Abstract

A field experiment was conducted to study the effects of different concentrations of vermiwash (1, 3 and 6 L fed-1) complemented by foliar application of magnesium (1000, 2000 and 4000 ppm) on growth, yield, nutritional status of potato plant (Solanum tuberosum, L. cv Kara) at the Agricultural Production and Research Station, National Research Centre (NRC), Nubaria Province, Egypt during two successive winter seasons 2023 and 2024.
The obtained results revealed that the combination between using vermiwash and Mg foliar application resulted in improved growth and yield parameters of potato plants. As for crop quality, including the protein and starch content of tubers and the total chlorophyll content of leaves, it was noted that spraying magnesium and vermiwash was important in improving these qualities in potato plants during the two successive growing seasons, especially with spraying high concentrations of magnesium and vermiwash. Spraying magnesium increased the tubers’ nitrogen and magnesium content, while there was no significant effect on both phosphorus and potassium. Spraying vermi-wash on plants had little effect on the nitrogen and phosphorus content of tubers, while it did not significantly affect the potassium and magnesium content of tubers.
In order to get a high crop with high quality requirements, it is vital to consider spraying plants with magnesium, one of the primary nutrients important for plant life. Vermiwash is another organic material that soil worms can make and that can be utilized to produce a high yield.
