Nutrient accumulation in fruits and grains of black pepper at different ripenin...
Dalazen,Jéssica Rodrigues; Valani,Gustavo Pereira; Vieira,Henrique Duarte; Ramalho,José Cochicho; Lacerda Jr,Valdemar; Romão,WandersonABSTRACT: Nutrients accumulation in plants/fruits varies according to the crop development stage and its quantification is important to determine nutrients exportation for fertilization planning and nutrient balancing. This study determined the accumulation of nutrients in different parts of Piper nigrum ‘Bragantina’ spikes harvested at two ripening stages (still-green and red-colored spikes). Assessments in se...
Micronutrient content and accumulation in leaves and bunches of black pepper du...
Dalazen,Jéssica Rodrigues; Valani,Gustavo Pereira; Gontijo,Ivoney; Dias,Jairo Rafael Machado; Partelli,Fábio LuizABSTRACT A comprehensive knowledge about micronutrient dynamics in leaves and bunches of black pepper is needed in order to proper diagnose nutrient needs, and thus facilitate fertilization management. This study aimed to evaluate micronutrient concentration and accumulation in leaves and bunches of black pepper bunches to understand the crop nutritional demand. The experiment was carried out on in a commercial...
Macronutrient dynamics in leaves and bunches of black pepper
Dalazen,Jéssica Rodrigues; Gontijo,Ivoney; Paye,Henrique de Sá; Valani,Gustavo Pereira; Tomaz,Marcelo Antonio; Partelli,Fábio LuizAbstract: The objective of this work was to determine the macronutrient dynamics in leaves and bunches of black pepper (Piper nigrum) throughout the plant reproductive cycles. The experiment was carried out in a commercial field of 'Bragantina' black pepper. Leaves and bunches were sampled every 21 days for one year, during two crop cycles. The bunches were sampled from the twenty eighth day after the appearanc...
