Impact of Some Foliar Applications on The Yield and its Components of Some Pea Cultivars and their Tolerance to Infestation by Main Insect Pests

Abstract

The present work was carried out during the 2021/2022 and 2022/2023 seasons at The Experimental Farm of Shandweel Agricultural Research Station, Sohag Governorate, Egypt to evaluate the effects of foliar spray applications with abscisic acid, salicylic acid and chitosan on some vegetative and yield characteristics of four pea cultivars and their susceptibility to infestations by each of aphid, thrips, and leafminer. Data revealed that the foliar spray application enhanced all vegetative and yield characteristics, however, the infestations with the three studied insect pests decreased significantly compared to the control. It is clear that the differences between the four pea cultivars and between the four foliar spray applications were significant in both seasons of the study, also, the interaction between them was significant in both seasons. In almost, salicylic acid was the best foliar spray application in regard to pea production and insect pest control. On the other hand, pea cultivars varied in their response to the foliar spray application with the previous materials and they need more studies.
