INFLUENCE OF FERTILIZER LEVELS AND SULPHUR ON YIELD, YIELD ATTRIBUTES AND ECONOMICS OF BT COTTON
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 58
Abstract
A field experiment was conducted during Kharif, 2013 at Agricultural college farm, Bapatla. The experimental soil was clay loam in texture, non saline, slightly alkaline in soil reaction with low organic matter, low available nitrogen, medium phosphorus, very high potassium and sufficient micronutrients. Results showed that highest plant height was recorded in where 150 per cent RDF + S @ 30 kg ha-1(T9) was applied, where as highest yield, dry matter accumulation, number of sympodial branches per plant, boll weight and boll number were recorded in the treatment which received 125% RDF + S @ 30 kg ha-1. Sulphur application along with 100, 125 and 150% RDF increased the kapas yield over the 100, 125 and 150 per cent RDF application alone. Among all the treatments 125% RDF + S @ 30 kg ha-1 imposition resulted in higher cost benefit ratio followed by soil test based recommendation.
