Use of Oil Palm Male Inflorescence and Sawdust as Substrate in Soilless Bell Pepper (Capsicum annuum L.) Cultivation

Faced with increasing demographic pressure and rampant urbanization, soilless farming appears as a sustainable solution for intensifying agricultural production in spaces restricted. This study aims to evaluate the effect of plant residues as an alternative substrate in soilless cultivation of pepper (Capsicum annuum L.). The evaluation of physical parameters Chemical analysis of the substrates was performed using dosages. Monitoring of agronomic parameters was done through observations and measurements. The results obtained show that the inflorescence The male oil palm and the ash tested possess physicochemical properties. Favorable to soilless cultivation. The inflorescence of the oil palm, amended by the solutions of Ash and NPK (nitrogen, phosphorus and potassium) yielded significant results on fruit growth and number. pepper. Thus, these locally available plant residues constitute an alternative promising and economical compared to imported substrates, contributing to waste recovery organics in urban and peri-urban agriculture.
