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

Abstract:

Due to rapid growth and early maturity, mungbean (Vigna radiata L.) is adopted into multiple cropping systems in the drier and warmer climates of the lowland tropics and sub-tropics. Although mungbean has a number of advantages in terms of food value, production and crop management, the area and production is not increasing proportionately in comparison with other cereals. With the advent of high yielding varieties of rice and wheat the production of cereal crops increased manifold during the past four decades with the concomitant decrease in area and production of pulses. In view of growing demand of the cereal crops it is unlikely that the HYV cereals would give way to pulses like mungbean. In Bangladesh, extensive cultivation of mungbean is constrained by strong competition with rice, particularly during wet season.
There are two approaches to overcome nutritional deficiency of soils and crops, one is to fit the soil through supplement nutrients to the crops and the other is to fit the crops or crop varieties to the soils.
Generally nutrient deficiency of a soil is corrected through application of chemical fertilizers. Fertilizers on one hand are costly and on the other hand it may lead to water pollution by nitrogen and phosphorus from agricultural land. Screening of genotypes for nutrient stress tolerance could be the best alternative to overcome the situation. The present study evaluates the plant growth characters with emphasis on root growth and nutrient uptake of selected mungbean genotypes and examines the efficiency of certain growth parameters for predicting their adaptation in sub-optimal nutrient environment. Some genotypes (VC 6153B, GK3 & VC 6144A) were found to be high nutrient acquiring genotypes and some (PDM 54, IPSA 25 & VO 1443 A-G) were low nutrient acquiring genotypes.
