Physiological growth, quality and economics of sesame (Sesamum indicum L.) as influenced by application of sulphur with use of farmyard manure

A field experiment was conducted at college farm, college of agriculture, Rajendranagar during kharif season of 2014 to study the effect of different levels of sulphur on physiological growth, yield quality and economics of kharif sesame with application of farmyard manure. The experiment was laid out in split-plot design with two main treatments viz., M1- RDF (40-60-40 kg NPK ha-1), M2- RDF along with application of 25% N through farmyard manure and three sub treatments viz., S1- 10 kg S ha-1, S2- 20 kg S ha-1 and S3- 30 kg S ha-1. Application of RDF along with 25 % N through FYM recorded highest physiological growth [Leaf area index (1.86), crop growth rate (6.98 g m-2 day-1), relative growth rate (0.054 g g-1 day-1) at 45 Days after sowing], quality [oil content (51 %), oil yield (321 kg ha-1) and protein content (22.2 %)] and economics [gross returns (50480 Rs.), net returns (34470 Rs.) and B:C Ratio (3.15)] of sesame over application of RDF alone. Among sulphur levels application of 30 kg sulphur ha-1 recorded highest physiological growth [Leaf area index (1.89), crop growth rate (8.49 g m-2 day-1), relative growth rate (0.051 g g-1 day-1)], quality [oil content (51%), oil yield (319 kg ha-1) and protein content (22.2)] and economics [gross returns (50080 Rs.), net returns (35020 Rs.) and B:C Ratio (3.32)]of sesame over application of sulphur @ 10 and 20 kg ha-1.
