Abstract

This work was carried out during the two successive winter seasons of 2015/ 2016 and 2016/2017 under sandy soil conditions using drip irrigation system at El-Khattara Experimental Farm, Faculty of Agriculture, Zagazig University, Sharkia Governorate, Egypt, to study the effect of different native and modified egg white protein and total amino acids concentrations as foliar applications on growth, antioxidants, yield and seeds chemical constituent of pea cv. Master B. Foliar spraying of pea plants with native egg albumin (NEA) at 2 ml/l increased stem length, number of branches/ plant and total fresh weight/ plant in both seasons. Foliar spray with hydrolyzed methylated egg albumin (HMEA) at 2 ml/ l increased the concentration of chlorophyll a, b, and (a+b) and carotenoids compared to other treatments. Multi amino acids 24% (MAA) at 2 ml/ l increased N and total protein, MAA at 1 ml/l increased P(%) and HMEA at 2 ml/l increased K (%) in seeds in both seasons. NEA at 1.5 ml/ l or hydrolyzed native egg albumin (HNEA) at 1 ml/l increased number of green pod/plant, average green pod weight, yield of green pods/ plant and total yield/ green pod, whereas HMEA at 1.5 ml/ l or MAA at 1.5 ml l increased number of seeds/ pod.
