Effect of Planting Methods in Different Sesame (Sesamum indicum L.) Varieties during the Summer Season

Abstract

A field experiment was conducted during the summer seasons (2^nd week of March to 3^rd week of June) of 2019 and 2020 at the District Seed Farm, ‘AB’ block, Kalyani at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India to evaluate the effect of line sowing and broadcasting methods of different varieties of sesame for good growth and yield. The experiment was laid down in 2×8 factorial RBD with replicated three times having two methods of sowing viz. S₁: Line sowing; S₂: Broadcasting was in the main block and eight varieties viz. V₁: GT₁; V₂: GT₂; V₃: GT₃; V₄: GT₄; V₅: GT₅; V₆: GT₆; V₇: GT₁₀; V₈: Savitri was in the sub-block. Results revealed that plant height, rooting depth and root mass were considerably influenced by sowing methods and higher value was found under line sowing. Plant establishment methods did not vary a number of primary branches plant^-1, LAI, CGR and dry matter production significantly but varied among varieties. Maximum number of capsule plant^-1 was found under line sowing and the highest value was recorded in the variety GT₄. Line sowing responded more yield a tune of 8.26% as compared to broadcasting. Oil content in the 43–47% range was registered under different varieties and the highest (47.7%) was recorded in the variety V₅. Under line sowing protein content was found maximum with the variety V₄. A higher benefit-cost ratio (1.82) was noted under the broadcasting method compared to line sowing (1.76).
