Abstract

Flood irrigation and broadcast application of nitrogenous fertilizers for wheat is wastage of precious inputs, promoter of weed infestations and major causes of low yields in Pakistan. For this hypothesis, controlled irrigation (60, 70 and 80% MAD-Management Allowed Depletion), nitrogen applications (broadcast and placement with 60, 90 and 120 kg urea ha-1), and seed priming (control, hydro priming and seed priming with 100 g Poly Ethylene Glycol per liter of water) were tested on wheat variety Pir-Sabak 2015 at Charsadda, Swabi and Kohat of Khyber Pakhtunkhwa-Pakistan during 2017-19. Wheat yield parameters were positively correlated with controlled irrigation, placement nitrogen application and seed priming. Emergence, grains per spike, grains weight, spikes per m2, grain yield, leaf area, specific leaf area, leaf area ratio and crop growth rate were highest for.70% MAD irrigation, placement application of 90 kg urea per hectare and seed priming (hydro and osmo priming). Yield parameters of wheat were declined with either 60 and 80% MAD, broadcast urea application and null seed priming.
