Determination of the uptake and translocation of nitrogen applied at different growth stages of a melon crop (Cucumis melo L.) using 15N isotope

Abstract: Plant sampling and analytical methodsDuring the growing season, one plant of each elemental plot (four plants of each treatment) was randomly sampled at 34, 41, 48, 55, 62, 69, 76,83, 90, 97 and 104 DAT in the first experiment, at 62, 69, 76, 83, 90, 97 and 104 DAT in the second and at 50, 57, 64, 71, 78 and 85 DAT in the third. Leaves (blades and petioles), stems

“…During fruit maturity and fruit set, N absorption rate in the whole plant was linear, and similar for each melon type, suggesting that the entire melon crop could be fertilized with constant daily N amounts until 2 to 3 weeks before the last harvest regardless of melon type (Cabello et al, 2011). Lack of homogeneity in fruit maturity within the plot because of different maturity rates of each melon type resulted in excessive water supply or inadequate fertigation to some fruit types (particularly excess N without the right balance of K), causing premature cracking.…”

“…Excessive nitrogen (N) fertilization, especially with inadequate potassium (K) and/or calcium (Ca) particularly in the later stages of fruit ripening has also been reported to promote cracking and splitting (Baixauli, 1995;Baixauli et al, 1997;Cabello et al, 2011;Serrano, 1996).…”

“…Fruit cracking is caused by excessive nitrogen fertilization combined with insufficient potassium or calcium in the field [60]. Premature cracking in melon cultivars is caused by an insufficient supply of nitrogen and potassium in the open field (Figure 4) [39].…”

“…Os padrões de acumulação de nutrientes durante o período de crescimento da planta inteira seguiram o curso do tempo da produção de MS, como foi mostrado também por Cabello et al (2011). Portanto, a média entre os tratamentos foi utilizado para representar a extração de macronutrientes pelo melão em função da época de coleta (Figura 3).…”

“…Os nutrientes, N, K e o Ca são os mais exigidos pela cultura do melão, sendo que a necessidade de cada um varia com as condições de cada local, apresentando assim uma variação na sequência quantitativa destes nutrientes extraídos pelos híbridos do melão de uma pesquisa para outra com os diversos híbridos . O crescimento da planta e produção de frutos de melão dependem do suprimento de N (CABELLO et al, 2011). O K tem influência nas qualidades física e química dos frutos de meloeiro, pois é indispensável para a formação e amadurecimento dos frutos e para o aumento da textura dos mesmos (AZEVEDO et al, 2015).…”
