Effects of Climate on Growth of Rice (Oriza Sativa) in Greater Yola
This work was design when there is a need to investigate the effect of climate on growth of different varieties of rice in Greater Yola. The study was conducted in a research farm located in Sangere FUTY, Greater Yola, Adamawa State during the 2014 rainy season (3rd June – 7th October 2014). 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. Correlation result showed that, rainfall has a positive relationship with rice at all the developmental stages, it is positive at P= 0.05 in vegetative stage and at P= 0.01 in Reproductive and ripening stage.
