A questionnaire-based survey was made of 800 papaya growers in 8 provinces in northeastern Thailand in January to December 2014. The results showed that most of the growers were female, aged over 30, and educated to primary school level. They had an average of 11–15 years experience growing papaya. Most (72%) grew papaya on mixed plantations. Larger monocrop plantations were found mainly in Kalasin and Mukdahan Provinces. Both household and hired labor was used. The most popular cultivars were ‘Khaeg Nuan’ and ‘Yellow Krang.’ Most farmers saved their own seed and propagated papaya by seed, starting in plastic bag containers. A planting space of 1.7 x 1.7 m was commonly used on large plantations while on some of the mixed farms a wider planting space of 2 x 2 to 3 x 3 m was used. Most farmers used both chemical and organic fertilizer and over 75% relied on rain water for irrigation. They used both mechanical and chemical methods for weed control and pest control. The pest problems reported were red spider mites, aphids, mealy bugs, coccids, worms and snails. The most serious disease problem was Papaya Ring Spot Virus. As for production costs, in the pre-harvest period land rental accounted for the greatest proportion of costs for small-scale farmers and labor accounted for the least proportion of costs. During the harvest period, the highest costs for small-scale farmers were for the irrigation system, and the lowest were for chemical fertilizer. The large-scale farmers had the highest overall costs for chemical fertilizer. In all 8 provinces surveyed, the majority of growers (88%) sold their papaya in unripe form and none of them sold papaya to factories for processing. The prices paid to farmers for papaya were the highest in January, April and November and the lowest in July, February and August. Farm gate prices were higher in Kalasin and Nakhon Ratchasima than in the other provinces.
Highlights
• The majority of farmers surveyed grew papaya as part of an integrated farming system
• Most of the farmers are middle-aged and there appears to be a shortage of younger generations continuing in the farming business
• There is considerable seasonal variation in the prices paid to farmers for unripe papaya
• The Papaya Ring Spot Virus epidemic is a continued threat in this growing area
