Timing and Rate of Phosphorus Application Influence Maize Phenology, Yield and Profitability in Northwest Pakistan

Phosphorus (P) is the second most important crop nutrient after nitrogen that increases productivity and profitability of maize (Zea mays L.) on P deficient soils in Northwest Pakistan. The objective of this study was to find the best level and time of P application for higher maize (cv. Azam) productivity and profitability. Field experiment was conducted at the Research Farm of Khyber Pakhtunk...

Effect of the timing of nitrogen fertilizer application on grain yield and quality of bread wheat (Triticum aestivum L.) cultivars under terminal drought stress conditions

To investigate the effect of  the timing of nitrogen fertilizer application on grain yield and quality of bread wheat cultivars under terminal drought stress conditions, two field experiments were conducted at Agricultural Research Station of Miandoab in West Azerbaijan, Iran, in 2013-2014 and 2014-2015 cropping seasons. Experimental treatments were arranged as split plot factorial in randomiz...
