Effect of foliar application of antioxidant on growth and yield of soybean

Abstract

The present study was carried out under the field conditions at Post Graduate Institute Research Farm, Department of Agricultural Botany, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist Ahmednagar (M.S.) during kharif season 2017 and 2018. Two varieties of soybean viz., V1 - KDS-726, and V2 - KDS-344 were foliar spray with antioxidants viz., T0- Control, T1- Ascorbic acid (100 ppm), T2- Salicylic acid (100 ppm), T3- Humic acid (2000 ppm), T4- Perrydoxin (100 ppm), T5- Salicylic acid (100 ppm) + Ascorbic acid (100 ppm). The field experiment was conducted in Split Factorial Design with three replications. In the field experiment, growth and yield observations such as plant height, number of primary branches per plant, leaf area, seed yield per plot (kg) and seed yield per ha. (QT). Among the foliar application of antioxidants treatments, application of (T1) ascorbic acid (100 ppm) exhibited higher plant height, number of primary branches per plant, leaf area, seed yield per plot (kg) and seed yield per ha. (QT). The interaction of variety KDS-344 (V2) and foliar application with (T1) ascorbic acid (100 ppm) (V2T1) resulted in significant increase in plant height, number of primary branches per plant, leaf area, seed yield per plot (kg) and seed yield per ha. (QT). From present study, it is concluded that the soybean variety KDS-726 (V1) and KDS-344 (V2) with foliar application of ascorbic acid (100 ppm) exhibited improved growth and yield of soybean.
