Development of young cashew “clone brs 275” under irrigation with different saline levels

Most cashew orchards in Brazil is located in semi-arid tropics, where water is scarce and has salinity problems. Based on this fact, this study aimed to evaluate the effect of salinity on early development of seedlings of cashew BRS 275. The experiment was conducted in a greenhouse at Embrapa Fortal...

Description
Summary:Most cashew orchards in Brazil is located in semi-arid tropics, where water is scarce and has salinity problems. Based on this fact, this study aimed to evaluate the effect of salinity on early development of seedlings of cashew BRS 275. The experiment was conducted in a greenhouse at Embrapa Fortaleza - CE, Brazil. Seeds of BRS 275 were sown in containers containing vermiculite. The treatments were saline solutions with different electrical conductivity(ECw) 3, 6, 9 and 12 dS m-1 , being the distilled water used as control (0 dS m-1 ). The experiment was a completely randomized design with four replications of five seedlings per plot. Evaluated it seedling height (AP) diameter of the seedling (DP), number of leaves (NF), leaf area (AF), dry matter of leaf (MSF), dry matter of stem (MSC), dry matter of root (MSR) and the substrate conductivity (CEs), obtained 15 days after emergence of seedling. The irrigation with saline water showed a linear effect for all variables of plantets, except for DP that showed no significance and the MSC had a quadratic effect. The increasing salt concentration reduced the early development of seedlings of cashew, clone BRS 275.
