Effects of Climate on Growth and Yield of Rice (Oriza Sativa) in Yola

This research was designed to examine the effect of climate on rice growth and yield in Greater Yola. The study was conducted in a research farm located in Sangere, Greater Yola, Adamawa State. Experimental farm was designed base on Randomized Complete Block Designed (RCBD) system. Three selected varieties of rice; Nerica L20, Faro 44 and ITA 206 were planted and replicated three times and measurement was taken on them. Daily climatic data were collected from Modibbo Adama University of Technology Meteorological Station. Climatic pattern in the study area during the growing period indicated that highest rainfall was recorded in the month of August and decreases toward October. Relative Humidity showed a direct relationship with rainfall, while the remaining climatic elements showed inverse relationship with Rainfall and Relative humidity. Variation in growth of rice revealed that there is a variation in plant Height and Leave length at P= 0.05, but no variation in culm diameter. While, Variation in yield parameters of rice indicated that only yield per plot and weight of grain(g) are highly significant at P= 0.01 and that Nerica L20 has the highest yield per plot than others.
