Abstract
Study was realized on July 2021, inside of the Institute of Agricultural Research for Development (IRAD). Main objective of study is to determine the dose of mineral fertilizers and densities which responses well to the rice culture especially of the variety Nerica L36 in a humid area of the valley of Benoué. Treatments are constituted of fourth levels of doses and repeated 3 times: T1 (0 kg NPKSB+100 Kg Urea/ha); T2 (150 kg NPKSB+100 Kg Urea/ha); T3 (200 kg NPKSB+100 Kg Urea/ha; T4 (250 kg NPKSB+100 Kg Urea/ha). Three densities were considered: De1=20 cm x 20 cm; De2=25cm x 25cm; De3=30 cm x 30 cm. Experimental design was a split-plot, with two factors: Factor 1 concerning dose of fertilizers and Factor 2 concerning variety of Rice (Nerica L36). Evaluation parameters were: the height of plant, the number of tillers, the number of panicles/plants, panicles length, heading date at 80 % and maturity date.
