Effects of planting time on the growth and yield of chili (Capsicum annuum L.)

Abstract

Fourteen genotypes of chili (Capsicum annuum L.) from diverse sources were evaluated to determine the most suitable genotypes and planting time among the selected genotypes. The genotypes sown at two different times showed distinct differences across all fifteen quantitative measures. November-sown genotypes showed comparatively better results for all the quantitative traits except the days to 1st germination, plant height, number of primary branches, number of secondary branches and number of flowers per plant. Maximum fruit weight per plant was observed in BARI-I (376.02 gm) and Jhilik (377.37 gm), which were sown in October and November, respectively. Among the October-sown genotypes, BARI-I recorded the highest fruit yield (18.80 ton/ha) followed by Jhilik (16.17 ton/ha) and Morich King (13.73 ton/ha), while among the November-sown genotypes, Jhilik (18.87 ton/ha) showed the foremost result, followed by Morich King (13.79 ton/ha), BARI-I (13.67 ton/ha) and Bullet 303 (11.06 ton/ha). The findings demonstrated that the genotypes differed significantly in most traits in both seasons, offering a good opportunity to select appropriate genotypes for each season for commercial purposes.
