Abstract

Producing off-season organic tomatoes to take advantage of the highland climate is a sustainable direction for the northern mountainous region of Vietnam. However, finding the suitable tomato variety and different off-seasons was still unanswered. The two-factor experiment was arranged in Split-plot design with mainplot as: three off-season planting date (March 25, 2023 (season 1-V1), April 14, 2023 (season 2-V2), May 7, 2023 (Season 3-V3)), while subplots were three tomato varieties as: G1 - HT179 variety, G2 - Savior variety and G3 - TV20 variety with three replications. The experimental results confirmed that the climatic conditions in Van Son highland commune are completely capable of producing off-season organic tomatoes. V1 off-season was the most suitable for growth, physiology, yield and quality of tomatoes with actual yields 16.1% and 60.38% higher than V2 and V3 respectively. The G2 tomato variety was the most suitable for off-season organic tomato production with an actual yield 38.72% and 51.48% higher than the G1 and G3 varieties, respectively. Combining V1 and G2 variety was the most suitable treatment for Van Son highland commune and communes with similar conditions for the significantly highest in actual yield, and achieved the good quality characteristics as compared with other treatments.
