“…The number of rhizomes per plant was higher than the averages obtained by Colombo et al (2018), who reported 8.4 rhizomes per taro plant in intercropping with cucumber, and 11.3 rhizomes per taro plant in monoculture. According to the authors, the habit of indeterminate growth and tutored cultivation of cucumber promoted shading of taro plants for approximately two months, resulting in an average reduction of 29% in the production of commercial rhizomes.…”

“…Vieira et al (2014) reported a mean fresh mass of 53.9 grams rhizome -1 in the cultivation of taro intercropped with snap bean. Colombo et al (2018) observed a mean fresh mass of 30.5 grams rhizome -1 in taro and cucumber intercropping.…”

“…However, its long cycle, from 7 to 9 months, may impair the cultivation by small farms. Thus, taro intercropped with other vegetables that result in anticipated harvests may be an alternative for allowing economic returns throughout the cycle of the species (VIEIRA et al, 2014;BRITO et al, 2017;COLOMBO et al, 2018).…”

This work aimed to evaluate the technical feasibility of lettuce, Indian spinach and taro intercropping under organic fertilizer. The experiment was performed at Água Limpa Farm, belonging to the University of Brasília, located in Brasília - DF, from October 2014 to June 2015. A completely randomized block design with seven treatments and four replications was used. Each experimental plot had 18 m2 (4.5 m x 4.0 m), totaling 28 plots. The following treatments were assessed: lettuce monoculture, Indian spinach monoculture, taro monoculture, lettuce/Indian spinach intercropping, lettuce/taro intercropping, Indian spinach/taro intercropping, and lettuce/Indian spinach/taro intercropping. In all treatments, the following spacings were used: 0.25 x 0.25 m (lettuce), 1.0 x 0.6 m (Indian spinach), and 1.0 x 0.3 m (taro). Crop production was evaluated from sample plants taken from the central part of each plot. Two harvests of lettuce, two of Indian spinach and one of taro were carried out during intercropping. In the first cycle, lettuce highest mean yield values were observed in the lettuce monoculture (3.5 kg m-2) and lettuce/Indian spinach intercropping (3.4 kg m-2). The crop reached the commercial size in both production cycles, except when intercropped with Indian spinach in the second cycle. The highest Indian spinach mean fresh mass was recorded in the lettuce/Indian spinach intercropping (974.7 g plant-1; first harvest) and monoculture (327.5 g plant-1; second harvest). The yield of taro rhizomes was significantly higher when intercropped with lettuce, showing a mean value of 16.8 kg m-2. The intercropping arrangements with lettuce increased yield of nonconventional vegetables. The conventional and nonconventional vegetables’ intercropping technique increased species diversity in the area without interfering in the agronomic performance and quality of the crops.

“…The increase in the quantum yield of non-regulated photochemical quenching (Y NO ) observed in the T143 treatment is a strong indication of the occurrence of photoinhibition in this treatment, since the Y NO values are negatively correlated with the quantum photochemical efficiency of PSII, which makes it an excellent indicator of photodamage (Colombo et al, 2018). This photodamage may be related to the H 2 O 2 concentration used (75 μM), indicating that at this dose H 2 O 2 became toxic to 'BRS Verde' cotton, since high concentrations of this reactive oxygen species induce oxidative stress, causing lipid peroxidation and destroying cellular integrity and pigments, leading to death (Zhang et al, 2014).…”

The objective of this study was to evaluate the quantum yield and concentrations of photosynthetic pigments of naturally colored cotton genotypes under irrigation with waters of different electrical conductivities and foliar applications of hydrogen peroxide. The design used was randomized blocks in a 4 × 3 × 2 factorial arrangement, corresponding to four concentrations of hydrogen peroxide - H2O2 (0, 25, 50 and 75 μM), three genotypes of colored fiber cotton (‘BRS Rubi’, ‘BRS Topázio’ and ‘BRS Verde’) and two values of electrical conductivity of water (0.8 and 5.3 dS m-1), with three replicates. Irrigation with water of 5.3 dS m-1 reduces the chlorophyll a, chlorophyll b and total chlorophyll concentrations of ‘BRS Rubi’ cotton. The concentrations of photosynthetic pigments, maximum fluorescence, variable fluorescence and quantum efficiency of photosystem II of ‘BRS Rubi’ cotton increased under irrigation with 0.8 dS m-1 water and foliar application of 50 μM of hydrogen peroxide. Water of 5.3 dS m-1 and foliar applications of 75 μM of hydrogen peroxide reduce the concentrations of photosynthetic pigments, but did not cause damage to the efficiency of photosystem II of the colored cotton genotypes.

“…Studies that evaluated the rate of return and profitability index in horticulture show a great variability in the values found. For the cucumber crop, which belongs to the same family of bur gherkin, rate of return values ranging from 1.19 to 1.39 and profitability index values from 15.75 to 27.84 % were obtained, when cultivated with 30 cm distanced plants or two 60 cm distanced plants (Colombo et al 2018). In the cultivation of Italian zucchini, also a species belonging to the cucurbit family, rate of return values from 4.64 to 4.82 and profitability index values from 78 to 79 % were obtained (Fukushi et al 2018).…”

The bur gherkin cultivation is predominantly carried out without a staking system, but problems such as the "white belly" and fruit rot occur in this system. This study aimed to evaluate staking systems for bur gherkin plants. The experimental design was randomized blocks, with five treatments (no staking, agricultural netting staking, Mexican staking, vertical ribbon with total secondary stem thinning and vertical ribbon with alternate secondary stem thinning) and four replicates. The fresh mass and number of fruits per plant, fruit length and average diameter, number and fresh mass of fruits with white belly per plant, fresh mass per fruit and total yield were evaluated, as well as the economic indicators gross income, net income, rate of return and profitability index. For all the staking systems, the incidence of fruits with white belly was lower. The agricultural netting (43.75 t ha-1), Mexican (35.94 t ha-1) and vertical ribbon with alternate secondary stem thinning (22.24 t ha-1) systems promoted yields superior to that for no staking. The best economic indicator (US$ 21,031.46 ha-1) was observed for the agricultural netting staking, which is the most recommended for the bur gherkin cultivation.
