The Application of Topographical Survey and the Arcgis Spatial Analys “Darcy Flow” Tool in Managing the Nurseries of Rubber Tress

Abstract

Farmers often rely on the physical appearance of rubber tree seedlings to decipher on growth rate. In situations of doubt especially when there is obvious reduction in chlorophyll or coax decay of roots, the most likely situation is induction by flooding. A sound nursery management technique which is both responsive to continuous monitoring of the terrain and also able to generate data for restoration is most desired. This study therefore employs a geospatial technique whereby topographical survey was used to pick field data while Geographical Information System analyses was able to generate accurate information on areas likely to both surface and underground discharge of materials. This method was also able to sum up all affected areas, alongside other attributes like the direction of surface flow and the rate of discharge.

A Simplified Cultivation Technology for Disbudding of (<i>Hevea brasiliensis</i>) Stock Seedling

“…Although Philippines and Ivory Coast have mentioned to the timely removal rootstock buds, but its specific operation described is lack [5] [6]. Previous reports have been related to disbudding of rubber seedlings but it is a lack of specific method description [7]- [9]. Chinese rubber seedling breeding workers generally use hand or a knife to get rid of rootstock buds, but workers need to bend over or squat to complete the disbudding work.…”
