Abstract
The study on the effect of nitrogen and potassium fertilizer levels on the growth, yield of aloe vera (Aloe vera L.) in the sandy soil ofBinh Thuan, from June to November 2023. The two-factor experiment was arranged in a Split - plot design with three replications. The main factor (main plot) was three potassium levels including 85; 95 and 105kg K2O ha-1 year-1 and the secondary factor (main plot) was three potassium levels including 85; 95 and 105kg K2O ha-1 year-1. The secondary factor (sub plot) was five nitrogen fertilizer levels including 130; 150; 170; 190 and 210kg N ha-1 year-1 .The basis application was 30 tons of farmyard manure + 160kg P2O5 ha-1 year-1 . The research results showed that different amounts of nitrogen and potassium had a clear impact on plant height, leaf length, number of leaves/plant, yield and yield components. Aloe vera plants were fertilized with 190kg N combined with 105kg K2O ha-1 year-1 on 30 tons of farmyard manure and 160kg P2O5 ha-1 year-1 for the highest leaf length (52.3cm) and leaf yield (35.5 tons/ha).
