RESULTS OF THE ADLAY DEMONSTRATION (Coix Lacryma-Jobi L.) IN SON LA

Abstract

The adlay demonstration implemented in Phong Lap commune, Thuan Chau district, Son La province in 2022 with a total area of 1ha and arranged in a non-repeating large plot. In which, the demonstration is planted at a density of 10 thousand trees/ha (20cm tree spacing, 50cm row spacing); using fertilizer 500 kg NPK (ratio N:P:K = 5:10:3), 300kg urea nitrogen, 150 kg potassium chloride; control plots planted at a density of 13.3 thousand trees/ha (15 cm tree spacing, 50 cm row spacing); The amount of fertilizer is estimated at 600kg/ha of NPK (ratio N:P:K = 5:10:3), 200kg/ha of urea nitrogen. The results of the demonstration show that: Adlay grows and develops well, the yield is 2.71 tons/ha (increasing 46.5% compared to the control), the economic efficiency is 32,400,000 VND (increased 59.2% compared to the control). This result is completely consistent with the results of research on agro-biological characteristics, experiment on planting density, experiment on fertilizer formula conducted by the author and the research team. Therefore, the results can be applied in practice.
