Effect of urea and sulphur coated urea on wheat and maize yield in Afghanistan

Effect of urea and sulphur coated urea on wheat and maize yield in Afghanistan

Agrokemia es Talajtan 24(1/2): 17-22

In field trials, maize Dekalb XT 218 and wheat Kenya 227 were given 50-150 kg N/ha as urea or S-coated urea (SCU). Fertilizer was applied in single or split dressings. In wheat, urea was always more effective than SCU and the highest yield was given by 100 kg/ha applied in 2 split dressings. Split application did not improve efficiency of SCU. With maize, SCU gave the best result, also at the 100 kg/ha rate.
