Effect of banana pseudostem sap as liquid fertilizer in onion

An investigation was carried out at Soil and Water Management Research Unit Farm, NAU., Navsari during rabi season of 2008–09 to study the feasibility of using banana pseudostem sap as liquid fertilizer in onion under drip irrigation. Banana speudostem sap is rich in nutrients and having growth promoting substances, its judicious utilization in crop production enhances crop yield with very less input costs. Due to various treatments yield of onion bulbs produced from 80% RDF along with sap @ 2000 l/ha under drip irrigation. In case of nutrient content and uptake, 100% RDF with sap @ 2000 l/ha gave highest values which were followed by 80% RDF + sap @ 1500 Vha. These treatments produced higher nutrient availability in soil.
