Abstract

Extensive use of chemical fertilizers to increase yields of crops grown in rain-sheltered houses may impair the physicochemical and biological properties of the soil. Organic liquid fertilizer based on vinasse produced by sugarcane fermentation is increasingly being used as an alternative to chemical fertilizers. The objectives of this study were to analyze the growth characteristics, yields, and nutrient utilization efficiency and measure the effect of soil microbial enzymatic activity when using organic liquid fertilizer based on condensed molasses soluble with red pepper (Capsicum annuum L.) under protected cultivation. Four different fertilizer treatments were applied: no fertilizer (CON), chemical fertilizer (CF), chemical liquid fertilizer (CL), and organic liquid fertilizer (OL). Soil and plant nutrient contents, plant nutrient use efficiency, and soil enzyme activity were analyzed in each treatment. The fresh and dry weights of red peppers treated with organic liquid fertilizer increased, and fruit dry weight was similar between CF and OL. The P and K use efficiency of red peppers treated with organic liquid fertilizer increased, and the organic matter and available P2O5, K, and Ca contents of soil in organic liquid fertilizer treatment increased compared to chemical fertilizer treatment. In addition, the urease and β-glucosidase activity in organic liquid fertilizer treatment increased significantly, which may stimulate nitrogen and carbon circulation in soil. In this study, it is shown that the use of organic liquid fertilizer based on vinasse of soluble condensed molasses improves red pepper production similar to chemical fertilizers in addition to improving the soil chemical properties and microbial activity.
