| ABSTRACT The objective of this study was to evaluate the growth of forest species under conditions of salinity and water deficit. The experimental design was completely randomized in a triple factorial scheme with four forest species (Neem - Azadirachta indica A. Juss, ‘Aroeira’ - Myracrodruon urundeuva Fr Allemão, ‘Ipê’ - Tabebuia impetiginosa (Mart. ex. DC.) Standl and ‘Sabiá’ - Mimosa caesalpiniifoliaBenth), two salinity levels (1.2 and 8.6 dS m-1) and two water regimes (with and without water restriction). Plant height, stem diameter, number of leaves, shoot dry matter, root dry matter and total dry matter were measured. For all the studied variables, there was statistical significance for the factors species (A) and salinity (B), individually.... |

| Objetivou-se avaliar a interação entre salinidade e o uso de bioestimulante sobre o crescimento inicial de pinhão-manso. O experimento foi desenvolvido nos meses de agosto a outubro de 2012, na Universidade Federal Rural do Semi-Árido, em Mossoró, RN, utilizando o delineamento inteiramente casualizado, em esquema fatorial 2 x 4. Os tratamentos foram obtidos da combinação de dois níveis de sais da água de irrigação (0,5 e 5,0 dS m-1) e quatro intervalos de aplicação de bioestimulante (I1 – Ausência; I2 - 7 dias; I3 - 14 dias; I4 – 21 dias). Utilizou-se o fitorregulador comercial Stimulate® 10X, na concentração padrão de 18 mL L-1 de solução e se avaliaram as seguintes variáveis: altura, diâmetro do caule, comprimento da raiz principal, número de folhas,... |

| ABSTRACT The objective of the study was to evaluate the effect of different managements of fertigation and NK doses on the production of bell pepper fruit in a protected environment. The experimental design was randomized blocks in 3 x 5 factorial. The treatments were formed by the combination of three managements of fertigation (M1 - Based on the rate of absorption; M2 - Monitoring the electrical conductivity of the soil solution; M3 - Monitoring concentrations of N and K ions in the soil solution), with five doses of NK (0, 50, 100, 150 and 200% of the recommended dose) and four replicates. Six samples were collected and the following variables were evaluated: number, length and diameter of fruit, pulp thickness and fruit production. Except for diameter,... |

| ABSTRACT The split-root technique was used as a strategy to reduce saline stress on pepper. A completely randomized design with six treatments and four replicates was used. The treatments consisted of six saline water application strategies (T1 - salinized nutrient solution (S1 = 1.4 dS m-1) during the whole cycle; T2 - salinized nutrient solution (S2 = 4.5 dS m-1) throughout the cycle, T3 - S1 and S2 throughout the cycle, using two emitters and without splitting the root system, T4 - S1 and S2, using two emitters and splitting the root system by a plastic film, T5 - S1 and S2, using two emitters and splitting the root system, alternating the solutions every 15 days, T6 - S1 and S2, using two emitters and without splitting the root system, alternating the... |
