboratory, Department of Horticulture, College of Agriculture, G.B. Pant University of Agriculture and Technology, Pantnagar, to find out the suitable post harvest treatment combinations on storage and to extent the shelf life of guava. The experiment was laid out in two factorial completely randomized design with 13 treatment combinations including control and 3 replications. An experiment was carried out at an ambient storage condition during winter season. The physico-chemical changes were recorded under each treatment from harvesting till 12th day of storage in winter seasons. Physical parameters viz., fruit length, breadth, volume and weight exhibited decreasing trend with advancement of storage period but different packaging methods slow down the rate of decrease in comparison with control. Lesser reduction in these parameters was found in fruits kept in CFB box after wrapping with tissue paper as compared with higher reduction in controls. Fruits kept in corrugated fiber box after wrapping with tissue paper (C1W1) was most effective in reducing weight loss and decay than other treatments. Quality parameters viz., total soluble solids, total sugars, reducing sugars and ascorbic acid of fruits were recorded higher in CFB box and tissue paper among containers and wrappers, respectively.Total soluble solids, total sugars, reducing sugars and non reducing sugars gradually increased upto 6th days and then slightly decrease with the advancement of storage duration whereas titratable acidity and ascorbic acid contents gradually decreased significantly with the advancement of storage duration. On the basis of result obtained it can be concluded that fruits were packed in CFB box after wrapping with tissue paper proved best for maintaining shelf life and quality of guava fruits.
