Estimates of post-harvest losses of rice during storage by smallholder rice farmers was carried out in Benue State Nigeria, with the following objectives, identifying the demographic features of the respondents, estimating post harvest losses using different storage techniques and determining factors influencing post harvest losses during storage. Cluster, purposive and simple random sampling Methods were used in collecting samples, 288 respondents through questionnaires. Data analysis was done using Means, percentages, frequency counts and OLS. Results revealed that, mean age was 41 years, males were 63%, while 56% of those interviewed were married, mean size of family was 8 persons, mean size of farm cultivated was1.6 hectares, mean number of years spent in schooling was 5 years and mean years of farming rice was 10. Local /Traditional storage techniques recorded the highest losses 58.78 %, semi modern storage techniques recorded 39.99% and the modern storage techniques recorded 1.23%.The result of OLS revealed that, R2 was 0.45%. Five factors were significant, and their coefficients conformed to econometric criteria. Types of rice storage techniques used, education and experience were significantly negative at 1% , meaning, decrease in these factors leads to increase in the dependent factor by the size of their coefficients -0.79, -0.40 and -0.27. While the quantity of rice stored and duration of storage were significant at 1% and positive implying, increase in these factors leads to increase in the value of the dependent factor by the magnitude of their coefficients 0.21 and 0.49. The following recommendations have been made; rice farmers should be given training and also provided with amenities that will aid in managing post-harvest losses of rice on their farms in the study area.
