Effect of sulphur and bio fertilizers on sesame (Sesamum indicum L.) yield and quality in red and lateritic soils of West Bengal, India

Abstract

A field experiment was conducted on sesame during pre-kharif season to study the effect of combined application of sulphur and biofertilizers on yield attributes of sesame (Sesamum indicum L) and its quality. The experiment was laid out in randomized block design with three replicants and thirteen treatments. Result of the study showed highest grain yield (8.13 q ha 1), stover yield (19.57 q ha-1), bilogical yield (27.55 q ha-1) and harvesting index (29.41) of sesame was registered where higher dose of sulphur along with combined application of PSB and Azotobacter viz. S @ 45 kg ha-1 + PSB + Azotobacter. The highest crude protein content and protein yield in seed of sesame (kg q-1) was recorded due to higher application of sulphur along with combined application of PSB and Azotobacter viz. S @ 45 kg ha-1 + PSB + Azotobacter. The study conclude higher yield and better quality of yield in sesame resulted from application of sulphur @ 45 kg ha-1 + PSB + Azotobacter which leads to overall profit to the farmers. Thus study recommended for integrated use of biofertilizers and chemical fertilizers in sesame cultivation in red and lateritic belt of West Bengal and other part of country where ever the soil of this kind is available.
