Impact of temperature and rainfall on soya bean production in Uganda, a case of Nwoya district in Northern Uganda

Abstract

Optimum rainfall and temperature can have a significantly increase yields of Soya beans. The study was conducted on the impact of temperature and rainfall on soya bean production in Nwoya district Northern Uganda. Rainfall and temperature data for a period 2009-2019 was obtained from the Uganda National Meteorological Authority while soybean data was obtained from the database of Nywoya district local government through the district production officer. The specific objectives included; to examine the trends in soya bean production, to examine the trends in rainfall and temperature and to examine the significance relationship between rainfall, temperature and soyabean production in Nwoya district. Results show no significance trend in soya bean production between (2009 - 2019). The study also found that rainfall and temperature have a significant effect on the production of Soya beans (0.002<0.05) at 5% level of significance and 0.032<0.05) at 5% level of significance respectively. The study recommend that good farming practices such as afforestation should be put into practice by most farmers in the study area. This could improve on ecology where trees planted could play a very important role in the rainfall cycle which leads to reliable rainfall and temperature distribution in study area.
