Four treatments were implemented: Factor A, mineral fertilizer with (1) recommended fertilizer (NPK); (2) no fertilizer (Zero), combined with Factor B, Gliricidia green manure, with (G YES) or without (G NO), respectively. This categorization was based on the history of using green manure for last 5 years at a recommended rate of 2 tonnes ha−1 year−1, obtained through a preliminary survey prior to the on farm trials. The plot sizes were 20 m × 10 m in Fields, divided into 4 subplots of 5 m × 10 m; in Homegardens 10 m × 10 m plots were divided into 4 subplots of 5 m × 5 m.
