| Popis: | Smallholder farmers are reluctant to risk investing in fertilizers. To understand how risk is perceived and how economic returns are distributed before the decision to invest in fertilizer use is made, needs a systematic approach using localized applications. This study assesses the profitability and net return variability of fertilizer micro-dosing (MD) in the sub-humid rain-fed maize (Zea mays L.) farming system in Tanzania. Useful data was gathered from a household baseline survey, water and nutrient limited calibrated yields, marginal costs and yields from farmers’ field trials, along with other information from expert and historical data. Crop yields, crop prices and prices for key production inputs (mainly fertilizer) were simulated for the net economic return distributions for maize under different fertilizer MD rates using the Economic and Nutritional Impact Assessment Model (FARMSIM), which is supported by Simulation and Econometrics to Analyse Risk (SIMETAR). The results show relative difference... |
