Gross Margin Analysis of Using Neem Seed Extract to Control Cowpea Pest at Bida-Nigeria


Investigations were carried out to evaluate the profitability of an alternative method of pest control - neem seed extract (NSE) at Bida (9.06N and 5.59E) during the 1994 and 1995 cropping seasons. The results obtained were compared with the performance of a conventional agrochemical-nuvacron. Results obtained show that there were significant difference between the yields obtained from the two control methods at 5% level of significance. Also 3.33% w/v of NSE and 0.2% v/v of nuvacron gave best yields of 712.60 kg/ha and 1165 kg/ha respectively. These results translate to gross margin of N10,993.19 and N19,637.99 respectively. It is recommended that each farm family should own at least one neem tree.
