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), 2019-08) Rathor, Prerna; Sharma, A.P.
    The present study was designed to evaluate the physico-chemical factors and their effect on primary productivity in fish ponds. The experiment was conducted in three ponds viz. duckhouse pond and broodstock pond and nursery pond; having area of 0.1 ha, 0.2 ha and 0.05 ha, respectively which were situated at coordinates 28o58’N, 79o25’ E and at an altitude of 252 m above mean sea level, in Uttarakhand. Three sites in all the three experimental ponds viz. duckhouse pond (S1, S2 and S3), broodstock pond (S1', S2' and S3') and nursery pond (S1'', S2'' and S3'') were randomly selected and sampling was done fortnightly for the duration of six months i.e. from December-18 to May-19. In physical parameters water temperature, water transparency, electrical conductivity and total dissolved solids were found in the range of 15.9 to 32.5 oC, 28.0 to 54.8 cm, 201.0 to 587.0 μScm-1, and 138.5 to 424.5 mgL-1, respectively. In chemical parameters pH, total alkalinity, dissolved oxygen, free carbon dioxide, nitratenitrogen, phosphate-phosphorus, ammonia-nitrogen and silicate were recorded in the range of 7.6 to 8.4, 114.3 to 177.3 mgL-1, 4.9 to 8.5 mgL-1, 0 to 2 mgL-1, 0.32 to 0.51 mgL-1, 0.018 to 0.057 mgL-1, 0.09 to 0.35 mgL-1 and 2.56 to 5.09 mgL-1, respectively. The mean values of GPP, NPP and CR in experimental ponds were in the range of 2701.44 to 9506.88 mgCm-3d-1, 1287.36 to 4042.56 mgCm-3d-1 and 972.00 to 7874.88 mgCm-3d-1, respectively. The net production efficiency and chlorophyll a concentration in the study ponds was recorded in the range of 10.3 to 31.7% and 1.12 to 9.12 mgm-3, respectively. Phytoplankton composition of the experimental ponds consisted a total number of 24 different taxa belonging to 4 different classes namely Bacillariophyceae (12), Chlorophyceae (6), Cyanophyceae (4) and Euglenophyceae (2). The phytoplankton density ranged from 19350 to 69170 cellsL-1. Group wise distribution of phytoplankton density revealed that Bacillariophyceae was most dominant group in the experimental ponds. The maximum diversity was found in the month of May followed by April and December.

    Dynamics of area, production and export of grapes in India
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-06) Thorat, Vishal Shankar; Bhogal, T.S.
    Grape is one of the most important fruit crops of the world and contains many of the valuable ingredients necessary for life. It is also one of the important horticultural crops grown in India. Exports are must for economic growth of any country. The grape export from India was started in the year 1991 after economic liberalization. Total area under grape in India is 63700 ha. with production of 1667.7 thousand tonnes and export of about 85897.78 tonnes (5.15 per cent of total production) in the year 2006-07. Maharashtra, Karnataka, Tamilnadu and Andhra Pradesh are major grape producing states. The total area under grape in the world is around 75 lakh ha. with a production of 66.27 million tonnes (2006-07). Major grape exporting countries are Chile, South Africa, Spain, Italy, France etc. The present study was undertaken primarily to analyze India‟s performance in production, productivity and export of grapes with different dynamics. Growth rates in relation to area, production, yield and export of grapes were measured by using exponential function. Direction of grape export was analyzed by calculating the share of Indian grapes in the import of major grape importing countries of the world vis a vis share of other grape exporting countries. Export competitiveness of grape for the country has been assessed by using Nominal Protection Coefficient (NPC). Garrett‟s ranking technique was used to study the problems faced by grape growers in production and marketing as well as that of by exporters in grape export. The results of the study showed that area, production and yield of grapes increased in all major producing states and India as a whole except in Andhra Pradesh. The export of grapes from India increased over the years and Netherlands and Bangladesh were the major growing markets for Indian grapes. Growth in export to UK, UAE and other countries also showed positive trend. Chile and South Africa were major exporters of grape to the world. Preference to Indian grapes in developed countries was low. The Nominal Protection Coefficient (NCP) for grape ranged from 0.269 to 0.539 indicating highly price competitiveness of Indian grapes in international market. The major problems faced by grape growers in production were inadequate supply of manures and fertilizers and high price/non-availability of plant protection chemicals. Problems faced in marketing of grapes were Unremunerative prices and price fluctuation for market. Problems faced by grape exporters were poor preference to Indian grapes in the world market and lack of demand from importing countries in current year due to recession. In the light of results obtained, there is need of improvement in production technique and thereby quality of grapes to boost our international trade.

    Effect of irrigation on growth, yield and water requirement of wheat ( Triticum aestivum L. ) under varying water table conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-06) Jha, Kanchan; Kushwaha, H.S.
    Lysimeter and field experiments with Wheat crop var. UP-2425 were conducted at Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Latitude 29 oN, Longitude 79o 30` E and Altitude 243.84 m amsl) to know the effect of various irrigation treatments on growth, yield and water use by wheat crop during rabi season of 2007-08. Six irrigation treatments in lysimeters associated with three water tables viz; 30, 60 and 90 cm included I0 (rainfed), I1 (irrigation at 21 DAS), I2 (irrigation at 21 and 65 DAS), I3 (irrigation at 21, 45 and 80 DAS), I4 (irrigation at 40 per cent depletion of available soil moisture (ASM) and I5 (irrigation at 60 per cent depletion of ASM) in lysimeters as well as in field experiments. The analysis of data in lysimeter with six irrigation schedule, three water tables and in field with six irrigation treatment revealed that the optimum water use with irrigation at 40 per cent depletion of ASM in lysimeter with 60 cm water table was 636.06 mm and 329.09 mm, respectively for better growth and development as well as for higher wheat yield. Maximum height of the crop (91.57, 86.96 cm, respectively), maximum number of leaves per plant (8.90, 7.05) and maximum number of tillers per plant (1.10, 1.58 respectively) were observed for irrigations scheduled at 40 per cent depletion of ASM and 60 cm water table and under field experiment at 135 DAS. The results also showed that minimum days required for 50 per cent flowering were 81.00, 79.62 days and for 75 per cent flowering 82.50, 82.75 days, respectively. However, the optimum grain yield was observed to be 53.06, 38.83 q ha-1 with irrigation at 40 per cent depletion of ASM in lysimeters and in field conditions, respectively. The interaction effect studied between irrigation schedules and water table served to be significant for both yield and water use efficiency in lysimeter and field plots.

    Assessment of architects’ knowledge regarding the housing bye-laws of residential buildings at Bareilly Mahanagar
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-06) Saxena, Rakhi; Shukla, Chhaya
    Housing bye-laws are the formulation of adequate housing. Housing bye-laws are essential for harmonious, respectable and peaceful living thereby to promote a healthy, happy, and brotherly environment among all residential buildings. In general housing structure is built by somebody else (architect) and used by somebody else. So, a lot of considerations are required for adequate housing. There is a huge gap between bye-laws given by various government agencies and their practical applications at the time of construction. One of the major reasons behind that may be architects’ knowledge level regarding the housing Bye-Laws. The need was felt to assess the knowledge level of architects’ regarding housing bye-laws of residential buildings. The snow ball sampling technique with combination of purposive and random sampling technique design was used to select the respondents. A total sample of 70 architects from Bareilly Mahanagar, Uttar Pradesh. The descriptive data was collected with the help of interview schedule through personal interview method in Bareilly Mahanagar of Uttar Pradesh. The collected data was tabulated and analyzed with the help of subjective (Frequencies, percentage and mean) and relational statistics (Chi-square test) were calculated. It was concluded that the overall knowledge level regarding housing bye-laws of residential buildings at Bareilly Mahanagar was average for majority of respondents. The knowledge level pertaining specifically to technical terminology was found excellent to outstanding. Contrary to this majority of respondents were found to have below average knowledge level with regard to bye-laws related with construction of building. The knowledge level pertaining bye-laws related with safety of building was found average to good of majority of respondents. There were found a lot of deviation in housing bye-laws at the time of construction of residential buildings. Customer interest and customer choice along with financial limitations were the major factors responsible for these deviations. Deviations were found in terms of additions and deletions in doorways, windows and shelves of various areas of residential buildings. Financial factors along with value and belief of customer werefound the major limitations in implementation of housing bye-laws. Statistical analysis resulted in no association among architects’ knowledge and their age, present job experience and educational qualification.

    The present study pertaining to evaluation of different cultivars of mango for preparation of ready-to-serve beverage (RTS) was conducted in the Department of Food Science & Technology, G.B. Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar (Uttarakhand) during the year 2008-09. The cultivars differed significantly in terms of fruit weight (110.0-574.5g), length (7.18-14.59 cm), breadth (5.23-9.07 cm), specific gravity (0.953-1.061) and content of flesh (58.18-79.90%), peels (9.10-22.52%) and stone (11.05-20.55%). Variations in pH (3.75-4.49) and content of TSS (11.5-17.33%), moisture (76.32-88.65%), acidity as citric acid (0.16-0.31%), vitamin C (15.30-107.27 mg/100g), ash (0.24-0.43%); reducing, non reducing and total sugars (3.08-4.64, 8.91-15.71 and 12.52-20.36%) in flesh were statistically significant, Fazli recorded highest fruit weight, length and breadth while these were minimum with Alphanso. Fazli having maximum flesh also had highest acidity while Pant Sindoori and Dashehari recorded minimum flesh and acidity, respectively. Langra flesh was found to be the richest source of vitamin C. Dashehari, Langra and Chausa varieties were selected for making RTS of composition 10% pulp, 10% TSS and 0.30% acidity, on the basis of their highest overall acceptability score (8.67, 7.89 and 7.33, respectively). The sulfited and in-bottle pasteurized drinks prepared from these selected cultivars had >6 months of shelf-life at ambient conditions.

    A study of thermo-magnetic effects on static state of cholesteric liquid crystal between two hot co-axial circular cylinders
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-06) Gangwar, Sukhdev Singh; Sharma, A.K.
    Liquid crystal the fourth state of matter is observed between the crystalline solid and amorphous liquid states. It exihibits the properties of liquids as well as that of crystalline solid state. In the present study we have considered an infinite static layer of cholesteric liquid crystal lying between two infinite hot co-axial circular cylinders in the presence of azimuthal magnetic field when both the cylinders are held at different temperatures and are lying at rest. We have examined the thermo-magnetic effects in this problem. After obtaining the system of governing differential equations we have solved it numerically by Newton Raphson method. The results are then graphically plotted. It has been observed that orientation of molecules varies with the variation of magnetic field and temperature gradient parameters.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-06) Singh, Prem; Roy, D.
    The present investigation was carried out during 2007-08 at Horticultural Research Centre, Patharchatta of G.B. Pant University of Agriculture and Technology, Pantnagar. The experimental material comprised of a variety Farm Selection -1 of papaya. The objective was to study variation for different quantitative traits and the character association in the variety Farm Selection-1 of papaya. Observations were recorded on 112 fruiting plants for various characters namely height of the plant, height at first flower, days to flowering, leaf length, leaf width, pedicel length, number of nodes, girth of plant, number of fruits per plant, fruit weight, fruiting node length, fruit diameter, pulp thickness and cavity size. The coefficient of variability was highest for fruit number per plant and fruit weight so, these two traits showed higher variability in comparison to other traits. The coefficient of variability was lowest for leaf length and leaf width so, these traits showed lower variability in comparison to other traits. Wide range of mean values for all the fourteen traits showed immense variability present in the variety Farm Selection-1 which indicates that selection can be practiced for improvement of these traits. Phenotypic correlation coefficients were also calculated between fourteen pairs of traits. Economically important characters like number of fruit was positively and significantly correlated with fruiting node length, fruit weight, fruit diameter and pulp thickness. Fruit weight was positively and significantly correlated with fruiting node length, fruit diameter and pulp thickness. Fruiting node length was positively and significantly correlated with fruit diameter, pulp thickness and cavity size. Fruit diameter was positively and significantly correlated with pulp thickness and cavity size. Pulp thickness was positively and significantly correlated with cavity size and Cavity size was the trait which showed positive and significant correlations with other traits viz., pedicel length, girth of plant, fruit weight, fruiting node length, fruit diameter and pulp thickness.
