Abstract
Using a nationwide survey of rice growing farmers in Uganda, this study examined how farmers grow
rice under rainfed conditions in various agro-climatic zones, and how rainfed rice cultivation performs
in terms of yield, and what factors determine the level of rice yield. The study found that Nerica 4 and
Supa were the two major varieties planted by rainfed rice farmers, the former in upland and the latter in
lowland. High seeding rate, low fertilizer-chemical application and high labor intensity characterized
rainfed rice cultivation in Uganda, though distinct regionality existed in fertilize-chemical application
and labor intensity. The high marketed ratio of rice produce also characterized rice farming. The
estimation of yield functions revealed that rainfall, the amount of seeds and fertilizers applied, lowland
and small farmers were positive determinants of rice yield per hectare, that the potential for high yield
existed in western regions of the country, and that there were some minor lowland rice varieties that
performed better than popular Nerica 4 and Supa. The estimation also revealed that rice plots under the
traditional tenure systems yield less, and those under the leasehold system yield more, than those
under the formalized freehold and private mailo systems.
