Abstract

The present study was carried out under field conditions over two successive winter seasons of 2015/2016 and 2016/2017 on clay loam soil at the Experimental Farm at Shandaweel Agriculture Research Station, Sohag Governorate, Egypt. The aim of this research was to investigate effects of salicylic acid application in combination with foliar spraying with different rates of some microelements (Iron, Zinc and Manganese) on green and seed yield of some pea (Pisum sativum L.) cultivars. Under field conditions of this study, the interaction among Palmoral cv., 150 ppm of microelements and 300 ppm of salicylic acid concentrations produced the highest production of green pod yield (ton/fed.) and seed yield (kg/fed.) of pea. Furthermore, the application of interaction among Jaguar cv., 150 ppm of microelements and 300 ppm of salicylic acid concentrations gave the highest number of green pods per plant. The interaction among Master B cv., 150 ppm of microelements and 300 ppm of salicylic acid concentrations produced the tallest green pod (cm) and number of green seeds/green pod of pea over both experimental seasons. The highest values of the investigated yield and quality parameters were obtained by the interaction between 150 ppm of microelements and 300 ppm of salicylic acid in the first and second seasons. From results of this experiment, it could be concluded that application of adequate amounts of salicylic acid in combination with foliar application of microelements is one of the most important factors involved in improving yield and quality of pea plants and productivity.
