SOYBEAN (Glycine max L.) RESPONSE TO MICRO-NUTRIENTS

Abstract

Soybean (Glycine max L.)  generally, respond to micro-nutrients by enhanced nodulation and more seed yield. A field trial was carried out to evaluate the response of soybean to micronutrients viz. iron (Fe), molybdenum (Mo) and cobalt (Co). Results indicated that iron applied at the rate of 400 g ha-1 and molybdenum @ 20 g ha-1 had a significant effect on shoot length, shoot dry weight, number of nodules plant-1, nodules fresh weight and thousand seed weight. The highest seed yield 42.28% over control, dry matter yield, seed nitrogen and seed protein content was recorded by combined application of Fe at the rate of 400 g ha-1 and Mo @ 20 g ha-1.
