| Abstract | ||
Field experiments were carried out at Experimental Farm of the Desert Research Center, El-Kharga Oasis, New Valley Governorate, during the two consecutive seasons of 2019/ 2020 and 2020/ 2021. The experiments were conducted to study the effect of application of super absorbent polymer (SAP) (0, 30, 60, and 90 kg fed-1and foliar spraying with fulvic acid (FA) at (0, 2, 4, and 6 g L-1) on yield and yield components and grain chemical composition onwheat (Triticum aestivumL.)cv. (Misr - 2). under sandy soil conditions. Results showed that yield as well as the components and quality traits of wheat were significantly affected by SAP in both seasons. The highest value of these traits was obtained with using the highest rate of SAP, 90 kg fed-1. Increasing the levels of FA from 0 to 6 g L-1caused significant increases in all studied wheat traits during both seasons. The highest yield and its components were obtained with 4 g L-1and the lowest were with control treatment of FA in both seasons. The highest values of these traits i.e. nitrogen, phosphorous, potassium, protein, and carbohydrates were obtained with FA (6 g L-1), while the lowest was with control treatment in both seasons. Raising SAP and FA levels up to 90 kg fed-1and 6 g L-1led to a significant increase in all studied parameters in both seasons. | ||
