Abstract: The study on determinants for application of organic manure in maize production was conducted at Kale village Rukwa region. The objectives of the study were to identify thefactors for application of organic manure in maize production in the study area, determine the level of community awareness on the importance of applying organic manure in maize production and examine economic factors influencing application of organic manure. A sample of 75 respondents was used. Multiple linear regression analysis models were used to test the linear relationship of independent variables. Application of organic manure as a dependent variable was tested if it had relationship with traditional experiences on organic manure, community norms on application of organic manure, beliefs towards application of organic manure, and grazing practices. Descriptive statistics were also used for analysis. Results for t- test indicated that low application of organic manure was associated with traditional experiences on organic manure (t = 9.18, P < 0.001), norms of the community on application of organic manure (t = 9.97, P < 0.01), beliefs towards application of organic manure (t = 7.25, P < 0.05) and grazing practices (t = 4.27, P < 0.05)
