Intensity Of Soil Treatment And Frequency Of Inorganic Fertilizer Application On Nutrient Levels And Growth Of Palm Oil (Elaeis guineensis Jacq) At The Replanting Stage

Oil palm is a plantation crop that produces vegetable oil, and people highly need it, so it requires efforts to increase its production. One way by utilizing existing land without having open new oil areas with replanting. This study aimed analyze the effect of fertilization frequency on different tillage get best leaf nutrient levels growth plants. research experimented split-plot design (SPD) randomized block basic design. The factors tested in this consisted main plot, e.g., (No tillage, 1 time 2 times tillage) subplots, (D1: 5 NPK D2: 4 D3 : 3 fertilization). two were combined, 12 treatment combinations obtained. Each combination groups, totaling 36 experimental units. unit plants, 72 plants data obtained analyzed using variance further honest significant difference test (BNJ) at 5% level advanced analysis Satker application (SAS). showed increased vegetative plant (increased stem circumference). plot content (leaf N content) (plant height gain circumference increase).
