Abstract

Cashew rootstock production in the semi-arid region of northeastern Brazil, where the waters available for irrigation are generally saline, is dependent on cashew clones adapted to local edaphoclimatic conditions. Thus, the objective of this research was to evaluate the effects of irrigation with increasing salinity waters under the phytomass allocation and growth of different cashew clones. The experiment was carried out in a greenhouse of CCTA / UFCG, Campus Pombal - PB, using a randomized block design in a 5 x 4 factorial scheme, whose treatments consisted of different levels of electrical conductivity of irrigation water - CEa (0.3, 1.0, 1.7, 2.4 and 3.1 dS m-1) associated with different cashew clones (CCP 76, Embrapa 51, Faga 11 and Creole), with three replications and two plants. by parcel. Irrigation water salinity up to 1.30 dS m-1 provides acceptable losses of 10% in the phytomass allocation and growth of cashew clones. Dry leaf phytomass allocation and leaf air ratio were increased by salt addition in irrigation water. The Crioulo cashew rootstock has the highest total dry phytomass accumulation at 65 days after sowing.
