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.
Key words : Greengram, urea, DAP, salicylic acid, sodium molybdate.
