Effect of Foliar Application of Di-Ammonium Phosphate on Growth and Yield of Blackgram

Abstract

A field experiment was conducted on CO 4 blackgram (Vigna mungo (L.) Hepper) to study the effect of 3%, DAP (18:46: O/NPK) as foliar spray. DAP was sprayed once at commence- ment of flowering and then a fortnight later as compared with water spray at the corresponding stages. The results indicated that spraying of 3% DAP twice increased the number of pods per plant, shelling percentage, hundred grain weight and ultimately resulted in increased grain yield.
