Effect of Zinc Nanoparticles on Plant Growth and Some Soil Properties

A field experiment with three replications was conducted on sprinkler irrigated sandy soil during two successive summer and winter seasons (summer 2021 2021/2022), which cultivated corn (Zea mays) faba bean (Vicia L.) at Agricultural Research Station farm in Ismailia Governorate, Egypt. Faba as an indicator crop to evaluate the residual effect of different rates zinc nutrient nanoparticles form versus mineral sulphate fertilizer studying their effects growth yield some chemical properties. The forms were applied by fertigation through irrigation system. obtained results revealed that parts dry matter, properties including available nutrients content, EC, pH SOM greatly improved general additions these forms. During treatments, most effective treatment rate half dose from minerals recommended (ZnNPs 50% MNRD). Mineral normal (MNRD) gave nearly equal ZnNPs 50 % MNRD.
