Abstract

Rubber smallholders often face challenges due to their insufficient training and lack of proper input on tapping techniques, which result in low rubber yield productivity. Non-compliance with tapping frequency guidelines by smallholders further exacerbates yield issues. Additionally, the selection of rubber clones planted affects latex productivity, with issues such as panel dryness being significant contributors. This study focuses on investigating the effectiveness of HydroStimulant 1 on rubber trees with tapping panel dryness. HydroStimulant 1 is a stimulant designed to enhance rubber yield, reduce partial dryness, and promote bark regeneration. The research was conducted in Kampung Padang Chenderai, Kedah, using ten selected 9-year-old PB 350 clone trees. Monthly applications were carried out from February to May, with observations made on several parameters including cup lump weight, panel dryness length, and latex pH value. The trees showed an average increase in cup lump weight of 2 kg/tree. Application of HydroStimulant 1 over four months resulted in complete recovery from panel dryness in 40% of treated rubber trees, with an additional 40% showing reduced dryness length, while 20% remained unresponsive to the treatment. Although the application of the stimulant slightly altered the pH of fresh latex, the change was not significant. Based on ANOVA results, the application of the stimulant significantly increased cup lump weight (p < 0.05), resulting in higher latex yield. However, the treatment did not demonstrate statistically significant effects in reducing panel dryness (p > 0.05), suggesting the influence of other factors. Nonetheless, the stimulant demonstrated potential in controlling the latex pH within the desired range, thereby improving latex quality.
