Effect of organic fertilizer on fruit yield and quality of eggplant (Solanum melongena L.)
2008
Vu Dinh Hoa, Hanoi Agricultural Univ., Hanoi (Vietnam)
Four eggplant (Solanum melongena L.) cultivars were grown in 2007 spring cropping season at Hanoi University of Agriculture to investigate their response to organic fertilizer (containing 0.37% N, 0.95% P and 1.8% K) in comparison with reduced organic fertilization and traditional practice of fertilizer application (completely inorganic) in terms of growth and fruit yield and quality traits. Organic fertilizer was obtained from microbial composting of organic agricultural and domestic wastes. It was found that organic fertilizer application for eggplant appeared to be superior to chemical fertilizers in terms of vegetative growth, fruit yield and quality attributes. Organic fertilizer slightly shortened the days from planting to flowering and improved the yield components and total marketable fruit yield in most of the cultivars investigated. Fruit dry matter content was higher and the taste better in organic treatment in all cultivars, particularly of local cultivar. Organic fertilizer can be recommended as full substitute for chemical fertilizers in eggplant production.
