Title: Study on the Effects of Various Irrigation Methods on Tomato Seed Production
Abstract: The experiment was conducted to investigate the effect of irrigation methods and levels on yield and quality of hybrid tomato seeds and it also amied to comparative by study the contruction and running costs when the seeds were grown on sandy loam and clay soil on the farmer fields in Khon Kaen during October 1986 to February 1987. The irrigation methods were: bucket watering, drip irrigation and furrow irrigation where as the 3 levels of water were 2 4 and 6 I/sq.m1d The results from the sandy loam plot showed that the irrigation method did not have a significant effect on total seed yield. The seed yield obtained from furrow irrigation was significantly lower than those of bucket watering and drip irrigation. Regarding the irrigation levels, it was found that irrigating at 2 I/sq.m1d. gave poorer those yield and quality than from higher irrigation levels of 4 and 6 I/sq.m1d. In addition, furrow irrigation also resulted in higher proportion of fruits but showing a symtom of blossom end rot. In clay soil, the bucket watering and drip irrigation gave a significantly higher fruit weight and seed yield than furrow irrigation. The optimum water level frund in this type of soil was about 4 I/sq,m1d. From comparing the irrigation cost, it was shown that the cost of bucket watering, furrow irrigation and drip irrigation were 1,465 1,839 and 2,151 Baht respectively (for growing 1,000 tomato plants).
