PRODUCTIVITY AND ECONOMICS EFFECTIVITY OF THE COFFEE PLANTING MODEL IN SON LA BY APPLYING DRIPPING TECHNOLOGY

Abstract

Assessment on the productivity and economics effectivity of the experimental model by applying Israel dripping system in Chieng Ban commune motivate to expand the dripped coffee area in Son La. The researcher observing the coffee plants in each 1 hectare model after 4-year pruning, 2,600 trees per hectares density by the critera releavant to soil moisture, growth, productivity creating element, produtivity and economics effectivity. The result of experiment shows that the criteria including soil moisture (55.32%), chlorophyll index (478.22), leaves areas (50.47 mm²), the number of berry bearing branches (13.76 pairs/tree), the number of berry/knot (6.53 berries), the weight of 100 fresh fruit (158.33 g), individual yield (1.625 kg/plant), yield (3.928 ton/ha), economics effectivity (21.956 million VND) increase better comparing to control model in 2016. This proves that applying dripping technology into coffee plant is the more effective economics than non-applying.
