Effect of foliar application of macronutrients (N, P and K) on growth in different growth stages of green gram

The field experiment was carried out on “Effect of foliar application of macronutrients (N, P and K) on growth and yield of green gram.” During kharif season of the year 2017-18 at the Research farm of College of Agriculture, Latur. The experiment was laid in randomized block design with three replications and variety BM 2003-2 as a test crop along with eight treatments viz., T1 - Control, T2 - RDF + Water Spray, T3 - RDF + 19:19:19 @ 0.5 % at vegetative stage, T4 - RDF + 00:52:34 @ 1.0 % at flowering stage, T5 - RDF + 13:00:45 @ 1.0 % at grain filling stage, T6 - T3 + T4, T7 - T4 + T5 and T8- T3 + T4 + T5.The results of field study indicated that, the growth, yield uptake and quality of green gram were significantly influenced by foliar application of macronutrients (N, P and K). The growth parameters viz., plant height, number of branches, number of leaves plant-1, leaf area plant-1, number of pod plant-1 and dry matter of greengram were significantly improved due to treatment T8 (RDF + 19:19:19 @ 0.5 % at vegetative stage, RDF + 00:52:34 @ 1.0 % at flowering stage and RDF + 13:00:45 @ 1.0 % at grain filling stage). Whereas, yield contributing characters viz., seed yield, straw yield and biological yield as well as quality parameters such as protein content, protein yield and test weight of seed in green gram were also increased.
