Abstract

A field experiment was conducted to evaluate the influence of foliar nutrition and growth regulators on the yield and economics of greengram during summer at Tamil Nadu Agricultural University farm, Coimbatore. The experiment was laid out in a randomized block design with ten treatments in which urea, DAP, salicylic acid and sodium molybdate were applied either alone or in combination and replicated thrice. The results revealed that foliar applications of 2% DAP+100 ppm salicylic acid + 0.05% sodium molybdate twice at vegetative and flowering stages of crop growth recorded better yield parameters and economics. However, all the yield attributing parameters recorded under 2% urea+100 ppm salicylic acid + 0.05% sodium molybdate twice were on par with 2% DAP+100 ppm salicylic acid + 0.05% sodium molybdate twice.

Keywords: Greengram, urea, DAP, salicylic acid, sodium molybdate.
