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.

    Evaluation of brinjal (Solanum melongena L.) germplasm under organic conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-06) Bisht, Yashpal Singh; Verma, Alka
    An experiment on “Evaluation of Brinjal (Solanum melongena L.) Germplasm Under Organic Conditions” was undertaken during kharif season of 2017. Forty-seven genotypes including two checks were evaluated in RBD with three replications in Vegetable Research Centre GBPUA&T, Pantnagar. Analysis of variance revealed highly significant differences among genotypes for all the characters studied. The genotypic and phenotypic coefficients of variation were high for fruit length, fruit diameter, number of fruits per plant, average fruit weight, marketable yield per plant, yield per plant and total yield per hectare. 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 fruit length, fruit diameter, number of fruit per plant, average fruit weight, marketable yield per plant, incidence of fruit and shoot borer per plant and total yield per plant indicating direct selection for these traits would prove useful. Yield per plant was found positively and significantly correlated with fruit length, number of fruits per plant and marketable yield per plant. This indicated selection for these traits would be effective to improve the yield per plant in brinjal. The higher magnitude of positive direct effect on yield per plant was observed in marketable yield per plant, number of primary branches and fruit diameter indicating their true positive and significant association with yield per plant. Hence, direct selections of these traits are important for improvement of yield per plant. Forty-seven genotypes were classified into seven clusters following cluster analysis. Maximum intra-cluster distance was found in cluster II showing existence of wide genetic divergence. Maximum inter-cluster D2 values were observed between the clusters I and II indicating that the genotypes in these clusters can be used as parents in hybridization programme. Among the characters, number of fruits per plants showed maximum contribution towards the diversity followed by fruit length, marketable yield per plant, incidence of fruit and shoots borer, fruit diameter and average fruit weight. The genotypes Pusa Kaushal, Pusa Purple Cluster and Pusa Anupum as long fruit shape genotypes, Pusa Ankur for round fruit shape genotypes are higher yielder and the infestation of fruit and shoot borer was found minimum for Pusa Purple Cluster and DBL-02. Based on these observations, above genotype can be recommended for cultivation under organic conditions.

    Mutation breeding for leaf thrips resistance in cowpea (Vigna unguiculata (L.) Walp)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-06) Negi, Tribhuwan Singh; Singh, Y.V.
    The present investigation was conducted to induce genetic variability in six cowpea cultivars viz. PL-1, PL-2, PL-3, PL-4, PL-5 and PGCP-28 and to isolate leaf thrips resistant mutants which can be used as such as new varieties or as parents in hybridization programme for developing superior varieties. The seeds of the six cowpea varieties were exposed to 25 kR (250 Gy) doses of Co 60 gamma radiations at Bhabha Atomic Research Centre, Trombay, Mumbai. The experiment was undertaken during kharif Season, 2016, zaid season, 2017, kharif season, 2017 and zaid season, 2018 at Breeder Seed Production Centre (BSPC), Govind Ballabh Pant University of Agriculture & Technology, Pantnagar, Udham Singh Nagar, Uttarakhand. The effect of gamma rays treatment on the per cent seed germination was studied in M1 generation and results indicated that the gamma rays had an inhibitory effect on the per cent seed germination of cowpea. In M2 generation, the plants were screened for desirable traits like tallness/dwarfness, earliness, pod per plant and leaf thrips resistance. In PGCP-28, 47 resistant and 112 moderately resistant plants were identified accounting for 6.41% and 15.27% of mutation respectively. The seed mutants were also isolated having black, dark brown and dark red seed coat colour. In M3 generation, various desirable mutants for yield traits were isolated having high number of pods per plant ranging from 57 to 65. Pod mutants having curved and upright pods and black seed coat mutants were also observed in M3 generation. During M4 generation, leaf thrips resistant and moderately resistant mutant were identified in PL-5 and PGCP-28. The numbers of leaf thrips resistant mutant in PL-5 and PGCP-28 was 68 and 28 respectively. Various other mutants like sterile and partial sterile mutants were also observed from M1 to M3 generation having sterile and partial sterile pollens. Thus, there was increase in the variability for different characters. Several desirable mutants were isolated having early maturity, vigorous plants growth, long pod length, high number of pods per plant and resistant to leaf thrips which can be exploited in cowpea improvement programme especially breeding for leaf thrips resistance. Mutant having upright pods with long peduncle can be advanced to develop plant types that are suitable for mechanical harvesting. Thus, mutation breeding can be effectively used for cowpea improvement particularly breeding for biotic stresses.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-06) Tribhuwan Pratap; Rai, P.N.
    The present investigation was carried out at Horticultural Research Centre, Pattharchatta and College of Basic Science and Humanities, G.B. Pant University of Agriculture and Technology, Pantnagar to find out the Influence of plant growth promoting bioinoculants on the root development and plant growth of citrus species during July, 2017 to January, 2018. Plant growth-promoting rhizobacteria (PGPR) is leading bioinoculants in the initiation of root through releasing phytohormones in the rhizosphere particularly auxin. Keeping the fact in mind the present work was carried out with the involvement of these bioinoculants in air layers of citrus species. Uniform thickness and length of shoot were selected for preparation of air layers on citrus species. Different Bioinoculants such as Pseudomonas species + Ochrobactrum anthropi (DPC12+DPC9) and Pseudomonas fluorescens + Pseudomonas palluonia (DPB15+DPB16) were mixed separately with sphagnum mass grass for preparation of air layers of citrus species. In this experiment, fresh air layers were planted in polybag after detachment from mother tree. The observation i.e., root initiation, root and shoot growth characteristics, survivability and establishment and total biomass were recorded and compared with non-inoculated air layers of citrus species. The air layers treated with bioinoculants showed significant number, length, fresh as well as dry weight of root and survivability of air layers on mother trees. Therefore, on the basis of overall response of bioinoculants, it can be concluded that bioinoculants have positive effects on all aspects of growth and development of air layers of citrus species. Bioinoculants Pseudomonas species + Ochrobactrum anthropi (DPC12+DPC9) was found to be the best treatment in all the aspect of growth and development of air layers of citrus species

    The present experiment was carried out at Horticulture Research Centre, Patharachatta, G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of foliar application of calcium and boron on plant growth, yield and fruit quality of jackfruit. Experiment was conducted in Randomized Block Design with ten treatments and three replications comprising nutrients which were sprayed individually or in combination with each other viz., T1 : Calcium carbonate 0.2%, T2 : Calcium carbonate 0.4%, T3 : Calcium carbonate 0.6%, T4 : Borax 0.4%, T5 : Borax 0.6%, T6 : Borax 0.8%, T7 : Calcium carbonate 0.2%+ borax 0.4%, T8 : Calcium carbonate 0.4%+ borax 0.6%, T9 : Calcium carbonate 0.6% + borax 0.8%, T10 : Control. Treatments were applied three times as foliar spray at monthly interval starting from the initiation of flowering. The result of study revealed that treatment T9 (calcium carbonate 0.6% + borax 0.8%) significantly influence growth characters like increase in plant height, canopy spread, stem girth, tree volume, CSTA. Reproductive characters like male flower per tree, female flower per tree, total flowers per tree, number of fruit set per tree, per cent fruit set had highest value under treatment T9. Highest fruit yield per tree was obtained in treatment T9. All the physical characters of jackfruit i.e. Average fruit weight, pulp weight, rind weight, fruit length and fruit width were recorded highest with the treatment T9. With respect to quality parameters i.e. TSS, titratable acidity, TSS/acid, total sugar, reducing sugar, non reducing sugar, sugar/acid, ascorbic acid, vitamin A were highest in treatment T9. On the bases of above study it can be concluded that there was significant variation in tree growth (in terms of plant height, canopy spread, stem girth etc) yield contributing traits (number of flowers, fruit set, fruit weight, fruit size etc) along with good yield and fruit quality. Jackfruit tree should be sprayed thrice with calcium carbonate 0.6% +borax 0.8% at monthly interval starting from initiation of flowering.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-05) Rawat, Sheetal; 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, 2017 to January, 2018. The experiment was laid out in Factorial Randomized Block Design with two factors comprising of five stents/cuttings (Kala Amritsari stents, Satluj Purple stents, Kabuli Green Gauge cuttings, Kala Amritsari cuttings, Satluj Purple cuttings) and four IBA concentrations (Control, 500 ppm, 1000 ppm and 1500 ppm). Thus, 20 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 Kala Amritsari cuttings takes the minimum days to sprouting (16.67 days) while, Kabuli Green Gauge cuttings showed the minimum sprouting duration (21.25 days) and maximum sprouting (92.50%) the Kala Amritsari stents were estimated to be highest in terms of plant height (111.38 cm), plant thickness (12.84 mm), number of leaves (151.05), fresh weight of shoot (103.83 g), dry weight of shoot (54.38 g), root thickness (6.02 mm), number of primary root (13.12), number of secondary root (22.51), length of primary root (27.51 cm), length of secondary root (13.01 cm), fresh weight of root (73.50 g), dry weight of root (42.08 g), success percentage (66.67%) and minimum in mortality percentage (33.33%). The IBA treatment @ 1000 ppm was found to induce the earliest sprouting (22.40 days), minimum duration of sprouting (26.93 days), maximum sprouting (94%), plant height (102.67 cm), plant thickness (10.34 mm), number of leaves (136.80), fresh weight of shoot (92.10 g), dry weight of shoot (46.62 g), root thickness (5.56 mm), number of primary root (11.68), number of secondary root (21.42), length of primary root (26.63 cm), length of secondary root (12.13 cm), fresh weight of root (62.95 g), dry weight of root (34.32 g), success percentage (77.50%) and minimum in mortality percentage (22.50%). The interaction effects of stents/cuttings and IBA showed that the minimum number of days to sprouting under Kala Amritsari cuttings treated with 1000 ppm IBA (15 days) while, the minimum duration of sprouting was recorded with Kabuli Green Gauge cuttings treated with 1000 ppm IBA (18.67 days). The Kala Amritsari stents treated with 1000 ppm IBA recorded the maximum sprouting (96.67%), plant height (118.10 cm), number of leaves (172.33), fresh weight of shoot (115.23 g), dry weight of shoot (60.20 g), root thickness (7.29 mm), number of primary root (14.80), number of secondary root (24.57), length of primary root (29.82 cm), length of secondary root (15.32 cm), fresh weight of root (84.97 g), dry weight of root (47.90 g), success percentage (85.00%) and minimum in mortality percentage (15.62%). However, Kala Amritsari stents treated with 500 ppm showed, the maximum plant thickness (14.57 mm). Thus, it can be concluded that stenting perform better than the cuttings with respect to the overall growth and success of stenting. Therefore, the stenting of cuttings viz., Kala Amritsari (KGG+KA) stents along with application of 1000 ppm IBA is recommended for the production of quality plants of plum.

The experiment was laid out in Factorial Randomized Block Design with two factors comprising of four canopy heights (1.25 m (H1), 1.5 m (H2), 1.75 m (H3) and unpruned (H0) as control) and three planting densities (planting densities of 5000 plants/ha spaced at 2m×1m (D1), planting densities of 3333 plants/ha spaced at 2m×1.5m (D2), planting densities of 4444 plants/ha spaced at 1.5m×1.5m (D3). Thus, 12 treatment combinations were tested in four replications with one plant taken per replication. The observations in respect of vegetative growth, reproductive parameters, physical and chemical attributes, post quality quality attributes and nutrient content of guava fruit were carried out. Findings of the present investigation revealed that vegeatative growth in terms of tree volume, stem girth, number of shoots, length and width ratio of leaves, fresh weight and dry weght of the leaves was found maximum at canopy height H3 (1.75 m) in rainy season whereas in winter season tree volume and number of shoots were recorded maximum at canopy height H1 (1.25 m) and stem girth, length, width, fresh weight and dry weight of leaves was found maximum at control. Induction of flower after pruning, initial number of fruit set, fruit set per cent, fruit retained on tree before harvest, fruit yield per tree and fruit yield per hectare was found maximum with lowest fruit dop per cent at control in rainy season while in winter season these parameters was found superior at treatment H1 (1.25 m). Physical parameters like fruit length,diameter,weight, volume, pulp weight, seed weight,seed index. seed cavity size and chemical attributes like total soluable solid, total sugar per cent (reducing sugar+ non-reducing sugar), ascorbic acid and pectin content was found maximum with minimum titratable acidity at canopy height H3 (1.75 m) in rainy season while in winter season these attributes found superior at treatment H1 (1.25 m). Among planting densities, D2 (planting densities of 3333 plants/ha spaced at 2 ×1.5 m) recorded maximum in all those including vegetative, reproductive, yield, physical and chemical attributes of fruits during both the seasons. Superior in post harvest quality characters with less physiological loss in weight, loss in volume, spoilage per cent, total soluble sugar content, ascorbic acid content and shelf life was recorded at canopy height H3 (1.75 m) in rainy season while in winter season, H1 (1.25 m) registered mximum in these attributes. Keeping in view, nutrient status of fruits in terms of macro nutrients like N2, P, K and micro nutrients like Zn, Cu, Fe and Mn was attributed their maximum at canopy height H3 (1.75 m) during rainy and in winter season at canopy height H1 (1.25 m). Among planting densities, D2 (planting densities of 3333 plants/ha spaced at 2 ×1.5 m) registered superior in post harvest quality attributes and nutrient attributes of guava fruit while minimum was recorded at treatment D3 (planting densities of 4444 plants/ha spaced at 1.5 m ×1.5 m). Among treatment combinations, H3D2 (1.75 m and planting densities of 3333 plants/ha spaced at 2m ×1.5m) recorded superior in rainy season for quality attributes while treatment combination H1D2 (1.25 m and planting densities of 3333 plants/ha spaced at 2m ×1.5m) attributes superior in winter season.
