Optimization of Humic acid application rate by evaluating the response of mung been (Vigna radiata) yield, growth components and soil properties in western region of Saudi Arabia

Abstract

Discriminate use of fertilizers gradually damaging biological and physical properties of soil as well as bioavailability of nutrients and organic matter resulting results in low crop yield. So there is needed to equilibrate the application of inorganic fertilizer with organic fertilizers especially in arid region of Saudi Arabia to sustain and conserve soil resources for long term and better yield results. A field experiment was carried out at
