Abstract

A field experiment was conducted to study the effects of different two irrigation systems (Sprinkler and Dripping) complemented by foliar application of vitamin E (0, 50, 100, 200 and 250 mg l-1) on growth, yield and nutritional status of sweet corn plant (Zea mays L. cv Dorado) under saline water irrigation, at the Agricultural Production and Research Station, National Research Centre (NRC), Nubaria Province, Egypt during two successive summer seasons 2023 and 2024.
The results indicate that drip irrigation has higher growth and yield coordinates as well as nutritional status compared to sprinkler irrigation system during the two successive growing seasons. Under saline irrigation conditions, spraying vitamin E at a rate of 200 mg l-1 with drip irrigation significantly improved growth parameters, yield and nutritional status of sweet corn plants during two successive growing seasons.
We can say that spraying vitamin E on sugar corn plants grown in sandy soil and irrigated with salty water can be one of the safe ways to reduce the effect of salinity on the growth and productivity of plants. Also, the drip irrigation method is the most suitable irrigation method when using salty water for irrigation.
