Influence of Plug Seedlings Grown at Different Elevations Planting Density and Date on Growth and Yield of Tomato cv. Known-You 301 in Fall Crop Season
The stem diameter of the seedling grown at high elevation is larger but shorter than that grown at low elevation. No significantly difference was observed in the number of node of flower initiation among the seedlings from high or low elevation and planted in September, while the seedlings planted in Octorber, high elevation plants were found with 6.3 nodes lowest for flower initiation. Total fruit number, average fruit weight, and total yield for the planted in October were higher than those planted in September. Plants from high elevation seedling were higher yield and more fruits in the first 2 weeks and accumulated to 5.1 kg in the 4th weeks, while the yield plants from low elevation seedling was from 0.2 kg to 2.9 kg. Plant density study showed, one plant per hill and with 25 cm between plants had the highest fruit number. There is no significantly difference in fruit size and average fruit weight . The plot with one plant/25 cm/hill between plants produced 2.8 kg more in yield than one plant/50 cm/hill between plants in September or October planting.
