“…The ornamental pineapple is a tropical plant of importance in the agribusiness of flowers and ornamental plants (LIMA et al, 2017). Due to its exotic appearance, abundance of colours and longevity, the crop has varieties (e.g.…”

“…As it is a new activity, the commercial production of potted ornamental pineapple lacks information on the use and management of production factors. Existing information, besides not being exclusive to the variety erectifolius, is scarce and restricted to a few topics, such as genetic improvement, fertilisation, nutrition and physiology (REIS et al, 2007;MENDES et al, 2011;HAWERROTH et al, 2014;SOUZA et al, 2014;VIÉGAS et al, 2014;BARBOSA et al, 2015;LIMA et al, 2017).…”

Irrigation Intervals in the Production of Ornamental Pineapple in Pots1

Information on irrigation management is essential in a production system for the commercial cultivation of ornamental pineapple in pots. As such, this work evaluated the effects of irrigation interval on the growth and production of the crop in pots. The experiment was carried out from 16/07/2015 to 21/05/2016 in a greenhouse located in Fortaleza, in the state of Ceará, Brazil. The experimental design was completely randomised, with five treatments, four replications and four plants per plot. The treatments consisted of irrigation intervals of 2, 4, 6, 8 and 10 days. The plants were grown in one-litre pots, fertilised with slow release fertiliser and subjected to supplementary drip irrigation. The following variables were analysed at the end of the cycle (402 days): number of leaves; length and width of the 'D' leaf; diameter of the rosette; plant height; rate of flowering; length and diameter of the peduncle, syncarp and crown; crown to syncarp ratio; and percentage of commercial plants. The irrigation interval influenced the number of leaves, length of the 'D' leaf, diameter of the rosette, plant height, rate of flowering and percentage of commercial plants. Irrigating every two days resulted in water savings, increased leaf growth and a high rate of flowering, and the greatest percentage of commercial plants. Irrigating at intervals of between four and 10 days, increased water wastage, and reduced leaf growth, the rate of flowering and the percentage of commercial plants. The shortest irrigation interval is therefore the most recommended for cultivation in pots.

“…Among tropical ornamental plants commercialised both domestically and internationally, the ornamental pineapple is important. This importance can be explained by its exotic appearance, durability (Costa Junior et al, 2016;Lima et al, 2017) and use in the flower and foliage, landscaping and gardening, and potted-plant sectors (Souza et al, 2012;.…”

“…As this is a method of farming recently adopted by producers, there is little information on quantifying or managing the factors of production. Existing research, besides not being specific to the variety erectifolius, is basically concerned with genetic improvement (Taniguchi et al, 2015;Lima et al, 2017), mineral nutrition (Hawerroth et al, 2014;Viégas et al, 2014;Barbosa et al, 2015) and plant physiology (Reis et al, 2007;Mendes et al, 2011).…”

The production of ornamental pineapple in pots under different drip-irrigation depths

et al. 2020

The production of ornamental pineapple in pots under different drip-irrigation depths 1 The objective of this work was to evaluate the effects of irrigation depth on the commercial production of ornamental pineapple in pots. The experiment was carried out in a greenhouse located in Fortaleza, in the state of Ceará, Brazil. The experimental design was completely randomised, with five treatments and four replications. The treatments were irrigation depths estimated at 50, 75, 100, 125, and 150% of the evapotranspiration of a crop of edible pineapple. The plants were grown in one litre pots, with supplementary irrigation every two days. The variables evaluated were: number of leaves; length and width of the 'D' leaf; diameter of the rosette; plant height; rate of flowering; length and diameter of the peduncle, syncarp and crown; crown to syncarp ratio; commercial productivity and water-use efficiency. An increase in irrigation depth produced a linear increase in the number of leaves, width of the 'D' leaf and rosette diameter, but had no effect on the other variables. Water-use efficiency decreased linearly with the increases in irrigation depth. Despite influencing leaf growth, each irrigation depth results in plants suitable for commercialisation in pots. The smallest irrigation depth gives the greatest economy and water-use efficiency.

“…The development of new cultivars requires agronomic, phytosanitary and postharvest evaluations, to select hybrids with commercially important traits that are also resistant to the main crop pests and diseases (Souza et al 2009a, Souza et al 2014, Souza et al 2019. The main commercial characteristics of ornamental pineapple, according to market standards, are a deformation-free peduncle (fruit-supporting stem), longer than 40 cm, and attractive and wellformed infructescences (Souza et al 2014, Lima et al 2017.…”
