Seasonal Distribution Maps, Management Practices and Profitability Analysis of Vegetables in the Selected Area, Nay Pyi Taw

抄録

Detailed information on seasonal distribution of vegetable growing areas and comprehensive study on cultural practices of some commercial vegetables are still lacking in Myanmar. This study was done to produce seasonal distribution maps of vegetables for the selected area and to analyze crop management practices and profitability of the selected commercial vegetables. Kyee Inn village tract, Pyinmana Township, Nay Pyi Taw was selected and studied from May 2016 to December 2017. Total study area was 483 ha and DJI Phantom 4 drone, Lichi software, GPS device, pix 4D software and ArcGIS were used to draw the maps. A total of 50 vegetable farmers were interviewed to analyze crop management practices and profitability for selected five commercial vegetables; okra, chilli, yard long bean, cucumber and ridge gourd by using descriptive analysis and profit function. The result showed that 15 kinds of vegetable were distributed year-round and total vegetable production areas ranged from 3.69 acres (0.31%) to 17.61 acres (1.44%) of total cultivable land. Farmers used hybrid seeds except for chilli and practiced their preferable spacing, not following the recommended one provided by Department of Agricultural Research (DAR). Farmers commonly used high dosage of urea and some farmers used wrong pesticides to control green leaf hopper, leaf miner, powdery mildew and rust. Moreover, most farmers had no awareness on using pesticide. Okra production gives the highest Benefit Cost Ratio (BCR) of 2.5 if it was grown in less than average acre. But, in chilli and ridge gourd production, BCRs (2.7 and 3.7) were the highest in ‘average growing acre’. Yard long bean and cucumber production give the highest BCRs (2.5 and 2.5) in ‘above average growing acre’. In total cost of production, labor cost was the highest followed by fuel cost for irrigation.
