Abstract

A field experiments were conducted to evaluate the effects of green synthesis of zinc oxide nanoparticles (ZnO NPs), that prepared in the presence of date palm pits extract (DPPE) through two successive seasons 2018-2019 and 2019-2020 at Agricultural Experimental Research Station of Tag El-Ezz, Agriculture Research Center, Dakahlia Governorate, Egypt, to assay the response of pea plant (Pisum sativum L.) cv. Master-B cultivars to foliar spray by different zinc oxide nanoparticles concentrations (20, 40, 60, 80, 100, 200, 400, 500, 1000 mgl-1) compared with spraying with zinc sulfate 1000 mgl-1as control treatment. The field experiment was carried out in a randomized complete block design with three replicates. The results showed that plants spraying with nano zinc oxide with different concentrations gave various responses compared with those spraying with zinc sulfate. Spraying with 100 mgl-1 was significantly improved the growth attributes of pea plant through two seasons. While treating pea plants with 200 mgl-1 ZnO NPs improved weight of green pods per hectare and weight of 100 seeds during two seasons. Additionally, their positive stimulation for mineral contents, carbohydrates and protein of pea seeds.
