Effect of Plant Density on Growth and Yield of Tomato (Solanum lycopersicum L.) at Thai Nguyen, Vietnam

This study was conducted to evaluate the planting density on growth and yield of tomato fruit to determine the optimum planting density. Plant height, number of leaves per plant, fruit set, number of fruit per plant, fruit weight and fruit yield were recorded. Results indicated that treatment with 35714 plants per hectare had the highest plant height, whereas 25974 plants per hectare gave the lowest plant height. Moreover, 25974 plants per hectare had the best results in fruit set, fruit number as well as fruit weight. Planting density with 25974 plants per hectare gave the maximum fruit yield than the other treatments. It was concluded that 25974 plants per hectare significant improve fruit growth and yield of tomato fruit under field condition.
