“…Such result was also reported by Silva et al (2014). The influence of fertilization on yield is demonstrated by Stewart et al (2005), who analyzed results of 362 crop production seasons and verified that 30 to 50% of the yields of the evaluated crops are attributed to nutrients of commercial fertilizers containing mainly N, P and K. Silva et al (2013) claim that the addition of NPK and NP fertilization resulted in improvement of the nutritional quality of cactus pear and, at the spacing of 1.00 x 0.50 m, in the increase of dry matter production, at 620 days after planting. Santos et al (2006) highlight that organic or mineral fertilization can increase by more than 100% cactus pear production and that, two years after planting, the dense cultivation promoted production of 250 to 300 Mg ha -1 of green matter, but it requires high fertilization levels and greater care with respect to cultural practices.…”

“…This result can be explained by the small addition promoted by the NPK treatments (100 kg ha -1 of K 2 O). According to Silva et al (2013), such added amount of K is insufficient to alter significantly K contents in the tissues. Furthermore, the soil already has, before planting, mean content of (2011), respectively.…”

“…Plant population must vary according to soil fertility, amount of rainfall, type of exploration and species or cultivar used. Spacing and fertilization managements can improve the use of radiation and the nutritional status of plants (Blanco-Macías et al, 2010) with the increment in photosynthetic rate, growth, yield and, consequently, in the nutritional value of the produced forage (Silva et al, 2013;Donato et al, 2014b). Espinoza et al (2008), working with five cultivars in Mexico, reported that significant increases in the production of green and dry matter can be obtained with the use of dense plantation.…”

This work aimed to evaluate extraction/ export of nutrients and dry matter production in the 'Gigante' cactus pear, grown in different spacings and fertilizations 620 days after planting. Twelve combination of treatments were used consisting of: three spacings - 1.00 x 0.50; 2.00 x 0.25; and 3.00 x 1.00 x 0.25 m, and four fertilizations - 000-000-000; 000-150-000; 200-150-000; and 200-150-100, kg ha-1, of N, P2O5 and K2O, in a 3 x 4 factorial scheme in a randomized block design, with three replicates. Extraction/export of N, P, K, S, Ca, Mg, B, Fe, Mn, Zn, Na and Cu were determined and the means were 304.35; 18.81; 421.04; 62.35; 464.63; 215.77; 0.39; 0.81; 23.74; 1.11; 0.62 and 0.08 kg ha-1, besides the mean dry matter production of 17.11 Mg ha-1. There were significant interactions for extraction/export of Mg and dry matter production. The fertilizations used were insufficient to meet the demand of N, K, Ca, Mg, S and micronutrients. Fertilization increased the extraction of nutrients, particularly N, P and S at the spacing of 1.00 x 0.50 m, and increased dry matter production. The decreasing order of extraction/export was Ca, K, N, Mg, S and P for macronutrients and Mn, Zn, Fe, Na, B and Cu for micronutrients.

“…Silva et al (2012) evaluated mineral fertilization and found 2,006.0 mg kg -1 of Mn, well above the sufficiency range (260.0 to 507.7 mg kg -1 ) (DONATO et al, 2017b). Silva et al (2016) found 3-fold the Mn exported by the plant, using ammonium sulfate as N source, which reduces the pH and, thus, increases the solubility and absorption of Mn 2+ . This was observed by the pH decrease from 5.3 (before planting) to 4.3 (harvest time), when using ammonium sulfate as N source.…”

Establishment of Dris Norms for Cactus Pear Grown Under Organic Fertilization in Semiarid Conditions

The objective of this work was to establish DRIS norms for evaluation of nutritional status of cactos pear of the Gigante cultivar grown under organic fertilization in semiarid conditions. Cladode macro and micronutrient contents and dry matter yield of 72 plots were evaluated. The experiment was conducted in a randomized block design with three replicates, using a 4×3×2 factorial arrangement consisted of four bovine manure rates (0, 30, 60, and 90 Mg ha-1 ano-1), three spacings (1.00×0.50, 2.00×0.25, and 3.00×1.00×0.25 m), and two production cycles (600 and 930 days). The data were separated into high-yield population (HYP) and low-yield population (LYP), above and below 19.93 Mg ha-1 cycle-1, respectively. The mean, standard deviation, coefficient of variation, variances, and variance ratios of all bivariate relations between nutrients were calculated for the establishment of DRIS norms, considering the direct (A/B) and reverse (B/A) form. The selection of direct and reverse relations between nutrients to compose the DRIS norms was based on the variance ratio between LYP and HYP (S2b/S2 a). The sixty-six relations between cladode nutrient contents that presented the higher ratios between the variances in the LYP and HYP (S2b/S2a) were chosen. The DRIS norms established make viable the use of leaf diagnosis as an evaluation method of nutritional status of cactos pear of the Gigante cultivar grown under organic fertilization in semiarid conditions.

The objective of this study was to evaluate nutrient concentration and nutritional efficiency in ‘Gigante’ cactus pear under different chemical, organic and organomineral fertilizations, planting configurations and spacings, during three production cycles. Seventy two treatments, involving two types of configuration in the plots, three spacings in the subplots and 12 types of fertilization in the sub-subplots were arranged in a split-split-plot scheme, in a randomized block design, with three repetitions. At the time of harvest of each production cycle, 40 cladode tissue samples were collected per treatment to determine dry matter mass and nutrient concentration, which were used to calculate the coefficients of biological utilization of nutrients. Organic fertilization reduces Mn concentrations in cladodes to levels below the sufficiency range. The nutritional efficiency of N, S, P, Mn and Zn is higher with organic and organomineral fertilizations and are associated with higher dry matter yields, whereas K nutritional efficiency is higher with mineral fertilization. The absence of fertilization or application of 30 Mg ha-1 year-1 of bovine manure is insufficient to ensure nutritional status and dry matter yield above 15 Mg ha-1 in ‘Gigante’ cactus pear.
