Research on the effect of planting distance and potassium fertilizer amount on the yield and germination rate of hedyotis diffusa willd. Thanh Hoa province

Abstract

Study on the effects of planting distance and potassium fertilizer on the yield and quality of Hedyotis diffusa Willd seeds in Thanh Hoa with the aim of evaluating the growth, development, seed yield and germination rate of Hedyotis diffusa Willd seeds. The results of the interaction study between the planting distance of 20 x 20 cm and the amount of potassium fertilizer of 100 kg K2O/ha gave the best growth and development indicators, the actual yield ranged from 21,26 - 21,37 kg/ha and the seed germination rate reached >85%, higher than other formulas at the significant probability level with LSD0,05. The results of this study aim to improve the production process of Hedyotis diffusa Willd seeds.
