Determination of optimum levels of nitrogen, phosphorus and potassium of oil palm seedlings in solution culture

Balanced nutrient elements in fertilizer play a critical role in oil palm seedling successful growth and development, and at the same time reduces of fertilizer losses in the environment. This study examines the effect of different levels of N, P2O5 and K2O for oil palm seedlings in solution culture on growth traits, nutrient uptake in plant tissues and biomass accumulation under nursery conditions. Five concentration levels of N (50, 100, 300, 600 and 900 mg L–1), P2O5 and K2O (15, 30, 60, 90 and 120 mg L–1) were used in a completely randomized design (CRD) with five replications for each...
