“…Igbadun and Oiganji (2012), Ramalan, Nega, and Oyebode (2010) and Ribeiro et al (2016) observed that irrigation depths had similar effects on the yield of onion bulbs. The reduction in irrigation depth of 36% (321 to 204 mm) in 2014 and of 37% (444 to 278 mm) in 2015 resulted in losses of 29, 30, 33, and 11% and 38, 38, 34, and 17% in TY, MBFW, MBDW and MBD, respectively, in each year.…”

“…In 2015, irrigation had an opposite effect, as a larger percentage of bulbs had diameters greater than 60 mm. The highest number of bulbs was included in this classification, as found by Ricci et al (2014) and Ribeiro et al (2016). The increase in water deficit favored an increase in the percentage of bulbs with diameters between 30 and 40 mm (smaller class) and with diameter smaller than 30 mm (without commercial value) ( Figure 5).…”

“…Evaluating the onion yield under the same edaphoclimatic conditions but with different soil covers and irrigation depths, as estimated through the soil water balance with a TDR, Ribeiro et al (2016) obtained water depths of 372 and 351 mm (100% of crop evapotranspiration) in the absence and presence of soil cover, respectively. Marouelli, Abda, Madeira, Silva, and Oliveira (2010), in a study conducted in Brasília during the dry season of 2007, applied water depths of 525 and 625 mm in onion cultivation (cv.…”

“…It is considered the third most important vegetable in economic value in Brazil (Cecílio Filho, May, Pôrto, & Barbosa, 2009). It is the main agricultural activity of more than 60 thousand families, and almost 100% of its production area is subjected to irrigation, except in the south region of the country (Ribeiro, Carvalho, Santos, & Guerra, 2016).…”

“…O cultivo orgânico de hortaliças com o uso de cobertura morta sobre a superfície do terreno vem sendo empregado e tem proporcionado aumento de produtividade sem impactar os custos de produção (CARVALHO et al, 2018). Além de disponibilizar nutrientes às plantas, minimizando o uso de fertilizantes minerais (EGODAWATTA; SANGAKKARA; STAMP, 2012), o cultivo sobre palhada reduz a perda de água por evaporação, proporcionando aumento na eficiência do uso da água (RIBEIRO et al, 2016). Essa técnica vem sendo adotada por agricultores no cultivo do repolho, porém há poucas informações sobre a necessidade hídrica da cultura nessas condições (KADYAMPAKENI, 2013).…”

E-mail: vinirp.04@gmail.com *Extraído da dissertação de Mestrado do primeiro autor, defendida pelo Programa de Pós-Graduação em Engenharia Agrícola e Ambiental da Universidade Federal Rural do Rio de Janeiro 1 Resumo Objetivou-se estimar a evapotranspiração da cultura (ETc) e os coeficientes de cultivo (Kc) para as fases de desenvolvimento do repolho Fuyutoyo, utilizando lisímetro de pesagem. O experimento foi realizado de 17/07 a 26/10/2015, em área cultivada com repolho Fuyutoyo sobre a palhada de milho, no município de Seropédica-RJ. Utilizou o método Penman-Monteith FAO-56 para estimar a evapotranspiração de referência (ETo), e os valores de Kc foram determinados pela razão entre ETc, determinada por lisimetria de pesagem, e ETo. A ETc total do ciclo do repolho foi 411,55 mm e os valores de Kc para o repolho foram: 1,02 (I); 1,03 (II);1,05 (III) e 1,01 (IV), e se diferenciaram dos valores apresentados pela FAO, para cultivo convencional. A produtividade do repolho cultivado em sistema orgânico foi de 34,76 Mg ha-1, com uma eficiência do uso da água de 8,45 kg m-3. Palavras-chave: brassica oleracea, lisímetro de pesagem, cultivo sobre palhada de milho ARAÚJO, M. S. P; SOUSA, E. F.; CARVALHO, D. F; PEREIRA, V. R. EVAPOTRANSPIRATION AND CROP COEFFICIENTS OF CABBAGE IN AN ORGANIC SYSTEM 2 AbstraCt The study was carried out in order to estimate crop evapotranspiration (ETc) and crop coefficients (Kc) for the stages of “Fuyutoyo” cabbage, using weighing lysimeter. The field trial occurred in 2015, from July 17 to October 26, in areas cultivated with “Fuyutoyo” cabbage planted on a straw of corn, in the municipality of Seropédica, RJ, Brazil. The FAO-56 Penman-Monteith method was used to estimate reference evapotranspiration (ETo) and Kc values were determined by the ratio of ETc, determined by weighing lysimetry, and ETo. The total ETc of the cabbage cycle was 411.55 mm and Kc values obtained were: 1.02 (I); 1.03 (II); 1.05 (III) e 1.01 (IV), which were different from the values presented by FAO. The productivity of cabbage was 34.76 Mg ha-1, with water use efficiency of 8.45 kg m-3. Keywords: brassica oleracea, weighing lysimeter, cultivation on straw of corn

Surface Residues: Effects on Soil Moisture and Temperature1

et al. 2021

This study aimed to determine how crop residue placement and composition would affect soil water content and temperature during the dry season in the central region of Espírito Santo state, Brazil. A 19-week field study was conducted from April to August 2017. A 2 x 4 factorial study with four replications was implemented using a randomized complete block design. Factors were soil management [conventional tillage (CT) and no soil disturbance (ND)] and residue amendment [maize (Zea mays L.), sunn hemp (Crotalaria juncea L.), a maize-sunn hemp mixture, and a no amendment control]. Soil water content and temperature were measured weekly at predetermined soil depth intervals. Soil water content was higher in ND plots amended with surface residues than under all other treatments in the 0 to 0.05 m depth range. All residue amendments in this range were equally effective in conserving soil water. Surface residues reduced soil temperature by up to 8.4 °C relative to the control in ND plots. Incorporating residue amendments by CT cancelled all temperature-moderating benefits provided by surface residues. These results indicate that surface residues from cereals, legumes, or cereal/legume mixtures are equally effective in conserving soil water and moderating soil temperature during the dry season. Additional research is needed to determine how improved soil environmental conditions, generated by surface residues, would affect nutrient acquisition and crop performance.
