Effect of Foliar Nutrition on Water Potential, Photosynthetic Rate, Dry Matter Production and Yield of Mung Bean under Receding Soil Moisture Condition

چکیده
A field experiment was conducted during Rabi season of 2012-13 at Regional Agricultural Research Station, Lam, Guntur, with an aim to find out the effect of foliar nutrition on water potential, photosynthetic rate, dry matter production and yield of mung bean under receding soil moisture conditions in split plot design with irrigation and no irrigation as main treatments and foliar sprays as sub treatments. Under receding soil moisture condition (moisture stress) KNO3 @ 1% proved superior over other foliar sprays by recording more plant height, leaf area, shoot dry weight, and photosynthetic rate by maintaining high chlorophyll content, high proline and high leaf water potential. KNO3 @ 1% gave higher yields under receding soil moisture condition compared to other foliar sprays. Under irrigated conditions urea @ 2% recorded higher yield. Among all treatments controlled (no spray) under unirrigated conditions recorded lower yields due to moisture stress and nutrient deficiency.
