Abstract

A study was conducted in Uttar Pradesh, India, during kharif 2002 to examine the response and nutrient uptake of urdbean and mung bean genotypes to optimum nutrient supply on nutrient-deficient sandy loam soil. Treatments comprised: control (no nutrient supply) and optimum nutrient supply (20 kg N, 60 kg P, 20 kg K, 20 kg S and 25 kg Zn/ha, on a weight basis). Irrespective of the crop and genotypes, root and shoot biomass significantly increased with optimum nutrient supply compared to the untreated control. Shoots responded more conspicuously to optimum nutrition than roots in both crops. Mung bean responded to nutrient supply to a greater extent in terms of root, shoot and total biomass than urdbean. The extent of dry matter and biomass yield response to optimum nutrient supply also varied between the crops. Shoot N content in both crops showed significant correlation with shoot dry matter yield in both treatments, and correlation coefficient values varied from 0.81 to 0.87 in urdbean and from 0.75 to 0.76 in mung bean. With optimum nutrient supply, N uptake increased to more than two-fold over the control, ranging between 20.1 and 78.5 mg/pot in urdbean and between 27.5 and 59.8 mg/pot in mung bean. With optimum nutrient supply, shoot P content increased in both crops compared to the control. Genotypes with higher P content showed higher shoot dry matter yield. In urdbean, P uptake varied from 0.69 to 1.75 mg/pot in the control, and 1.60 to 5.29 mg/pot in optimum nutrient supply. In mung bean, P uptake ranged from 0.37 to 1.54 mg/pot in the control, and 1.52 to 3.76 mg/pot in optimum nutrient supply.
