| Abstract: | Low phosphorus use efficiency (PUE) is one of the major reasons of poor wheat production worldwide. Among the various approaches used to enhance PUE, polymer coated fertilizers are relatively a new concept. Keeping this in view, a field study was conducted to evaluate polymer coated di-ammonium phosphate (DAP) to enhance growth, yield and PUE of wheat. Commercial DAP and polymer coated DAP (50%, 75% and 100% of recommended dose) were tested in wheat. Results revealed that application of 50% polymer coated DAP produced the same results or higher than 100% commercial DAP. However, the maximum increase in growth (plant height, root length, number of tillers m?2, inter-nodal distance), yield (number of grains per spike, 1000 grain weight, grain yield and biological yield) and phosphorus acquisition by wheat was observed with 100% polymer coated DAP. Moreover, 100% polymer coated DAP increased phosphorus recovery and agronomic efficiency compared to other treatments. |
