CARACTERIZAÇÃO AGRONÔMICA DE GERGELIM (CULTIVAR K3) EM DIFERENTES ÉPOCAS DE SEMEADURA E DENSIDADE DE PLANTAS

Abstract

Sesame cultivation in Brazil has gained prominence in the increase of cultivated areas, especially in areas of the cerrado, where it is limited in relation to the production of other crops due to climatic conditions. Therefore, the expansion of this crop in Brazil depends on technical and scientific advances, especially in relation to management. Considering the importance of sesame for Brazilian agriculture and the need to increase the productivity and profitability of the crop, this study aimed to evaluate the effect of different sowing times and plant densities on the production of sesame (cultivar K3). The experiment was conducted at the Experimental Field of Annual Crops of the IF Goiano Campus Hidrolândia. Two sowing times were tested, with an interval of 7 days between them and two plant densities (7 and 14) per linear meter. The design used was a 2x2 factorial, distributed in randomized blocks, with 4 blocks of 4 plots, where the following variables were evaluated: plant height, number of capsules per plant and productivity. The results obtained indicated that there was no significant difference between the sowing dates and plant densities evaluated for any of the variables analyzed.
