Fertilizer Formulations and Methods of their Application Influences Vegetative Growth and Productivity in Organic Greenhouse Tomato

Abstract

Investigations were conducted from 2006-2010 in order to develop a package of cultivation practices for producing organic greenhouse vegetables under Kuwait's environmental conditions. One of the objectives of these investigations was to evaluate different organic fertilizer formulations with a view to select fertilizers for organic greenhouse vegetable production. Commercial organic fertilizer formulations viz. Earth juice, fish hydrosylate (Neptunes Harvest), seaweed and desert bat guano (Squantos secret) were evaluated in different proportions, either as soil drench or foliar applications in tomato. Results revealed that soil application of Earth juice products and fish hydrosylate produced equally good or even better vegetative growth and fruit yields as compared to conventional fertilizers. Soil application of organic fertilizers was found to be significantly effective than the foliar application.
