Pakistani soils are very poor in organic matter content; therefore, fertility status of soils is very low. Farmers apply fertilizer but below the recommended doses. As we know that for the better quality and yield of crops, time and method of fertilizers application are the most important factors. Some growth stages are very sensitive, at those stages of growth; the addition of fertilizers is more responsive than others. In order to nutrients to become available when the plant needs them and to make maximum benefits, fertilizers should be applied at the right time. In this experiment, impact of fertilizer applying methods for nitrogen and potash at different times was investigated on wheat crop. Wheat was sown as a test crop with six different fertilizer application methods at varying times under RCBD arrangement with three replications. The experimental soil was high in pH, low in fertility status and free from salinity and sodicity hazards. Wheat grains were analyzed for mineral contents. The results revealed that maximum grain yield was obtained from treatment T6 (Half N at sowing time + spray of 2% N after 30 & 45 DAS + half K at sowing time + spray of 2% K after 30 & 45 DAS) as compared to other treatments. Furthermore, the chemical analysis showed the maximum quantity of N, P and K in wheat grains obtained from T6. This study concluded that split application of fertilizer at various stages of wheat crop produced better yield as well as wheat quality. The joined addition of NPK at sowing time along with 2% spray of N and K after 30 and 45 days of sowing is the best approach for the increase in wheat growth and yield.
