Bihar Agricultural University, Sabour

Bihar Agricultural University, Sabour established on 5th August, 2010 is a basic and strategic institution supporting more than 500 researchers and educationist towards imparting education at graduate and post graduate level, conducting basic, strategic, applied and adaptive research activities, ensuring effective transfer of technologies and capacity building of farmers and extension personnel. The university has 6 colleges (5 Agriculture and 1 Horticulture) and 12 research stations spread in 3 agro-ecological zones of Bihar. The University also has 21 KVKS established in 20 of the 25 districts falling under the jurisdiction of the University. The degree programmes of the university and its colleges have been accredited by ICAR in 2015-16. The university is also an ISO 9000:2008 certified organisation with International standard operating protocols for maintaining highest standards in teaching, research, extension and training.VisionThe Bihar Agricultural University was established with the objective of improving quality of life of people of state especially famers constituting more than two third of the population. Having set ultimate goal of benefitting society at large, the university intends to achieve it by imparting word-class need based agricultural education, research, extension and public service.

    Grafting in parthenocarpic cucumber (Cucumis sativus L.) for yield and quality
    (Department of Horticultural (Veg. Science), BAU, Sabour, 2020) Anand, Kunal; Bhardwaj, Ajay
    The cucumber productivity of India/Bihar is almost half compared with the world’s productivity. Vegetable grafting is one such technique which can cater the needs of increasing productivity up to some levels. Grafting technique combines the vigorous root system of a plant with otherwise susceptible stem portion of another plant which has economic interest. The root system is called the rootstock, and the upper part which has economic interest is called scion. To explore the full potential in terms of productivity in parthenocarpic cucumber, the study on ҅Grafting in parthenocarpic cucumber (Cucumis sativus L.) for yield and quality’ was conducted at polyhouse complex of Department of Horticulture (Vegetable and Floriculture), BAU, Sabour, District-Bhagalpur, Bihar in the year 2019-2020 with the following objectives: 1) to identify suitable rootstock for yield and quality of parthenocarpic cucumber and 2) comparative study of grafted and non grafted parthenocarpic cucumber plants. The study included nine rootstocks viz., three from pumpkin, two of bottle gourd, two from sponge gourd, one from summer squash and one from monoecious cucumber grafted with parthenocarpic cucumber genotype adopting one cotyledon grafting method. The experiment was laid out in randomized block design with three replications and ten treatment combinations in the naturally ventilated polyhouse. The data for 22 traits was recorded viz., graft survival rate (%), number of leaves per plant (20, 40, 60 days after transplanting and at final harvest), node number to first female flower, days to first female flower, days to first harvest, number of fruits per vine, fruit yield (Kg/vine), fruit weight (g), fruit length (cm), fruit girth (cm), root length (cm), root fresh weight (g), root dry weight (g), vine length (cm), total soluble solids (˚brix), ascorbic acid content (mg/100g FW), chlorophyll ‘a’ content (mg/g FW), chlorophyll ‘b’ content (mg/g FW) and total chlorophyll content (mg/g FW). The data for 22 characters were subjected to analysis of variance and mean sum of squares due to genotypes was found significant for all the characters under study except for days to first harvest. The maximum graft survival percentage (21 days after grafting) was recorded in the combination of parthenocarpic cucumber (BRPCU-1) grafted on pumpkin (Chakor) rootstock and least in sponge gourd (Rajendra Nenua-1). The graft combination of parthenocarpic cucumber (BRPCU-1) grafted onto sponge gourd (Patna Local) rootstock produced significantly earlier first female flowers at lower nodes followed by sponge gourd (Rajendra Nenua 1) rootstock then non-grafted control. The rootstock of monoecious cucumber (Swarna Sheetal) with average fruit weight of 120.48 g, fruit yield of 3.19 Kg per vine and fruit length of 19.27 cm, was significantly superior then non grafted control. None of the grafted treatments surpassed non grafted check (BRPCU-1) for root dry weight, root length and vine length. The grafting combination of parthenocarpic cucumber scion (BRPCU-1) with rootstock of bottle gourd (Rajendra Chamatkar) recorded significantly superior total soluble solids whereas the pumpkin rootstock (Chakor) recorded significantly superior ascorbic acid content than non grafted parthenocarpic cucumber control. All the grafting combinations for total chlorophyll content revealed significant superior value than non grafted parthenocarpic cucumber control except the rootstock of sponge gourd (Rajendra Nenua-1) which was at par with the control. It can be concluded that the graft combination of monoecious cucumber (Swarna Sheetal) as rootstock and parthenocarpic cucumber as scion was the best for yield, and the rootstock bottle gourd (Rajendra Chamatkar) for quality purpose. From the study it was found that genotypic variability in selection of rootstock shows significant different results. Hence, to avail maximum benefits, the specific rootstocks can be identified before adopting the grafting technique at commercial level.
