Grain Quality, Nutrient use Efficiency, and Bioeconomics of Maize under Different Sowing Methods and NPK Levels

Finding more efficient ways to fertilize crops will reduce N losses and increase nutrient uptake. A field experiment was conducted at the Agronomic Research Farm, University of Agriculture, Faisalabad, Pakistan, during 2006 and repeated in 2007. The crop was planted in three different geometrical ar...

A field experiment was conducted at the Agronomic Research Farm, University of Agriculture, Faisalabad, Pakistan, during 2006 and repeated in 2007. The crop was planted in three different geometrical arrangements, viz. flat sowing (rows spaced 75 cm), ridge sowing (ridges spaced 75 cm), and strip planting (double row strips spaced 120 cm with 30 cm between rows in a strip); NPK was applied in four different combinations (0-0-0 control, 200-100-100 low dose,250-125-125 medium dose, and 300-150-150 high dose kg ha-1). Both fertilizer use efficiency (FUE) and N use efficiency (NUE) were significantly lower with the high fertilizer dose (300-150-150 kg NPK ha-1) than with the low or medium doses. The highest nitrogen uptake efficiency was with the medium fertilizer dose and proved to be a good indicator of grain yield. Among planting methods, ridge plantation resulted in higher FUE, NUE, and N uptake efficiency. The highest grain yield, net income, and benefit cost ratio were recorded when a crop was planted on ridges with the medium fertilizer dose. Sowing methods did not significantly affect grain quality parameters. Seed oil, protein, and starch contents were the lowest in the control.
