Abstract: A field experiment was conducted to evaluate the influence of foliar spray of nutrients on yield and economics of soybean during rabi 2011 at Tamil Nadu Agricultural University, Coimbatore. The experiment was laid out in randomized block design replicated thrice. The results revealed that foliar spray of 2% DAP twice at flower initiation and pod formation stages of crop growth resulted in significantly higher number of pods-1 (62.50), number of seeds pods-1, seed index and higher grain yield (1460 kg ha-1). It was on par with 2% urea phosphate and TNAU pulse wonder spray. The foliar spray of 2% DAP also recorded significantly higher net return of Rs 20,090 with B:C ratio of 2.22.
