Effect of planting methods and planting density on growth and yield of sesame in non-saline area of Patuakahali, Bangladesh

The planting methods and planting density influence the growth and yield of crops. A field experiment was conducted with split-plot design using two planting methods (row and broadcast) and four planting densities (40, 50, 60, and 70 plants m^-2) to observe the effect on yield and yield attributing characters of sesame in the field laboratory of Agronomy Department in Patuakhali Science and Technology University. The yield and yield components were significantly affected by planting methods. The row planting method showed higher yield and yield components than the broadcasting method. The yield and yield components were also affected by planting density. The plant height, the number of branches plant^-1, the number of capsule plant^-1, and 1000 seed weight were reduced with the increase of planting density except for yield. The highest yield (1358.0 kg ha^-1) was obtained from 60 plants m^-2 in the row planting method. Row planting method with 60 plants m^-2 could be recommended for better yield of sesame.
