Impact of Urea-Phosphate on Maize Development, Productivity and Nutrient Utilization in Field Trials

Abstract

Pakistan’s third largest crop after wheat and rice containing many essential mineral elements in grain which is referred as corn grain. The deficiency of these elements is major factor in country’s low corn yields. The current experiment was conducted to observe the effect of urea-phosphate on maize yield on pot study in field condition under the randomized complete block design in factorial arrangements using three replications. Among all the application method, fertigation application method exhibited the maximum results of all studied attributes like plant height (PH), leaves per plant (LPP), GY, BY, TGW, HI, CL, NGC, GLC, GR, transpiration rate, substomatal CO2, starch and protein contents at 75% recommended rate while all the traits mentioned poor performance at control (no urea-phosphate) and 50% recommended rate. This experiment showed that urea-phosphate proved to be more effective fertilizer for better maize yield and growth under different environmental conditions when applied through fertigation application method
