Effect of rotation and fertilization on tomato in the Mediterranean organic farming system: case of Turkey
Abstract
Technical and economic feasibility of rotation programs have significant impact on the success of organic production. This study was designed to test the effect of different soil building crops including legumes to be used as green manure (Vicia sativa), for grain production (Vicia faba) and a commercial crop broccoli (Brassica oleracea var. Italica) on tomato yield and quality under organic management. A fallow control was used. During the tomato growth, fertility was maintained by a commercial compost supplied in two forms: compost alone and compost complemented with compost tea. Treatments were arranged in a split plot design with four replicates and two factors having as main factor the soil building crops and as second factor the fertilization. Compost alone increased tomato yield significantly. The highest yield was obtained in the interaction faba bean and compost.
[...]
Both factors did not have any marked effect on tomato fruit quality and on soil total N and available P and K contents in the first year. Common vetch and compost application gave the highest gross margin due to a combination of high yield and low production costs.
