“…It can be seen that controlling SWP of -50 kPa will greatly influence fruit quality, while controlling SWP within a relative deficit range (for example -30 to -40 kPa) maybe benefit crop quality. Findings of Ma et al (2006) [22] is similar to our conclusion, who found that the deficit irrigation treatments enhance soluble solid matter in jujube fruits and improve the fruit quality. …”

“…Bandeira et al (2013) also obtained highest marketable yield of onion bulbs applying water depth corresponding to 100% ETc, compared with 75% ETc, performing irrigation management with Class A pan and without using mulch. Similar effect of different irrigation depths on onion bulb yield have also been observed by Olalla et al (2004), Enciso et al (2009), Ramalan et al (2010) and Igbadun et al (2012). Kumar et al (2007) demonstrated that a greater water comfort to the onion crop is obtained when the soil is maintained close to field capacity (100% ETc), promoting …”

A B S T R A C TThe objectives of this study were to obtain the onion crop coefficients and evaluate the influence of different irrigation depths (0, 22, 45, 75 and 100% of crop evapotranspiration) on marketable yield and quality of onion bulbs cultivated with and without mulch of elephant grass. The experiment was carried out in Seropédica, RJ, Brazil, from May to September 2012, in a Red Yellow Argisol. The experimental design was in randomized blocks in split plots, with 10 treatments and seven replicates. Irrigation management was performed through soil water balance using the Time Domain Reflectometry technique, with probes installed horizontally at 7.5 and 22.5 cm depths. The use of mulch allowed the application of smaller irrigation depths, leading to lower crop coefficient (18% in stage II and 3% in stage III) in comparison to the crop without mulch. Irrigation depths associated with the use of mulch influenced the evaluated production variables, proving to be an alternative to increase marketable yield and quality of onion bulbs, with lower irrigation depth.Produtividade comercial da cebola sob diferentes lâminas de irrigação, com e sem cobertura do solo R E S U M O Objetivou-se neste estudo obter os coeficientes de cultivo para a cultura da cebola e avaliar a influência de diferentes lâminas de irrigação (0, 22, 45, 75 e 100% da evapotranspiração da cultura) na produtividade comercial e na qualidade de bulbos de cebola, cultivada com e sem cobertura vegetal morta de capim-elefante no solo. O experimento foi realizado em Seropédica, RJ, Brasil, entre maio e setembro de 2012, em um Argissolo VermelhoAmarelo. O delineamento experimental adotado foi em blocos casualizados em parcelas subdivididas, com10 tratamentos e sete repetições. O manejo da irrigação foi realizado por meio do balanço de água no solo utilizando a técnica da Reflectometria no Domínio do Tempo, a partir de sondas instaladas horizontalmente a 7,5 e 22,5 cm de profundidade. A utilização da cobertura morta permitiu a aplicação de menores lâminas de irrigação, proporcionando coeficientes de cultivo inferiores (18% no estágio II e 3% no estágio III) ao cultivo sem cobertura do solo. A lâmina de irrigação associada ao uso da cobertura vegetal morta no solo influenciou as variáveis de produção avaliadas, demonstrando ser uma alternativa para elevar a produtividade comercial e a qualidade de bulbos de cebola com menor lâmina de irrigação.

“…Kumar et al (2007) attributed this response pattern to the variation in soil moisture because higher water levels promote better water comfort to the plants. Saunders (1998), Martin de Santa Olalla et al (2004) and Enciso, Weidenfeld, Jifon, and Nelson (2009) also observed this response pattern in their studies with different irrigation depths in onion cultivation.…”
