The main objectives of the study were to examine and identify the factors that affect agricultural productivity in Imo State, Nigeria. The method of proportionate random sampling technique was used in selecting a sample of 99 farmers who were interviewed using validated, structured questionnaire. Primary data collected were analyzed using frequencies, means, and the Ordinary Least Squares multiple regression analysis technique. The results of the analysis show that the marginal value products estimated for farmland, planting materials, chemical fertilizer and labour are 0.0654, 0.0615, 0.0871 and 0.0831 respectively. Yam/cassava/maize/vegetable/melon combination was identified as the main crop combination practiced by the farmers in the state. Analysis of resource use efficiency shows that the farmers are highly efficient in the use of planting materials but highly inefficient in the use of land and chemical fertilizer. The results of the multiple linear regression analysis on the determinants of agricultural productivity show that age, level of education, years of farming experience, farm size, extension contact, fertilizer use, planting materials and labour use are the main determinants of agricultural productivity in the state. It is recommended that extension agents should teach farmers to use the right quality and

Profitability of rice production in different production systems in Ebonyi State, Nigeria was evaluated. Rice is critical for food security in Nigeria, hence, farmers need to make appropriate choices of rice production systems to optimize production and ensure an adequate domestic supply. This study used 2015 survey data from rice farming households. Rice farmers in swamp, lowland and upland rice production systems showed variability in profit. Swamp production systems had the highest return per hectare (29.37%) followed by lowland production systems (20.10%) and upland production systems (13.03%). Poor access to production credit and climate change were constraints to rice production in the area. Rice production using the swamp production system is profitable and would ensure increased production and higher returns to the farmers. It is recommended that farmers should form cooperative groups to enable them to pool resources together to boost their production.
