Comportamento morfofisiológico da mamoneira BRS Energia submetida à irrigação com água salina

Abstract: RESUMOUm experimento foi conduzido na estação experimental de Irrigação e Drenagem do Instituto Federal Baiano, para avaliar o crescimento da mamoneira BRS Energia, em função da salinidade da água de irrigação, em sistema de lisimetria. Os tratamentos foram constituídos dos níveis de salinidade da água de 0,12; 0,8; 1,6; 2,4; 3,2; 4,0 e 4,8 dS m -1 , dispostos em delineamento inteiramente casualizado, com três repetições e quatro plantas por tratamento. Quinzenalmente foram avaliados, dos 20 até os 80 dias apó… Show more

“…Ayers and Westcot (1999) explained that as in ECw, at 30, 60, 90, 120, and 150 DAS, respectively. These results are consistent with those reported by Santos et al (2013), who concluded that stem diameter of the 'BRS Energia' castor bean revealed a moderately soil salinity increases, water availability to crops decreases, and under these conditions plants require more energy to absorb water from the soil, which causes reduced growth. This was observed by Lima et al (2007), who studied the influence of saline water on soil physico-chemical characteristics and on the development of the 'BRS Energia' castor bean cultivated in pots.…”

“…Previous studies (CAMPOS et al, 2009;SOARES et al, 2012;NOBRE et al, 2013;SANTOS et al, 2013;LIMA et al, 2014aLIMA et al, , 2014b have shown the effects of irrigation water with high salinity on the cultivation of the castor bean cultivar, 'BRS Energia'. However, they are limited to water with different salinity levels; therefore, further studies are necessary, especially on the castor bean 'BRS Gabriela' cultivar, on the effect of nitrogen (N) levels and saline water, to mitigate the negative effects caused by saline stress.…”

“…A redução da AP é consequência do efeito osmótico dos sais dissolvidos que reduzem o potencial osmótico da solução do solo e inibem a condução da água às células, caracterizando o estresse hídrico além da possibilidade de ocorrência de toxicidade iônica, desequilíbrio nutricional, ou ambos, em função da acumulação excessiva de determinados íons nos tecidos vegetais (Flowers, 2004). Corroborando com os resultados obtidos no presente estudo, Santos et al (2013) constataram, avaliando o crescimento da mamoneira BRS Energia em função da salinidade da água de irrigação (CEa: 0,12 a 4,8 dS m -1 ) em condições de campo, aos 80 DAS, redução na AP de 6,27% por incremento unitário da CEa.…”

“…Thus, many authors have studied the effects of irrigation water with different salinity levels on the cultivation of castor bean (Campos et al, 2009;Soares et al, 2012;Alves et al, 2012;Nobre et al, 2013;Santos et al, 2013;Lima et al, 2014a); however, information on the effect of water with different cationic nature is still scarce.…”
