This study was conducted to assess factors influencing rice production in the Lwafi-Katongolo Irrigation Scheme. A sample of 120 farmers from 4 villages of Katongolo, Masolo, Kamwanda and Mpata were purposively selected for the assessment of factors influencing crop yields and water delivery (flow). Data was collected through a questionnaire administered to households to generate information on factors influencing water delivery and how the influence affects rice production. The data were subjected to analysis of trends in crop production and water flows using Microsoft Excel. Multivariate regression analysis was used to assess factors influencing production during the wet and dry seasons while Descriptive analysis was used to determine the level of farmer satisfaction on irrigation services. Qualitative data were analyzed by content analysis. The findings show that Cropped land size, condition of secondary canals, relative position of irrigated area and Government facilitation for maintenance significantly and positively influenced productivity in the scheme. Experience of farmers in irrigation practices influenced negatively the productivity in the scheme. The annual rainfall increased 1.58mm in the period 1981-2020 causing destruction of canal walls and soil erosion in the scheme. Water discharge in the irrigation scheme decreased by 40.36m3/s between 2019 and 2021 implying poor water supply hence negatively influencing productivity. The finding also explained farmers satisfaction for water delivery in the scheme as the response was 61.57% Neutral, 33.75% Dissatisfied, 3.64% Satisfied, 1.04 Strong Dissatisfied and 0% Strong Satisfied. The study recommends, the government and other stake holder of agriculture should continue planning for rehabilitating the infrastructure destructed and constructing other structure as per design, construction of water dam, and rescheduling of the maintenance and operation for Water user association in the scheme.
