“…High values were globally obtained with treatments which associated higher nitrogen and potassium doses. These results are comparable to those of [32], who observed an increase in pH of pineapple "Smooth Cayenne" under the influence of nitrogen and potassium. Similarly, [11] and [38] noted a reduction in juice acidity under the influence of increasing nitrogen rates.…”

“…These results are comparable to those of [32], who observed an increase in pH of pineapple Mulching associated with N-K fertilization had influenced positively the quality of sugarloaf pineapple and, as a result, had improved the percentage of fruit meeting European standards and standards for local consumption. Mineral and/or organic fertilizer effects on fruit quality attributes has been reported by some authors [12,[14][15][16][17]32,38], but the impact of pineapple residues on fruit quality was not explored.

“…To evaluate fruit acceptability for fresh local consumption, a principal components analysis followed by a hierarchical classification was performed with the package FactoMineR on the sensory and physico-chemical characteristics of fruits. The chemical parameters were considered as supplementary quantitative variables, because they are directly related to sensory characteristics [32,33]. For each sensory and physico-chemical characteristics class, we measured the difference between the values for class and overall values.…”

Residues Management Practices and Nitrogen-Potassium Fertilization Influence on the Quality of Pineapple (Ananas comosus (L.) Merrill) Sugarloaf Fruit for Exportation and Local Consumption

et al. 2017

Heterogeneity in pineapple fruit quality explains the low export volume of fruits from Benin to international markets. This work aims to investigate the influences of residues mulching or burying and N-K fertilization on (1) fresh fruit juice quality and the proportion of fruit meeting European standards and (2) fruit acceptability for fresh local consumption, as well as to identify morphological characteristics most related to fruit chemical quality attributes. The experimental design was a split-plot with three replications, where the main factor was N-K fertilization (T1 = 1.6 N and 1.6 K, T2 = 5.8 N and 6.6 K, T3 = 10 N and 11.6 K, T4 = 1.6 N and 11.6 K, T5 = 10 N and 1.6 K in g·plant −1 ) and the sub-plot factor was mulching with pineapple residues (no mulching = 0, surface mulching = 10, buried = 10 in t·ha −1 ). The results suggested that residues mulching and N-K fertilization has improved the percentage of fruit meeting European standards and local acceptability. The treatments T2B (T2 + burying) and T4B (T4 + burying) gave a higher proportion of fruits meeting European standards and were also promising for producing highly acceptable fruits by local consumers. Finally, the results revealed that the ratios of crown length: fruit length, crown length: infructescence length and crown length: median diameter were significantly associated with fruit quality, which has not yet been reported.

“…These authors hypothesized that this soil nutrient imbalance should limit not only yield but also fruit quality. The optimal combination of fertilizers (N, P and K) for Smooth cayenne juice oriented production has been carried out [11]. Most works on pineapple fertilization only specify the type or quantity of fertilizer for quality fruit production [11] [12] [13] [14] without linking fertilization to the goal of production.…”

Fertilization practices can influence the quality of pineapple fruit and consequently its acceptability by consumers who are increasingly oriented towards high quality agri-food products. This study aimed at evaluating the influence of N, P and K on some physico-chemical and organoleptic characteristics of pineapple (Ananas comosus L. Merr) for fresh consumption and juice processing. A complete NPK factorial design was installed in the south Benin. The treatments NPK in g plant-1 were randomized into four blocks: T1; T2; T3; T4; T5; T6; T7; T8; T9. Brix juice was determined using a refractometer and pH with a pH meter. An evaluation of sensory characteristics such as sweetness, acid taste and aroma of fresh pineapple pulp and processed juice was made by a panel of tasters selected and trained. A principal components analysis, followed by a numerical classification was performed on fruits' sensory and physicochemical characteristics. Results showed that juice pH was significantly influenced by the phosphorus and potassium. Potassium influenced significantly juice yield. Some physico-chemical characteristics and sensory attributes were correlated between them and groups of treatments are formed for both the juice and the fresh fruit.

Effect of Planting Density and K2O:N Ratio on the Yield, External Quality, and Traders' Perceived Shelf Life of Pineapple Fruits in Benin

et al. 2021

Quality, shelf life, and yield of a pineapple fruit are the important attributes for the producers and customers in the pineapple value chain of Benin, whereas poor quality, short shelf life, and low yield are the main constraints. We quantified the effects of planting density and K2O:N fertilizer ratio on the pineapple yield, external quality, and perceived shelf life in four on-farm experiments with cv. Sugarloaf in Benin; two experiments were installed in the long rainy season and two in the short rainy season. A split-plot design was used with the planting density as the main factor at three levels: 54,000, 66,600, and 74,000 plants.ha−1. The K2O:N ratio was a subfactor with three levels: K2O:N = 0.35 (farmers' practice), K2O:N = 1, and K2O:N = 2. The results showed that both factors had no effect on the crop development variables (such as the number of functional leaves and D-leaf length) at the moment of flowering induction. The planting density had no effect on the total weight per fruit, infructescence weight, total fruit length, infructescence length, crown length, or the fruit shelf life as perceived by traders. The yield increased from 54.9–69.1 up to 90.1 t.ha−1 with an increase in the planting density. The yield increase was not at the expense of the fruit weight. Increased K2O:N ratio led to a higher fruit weight whereas the fruit length was not affected. The shelf life of fruits produced at a K2O:N ratio of 1 and as perceived by traders was 6 days longer than that of fruits produced at a ratio of 0.35 (farmers' practice). Based on these results, we suggest the fresh pineapple farmers in Benin to use a combination of 66,600 plants.ha−1 with a K-fertilization scheme based on a K2O:N ratio of 1 to meet the expectation of both producers and customers in terms of fruit yield and fruit quality.
