“…The linear increase in K levels available in the soil was expected because this element was used in increasing quantities with the fertilizations (Figure 5), similar to the results obtained by Almeida, Corrêa, Crisostomo, Araújo, and Silva (2014).…”

<b>Improvement of production and fruit quality of pitayas with potassium fertilization

Pitaya is a fruit that is becoming promising for cultivation around the world due to the quality of its fruits in terms of taste and their peculiar external shape. Because it is a recenttly cultivated crop, information about fertilization is essential to enable its production. In this sense, this study was performed aiming to evaluate different doses of K 2 O for pitaya cultivation. Hylocereus undatus and Hylocereus polyrhizus were studied under field conditions. Pitayas were cultivated at a 3 × 3m spacing, and four doses of K 2 O were tested: 0, 50, 100, and 200 g plant-1 , with a 2 × 4 factorial arrangement distributed in a randomized block design. The production per plant (kg and number of fruits) was evaluated in the

“…Soil fertilizers were applied using the nutrient rates recommended by Almeida et al (2014) and Corrêa et al (2014) for pitaya crops, which were 750 (N), 375 (P), 375 (K) and 10 (Zn) mg dm -3 . The nutrient source used were urea (46% N), simple superphosphate (18% P 2 O 5 , 25% CaO and 12% S), potassium chloride (62% K 2 O) and FTE BR-12 (a granulated mixture of micronutrients containing 9% Zn, 1.80% B, 0.80% Cu, 2% Mn, and 0.10% Mo).…”

“…According to Luders and Mc Mahon (2006), nitrogen is required by pitaya during the whole vegetative growth stage, and is responsible for the emission of new cladode buds. Almeida et al (2014) found that increases in N accumulation in pitaya (Hylocereus undatus) cladodes is induced by increasing N application rates.…”

“…Fernandes et al (2018), evaluated the production and quality of pitaya fruits grown on soils with potassium fertilizer applications and found that the application of 106 to 133 g of K 2 O per plant in the first growth year and 200 g of K 2 O in the second and third year increases the production and quality of white-fleshed (Hylocereus undatus) and red-fleshed (Hylocereus polyrhizus) pitaya fruits. In addition, the use 150 to 225 mg dm -3 of P, 4 to 6 mg dm -3 of Zn (CORRÊA et al, 2014), 300 to 450 mg dm -3 of N, and 150 to 225 mg dm -3 of K (ALMEIDA et al, 2014) results in a better growth of white-fleshed pitaya (H. undatus) seedlings.…”

Initial Growth and Nutrient Accumulation in Pitaya Plants at Different Phenological Stages1

et al. 2021

Information on nutritional management of pitaya crops are scarce. However, understanding the growth and nutrient accumulation in these plants at different developmental stages can assist in the development of rational soil fertilizer application programs for pitaya crops and decrease production costs. Thus, the objective of this work was to evaluate the growth and nutrient accumulation in pitaya plants throughout the crop cycle. Cladodes of pitaya plants of the Hylocereus setaceus species were grown in polyethylene pots containing a Typic Hapludult (Argissolo Vermelho-Amarelo Eutrófico) under full sun. The treatments consisted of six sampling times: 0, 60, 120, 180, 240, 300, and 360 days after planting (DAP). A randomized block experimental design with four replications was used. Four plants were sampled and evaluated for growth and nutrient accumulation at each sampling time. The pitaya plants presented an exponential growth up to 360 DAP and high nutrient absorption between 300 and 360 DAP. The nutrient and Na accumulations in the cladodes, in decreasing order, were: 3.91 (K), 2.56 (Ca), 1.95 (N), 1.24 (P), 0.45 (Mg), 0.30 (S), and 0.06 (Na) g plant-1, and 14.86 (Zn), 12.72 (Fe), 12.37 (Mn), 5.37 (B), and 1.04 (Cu) mg plant-1. The highest relative growth rate and relative nutrient absorption rate were found between 60 and 120 DAP.

“…The study showed a positive response as a result N and P fertilizer applied lead to induce shoot growth and this result in line with Moreira et al (2016) revealed that the number of shoots significantly increased compared with without fertilizer application. Almeida et al (2014) stated that there was the interaction N and P in the root and shoot parameters and enhanced the early growth of dragon fruit (Hylocereus undatus). In addition, the number of branchs and shoot heights increased as a result application of NPK fertilizer compare to the control (Kumar et al, 2018).…”

Nitrogen and Phosphorus fertilizers are required to enhance the plant growth and yield. The appropriate nitrogen and phosphorus doses on the growth and yield of dragon fruit (Hylocereus polyrhizus) are not well known. A study to evaluate the effect of nitrogen and phosphorus fertilizers on the growth and yield of dragon fruit (Hylocereus polyrhizus) was arranged in a completely randomized block design with two factors and three replications. The treatments consisted of four nitrogen doses (0, 50, 75 and 100 g-1pillar) and four phosphorus doses (0, 50, 75 and 100 g-1pillar). Growth and yield were significantly (p < 0.01) affected by increasing nitrogen and phosphorus doses and showed interaction on the number of shoots, number of flowers, and fruit sets. The number of shoots increased from around 102.98 to 162.10 % at nitrogen dose 100 g and phosphorus doses 50, 75 and 100 g compared with no treatment. Nitrogen dose at 100 g and phosphorus dose at 100 g produced 152.64 % more number of flowers compared to 0 g phosphorus. The fruit set increased by 58.32% at dose of 50 g nitrogen and 50 g phosphorus. Nitrogen applied at 100 g compared with 0 g nitrogen and phosphorus at different phosphorus doses increased in the number of fruits were 139.35 % and 13.56 - 58.15 %. Individual fruit weight among nitrogen doses and TSS among nitrogen and phosphorus doses showed no significant difference. Application of nitrogen fertilizer at 50 g-1pillar and phosphorus at 75 g-1pillar produced maximum yield, respectively, and thus, it should be recommended as optimum doses.
