Abstract
Aloe vera L. plants contain various kinds of chemical compounds that are very beneficial for health, so this plant needs to be developed. The limited availability of fertile lands has resulted in the aim of making sandy soil potential for Aloe vera cultivation. The experiment was arranged in a Randomized Complete Block Design with three replications. The first factor was the rate of cow manure, i.e., 30 and 45 t ha-1. The second factor was nitrogen sources of 300 kg ha-1 with 15% addition of humic fertilizer, i.e., urea, AS, NPK, KNO3, humic urea, humic AS, humic NPK, and humic KNO3. The variables measured include water content, protein, fat, carbohydrate, crude fiber, ash, and fresh weight of the leaves. The data were analyzed using analysis of variance at 5% of significance then followed by Duncan’s Multiple Range Test at 5% of significance. The results showed that there was a significant interaction between rates of cow manure and a source of humic nitrogen on all variables. The highest leaf nutrition content was obtained at a rate combination of 30 t ha-1 of cow manure with humic AS, while the carbohydrate content was obtained using a combination of 45 t ha-1 of manure with KNO3 or urea humic acid. The highest growth and yield of the plants was obtained at a combination among 30 t ha-1, manure, and humic urea.
