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.

    Studies on post harvest diseases of mango: etiology and biological control
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-07) Gupta, Sonal; Singh, U.S.
    India is the largest producer of mangoes and accounts for more than half of the world's production but it ranks third in mango export. Constraints like suitability of few varieties, short storage life, post-harvest pests and diseases etc. restrict the expansion of exports from India. Management of post harvest diseases has been mainly achieved by use of chemicals but due to public's growing health concern and limitation of use of chemicals for export purposes, we have been forced to look for alternative and safe measures for their control. The present work tries to identify the common post harvest diseases, their incidence, severity, varietal susceptibility, management with bioagents, in vitro antagonism studies and effect of bioagents on TSS and TA of fruits. Stem end rot, anthracnose, Rhizopus rot and black mold rot were the four commonly observed diseases. Gulab Khas, Alphonso and Bombay Yellow showed more susceptibility to post harvest while Dushehri, Lucknow Scrfeda and Malihabadi Safeda were relatively less susceptible. Significant in vitro inhibition of Rhizopus species was achieved by Trichoderma spp. and Pseudomonas fluorescens. Yet successful management of these diseases with post harvest fruit dips in bioagent suspensions could not be achieved when fruits were stored at ambient conditions. Langra fruits subjected to high R.H (95%, 30°C) for 12h just after dipping in suspension of biocontrol agents and then stored between 30-35°C, experienced significant reduction in post harvest rotting. In the same treatment significant difference in TSS values was recorded, maximum for P. fluorescens PBAP-28 and minimum for T harzianum PBAT-43. Thus it can be concluded that efficacy of bioagents can be increased under controlled conditions and probably their pre harvest spray will be more effective in managing post harvest diseases as compared to post harvest dips as it can allow their early colonization. In case of post-harvest dip in suspension of Trichoderma and Pseudomonas, storing of the treated fruits for 12 hours at high moisture might help biocontrol agents to multiply and colonize the fruit surface. This will enhance the efficacy of bioagents against post harvest rotting of mangoes. U.

    Studies on the multiplication and utilization of seabuckthorn (Hippophae salicifolia D. Don.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-07) Bisht, Rohit; Sharma, S.K.
    The present study was undertaken during October, 2005 to November, 2006 to standardize the techniques for multiplication of seabuckthorn by seeds as well as for preparation of processed products viz. RTS and squash from seabuckthorn and to evaluate their storage stability. Seabuckthorn berries (fruits) were harvested at optimum maturity (ripe stage) from natural population in Badrinath area of Distt. Chamoli, Uttarkhand. The seeds were separated manually from the residue left after pulp extraction and stored at room temperature (8-18oC) in paper bags, for four months before further experimentation. The seeds were treated for 18 hours with different PGR‟S and chemicals along with other treatments i.e. stratification and luke warm water. Control was also kept for comparison. The pulp was utilized for preparation of beverages (RTS and squash). The beverages were stored for six months under ambient and refrigerated conditions and evaluated for physico-chemical and sensory changes. The results reveal that IAA @ 100 and 200 ppm were most suitable treatments for various plant growth parameters, including germination and survival percentage, closely followed by Kinetin @100 ppm and GA3 @ 400 ppm indicating that seabuckthorn can successfully be propagated by seeds using different growth regulators. Seabuckthorn RTS and squash beverage were standardized at 5 per cent pulp, 14 oBrix TSS and 25 per cent pulp, 50 oBrix TSS respectively. These beverages on storage for 6 months interval experienced insignificant increase in total solids and TSS under both ambient and refrigerated conditions. However, there was a significant increase in reducing sugars of both RTS and squash beverages. On the contrary, the total sugars suffered some loss during storage period. The acidity of RTS and squash suffered slight but steady decline during storage whereas, ascorbic acid experienced loss of 76.46 and 75.46 per cent in RTS and squash respectively. The sensory scores for colour, taste and overall acceptability declined during storage. All these physico-chemical and sensory changes were less in refrigerated conditions, in comparison to ambient conditions. Further both the beverages were acceptable upto 6 months of storage.

    Harvest time residues of Fantac and Benfuracarb in rice and soil
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-06) Pant, Renuka; Bali Ram
    Benfuracarb is a new carbamate insecticide which controls a wide range of insects such as aphids, wireworms, corn rootworms, loopers, borers, and thrips in many different crops including cotton, corn, and beans. Fantac (biostimulant) is a mixture of 5% N-acetyl thiazolidine carboxylic acid (L-cystine derivative) and 0.1% folic acid. It is used to stimulate seed germination, increase plant growth, improve fruit rating and increase yield on wide range of crops including wheat corn, rice, sugar beet, potatoes, grapes strawberry and apples. Harvest time residues of Benfuracarb and Fantac in paddy grain, husk, straw and soil were determined. Benfuracarb formulation (Oncol 40EC) was applied at the rate of 0.25 and 0.50 ppm and Fantac formulation was applied at the rate of 0.75 and 1.50 ppm. The analysis of the samples was done by high performance liquid chromatography.The results revealed that the residues of Benfuracarb and Fantac were non detectable (<0.01ppm) for both the treatments. Benfuracarb and Fantac are safe from environmental and health points of view as their residues if presentare in very lowconcentrations both in crop and soil at the time of harvest.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-06) Joshi, Reena; Tewari, Salil Kumar
    The present investigation entitled “Studies on Macro and Micro Propagation in Bamboo” was carried out at new site of Agroforestry Research Centre, Haldi, Pantnagar during June 2006 to May 2007 and in tissue culture laboratory of the Agroforestry Section, College of Agriculture, G.B. Pant University of Agriculture and Technology, Pantnagar. Experiments were conducted to see the effect of age (one and two year old), growing condition (open intermittent misting and open no misting), position (basal, middle and top) in different seasons (June, August, October and March) on rooting and sprouting of culm cuttings of Bambusa balcooa and Dendrocalamus asper. The findings indicated that two year old culm cuttings collected from basal position in the intermittent misting condition gave best response in B. balcooa. In D. asper, one year old culm cuttings with above condition showed good results. The findings also indicated that rooting and shooting per cent of culm cuttings planted in different season showed response as March> June> August> October in both the species. For micropropagation nodal buds from one year old B. balcooa and D. asper were taken as ex-plant. In B. balcooa for sterilization 0.1% Tween-20 (5 min), (1.0% Bavistine (5 min), 0.1% Streptomycin (4 min), 70% Ethanol (5 min), 1.0% NaOCl (8 min) and 0.1% HgCl2 (3 min)), for bud break (3.0 ppm BAP+ 1.0 ppm GA+ 0.5 ppm Kinetin), for proliferation of bud (4.0 ppm BAP+ 0.5 ppm Kinetin) and in D. asper 0.1% Tween-20 (5 min), (1.0% Bavistine (4 min)+ 0.1% Streptomycin (3 min)+ 70% Ethanol (5 min)+ 1.0% NaOCl (10 min)+ 0.1% HgCl2 (5 min)) for sterilization, (3.0 ppm BAP, 0.5 ppm Kinetin+ 0.5 ppm GA) for bud break, (5.0ppm BAP+ 1.0 ppm) for proliferation of bud were found to be best for this investigation. In vitro rooting studied using different auxins; 3 ppm NAA+2.5 ppm IBA and 4 ppm+ 2 ppm IBA were found to be best for B. balcooa and D. asper respectively.

    Socio-economic assessment of market value chain and post harvest loss of potato in Burdwan district of West Bengal
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-07) Karar, Rajesh; Agnihotri, A.K.
    The study was conducted in Burdwan district of West Bengal by selecting fifty respondents, including potato growers, wholesalers, retailers, processors etc. to fulfill the objectives, viz, to find out the effect of human skill on net margin earn, to identify the market value chains prevail for potato marketing, to estimate the post harvest loss of potato in Burdwan district, to prioritize the constraints in value chain management and to examine the marketing efficiency of different market value chains. Different market value chains were identified through Rapid Market Appraisal Technique, post harvest loss of potato was estimated using simple statistical tools like average and percentage, whereas, in order to examine the effect of human skill on net margin earn, regression analysis technique (linear regression equation) was used, marketing efficiency of different value chains were calculated by using Shepherd formulae and for prioritizing the constraints Garrett Ranking Technique was used. Human skill has positive effect on growers’ net margin. Higher the skill higher the margin they earn. Potato was transacted through five different value chains in district Burdwan. In case of potato it was found that 35 per cent of potato was loss after harvest. This year the post harvest loss of potato was more because of high rainfall during harvesting season and occurrence of late blight, which is an epidemic disease for potato. Economic post harvest loss of potato was more or less same as physical post harvest loss but economic post harvest loss at field level was more compare to that of physical post harvest loss. The reason behind this is, at field level production is govern by many uncertain factors, like weather and disease outbreak. In case of marketing of potato it was found that, share of potato growers in consumers’ rupee was only 52-72 per cent. Producers’ share in consumers’ rupee was highest in channel V, where only retailer was involved between them but it was identified as less efficient value chain. In case of potato processing, it was found that, there has an ample opportunity for processors, regarding the market for processed potato products in future.

    Pathogenesis of susceptible and resistant strains of Haemonchus contortus in sheep
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-01) Rajanish Kumar; Yadav, C.L.
    Haemonchus contortus is the most pathogenic gastrointestinal nematode of sheep and goats. The anthelmintics are the only practical method to reduce the menace of haemonchosis. The indiscriminate use of anthelmintics has led to emergence of resistant strain/subspecies of H. contortus throughout the world. There are numerous reports of benzimidazole resistance in H. contortus from the world as well as India. The present study was planned to investigate differences in biological behaviour and pathogenecity of susceptible and FBZ resistant strain of H. contortus. The prepatent period of 17-18 days was recorded for both the strains. The mean total worm recovery of susceptible (1777.5), resistant (2680) and naturally infected sheep (1565) were recorded. The sex ratio, body weight loss and establishment rates were also measured for the both strains. The faecal egg count for susceptible strain 1683±33.0, for resistant strain 3775±118.3 and 1850±99.9 for naturally infected sheep were observed. Significant difference were observed between susceptible and resistant strain for worm count, sex ratio and establishment rates. The degree of reduction in PCV and Hb% indicated pathogenecity of worms but no significant differences were observed between susceptible and resistant strains. Peripheral eosinophil count and total erythrocytic count indicated significant difference between the two strains. The erythrocytic indices indicated normocytic, normochromic anaemia. The total iron levels of resistant strain infected group decreased significantly as compared to susceptible strain infected group. The total serum protein reduced from 6.95 ± 0.37 to 582 g/dl, 6.79 ± 0.20 to 3.53 ±0.28 and 6.88 ± 0.19 to 4.92 ± 0.47 from the day of infection to 49 DPI in susceptible, resistant strain infected sheep and sheep infected by grazing, respectively. The serum albumin levels also mirrored similar trends to total serum protein. Thus, hypoproteinaemia and hypoalbuminaemia was significantly more in resistant infected sheep. The serum pepsinogen level increased from 1.10 ± 0.23 to 2.67 ± 0.12 IU tyrosine in susceptible strain, 1.19 ± 0.27 to 3.23 ± 0.31 in resistant strain infected sheep and 1.37 ± 0.25 to 3.22 ± 0.03 IU tyrosine in sheep infected by grazing. Significant differences were recorded with regards to serum pepsinogen level between the two strains indicating higher abomasal damage in resistant strain infected sheep. Thus, it can be inferred that both the strains are different in their biological behaviour and the pathogenecity, with resistant strain being more pathogenic than susceptible strain.

    Nutritive value and popping quality of some genotypes of finger millet
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-06) Chaturvedi, Radhika; Srivastava, Sarita
    Millets are rich sources of dietary fiber, phytochemicals, micronutrients and nutraceuticals and hence also termed as nutricereals .It is well accepted fact that millet consumers suffer less from some of the major physiological disorders such as diabetes mellitus, cardiovascular diseases, constipation, hypercholesterolemic problems, duodenal ulcer and obesity. Finger millet is the third largest crop of Uttarakhand .Finger millet is the richest source of calcium (344 mg/100g).The millet protein has balanced amino acid profile and good source of methionine and cystine. With the changes in scenario of utilization of processed food products and awareness of the consumers about health benefits finger millet has occupied a pride of place because of its functionalities, popping being a simple traditional technology enables to produce ready to eat foods which can be gainfully utilized for the production of low cost nutritious food supplements. The present study was carried out to investigate the physical properties, popping quality, sensory quality and nutritive value of some genotypes of finger millet. Grains of six genotypes (five brown and one amber) of finger millet (Eleusine coracana) were procured from department of plant pathology, College of Forestry and Hill Agriculture, Ranichauri. Analysis of physical characteristics and popping qualities of all six genotypes was done. Nutrient analysis of finger millet flour was done both before and after popping, to evaluate changes in nutrient composition on popping .Popped grains of all six genotypes were analyzed for their sensory quality by nine point Hedonic scale and score card method .The popping percent ranged from 54.0 (VL-315) to 84.0 (PES-400), amber colour genotype PRM-701 exhibited 74.0 percent popping. The results obtained have shown that amber colour genotype contain significantly higher amount of protein and iron than brown genotypes. After popping significant decrease was seen in moisture content. Significant differences were seen in proximate composition among different genotypes but no significant difference was seen before and after popping except in moisture content and energy value. In vitro protein digestibility improved on popping. Prolamin was found the dominating protein fraction in finger millet. No significant difference was found on the basis of sensory quality among all six genotypes in score card method, and nine point Hedonic scale.
