Effect of certain macronutrients foliar application on growth, yield and nutrientscontent of grains for two bread wheat varieties in sandy soil

摘要

This work carried out during successive winter seasons of 2009/2010 and 2010/2011 at Research and Production Station of National Research Centre, Al Nubaria district, Al Behaira Governorate, Egypt. The aim of this study is to investigate the effect of foliar feeding with Urea CO (NH2)2 and Monopotassium Phosphate (KH2PO4) on vegetative growth, yield, some of yield components and grain nutrients content of two bread wheat varieties (Triticum aestivum L.) i.e., Sakha 8 and Sakh 93. The present investigation conducted under new reclaimed sandy soil condition in a spilt plot arrangement with three replications. The results indicated that the foliar application of macronutrients caused a significant and/or highly significant effect on some of growth parameters and yield components during the two growing seasons. In addition, some nutrient of wheat grains content i.e. Potassium, Zinc, Manganese and Cupper were significant andor highly significant increased du to foliar application of macronutrients. There were significant differences between the two varieties for most studied characteristics. The interaction between the foliar application of macronutrients with the Sakha 8 variety gave the highest values of the main end product from grain and straw yield. The nutrient contents of wheat grains from Potassium, Calcium, Iron, Zinc, Manganese and Cupper were recorded highly significant effect by the interaction between macronutrients foliar application and wheat varieties
