Evaluasi Kebutuhan Spesifik Unsur Hara Makro Primer Untuk Produksi Mini Cutting Tiga Klon Tanaman Induk Eucalyptus Hibrida

---

Management of specific primary macronutrients (N, P, and K) is essential
to ensure the growth and development of Eucalyptus hybrid mother plants. This
research was conducted at the R&D Nursery greenhouse and Soil Laboratory,
Tualang District, Siak Regency. The objective of this study was to analyze the
effect of specific primary macronutrients for the mini cutting production of three
Eucalyptus hybrid mother plants, determine the optimal dose of primary
macronutrient requirements on three Eucalyptus hybrid mother plants, and
analyze the interaction of N, P, and K nutrient content with other nutrients on
three Eucalyptus hybrid mother plants. This experiment was designed as a splitplot
completely randomized design (CRD) with three Eucalyptus hybrid mother
plants as the main plot and different doses of N, P, and K as a subplot with 4
replicates and a total of 156 trial plots. The observed variables included shoot
productivity, shoot length, shoot fresh weight, shoot biomass, root length, number
of roots, rooting rate, and shoot nutrient content. The collected data were
analyzed statistically using descriptive analysis, Principal Component Analysis
(PCA), Analysis of Variance (ANOVA), quadratic regression model, and
interaction interaction analysis between observed variables and interactions
analysis between nutrients using Pearson Test Correlation. The results showed
that the application of specific primary macronutrients gave a different pattern of
response variability in clone E3 (E.pellita x E.urophylla), whereas in clones E1
(E.pellita bulked provenance) and E2 (E.pellita x E.pellita ) tend to have the same
pattern. Optimum doses on E1 N 440 mg/l, P2O5 271 mg/l, K2O 200 mg/l,
clone E2 N 384 mg/l, P2O5 111 mg/l, K2O 160 mg/l, and clone E3 N 394 mg/l,
P2O5 223 mg/l, K2O 200 mg/l. In general, the interactions between nutrients
varied in each Eucalyptus clone. Positive interactions between N and S and B,
and negative interactions between N and P, Ca, Mg, Mn, and Mo. Positive
interactions between P and N, Mg, Mn, and Mo, and negative interactions
between P and Fe, Zn, and Cu. Negative interactions between K and P, Ca, Mg,
Fe, B, and Zn.
Key Words: Eucalyptus, mother plants, primary macronutrient management
