Logistic regression models were used to predict the socioeconomic factors influencing the levels of knowledge in the use of manure, fertilizers and manure + fertilizers. Age of the household head (HHH), training in the use of animal manure and group membership significantly influenced household levels of knowledge in use of animal manure. Group membership, age of the HHH and total farm size significantly influenced the levels of knowledge in inorganic fertilizers. Gender of the HHH, household size, training on manure + fertilizers, group membership and total farm size significantly influenced the levels of knowledge in use of manure + fertilizers at P<0.05. The implication of these results is that in order to improve knowledge levels, trainings should be enhanced and targeted to the farmers belonging to farmer groups considering their gender, age and total farms size.enGroup membershipAnimal manureInorganic fertilizersTrainingFarmersArticle
