Effect of foliar application of macronutrients and growth regulators on growth and yield of on ricefallow black gram (vigna mungo l.)

A field experiment was conducted at Experimental farm, Department of Agronomy, Annamalai University, Annamalai Nagar, to study the effect of foliar application of macronutrients and growth regulators on growth and yield of on rice fallow black gramduring January to April 2011.The experiment was laid out in randomized black design with three replications. The treatment comprised of T1- Control (Water Spray) T2- 2% DAP foliar spray at pre flowering and pod filling stage,T3 - 2% Urea foliar spray at pre flowering and pod filling stage, T4 -Panchakavya foliar spray at pre flowering and pod filling stage,T5 - 2% DAP + NAA 40 ppm at pre flowering and pod filling stage,T6 - 2% Urea + NAA 40 ppm at pre flowering and pod filling stage,T7-Panchakavya+ NAA 40ppm at pre flowering and pod filling stage. Among treatments, foliar application of 2% DAP + NAA 40 ppm twice at pre flowering and pod filling stage, favourably increased the growth, yield attributes and yield of black gram as compared to the other treatments. Based on the above results, it could be concluded that cultivation of rice fallow blackgram with foliar application of 2% DAP + NAA 40 ppm twice at pre flowering and pod filling stage was promising combination registered higher growth attributes, yield attributes, grain and haulm yields
