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.
Bambusa bambos (L.) Voss, popularly known as Indian Thorny Bamboo is in high demand due to its multipurpose importance. It is cultivated for building and raw material for pulp and paper industry. Being the fastest growing woody plant, it has important role in repairing damaged and degraded soil outside forests. Availability of planting materials is a constraint, as the natural propagation methods have limitation. Tissue culture offers rapid and reliable method to produce planting materials on large scale in lesser time. The current study was taken up with an objective to optimize an efficient system of micropropagation using nodal segments. Choice of explants and different media formulations were standardized for shoot induction, shoot multiplication, rooting and hardening. Nodal segments of 3.0 mm girth and 3.0 cm length beneath the node induced 4.5 shoots per explants in liquid MS basal media supplemented with 3.0 mg/l BAP and 2.0 mg/l TDZ. Shoot multiplication with 20.8 shoots per clump was obtained liquid MS media supplemented with 6.0 mg/l BAP, but the length of shoots originated went on decreasing with the increase in BAP concentrations. Among various concentrations of NAA and BAP, 9.0 mg/l NAA alone gave 18.7 roots per explants. Among the IBA and BAP hormonal combinations, IBA at 20.0 mg/l gave a maximum of 18.4 roots per explants. Total number of roots originated per explant increased significantly with the increase in concentrations of auxins. But within a particular concentration of auxins, the number of roots decreased significantly with the increase in the concentrations of BAP, particularly at the higher concentrations of auxins. NAA at 9.0 mg/l and IBA at 20.0mg/l were at par in terms of root regeneration. In the media containing both NAA and IBA was associated with necrosis, which increased with the concentration of auxins, while within a particular auxins concentration; it decreased with the increase in BAP concentration. Four different potting mixtures including coco-peat, soil, sand and vermi-compost, did not show significant difference, but the days of emergence of new shoots was lesser in coco-peat: soil: sand: vermi-compost (1:1:1:1:1) potting mixture (23.9 days). The optimized procedure may effectively be used for large scale planting material production of Bambusa bambos (L.) Voss.
