Popis: |
Rice is a major crop in the irrigated areas of the valley of the River Niger. Rice growers use urea and NPK on this crop. To help improve knowledge on soil fertility, fertilizer quality, and practices related to their use, a study was conducted in the irrigated areas of Saga, Karma, Sebery and Gaya. Thus, the variety of rice Kogoni 91-1 (Gambiaka) was used on hydromorphic to pseudo-gley soils in the rainy season 2014 and the dry season 2015. The experimental design was a randomized complete block with five treatments: T0 = N122P30K30 (peasant Practice); T1 = N138P90K60; T2 = N175 P112 K60; T3 = N100P120K50S20Zn2; T4 = N122P30K30S20Zn2. The comparison of averages shows that the highest average yield was achieved with the formula T4 (N122P30K30S20Zn2). Yields vary from 3.6 t/ha at Sebery to 7.2 t/ha in Gaya during the rainy season of 2014. The same trend was observed in the dry season of 2015 when the T4 yielded about 11 t/ha in Sebery. |
