PLANTING OF RAMIN (GONYSTYLUS BANCANUS KURZ) WILDING IN PEAT SWAMP THICKET OF CENTRAL KALIMANTAN

Abstract

The purpose of this study was to determine the effect of planting row with different widths on the growth of Ramin seedlings planted in the area of peat swamp thicket. The research design used was Randomized Block Design (RBD) with 3 treatments, namely L0 = planting in a row without a clearance; L1 = planting in a row with a clearance of 1 m width; L3 = planting in a row with a clearance of 3 m width each of 3 plots (plot size 30 x 30 m) with a plant spacing of 5 x 5 m, so that the total number of seeds equal to 324 seeds. The variables measured and observed were the success / percentage of life of Ramin plants, percentage of bud growth and relative growth rate. Observations and measurements are carried out every 2 (two) weeks. The success of the plant life was 72,5%. The success of bud growth 34,9% and a relatively high growth rate of 11,1%. The bud growth and the relatively high growth rate of the Ramin plant in the peat swamp thicket for six months resulted in the highest growth in the treatment of Ramin planting in the row without clearance compared with planting in the row with the clearance of 1 and 3 meters width.
