Pre-extension demonstration of soil test crop response based phosphorus fertilizer recommendation for maize was conducted in Chora district with the objective of participatory demonstration of this technology under farmers’ condition in 2019 cropping season. Two treatments were (T1) blanket recommendation and (T2) soil test crop response based recommended phosphorus fertilizer with improved maize (BH-661) variety. The trial was conducted on eleven farmers’ fields which were used as replications. Plot size for each treatment was 16m x 32m with the spacing of 50cm and 80cm between seeds and rows respectively using seed rate of 25 kg ha-1 and with recommended optimum N-fertilizer rate of 92 kg ha-1. In each PAs, one FREG unit comprising of 20 farmers were established. About 90 (66 male and 24 female) participants were take part on field visit based training held during physiological maturity of maize. The average grain yield obtained with soil test crop response based Recommended phosphorus fertilizer was 59.64 qt ha-1 while blanket recommendation was 44.59 qt ha-1 with yield advantage of 34% in the study area. Likewise, economic analysis result showed that net of return 28836.10 and 23811.00 ETB per hectare could be gained from soil test crop response based p-fertilizer recommendation and blanket recommendation respectively with MRR 125.47%. Therefore, soil test crop response based recommended phosphorus fertilizer should further scale up/out to reach more maize producer farmers in area.
