The effect of waterlogging and foliar sprays on plant height, leaf area, No. and fresh weight of nodules, stomatal conductance, relative water content and pod yield was investigated at different time intervals in a pot culture experiment conducted at Agricultural College, Bapatla during rabi 2001. Waterlogging was imposed from 20 to 30 DAS and 50 to 60 DAS. Five foliar sprays were given after alleviating waterlogging viz., (i) water (ii)urea (0.5%), (iii) Urea (0.5%) + Sucrose (0.25%) (iv) Urea (0.5%) + K2SO4 (0.25%) and (v) Urea (0.5%)+Sucrose (0.25%). Besides these control plants were maintained without waterlogging and without foliar sprays. At every stage, control had maximum values indicating that waterlogging was detrimental to growth though supplemental nutrition through foliar sprays were given. Among foliar sprays maximum pod yield was found in Urea and Potassium sulphate.
