Abstract

The plant density can influence the growth, development, and productivity of sesame. The objective was to evaluate the effect of different planting densities of black sesame on its agronomic parameters. The study was conducted during the period 2020-2021, in the locality of Monte Grande, San Pedro del Paraná, Itapúa-Paraguay. The treatments were: (D50) with 50.000; (D75) 75.000; (D100) 100.000; (D125) 125.000; (D150) 150.000; and (D175) 175.000 plants ha-1 respectively, arranged in a randomized complete block design, with four replications. Plant height, number of branches plant-1, capsules plant-1, grains capsule-1, thousand grain weight, and grain yield were evaluated. The results were subjected to Analysis of Variance (ANOVA) and compared by Tukey's test at a 5% probability of error. Planting density significantly influenced the number of branches plant-1, capsules plant-1, thousand grain weight, and grain yield. Treatment D50 obtained the highest number of branches plant-1 (3,2 units), capsules plant-1 (124,2 units), and thousand grain weight (2,8 g). However, treatment D100 showed the highest grain yield (1.079 kg ha-1). The most suitable planting density for black sesame was 100.000 plants ha-1, for the soil and climatic conditions of the Southern Region of the country.
