- Abstract
The use of saline water in agriculture may be a good alternative in several regions worldwide. However, the development of techniques is required to make feasible the use of this water in agriculture. Current paper evaluates the effect of salinity in irrigation water under physiological responses and phytomass production of early CCP 06 dwarf cashew rootstocks associated with increasing doses of organic matter in an assay undertaken in protected environmental conditions of the Centro de Ciências e Tecnologia Agroalimentar da Universidade Federal de Campina Grande (CCTA/UFCG), Campus Pombal (PB). Experimental design was totally randomized, with a 5 x 4 factor scheme, with three replications and two plants per split. Treatments were composed of five levels of water electrical conductivity (0.3; 1.0; 1.7; 2.4; 3.1 dS m-1) and four doses of organic matter (2.5; 3.5; 4.5; 5.5% in a soil volume base). Irrigation water salinity up to 0.90 dS m-1 provides acceptable losses of 10% in transpiration, stomatal conductance and liquid photosynthesis of CCP 06 cashew rootstocks. The 2.5% MO dose provided a greater production in the dry matter of the stalk when compared to the cashew rootstock during the assay. Increase in irrigation water salinity causes deleterious effects on the dry mass of leaf, stalk and root in the two periods under analysis.
