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.

    Mineral nutrient accumulation during fruit growth of Mango (Mangifea indica L.)
    (Deptt. of Hort. (Fruit & Fruit Tech.), BAU, Sabour, 2014) Sinha, Rajni
    The interpretation of fruit analysis must consider many factors that may influence foliar nutrient levels, seasonal differences related to rainfall, fruit load, pruning, age, variety, rootstock, nutritional interaction and nutrient removal. Information about the nutritional status of a plant is a basic prerequisite for its adequate nutrition and crucial to achieve high yield productivity. Assessing the annual amount of nutrient that tree needs to absorb in order to successfully complete a vegetative and reproductive growth is a fundamental step for developing rational fertilization in orchards. Accordingly the investigation entitled “Mineral nutrient accumulation during fruit growth of mango (Mangifea indica L)” was carried out in the department of horticulture fruit and fruit technology BAC, Sabour during 2013. For conducting this experiment fruit of variety Dashehari, Langra, Mahmood Bahar, Menka, Sabri, Langra, Zardalu were collected at different stages like Marble, Prestone formation, Stone hardening & Harvest stage for estimation of primary nutrient (N, P, K), secondary nutrient (Ca, Mg) µnutrient (Fe, Mn, Zn, Cu). Variety Sabri absorbed highest amount of N, Fe and Mn among all varieties which were under investigation. While as P accumulated maximum in Dashehari. Sundar Langra accumulated highest amount of K. There were not significant variation in Ca content among varieties. Moreover Mahmood Bahar accumulated the maximum amount of Mg and Cu. Zn was present maximum in Menka. The nutrient content particularly N, K, Mg, Mn and Zn were recorded highest at marble stage while as P was accumulated maximum in pre stone formation stage and Fe & Cu was in stone hardening stage. There were least variation was observed in Ca content. However interaction of varieties & stages were also highlighted. The nutrient removal by the fruit were also estimated. Data revealed that the total removal of nutrient depend on age of tree and its production which will also be highlighted. Hence, the removal of nutrient by the fruits should be taken into consideration for fertilizer scheduling.
