The aim of this study was to conduct a comparative study, on the productivity of hybrid and open-pollinated maize, of farmers in Giwa Local Government Area (LGA) of Kaduna state. Precisely, using structured questionnaire through purposive and random sampling, it evaluated current hybrid and open-pollinated maize production technologies by; describing the farmers' major socio-economic characteristics and most importantly identifying the economic difference between hybrid and open-pollinated maize, using the farm survey data collected from 160 maize farmers in October- December 2009 for the cropping year 2009-10. The cob-douglas production function model was best and the numbers of significant variables were four for hybrid maize production namely farm-size (land); seeds; labour and fertilizer. Open-pollinated maize production on the other hand, also has four significance variables namely farm size (land); labour, fertilizer and insecticides. Z-test was used to test the profitability of hybrid maize versus open-pollinated maize and the result revealed that hybrid maize production was more profitable and the difference was statistically significant at 1% level of significance.

 The result of analysis of resource use efficiency of hybrid and open-pollinated maize shows that the ratios were not equal to one. The ratio indicates that sampled farmers underutilized fertilizer and insecticides. The efficiency ratio for seeds, labour and herbicides were less than one showing that the sampled farmers over-utilized seeds, labour and herbicides on the farms. This study recommends that credit facility particularly the procedure for loan should be made simple to improve hybrid and open-pollinated maize production in the study area
