Effect of foliar sprays of Ethrel on growth of soybean

Abstract

The present study examined the effectiveness of foliar sprays of ethrel on growth and yield of soybean (Glycine max). A field experiment was conducted at an experimental farm of Botany section, College of Agriculture, Nagpur by growing soybean during the kharif season in the crop area spanning from July 2013 – November 2013, using randomized block design. The effectiveness of foliar sprays of ethrel was studied as control (water spray) and with 5 different levels of ethrel (100, 150, 200, 250 and 300 ppm). Soybean plants were sprayed two times at 15 day intervals at 30 and 45 DAS with different concentrations of ethrel. Recorded data showed that all morpho-physiological parameters including plant height, number of branches, leaf area, dry matter production, RGR and NAR as well as yield ha-1 of soybean plants showed positive and significant responses with the foliar application of 150 ppm ethrel followed by 100 ppm ethrel when compared with control.
