Effect of Humic Acid and Yeast Waste Application on Fababean (Vicia Faba) Yield, Yield Components and some Soil Properties of Salt Affected Soil

Abstract

A field experiment was conducted during the two successive winter season 2018-2019 and 2019-2020 at Sahle El-Houssinia Agric. Res. Station, El-Sharkia Governorate to study the effect of foliar application of humic acid and yeast industrial waste (liquid and dried) on faba bean (Visia faba) yield, yield components and some soil properties of salt affected soil. The treatments were 8 gL, liquid yeast waste 6 cmL and dried yeast 10 gmL. Humic acid and yeast waste were sprayed during growth period four times every 10 days after 30 days from sowing by 600 L.ha- on soil and plants. Application of humic acid and yeast waste (liquid or dried) decreased soil pH, EC, ESP, increased infiltration rate, porosity, stable aggregate and decreased bulk density for two seasons. Also, application of humic acid and yeast waste were significantly effect on plant height, number of branch / plant, number of pods plant, weight of 100 seeds, biological yield and seed yield. Seeds N, P, K, Fe, Zn, Mn contents significantly increased compared to control due to application humic acid, liquid yeast and dried yeast.
