- Abstract
The objective of this work was to evaluate the effects of salinity of irrigation water on the initial growth of the plants of noni, cultivated in two environments, in the absence or presence of organic matter. The statistical design was adopted in random blocks in a split plot scheme, with 5 repetitions. The plots were set up by cultivation environments (open sky and screenhouse), the subplots by salinity levels of irrigation water (CEw: 0.3; 1.5; 3.0; 4.5 and 6.0 dS m-1) and the subsubplots represented by the absence and presence of organic matter. The electrical conductivity of the saturation extract (CEes) was measured at 110 days after application of the treatments (DAT). The plant growth parameters were evaluated at 30, 60, 90 and 110 DAT. The salinity of irrigation water caused linear increment in CEes, independent of the cultivation environment, being the values always bigger in presence of organic matter. Noni plants grown under screen conditions were more tolerant to salinity than those grown in the open. The open air environment provided better quality of seedlings, but the organic matter did not attenuate the effects of salinity on initial growth and quality of noni seedlings in the evaluated environments.
