Effect of sulphur and organics on yield and sulphur use efficiency in sesame

摘要

Investigations were carried out during seasons of summer and kharif 2001 to study the effect of sulphur at varying doses viz., 0. 15, 30 and 45 kg ha~(-1) and different organics viz., farmyard manure, poultry manure and sulphitation pressmud each applied at 101 ha~(-1) on yield and sulphur use efficiency of sesame (Sesamum indicum L ) cv. TMV 3. The seed and stover yield progressively increased with S levels. While response ratio, apparent S recover} and agronomic efficiency except physiological efficiency were decreased with increased S levels. Seed yield increased with application of S levels and 45 kg S ha~(-1) registered maximum seed yield (870.2 and 898.1 kg ha~(-1))- But SUE was maximum with S @ 45 kg ha~(-1). Poultry manure @ 101 ha~(-1) recorded the highest seed yield (777.4 and 801 8) and sulphur use efficiency.
