PENGARUH PUPUK N, P, K DAN Mg TERHADAP PERTUMBUHAN DAN KUALITAS LIDAH BUAYA (Aloe vera chinensis) PADA LAHAN GAMBUT INDRAGIRI HILIR RIAU
Abstrak: 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,
