ABSTRACT
This study was undertaken to determine the effect of the implementation of various cultivation factors; fertilization (X1), plant spacing (X2), weeding (X3), seed selection (X4), hilling (X5), leaf harvesting (X6) and pest control (X7) on the productivity of aloe vera leaves in Pontianak city, West Kalimantan. The research took place from June to December 2023. The results indicated that plant population, ash application, manure, pruning frequency, and harvesting frequency had very significant effects on aloe vera productivity, while urea and KCl fertilization had only significant effects. However, bed height, plant spacing per bed, seedling leaf count, seedling age, lime application, SP-36 fertilizer and pest control had no significant effects. The application rates were 932.25 kg/ha for ash, 133.00 kg/ha for urea, 209.38 kg/ha for KCl and 1.134 t/ha for manure. The greatest direct effect of cultivation practices on aloe vera productivity was from the harvesting frequency, with a contribution of 38.76%, followed by leaf pruning frequency (13.26%), ash application (13.19%), manure (5.69%), urea (2.05%) and KCl (2.02%). The indirect effects of urea, KCl and manure on productivity, mediated through ash, were found to be greater than their direct effects.
