The Influence of Aquaculture to Leaf Productivity Aloe Vera L. In Pontianak City

Setiawan Setiawan

Abstract


The objectives of the research were to find out (a) the effect of Aloe Vera L. culture, consisting of fertilizing (X1), plant spacing (X2), weeding (X3), seed selection (X4), Planting (X5), leaf collection (X6), and crop pest control (X7), on the productivity of Aloe Vera L. in Pontianak City West Kalimantan, and (b) the direct or multilevel effects of Aloe Vera L. culture on the productivity of the Aloe Vera L. leaves cultivated by farmers in Pontianak City West Kalimantan. The research was conducted at the farmers’ Aloe Vera L. gardens in Pontianak Utara Subdistrict, Pontianak City, West Kalimantan Province. The proposal preparation, data collecting and processing were started from June to December 2012. The result indicated that the plant population, the provision of Aloe Vera L. ash and manure, the frequency of pruning and harvesting (P < 0.01), and the provision of Urea and KCl fertilizers (P < 0.05) had significant effects on the productivity of Aloe Vera L. plants, except for the height of plots, the plant lines per plot, the number of seed’s leaves, the age of seed, the provision of lime, SP-36 fertilizer, and the control of crop pests. The provision of Aloe Vera L ash, Urea, KCl, and manure was 932.25 Kg ha-1, 133.00 Kg ha-1, 209.38 Kg ha-1, and 1.134 Kg ha-1, respectively. The biggest direct effect of the culture on the productivity of Aloe Vera L. was the frequency of harvesting that contributed 38.76 %, followed by the frequency of leaf pruning (13.26 %), the provision of Aloe Vera L. ash (13.19 %), the provision of manure (5.69 %), and the provision of KCl (2.02 %). The indirect effect of Urea, KCl, and manure on the productivity would have greater effects compared to their direct effects.
