Abstract

On farm verification trial of soil test based crop response phosphorus calibration study on bread Wheat was conducted at Degam district of North Shewa zone during 2019 cropping season using optimum amount of nitrogen (92kgN/ha), critical P-value (22ppm) and Phosphorus requirement factor (5.85) determined during soil test based crop response phosphorus calibration study. Using the determined value of P critical concentration and phosphorus requirement factor, this study was initiated to verify P critical value and P requirement factor for bread wheat. Three treatments were included in the experiments as: control (without fertilizer (T1), (blanket recommendation= (100:100kg/ha Urea and DAP) (T2) and soil test based crop response phosphorus recommendation (T3). The activity was conducted across seven farmers’ and those farmers were used as replications with RCBD design. The plot size was 10m*10m for each treatment. Soil data were collected on Soil pH and available phosphorus which ranges 56 - 5.72 and 9.71- 20.66 respectively; agronomic data were collected on plant height and grain yield. The highest plant height and grain yield were obtained from STBCR 95.03 cm and 2996.43 kg/ha correspondingly. To estimate the economical significant of the different fertilizer rates, partial budget analysis (CIMMYT, 1988) was employed to calculate the Marginal rate of return (MRR) to investigate the economic feasibility of treatments. Based on this, the Marginal Rate of Return (MRR) were found to be 150.81% for soil test based fertilizer rate and 134.7% for farmer practice (blanket recommendation). The economic analysis revealed that the highest net income (56202 ETB) was gained from soil test based P-fertilizer recommended treatments with marginal rate of return (150.81%) which is superior than the minimum rate of return (MRR) 100%. Therefore, based on the result obtained from this trial soil test based fertilizer recommendation is recommended for the study area. furthermore, further studies should be needed since the soil is heterogeneous and changed in short period of time.
