STUDY ON THE INFLUENCE OF DENSITY ON THE GROWTH, DEVELOPMENT, PRODUCTIVITY AND QUALITY OF AMOMUM LONGILIGULARE T.L.WU. PLANTED IN THE SHADE OF RUBBER TREES IN HARVESTING TIME IN THANH HOA PROVINCE

Abstract

This article is the result of a study on the influence of density on the growth, development, productivity and quality of Amomum longiligulare T.L.Wu. The experiment was arranged by Random Complete Block (RCB) with 4 treatments and 3 replications. At the planting distance/ space 1 x 1m, the density of 10.00 trees/ha, the productivity is at high level of 291.3kg/ha, the quality is good 1.62%; percentage of good/solid seeds 83.44 ± 5.91%; P 1000 seeds: 165,35±4,66g; Basing on these figures, standard for good seeds is formed.
