| Among the problems faced by the melon crop in the state of Rio Grande do Norte, northeastern Brazil, the effect of water and soil salinity is considered one of the key factors to limit fruit production and quality. The aim of this work was to study the effects of using irrigation waters with different salinity levels on yield and quality of fruits of the yellow melon hybrid Mandacaru. A randomized complete block design was used with five treatments (irrigation water salt concentrations: 0.54, 1.48, 2.02, 3.03, 3.9 dS m-1) and four replications. The effects of these concentrations were evaluated through, number of marketable fruits per plant, marketable and total fruit yield, average marketable fruit mass, soluble solids content and pulp firmness.

| The application of cellulosic waste in forest plantations is an alternative to disposal, but more studies are necessary to confirm the safity of this disposal. The response of Pinus taeda L. to salinity in Humic Distrocryept was evaluated. In plantation, the seedlings were assessed for their height and stem diameter (SD), and at 120 days, were assessed the SD, height, dried root biomass (DRB), shoot (DBS) and total dried matter (TDM). The contents of P, K, Ca, Mg and Na were determinated, and, based on these levels it was estimated the quantity of these elements and calculated the efficiency use in leaves and roots and translocation to the shoot. Except the relationship between DSB/DRB, the other variables were significantly influenced by increased... |
