Background: Sowing density optimal is rated a less expensive solution for enhancing the output of tomato yield in the background of extending food requirements worldwide. Methods: The main objective of this study is to investigate the sowing density effect on the growth and tomato yield planted in Don Duong district of Lam Dong province, Vietnam. The study was conducted during the spring tomato crop (January to June 2020) with five different sowing densities varying from 33000 to 50000 plants/ha based on drip irrigation system supply approximately 100% of actual evapotranspiration. Result: Results pointed out that among investigated sowing densities, sowing density 45830 plants/ha obtained the optimal fruit yield (OFY) up to 87.8 tons/ha compared with different sowing densities while other observed variations as the number of bunches, fruit weight per plant and diameter were no significant difference. Based on the findings, tomato growers can sow with a density 45830 plants/ha to obtain the OFY thereby contributing to increase profits.
