“…Pineapple cropping is dominated by conventional monocropping with high levels of agrochemical inputs (Loeillet, 2013) due to nitrogen (N) and potassium (K) fertilisation (Dorey et al, 2015;Teixeira et al, 2011), weed management, crop protection and flowering induction. This intensive monocropping is known to increase tropical soil depletion, pollution and erosion (Animesh and Chaudhuri, 2014;Echeverria-Saenz et al, 2012;Khamsouk and Roose, 2003).…”

SUMMARYFruit and vegetable farming generally involves high levels of chemical inputs despite the fact that consumers are increasingly concerned about the sanitary and organoleptic aspects of fruit quality. Pineapple is largely subject to these issues since it is dominated by conventional monocropping with high levels of agrochemical inputs due to nitrogen (N) and potassium (K) fertilisation, weed management, crop protection and flowering induction. However, low-input pineapple cropping systems are both rare and little documented. Our study aimed at replacing all or part of the chemical fertilisers used with local organic fertilisers. It was conducted on the cultivar 'Queen Victoria', without pesticides or herbicides, in Reunion Island. We compared the impacts of three fertilisation treatments on pineapple growth and yield, fruit quality traits, symptoms of two major fungal diseases in fruit and production costs and labour times: (i) conventional: NPK fertiliser at recommended doses (265.5 kg ha −1 N-10.53 kg ha −1 P-445.71 kg ha −1 K); (ii) integrated: Mucuna pruriens green manure (240.03 kg ha −1 N, 18.62 kg ha −1 P, 136.11 kg ha −1 K) incorporated into the soil and a half-dose of NPK fertiliser and (iii) organic: M. pruriens green manure incorporated into the soil and foliar applications of sugarcane vinasse from a local distillery, rich in K (14.44 g L −1 ). Our results showed that NPK fertilisation could be replaced by organic fertilisers as well as by integrated fertilisation. 'D'-leaf analysis showed that vinasse supplies a largely sufficient K level for growing pineapples. With organic fertilisation, pineapple growth was slower, 199 days after planting vs. 149 days for integrated or conventional fertilisations, and fruit yield was lower, 47.25 t ha −1 vs. 52.51 and 61.24 t ha −1 , probably because M. pruriens green manure provided an early increase in soil mineral N, whereas N requirements are much higher four months after planting. However, the fruit weight (709.94 ± 123.53 g) was still within the size range required for the export market (600-900 g). Interestingly, organic fertilisation significantly reduced Leathery Pocket disease and produced the best quality fruit with the highest total soluble solids contents (TSS) and the lowest titratable acidity (TTA). Fruit quality was also significantly improved with integrated fertilisation, with fruit weight similar to that of conventional fertilisation. To conclude, these findings have implications for the sustainability of pineapple production and could lead to low-input innovative cropping systems that reduce production costs and develop local organic inputs.

Fruitlet Core Rot (FCR) is a fungal disease that negatively impacts the quality of pineapple, in particular the ‘Queen Victoria’ cultivar. The main FCR causal agent has been identified as Fusariumananatum. This study focused on the correlation between FCR disease occurrence, fungal diversity, and environmental factors. FCR incidence and fungal species repartition patterns were spatially contextualized with specific surrounding parameters of the experimental plots. The mycobiome composition of healthy and diseased fruitlets was compared in order to search for potential fungal markers. A total of 240 pineapple fruits were sampled, and 344 fungal isolates were identified as belonging to 49 species among 17 genera. FCR symptom distribution revealed a significant gradient that correlated to that of the most abundant fungal species. The association of wind direction and the position of proximal cultivated crops sharing pathogens constituted an elevated risk of FCR incidence. Five highly represented species were assayed by Koch’s postulates, and their pathogenicity was confirmed. These novel pathogens belonging to Fusariumfujikuroi and Talaromycespurpureogenus species complexes were identified, unravelling the complexity of the FCR pathosystem and the difficulty of apprehending the pathogenesis over the last several decades. This study revealed that FCR is an airborne disease characterized by a multi-partite pathosystem.

The gains obtained from organic mulching of pineapple farms can never be overemphasized. Despite this fact many developed countries still patronize synthetic mulching due to its efficiency in large pineapple farms. However in developing countries of Africa and Nigeria in particular where small scale pineapple farmers still contribute to the national gross domestic product (GDP), the need for cheaper organic mulching techniques which do not only suppress weed and improve soil fertility but have positive influence on pineapple flowering, ripening and suckering is required. Based on this, a research was carried out at the Teaching and Research Farm, Federal University of Technology Owerri to assess the effect of some selected organic mulch types on the maturing trends of Smooth Cayenne pineapple. A 32 factorial fitted into a Randomized Complete Block Design (RCBD) with three replications was used. Result showed that main effects from mulch rates and mulch types independently had significant influence on days to first flowering, days to 50% flowering, the interval between time of first flowering and attainment of 50% flowering, days to ripening, interval from flowering to ripening and number of suckers produced at 50% flowering stage while interaction of mulch rates and mulch types only had significant effect on days to first flowering. This study revealed that the utilized organic mulch materials had tremendous positive influence on flowering, ripening and suckering of Smooth Cayenne pineapple.
