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.

    Study on performance of seed treatment with micronutrients in paddy (Oryza sativa L.)
    (Department of Seed Science & Technology, BAU, Sabour, 2021-01) Afreen, Samruzzoha; Kumar, Arun
    Paddy is a nutritive staple food and one of the most important cereal crops, especially for people in Asia. It has good digestibility, biological value and good quality protein due to the presence of higher amount of lysine. India rank 2nd in the world in terms of production as well as area for paddy after China. Bihar ranks 6th in production. The total area under paddy covers in India is 43.8 million hectares with annual production of 112.91 million tonnes and productivity of 2578 tonnes per hectare. Micronutrients stored in seeds and grain are essential for initial crop growth during germination and early seedling establishment. Zinc is important for maintaining the integrity of biological membranes, protein synthesis, photosynthesis, pollen formation and disease resistance and important component in plant enzymatic systems. Iron also play an important role in metabolic processes such as DNA synthesis, respiration photosynthesis, chlorophyll synthesis, plays significant role in various physiological and biochemical pathway. Seed enhancements include physical, physiological and biological treatments to overcome germination constraints by uniform stands, earlier crop development and better yields. Seed nutripriming is an effective technology for enhancement in quality of seed as well as enrichment of seed with micronutrient at basic level. The experiment was carried out to assess the performance of nutirpriming in paddy crop. The material comprised of single lot of paddy variety Sahbhagi dhan and seed material was undergone different seed enhancement treatments with micronutrient (FeSO4 and ZnSO4) solution with four level of concentration viz., 0.25, 0.5, 1.0, 2.0 % for 24 hours in ratio of 1:2 (kg of seeds/volume of solution) to assess their effect on physiological, field parameters and relative storability. Then the treated seeds were dried in room temperature to maintain the initial seed moisture content. After seed treatment incubation study has done. On the basis of findings of incubation study seed was tested for laboratory parameters as well as storability. All the laboratory parameters viz., standard germination (SG), seedling dry weight, seedling length, seedling vigour index-I & II show lower value in untreated seed and hydroprimed seed as comparison to treated seed. Seed treatment with FeSO4 (2.0 %) shows significantly higher seed germination, seedling length, seedling vigour index-I (SVI-I) and iron content in seedlings and lowest EC among all treatments. All the fields parameters viz., plant height, panicle length, number of productive tillers/hill, number of tillers/m2, number of panicle/m2, number of seed/panicle, seed index), harvest index per hill, seed yield/m2, seed yield/hill recorded higher value in treated seed over control and hydropriming. Seed treatment with FeSO4 (0.5%) recorded significantly higher number of tillers/m2, number of panicle/m2, seed yield/m over control and hydropriming. Treatment with ZnSO4 (foliar spray 0.5 %) recorded significant enhancement in panicle length over control and hydropriming. Seed treatment with ZnSO4(0.5%) recoded highest no. of seeds /panicle among all treated and untreated seed. Treatment with FeSO4 (2.0 %) recorded significant enhancement in number of productive tillers/hills, plant height, seed yield/hill, harvest index/hill, higher content of zinc in seed over control and hydropriming. Observation were also recorded on seed quality parameters of harvested (progeny) seed. FeSO4 (0.5%) showed higher seedling dry weight and SVI-II and FeSO4 (0.25%) for higher root length, shoot length and SVI-I. Further, FeSO4 (2.0 %) showed higher zinc and FeSO4 (soil) showed for higher iron content in seed. Vigour of the seed lot is directly and positively correlated with storability of the seed lot. Standard germination, SVI-I and II, of treated and harvested seed lot for zero- and three-month storability recorded highest result over untreated and hydropriming. In case of electrical conductivity (EC), treated and harvested seed recoded significantly less value for both zero- and three-month storage period, which is good symbol of enhancement of seed storability life. Seed treated with FeSO4 (2.0 %) shows significantly higher SG, SVI-I and lowest EC as compared to control and other treatment for both 0 month and 3month of storage period. Overall, seed treatment with micronutrient (Fe and Zinc) improves the seed quality as well as growth and yield attributes in Paddy. Seed treatment with FeSO4 (2.0 %) improves all seed quality as well growth and yield attributes. Storability of seed lot also improves upon treatment with FeSO4 (2.0 %) and is better among all treatment under study. Seed treatment with FeSO4 (2.0 %) improves both iron and zinc content in seed, but in plant, ZnSO4 (1.0 %) is more effective.
