Abstract

The study analyzed and evaluated factors influencing mushroom production in its value chain, and used them as a framework for planning production areas of mushroom in the Mekong Delta. Primary data were randomly collected from 115 farmers in Can Tho and Dong Thap provinces, and 543 rice farmers (straw supplier) in four provinces Can Tho, Dong Thap, Kien Giang, and An Giang. Added to that were secondary data collected from Statistical Yearbook of Mekong Delta provinces and descriptive statistical analysis method such as frequency, ratios, means, standard deviation, statistical classification, ANOVA analysis. The results showed that, in terms of straw management, only a few farmers collected straw in the Summer-Autumn, Winter-Spring, and Winter-Spring crops at 9%, 10%, and 12% respectively, while most of them burned or buried it in the field. Mushroom planting was mainly outdoors rather than indoors. Based on the following factors: (i) supply of straw, (ii) production conditions and techniques, and (iii) available source of irrigation water, three options were proposed for production areas of mushroom. The selected option (Option 2) opted for three production areas: Zone I with the provinces of An Giang, Dong Thap, Long An, Hau Giang, Can Tho, and Vinh Long, which were not or little affected by salinity and had sufficient fresh water all the year round; Zone II of coastal provinces Soc Trang, Kien Giang, Tien Giang, and Tra Vinh, mostly affected by salinity; and Zone III of Ca Mau, Bac Lieu, and Ben Tre, where the rice-shrimp model was predominant (Ca Mau, Bac Lieu) and witnessed an increasing shift away from rice (Ben Tre).
