Abstract:
One of the factors that takes an important role in crop productivity is fertilization, especially in an immature plant (TBM). The goal of this research is to study the morphological response of immature oil palm plants as result of the single fertilizer N, P and K. Treatment design uses Randomized Completely Block Design (RCBD). The applied treatment consists of 4 treatments, control treatment (basic fertilizer) and three treatments of single fertilizer combination. Each treatment is repeated three times so that the total unit tests are 12 plants. The observation of plant morphology includes: plant height, stem circumference, the number of leaf midrib, the ninth midrib leaf length, and the ninth stem leaf width . The results show that the single fertilizer treatment does not have a significant effect on plant height, stem circumference, the number of leaf midrib, the ninth midrib leaf length, the ninth stem leaf width on the palm in 1-3 Months After Treatment (MAT). Nevertheless, the
effect of the treatment shows that the higher single dosage package of fertilizer (PT1, PT2 and PT3) is applied, the more increasing the plant height is. The highest growth increase occurs on the stem circumference and the ninth leaf width, that is 31.51% and 26.32%; wider than the control.
