“…During the day, malic acid moves to the cytoplasm and is decarboxylated by malic enzymes or phosphoenolpyruvate carboxykinase enzymes, and CO 2 is mostly converted to hexoses through the Calvin cycle or gluconeogenesis pathway [34,35]. However, under favorable environmental conditions such as a suitable temperature, humidity (both soil and air), and light intensity, pineapple can easily switch its metabolism to facultative C3/CAM [36,37]. Light intensity is a determining factor, as demonstrated when the pineapple plants were subjected to the C3 (40 µmol m −2 s −1 ) or CAM (260 µmol m −2 s −1 ) conditions; the C3 plants showed a lower leaf thickness, leaf area, fresh and dry weight, net photosynthesis rate, and sucrose content [33], which is consistent with our results.…”

The use of organic sources presents itself as a viable alternative to mitigate the excessive reliance on chemical fertilizers in agricultural practices. However, in the realm of pineapple cultivation, research exploring the synergy between chemical and organic fertilizers remains scarce. In this context, the objective of this research was to evaluate the impact of the combination of chemical and organic fertilizers on the growth and yield of the MD-2 pineapple cultivar under two shade net conditions (installed 45 and 250 days after planting). The experiment was conducted in a split-plot design, with the main plot being the shade net conditions and the sub-plots the five fertilization treatments, which were applied 18 times via drip irrigation (control, 100% chemical fertilization, 50% reduced chemical fertilization, organic fertilization, and a combination of 50% chemical fertilization with organic fertilization). The results showed that the early installation of shade netting 45 days after planting decreases the growth and yield of pineapple; thus, the use of shade netting at this age is not recommended. Regarding fertilization, the combination of 50% chemical fertilization with organic fertilization showed similar growth and yield values compared to 100% conventional chemical fertilization under both shade net conditions. Furthermore, this combination presented similar nitrate and potassium values in the plant and did not negatively affect malic acid content. Therefore, the use of organic fertilizers in pineapple cultivation is a promising strategy to reduce the excessive use of chemical fertilizers, and it could also improve soil fertility.

“…Irrigation water quantity, quality (Guimaraes et al, 2016;Brito et al, 2017) and method of irrigation influences the photosynthetic efficiency of pineapple (Souza et al, 2012;Maia et al, 2016). The high photosynthetic efficiency of pineapple is due to the Crassulacean Acid Metabolism (CAM) (Zhang et al, 2014;Couto et al, 2016).…”

The experiment was conducted at the research farm of ICAR- Central Coastal Agricultural Research Institute, Goa, India during 2016–2019 to estimate the crop water requirement (CWR) of pineapple during different growth stages and compare the pineapple crop performance and economic viability at different irrigation systems. Crop water requirement of pineapple was calculated based on the consolidated weather data of 14 years and crop evapotranspiration (ETc) of pineapple at different growth stages using Penman-Montieth equation using CROPWAT 8.0 software. In the experiemtal location, maximum crop evapotranspiration was found in the month of May (81 mm month-1) and the minimum was in the month of July (25 mm month-1). Crop water requirement was the highest in April (0.67 litre day-1 plant-1). During the period of monsoon, irrigation was withdrawn due to sufficienct soil moisture situation. Performance of pineapple crop under different systems of irrigation viz., surface irrigation, drip irrigation and drip fertigation was studied and found that the highest plant height (76.90 cm), D leaf width (5.45 cm), number of leaves (43), D leaf weight (150.3 g) and fruit weight (2.35 kg) were in drip fertigation. An estimated yield of 96.80 t ha-1 was recorded under drip fertigation treatment followed by drip irrigation (90.99 t ha-1) and surface irrigation (76.45 t ha-1) treatments. The cost economics analysis of pineapple production under different treatments revealed that the highest gross returns (` 14.5 lakhs), net returns (` 7.9 lakhs) and B:C ratio (1.2) were in drip fertigation treatment. Adoption of drip fertigation system in pineapple crop under west coast agro-climatic conditions of Goa is helpful to enhance the crop growth and yield of pineapple and fetch good economic returns.

“…In this context, the pineapple can become an alternative crop for other semiarid regions (Mota et al, 2016) since it has the potential of maintaining its yield under hotter and drier climates (Borland et al, 2014) owing to its crassulacean acid metabolism (CAM) (Zhang et al, 2014;Couto et al, 2016). CAM plants save water by closing their stomata during the day and opening them during the night with CO2 fixation, resulting in better water-use efficiency in dry conditions (Carr, 2012).…”

“…Studies about physiological characteristics of pineapple in regard to fluorescence were mainly carried out in controlled environments such as greenhouses and laboratory, in vitro, using only plantlets (Vieira et al, 2010;Cruz et al, 2014;Couto et al, 2016). Thus field research into chlorophyll fluorescence comprising the whole pineapple cycle is much needed.…”

Studies determining physiological characteristics of field-grown pineapples irrigated with low-quality water are lacking. This work evaluated the photochemical efficiency of ‘Pérola’ pineapple irrigated with saline water in the semiarid region of Bahia, Brazil. The experiment was carried out in randomized blocks with five treatments consisting of the following irrigation depths: 100% of ETc using water with electrical conductivity (ECw) of 0.75 dS m-1; and 50, 75, 100 and 125% of ETc using water with ECw of 3.6 dS m-1. Chlorophyll a fluorescence measurements were made over the course of 13 months using a pulse-modulated fluorometer, in all treatments. Quantum efficiency (Fv/Fm) fluctuated throughout the cycle of the pineapple with values below the ideal, especially at the end of the crop cycle. Quantum yield of photosystem II (Yield), photochemical quenching (qP), non-photochemical quenching (NPQ) and chlorophyll fluorescence decrease ratio (RFd) were not influenced by irrigation depths. Therefore, energy used for photosynthetic processes in pineapple plants is not affected by irrigation using saline water with electrical conductivity of 3.6 dS m-1.
