ABSTRACT

 Wheat is the major food crop of Pakistan. Newly developed wheat cultivar Pak-13 was evaluated by an assortment of seeding densities planted at NARC, Islamabad during the rabi season of 2014-15. The experiment was done under Randomized Complete Block Design and was replicated four times having six different seeding densities (SD1: 50, SD2: 75, SD3: 100, SD4: 125, SD5: 150 and SD6: 175 kg/ha) The analysis revealed that the highest chlorophyll contents (49.5), number of tillers/m (240), biological yield (7125 kg/ha), and grain yield (2660 kg/ha) were achieved at seeding density 100 kg/ha and was significantly different among various levels of seeding density. Again, the profitability analysis show the maximum gross margin (Rs. 98920/ha) and BCR (3.44) at 100 kg/ha seeding density level.
