    ASSESSMENT OF TEMPERATURE AND RAINFALL VARIABILITY ON MELON PRODUCTION IN NASARAWA STATE, NIGERIA
    (DEPARTMENT OF PHYSICS FACULTY OF NATURAL AND APPLIED SCIENCES NASARAWA STATE UNIVERSITY, KEFFI NIGERIA, 2018-03-22) Kachalla, Abba
    Melon is an environmental tolerant crop which is produced massively in Nasarawa State. The study is aim at examining the Assessment of temperature and rainfall variability on melon production (output). Temperature and rainfall are two factors, among others, that Assessment the production of melon in Nasarawa State. Data were obtained from secondary sources; melon production data was obtained from Nasarawa State Agricultural Development Programme whereas temperature and rainfall data were obtained from NIMET. The Walter’s method, as modified by Olaniran, was used to calculate the onset and cessation dates of rainfall and temperature. Multiple regression was used to test the hypothesis using standardized time series of melon production, temperature and rainfall. Descriptive statistics was used to represent results in charts, graphs at 95%level of significance. The state has a mean temperature that ranges from 26-28°C and annual rainfall between 1100-1700mm with onset in April and cessation in October. Temperature is on the increase whereas rainfall is on the decrease, although it is statistically not significant at 95% level. Onset and cessation dates do not Assessment melon production, as result show that these dates are not significant in melon production. Temperature has little Assessment on melon production when compared to rainfall. They both constitute 24% Assessment on melon production. Melon requires between 200-230mm of rainfall and 26-28°C of temperature. A weak relationship was observed using multiple regression analysis, having an r-square value of 0.239. It is recommended that agrometeorologists/climatologists should extend their weather forecast to melon farmers, intensification of irrigation farming to burst melon production and also developing of melon resilient seed that can withstand climate variability and change.
