The partial budget analysis for sorghum farm in Sinai Peninsula, Egypt

Before changing from one production method to another, the farmer considers many factors, such as agro ecological requirements, availability of required additional production resources (labor, credit, skill, farmland, equipment, etc.), additional costs, and additional income resulting from the change, the research was interested to estimate the effect on net benefit of changing from one level of Nitrogen-fertilizer application to another (100, 200, and 300 kg N/Feddan), partial budget was used to assess the costs and benefits associated with a specific change in a sorghum farm, and partial budget is based on a unit so data were collected from one sorghum farm in Sahl El Tina. The results indicated that the marginal rate of return of changing from Treatment 1 (100 kg N/Feddan) to Treatment 2 (200 kg N/Feddan) was 9.61, and a changing from Treatment 2 (200 kg N/Feddan) to Treatment 3 (300 kg N/Feddan) gave marginal rate of return of 0.72, so Treatment 2 of (200 kg N/Feddan) was recommended.
