| Abstract: | The experiment was designed in squaring and regressive rotation with thrcc factors ofsupplementary N, P, and K fertilizer in autumn, and five levels of each factor. According tothe data obtained a formula describing the relation between the yield and supplementaryfertilizer quantity was built through calculation with a computer. The analysis of 62 imita-tive agronomic schemes with the yield more than 2000 kg per mu indicated the highest yieldwas 2892.4kg per mu and its combination was "1.682, 1.682, 1" i. e. applying 58.5 kg ofurea, 117 kg of calcium superphosphate and 50 kg of potassium sulphate per mu. Theeffectiveness of nitrogenous fertilizer is also discussed. |
