Abstract

The aim of this work to evaluate the effects of irrigation with waters of different salinity levels and proportions of manure bovine in the growth indexes of the castorbean. The experiment was carried out at University Federal Rural of Semi – Arid, Mossoró – RN, in a randomized blocks in a factorial scheme (4x4), with three replications a one plant/vase by plot. Four water salinity levels (S1=0,5; S2=2,0; S3=4,0 e S4=6,0, em dS m-1), adjusted through the addition of NaCl with four proportion of manure bovine in the substrates (E1=0; E2=3:1; E3=2:1; e E4=1:1). The variables appraised were: number of leaves, leaf area, stems diameter, height plant, phytomass of the aerial parts and phytomass of the root at 64 days after sowing. Every the variables was found to be affected by the studies factors, by saline levels and proportions of manure, without, any significant variation in the interaction (SxE). The results showed that the salinity of waters of irrigation from 4,0 dS m-1and positive in the proportions of manure bovine.
