Research and Development of Technology for Producing of Edible Indigenous Vegetables with Commercial Potential in Suratthani Province

Abstract

This research was aimed to study effect of the planting density and pruning on top edible indigenous vegetables yield such as Glochidion Perakense and Cashew nut (Anacardium Occidentale) was carried out to identify suitable planting density for top edible yield after 10 months planting. The research was carried out during 2022 and 2023 in Suratthani Agricultural Research and Development Center, Suratthani Province. This research used the Randomized Completely Block Design with 4 replications. The two levels of plant density as 1,600 plants/rai (1x1 m.) and 711 plants/rai (1.5x1.5 m.) and the three patterns of plant pruning as not pruning (control), open leader and modified leader. A trial unit (plot) was 48 experimental units and 50 trees plant/unit test. The results when trees 10 months after planting which pruning all of 6 treatments. The result found that the plating density by used 711 plants/rai (1.5x1.5 m.) gave to highest top edible of Cashew nut yield 41.55 g/tree/time and gave to highest top edible of Glochidion Perakense yield 98.06 g/tree/time. In this trial, when consider total cost and income from the yield of top edible vegetable, found that density by used 1,600 plants/rai (1x1 m.) and pruning by open leader pattern were recommended for maximum income and top edible of Cashew nut while density by used 1,600 plants/rai (1x1 m) and pruning by modified leader pattern and were recommended for maximum income and top edible of Glochidion Perakense.
