- Abstract
The use of fertigation is becoming increasingly and common, which requires a thorough knowledge about the culture being used. Knowing the uptake is an important point, since this will determine how the split will occur. Among the nutrients of greatest importance to the development of crops are nitrogen (N) and potassium (K). The aim of this paper was to determine the uptake and accumulation of nutrients from cantaloupe melon type "Harper" within the conditions of Mossoró - RN, order for the recommended fertilizer application through drip irrigation. The experiment was in randomized blocks with two replications. The treatments were formed by the combination of increasing levels of nitrogen - N (N1 - 5, N2 - 37.78; N3 - 111.65; N4 - 237.65; N5 - 442.05; N6 - 666.41 kg ha-1) and potassium - K2O (K1 - 5; K2 - 82.86; K3 - 195.67; K4 - 364.61; K5 - 574.13; K6 - 827.54 kg ha-1). We assessed the biomass and accumulation of N, P and K in the plant. The dry matter accumulation in the plant was not affected by levels N and K applied by fertigation. The highest rate of absorption of nutrients occurred around 44 days after transplanting, indicating that this is the time when the plant has increased demand for fertilizer application. Nutrient requirements primary for melon followed the order: K> N> P. To N, the highest accumulation was observed in the vegetative parts (leaf + stem) and the P and K, the highest accumulation was observed in the fruit.
