ABSTRACT
In Côte d’Ivoire, the yield of different sorts of rice (Oryza sativa) remains below to their own potential productions. Insufficient production of rice recorded by farmers could be attributed to the no respect of cultural practice and inappropriate choice of different sorts of rice. To resolve this problem, the current study was undertaken with a main purpose to improve rice production. Thus, four varieties of rice including WITA 9 (V1) (control), 6444 GOLD (V2), TEJ GOLD (V3) and CY-2 (V4) were tested in four sowing spacing: 20 cm x 20 cm (S1), 20 cm x 25 cm (S2), 25 cm x 25 cm (S3) (control) and 25 cm x 30 cm (S4). Experimental design use in this study was constituted with three random blocks. From planting to harvest of rice seven parameters were collected and analyze statistically. Results of those analysis shown that the better value of yield and its components was recorded with variety CY-2 in the plots with sowing spacing (25 cm x 30 cm). Based on this result, some recommendations have been done to rice producers.
