Field trials were conducted for two years in 2007/2008 and 2008/2009 dry seasons at the Research Farm of National Horticultural Research Institute, Baguada in Kano State, to determine the effects of different organic manure in pepper/onion intercrops. The experiment consists of six (6) treatments using different organic manures viz: cow dung, sheep, poultry, goat, combined(combination of the four manures) and control. The experiment was arranged in a randomized complete block design (BCBD) with three replications, data on growth and yield were collected and analysed. The result shows that treatment with poultry manure resulted in significantly taller plants, more leaf production and higher yield. Atahe crops responded to poultry manure application better in both years and parameters such as plant height, number of leaves were increased significantly than other treatments.
