| Two experiments were conducted to evaluate the effect of salinity on early physic nut plant development. In the first trial, physic nut seeds were exposed to seven levels of salinity (0, 2, 4, 6, 8, 10 and 12dS m-1) with eight repetitions, using a substrate of paper soaked with solutions of CaCl2 and KCl. The treatments were evaluated based on the initial germination, total percentage of germination, and time necessary to germination of 50% of the seeds. Increased salinity reduced the first germination count and delayed the time to 50% germination. From 10dS m-1, there was a reduction in germination percentage. The second trial evaluated the effect of salinity on the growth of physic nut seeds. This trial, carried out inside a greenhouse, with a completely... |

| The experiment was performed in the experimental area of the Engineering Department Federal University of Lavras, Minas Gerais State, Brazil. It aimed at identifying the adequate irrigation management of the greenhouse-cultivated Japanese cucumber (Cucumis sativus L.). complete randomized design, with four levels of soil water potential (15; 30; 60 e 120 kPa) at two phenological phases (vegetative and reproductive), and 5 replications. Overall, the results showed decrease of yield according to increase of soil water potentials. During the reproductive stage, Japanese cucumber plants were more sensitive to water deficit, resulting in further decrease in yield compared to applied water deficit during the vegetative stage of the culture. |

| ABSTRACT In view of the imminent need for efficient water use and the search for adequate management techniques to reduce the effect of salinity on plants, a study was conducted to evaluate the effect of continuous and pulses drip irrigation with saline water on green bean yield and water use efficiency. The experiment was conducted in a greenhouse, in a completely randomized design, with treatments distributed in a 2 x 5 factorial arrangement. The first factor was type of drip irrigation, i.e., continuous or pulse, while the second factor was the levels of water salinity (electrical conductivity of 0.3, 1.5, 2.5, 3.5 and 4.5 dS m-1), with five replicates, and two plants per replicate, totaling 50 experimental units. The following variables were analysed:... |
