“…The accumulated K in crop residues per hectare was 1.55 Mg. This confirms that K is the most required macronutrient by pineapple plants (Pegoraro et al, 2014b;Souza et al, 2019) and denotes the need for a correct management of this residue to avoid high nutrient losses in the area, which affects soil fertility, resulting in economic and environmental losses.…”

“…Macronutrient accumulation in the crop residues of the cultivars IAC-Fantástico, Pérola, and Smooth Cayenne was, in decreasing order: N > K > Ca > Mg > S > P. The largest part of absorbed and accumulated nutrients is found in the leaves, and the lowest in the roots. The quantity of exported nutrients by pineapple plants is relatively high (Souza et al, 2019), which are those immobilized by fruits and propagative organs, and is even higher in cultivars that present higher harvest index.…”

“…The nutritional demand for pineapple plants to obtain a high yield is high; K, N, and Ca are the most required nutrients (Pegoraro et al, 2014b;Souza et al, 2019). This demand varies depending on the cultivar and can be partially met by fertigation with TWW.…”

The use of treated wastewater in agriculture is a viable alternative to produce foods, which can reduce production costs in pineapple crops by substituting partially irrigation and meeting the plants' nutritional demand. This management can increase yield and plant residue and soil nutrient contents for subsequent crops. The objective of this study was to evaluate carbon and nutrient contents in residues of pineapple crops fertigated with treated wastewater. The experiment was conducted using a randomized block design with four replications, in a split-plot arrangement. The plots consisted of five treated wastewater rates: 0, 100, 200, 300, and 400% of the maximum annual limit of Na applied to the soil, which corresponded to irrigation water depths of 0, 117.3, 234.1, 351.4, and 468.3 mm, respectively. The subplots consisted in three pineapple cultivars: Pérola, Smooth Cayenne, and IAC-Fantástico. The treatments with treated wastewater doses had no effect on dry weight accumulation, and content and accumulation of organic carbon, macronutrient, and sodium in pineapple crop residues. Pineapple plants of the cultivar Pérola have lower dry biomass and carbon accumulation than those of the cultivars IAC-Fantástico and Smooth Cayenne.

“…For these practices, the K/N ratio is below or above the recommended dose and leads to a reduction in crop yield and fruit quality (Sossa et al, 2017;Djido et al, 2021). The low planting density contributes to low yields (de Souza et al, 2019;Sanya et al, 2020). Djido et al (2021) showed that, high planting density does not influence the weight of the fruits.…”

The high diversity in pineapple fields and farmers provide huge challenges in farm management in already dwindling pineapple production sector in the center region of Cameroon. A first step to overcome these production challenges is to manage the afore-mentioned diversity to a reasonable level without loss of detail and specific management interventions for each category or typology proposed. Field surveys were conducted in two pineapple producing areas in the center region of Cameroon (Awae and Bokito), with a view to collect data on pineapple farms and producers. Data collected was later subjected to multivariate analysis. 67% of farms variability was captured within 02 components: Investment, plant density, soil fertility, and input factors. Cluster analysis captured 03 pineapple farming systems typologies: (1) subsistence poor resource smallholder farmers; (2) market oriented, low to medium resource farmers; and (3) market oriented, high resource large-scale farmers, representing 62.1, 32.1 and 5.8%, respectively of farms. The unexplained 33% of variability between farms was attributed to biophysical characteristics of pineapple producing area. Pineapple production in the center region of Cameroon demonstrates enormous potential for improvement. Understanding these bio-physical production potential is a satisfactory approach for pineapple production intensification.

“…The cultivar used influences plant size, nutrient absorption, dry matter production, fruit yield and dry matter accumulation in the different organs of the plant (Hanafi et al, 2009;Neri et al, 2021); which affects the concentration and accumulation of nutrients in each part of the plant (Sampaio et al, 2011;Trejo et al, 2020). Planting density is another factor that can affect the concentration of nutrients because it modifies the size of the plant; as the plantation density increases, the number of leaves emitted, the size of the stem and the size of the fruit are reduced (Cardoso et al, 2013;Souza et al, 2019). Although a smaller size and amount of dry matter is obtained from the plant in the highest planting density, the yield, and the amount of dry matter per hectare is greater as the planting density increases, consequently, the amount of nutrient extracted per hectare increases as the amount of dry matter produced increases (Souza et al, 2019).…”

Background. The amount of nutrients required by pineapple varies depending on the cultivar and planting density. Knowing the nutrient requirement in quantity and the appropriate phenological stage will allow the development of an adequate fertilization program. Objective. To determine the effect of pineapple cultivar and planting density on N, P, and K content during plant development and at harvest. Methodology. The cultivars 'Smooth Cayenne', 'Champaka', and 'MD-2' were established at 30000, 45000, and 60000 plants ha-1. Eight samples were taken to determine the N, P, and K content in the organs and the total plant. Results. The highest and lowest N, P, and K contents were detected in the leaf and root, respectively. The highest N and K contents occurred at 441 - 506 days after planting. Higher P content occurred close to harvest. The highest N, P, and K contents per plant were at 30000 plants ha-1 (14.86, 1.52, and 16.29 g plant-1, respectively) and the lowest at 60000 plants ha-1 (10.16, 1.13, and 14.6 g plant-1, respectively). Higher N, P, and K contents per hectare were detected with 60000 plants ha-1 (609, 68, and 875 kg ha-1, respectively). At harvest, ‘Smooth Cayenne’ at 60000 plants ha-1 accumulated the highest amount of N, P, and K (147, 37, and 306 kg ha-1, respectively). Implications. The changes that can occur in the nutrient requirements of pineapple as a function of cultivar, planting density, and stage of plant development were identified. This information will be useful for producers, agricultural technicians, and researchers in Mexico and the world, to generate fertilization programs or establish new research. Conclusion. At the beginning of plant growth, a higher N, P, and K contents in the leaf, this amount decreases as the fruit harvest approaches. Regardless of cultivar, the highest nutrient content per plant occurs at the lowest planting density, however, the highest content per hectare occurs at the highest planting density. At harvest time, fewer nutrients are removed from the soil with 'Champaka' and 'MD-2' fruit.
