Performance of Sesame(Sesamumindicum L.) Varieties Under Varied Nutrient Levels

Abstract

The study was carried out to evaluate some sesame varieties under different nutrient levels for enhancing the productivity of sesame during March – June, 2014. The experiment was carried out in a split-plot design with three replications. The main -plot treatments had four nutrient levels viz., 75% of the recommended dose of fertilizer(RDF), 100% RDF, 125% of RDF, and 150% of RDF, and the sub - plot treatments included six sesame varieties viz., Laltil (Local), Atshira (Local), T6, BARI Til-3, BARI Til-4 and Binatil-2. RDF indicates a nutrient schedule of 56:72:23 kg N, P2O5, and K2O ha-1. The effect of nutrient levels, varieties, and their interaction showed significant variation in respect of yield contributing parameters, yield, and harvest index. Results revealed that in nutrient levels, 100% of RDF produced the highest seed yield (1223 kg ha-1). The least seed yield was observed with 150% of RDF (924 kg ha-1). Among the sesame varieties,BARI Til-4 showed the optimum growth and yield contributing parameters as a result highest seed yield (1170 kg ha-1). The lowest seed yield was obtained from Laltil (811.30 kg ha-1). The interaction effect was found significant where highest seed yield of 1481 kg ha-1 with 100% of RDF combination of sesame var.

Effect of different fertilizer doses on the yield of sesame in Charland

“…Charland soil does not exhibit waterlogging or excessive moisture stress. Farmers in Bangladesh's char regions often plant mungbean or sesame as a stand-alone crop or mixtures with rice, jute, peanuts, millets and sugarcane after the Rabi crops (Malek et al, 2021). Sesame may be grown in Bangladesh because of its favourable climatic and edaphic conditions.…”
