“…Pois, de acordo com trabalho realizado por SOUZA et al (2011), o enxofre (S) é o quarto nutriente mais extraído pela cultura do alho. Apesar da similaridade nos teores de Ca e Mg na cinza e na cama de aviário (Tabela 1), e a superioridade no teor de K na cinza (Tabela 1), que segundo SOUZA et al (2011) é o segundo nutriente mais demandado pela cultura, os baixos teores de N e S, na cinza foram determinantes para a menor produtividade de alho nesse tratamento (Tabela 3).…”

“…The maximum estimated values were 41.23 cm, at 64 DAP; 46.78 cm, at 60 DAP; 61.13 cm, at 63 DAP; 54.01 cm, at 65 DAP; and 44.03 cm, at 61 DAP, at doses of 0, 40, 80, 120, and 160 kg ha -1 N, respectively ( Figure 1A). Souza et al (2011), working with the cultivar "Roxo Pérola de Caçador" in Lavras, MG, also verified a quadratic effect for plant height as a function of evaluation times, obtaining maximum height (81.1 cm) at 100 DAP. This quadratic behavior, observed in both studies, can be attributed to shoot senescence, indicating that during bulbification, a large part of leaf photoassimilates is redistributed to the bulbs.…”

Nitrogen fertilization for noble garlic production in high altitude regions of the Brazilian semiarid region

et al. 2019

View full text Add to dashboard Cite

Rio Grande do Norte State in Brazil has microregions with altitudes where the edaphoclimatic conditions are favorable to the cultivation of garlic, including vernalized noble garlic. An example is the municipality of Martins, where vegetable cropping is not a traditional practice. Since it is a region with potential for cultivation of noble garlic, comprising soil and climate conditions that are distinct from traditional production regions in Brazil, the use of nitrogen fertilization becomes an alternative to increase crop yield. This fact can stimulate the semiarid producer to invest in the crop, once it guarantees greater economic return. Thus, aiming to evaluate the production of vernalized noble garlic as a function of nitrogen doses applied in top dressing, an experiment was developed from May to August 2014, using a complete randomized complete block design with five replicates. The treatments consisted of the cover application of increasing doses of N (0, 40, 80, 120, and 160 kg ha-1). The following were evaluated: plant height; number of leaves; average bulb weight; total, commercial, and noncommercial bulb yield; bulb and bulblet classification; and number of bulblets per bulb. The dose of 90 kg ha-1 nitrogen, applied in top dressing, provided the highest averages of plant height, number of leaves, average bulb weight, and total bulb yield. The dose of maximum economic efficiency was 91 kg ha-1 , which promoted greater commercial bulb yield. The number of bulblets per bulb and bulblet classification were not influenced by nitrogen doses applied in top dressing.

“…However, despite improvements in the last years, the Brazilian garlic production is still insufficient to supply the domestic market demand, which are met by imports from other countries, mainly China, Argentina, and Spain (IBGE, 2017). However, the addition of new technologies, such as the use of improved cultivars, vernalization, and mainly the adoption of virus-free clove-seeds has significantly increased the bulb yield and quality of garlic plants in Brazil, and the crop expansion to other regions of the country (SOUZA et al, 2011).…”

Clove-Seed Size and Health and Plant Spacing on the Viability of Garlic Crops

et al. 2021

Garlic is a vegetable that has a high economic importance for Brazil. However, despite increases in garlic bulb production in the last years, Brazil is still dependent on imported garlic to meet the national demand. Thus, proper management practices and the use of virus-free clove-seeds are promising alternatives to ensure a high productivity and profitability. Thus, the objective of this work was to evaluate production characteristics and profitability of conventional and virus-free garlic crops as a function of different clove-seed sizes and plant spacings. Two experiments were conducted simultaneously, using virus-free and conventional garlic plants in Portalegre, state of Rio Grande do Norte, Brazil, in a randomized block experimental design, with four replications. The treatments were arranged in split-plot, with the clove-seed size (large and small) in the plots, and the spacing between plants (7.5, 10.0, 12.5, and 15.0 cm) in the subplots. The combination between the use of virus-free clove-seeds, large clove-seed size, and spacing of 12.5 cm between plants resulted in the highest commercial bulb yield and net income, R$ (BRL) 85,151.00 ha-1. The use of large clove-seeds and spacing of 7.5 cm between plants are recommended for conventional garlic crops.
