Comparative Study of Field Performance and Economic Analysis of Sweet Corn Production under Subsistence Irrigation Methods at Maiduguri Sudan Region of Nigeria

Abstract

This study was carried out to determine both the profitability and yield of sweet corn produced under three subsistence irrigation methods (Watering can, Pitcher and bucket drip in the production of vegetable) sweet corn. The result show that number of days to 50% silking in sweet corn was significantly (P<0.05) reduced by pitcher and bucket kit drip irrigation method. Fresh cob weight was lowest with watering can, while with pitcher (1009Kg/acre). and bucket (1006Kg/acre). Weed biomass yield was significantly (P<0.05) reduced by irrigation method, Pitcher and drip were observed to be similar in yield of weed biomass. The weed incidence was highest with the use of watering can. Total fixed cost was N1,758.6, N1,380.6 and N2,875 respectively for watering can, Pitcher and drip irrigation. Watering can has the highest variable cost of N28,758. This was followed by pitcher (N28,435) and the lowest was drip with N27,492. The net farm income were N19,841.40, N21,940.40 and N22,907.40 respectively for watering can, pitchers and drip method. It was thus concluded that bucket drip kit is more economical/profitable even through the agronomic yield was equal to that of pitcher irrigation.
