Nutrient Management of Shallot Farming in Sandy Loam Soil in Tegalrejo, Gunungkidul, Indonesia

The serious problems of sandy soils for crop development are low water-holding capacity, nutrient retention, and content all nutrients. objective the study was to increase soil evaluate types that mostly affect high shallot yield with reasonable economic values. field experiment conducted on upland loam soil. Six treatments consisting complete nutrients, N-, P-, K-, Mg- S-omission tests were arranged in a randomly completed block design four replicates. observed parameters included physicochemical properties, tissue content, growth, yield, input-output cultivation. results showed N, P, K, Mg S application successfully increased bulb, achieving 11.43 t ha−1 order K > N P~Mg S, where limiting factors, as revealed by significantly lower relative (varying from 79 88%). highest weight loss during storage occurred treatment (40 60%), indicating insufficient is most responsible quality shallot. gave income (7446.09 USD ha−1) revenue cost ratio 2.41 compared other treatments. tolerance limit price reductions do not cause losses 58.59%.
