Title : Screening of mung bean (Vigna radiata) genotypes for nutrient stress tolerance

Abstract:

Mungbean (Vigna radiata L.) Wilczek) is an important grain legume grown in the tropical and subtropical regions of the world. It is one of the important sources of protein for both man and domestic animals. Another important feature of mungbean is its ability to fix atmospheric nitrogen in symbiosis with nodule forming rhizobium bacteria. Nutrient stress soil was defined soil contains nutrient below the critical level (FRG, 2005). Mungbean is a short duration crop and very effective for intensive cropping system. Mungbean can be easily fitted in mungbean – T. aus – T. aman (southern region), mungbean - aman -wheat (north western region) and mungbean - aus - aman - potato (northern region) cropping systems without considering the fertility status of the soil. One of the reasons of ignoring soil fertility in mungbean cultivation is its ability to fixation of atmospheric nitrogen. However, amount of nitrogen fixed by microbial association varies over different soil types and environmental factors, which might not be sufficient for proper growth and yield formation of mungbean. Most of the researchers evaluated mungbean genotype in optimum soil condition but they ignored low nutrient environments for evaluation of mungbean. The seed yield of mungbean however, remains extremely low in Bangladesh compared with the yield potential (Hossain et al., 2009). One of the major limitations of mungbean productivity is soil fertility as many soils of the country are inherently poor in plant nutrients. This is especially true for char areas where sand particles dominate in soil texture. Under the limitation of soil fertility seed yield of mungbean may be increased either by genetic improvement or by identifying genotypes that are efficient in nutrient accumulation in plants. Therefore, the present study was undertaken with a view to identifying potential ones by screening a large number of mungbean genotypes under nutrient stress soil.
