Abstract

The purpose of this current study is to evaluate the effects of growing season, nitrogen fertilizer level and planting density on the cultivation of Te meo Son La rice variety. Here, formulas of each growing seasons, planting densities and nitrogen fertilizer levels were used to assembly the growth and development of the Te meo Son La rice variety in 2018 and 2019. As the results, the growing season from 4^th to 11^th, July was the optimum period for Te meo Son La rice production as stable productivity and slightly susceptible to major pests and diseases. Next, the planting density of 30 - 35 hills/m² was highly recommended for Te meo Son La rice production. Our analysis also demonstrated that the formula of 1 ton of cattle manure + 70 kg N + 60 kg P₂O₅ + 50 kg K₂O per 1 ha field exhibited the optimum results for the cultivation of Te meo Son La rice variety. Taken together, our results could provide major evidence for construction of the cultivation practices of Te meo Son La rice variety.
