ABSTRACT

This study examined the effect of various nitrogen fertilizers in kilograms: 0kg, 30kg, 60kg, and 120kg on varieties of rice: NERICA L-19; NERICA L-20; NERICA L-41; NERICA L-42; and NERICA L-60 from the department of plant physiology and crop production in the college of plant science and crop production Federal University of Agriculture Abeokuta (FUNAAB), Ogun State Nigeria. Also, to determine the appropriate fertilizer at different levels and the best variety for optimum yield of rice and to compare the treatment means for each of the crop varieties. Analysis of Variance technique was used to investigate the effect of various kilograms of nitrogen fertilizers on the yield of the five different types of NERICA rice. The findings revealed that at all the levels of nitrogen fertilizers applied, 30kg of nitrogen fertilizer gave the optimum yield. Further to that, the study discovered that different levels of the nitrogen fertilizers applied did not significantly influence the tons of NERICA rice produced, that is the yield of rice in tons is independent of kilograms of nitrogen fertilizers applied. NERICA L-42 of rice is therefore recommended to farmers to be planted with 30kg of nitrogen fertilizers.
