Creating forecast equations to study factors affecting the quantity of para rubber production

Abstract

The purpose of this research was to study the factors affecting the quantity of para rubber in Ban Pueng Tuek community, Tatum sub-district, Sangkha district, Surin province. A total of 5 factors were studied, namely 1) rubber planting area 2) rubber tapping 3) use of pre-tapping and post-tapping nourishing fertilizers 4) rubber varieties planted 5) diseases and pests of rubber. research tools was a satisfaction questionnaire on various factors affecting the quantity of rubber production. The sample group includes 56 rubber planters or rubber planters who own the plantation in Tatum Subdistrict, Sangkha District, Surin Province.

          The results showed that all 5 factors were related to the quantity of para rubber production at a relatively high level. The multiple correlation coefficient was 0.288 and the production volume was predicted 53.7% with statistical significance at the 0.05 level, indicating that the said factor could explain the change in the rubber production volume of 53.7%. The regression of the forecasters found that only 2 factors could predict the yield. and rubber tapping Factors related to rubber planting area Fertilizer application before and after cutting Diseases and enemies of rubber There was no statistical significance at the 0.05 level. The equation for forecasting the quantity of rubber production could be written as follows. The forecast equation in the form of raw score Y = 6.867 + 0.602X₂ + 0.139X₄ The forecast equation in the form of a standard score Z = 0.302Z₂ + 0.181Z₄.
