Nutrient uptake of black pepper (Piper nigrum) at the onset of production

Nutrient uptake by black pepper (Piper nigrum) is crucial for estimating its nutritional demand and designing efficient fertilization plans. This study evaluated nutrient absorption in different plant organs during the initial production stage (1,5 years) in a crop located in Valle Hermoso parish, Santo Domingo de los Tsáchilas, Ecuador. A completely randomized design was used, applying the Di Rienzo, Guzman and Casanoves test for mean comparisons (a = 0,05). Treatments included plant organs, macronutrients, and micronutrients, with three replicates per treatment. The main results revealed that leaves had the highest contents of nitrogen, potassium, and calcium calcium (2,86 ± 0,18 to 3,14 ± 0,26 dag kg-1), while roots accumulated higher amounts of boron, zinc, copper, and iron. Similarly, leaves absorbed the largest quantities of nitrogen, calcium, and sulfur (1,00 ± 0,32 to 40,5 ± 3,1 kg ha-1), as well as boron, zinc, and manganese (32,6 ± 3,9 to 217,1 ± 21,5 g ha-1). Macronutrient uptake followed the order nitrogen = potassium = calcium > magnesium > phosphorus = sulfur, while for micronutrients, it was iron > manganese > zinc > boron > copper. These findings are essential for designing fertilization plans that optimize nutrient availability and uptake in black pepper crops during their initial production stage.
