Daftar Isi:
- The objective of this research was to study the effect of N, P, K and Mg fertilizers on growth and quality of Aloe vera chinensis in peat soil of Indragiri Hilir Riau. The research was conducted at PT Bhumireksa Nusasejati Plantation, Indragiri Hilir Riau. The research was arranged by Factorial Randomized Block Design with 4 factors, 4 levels, 3 replications. The first factor was N dosage fertilizer (N0=0g, N1=5g, N2=10g, N3=20g N/plant/month), The second factor was P dosage fertilizer (P0=0g, P1=4g, P2=8g, P3=16g P2O5/plant/month), The third factor was K dosage fertilizer (K0=0g, K1=7.5g, K2=15g, K3=30g K2O/plant/month), The fourth factor was Mg dosage fertilizer (Mg0=0g, Mg1=2.5g, Mg2=5g, Mg3=10g MgO/plant/month). The results showed that the application of N, K and Mg dosage significantly increased plant height, leaf length, leaf width, leaf thickness, and the number of leaf by quadratic response. Combination of N and P fertilizer significantly raised the leaf fresh weight. The complete treatment (NPKMg) and single factor either N and Mg did not increase the total chlorophyll and protein content , in contrast, P and K as a single factor significantly increased the total chlorophyll but not protein content. Gel of Aloe vera consisted of 17 essential amino acids
