“…Probably, the reduction in SDM under water excess conditions occurred due to the reduction of oxygenation in the soil, according to the observations of Almeida et al (2018). With regard to ground cover, Chieppe Júnior et al (2007) reinforce that there is influence of soil cover on crop growth and yield, where the increase in soil moisture with excessive water depths and the reduction in evaporation due to vegetation cover can negatively influence the yield of plants.…”

In regions with limited water resources, efficient use of water has become increasingly essential for agricultural production. The objective of the present study was to evaluate the use of the carnauba palm bagana (leaf fibers) as an option of ground cover to reduce the use of water in irrigated radish. The study was conducted from July to October 2018 in two crop cycles in Pentecoste-CE, Brazil. The experiment was carried out in randomized blocks with split plots and four replicates, whose primary treatments consisted of five irrigation depths (50%; 75%; 100%; 125% and 150% of the evapotranspiration crop) and secondary treatments consisted of five different levels of ground cover using carnauba bagana (0%; 25%; 50%; 75% and 100% of 16 t ha-1), in a 5 x 5 interaction, totaling 100 experimental plots. The following variables were evaluated: fresh mass of shoots and tuber, plant height, number of leaves, tuber diameter and gas exchange. For tuber fresh mass in the first crop cycle, a first order model was obtained with the response surface, with linear increase of the factors irrigation depths (0.064 g plant-1) and ground cover (0.065 g plant-1), with the highest value (40.44 g plant-1) observed for the level of 150% ETcloc and 100% bagana. Application of 16 t ha-1 of carnauba bagana can be considered recommended, within the limits studied, for use in the radish crop.

“…The radish crop (Raphanus sativus L.) is quite relevant in some regions of Brazil, including the Northeast region (ALMEIDA et al, 2018), being used in salads and in the manufacture of preserves. However, the sensitivity of this vegetable to water deficit may be a determining factor for the reduction in yield.…”

Water scarcity and the use of brackish water are the main challenges for agricultural development. In view of this, the present study proposes to examine physiological responses of the broadleaf-cress crop in an NFT hydroponics system according to the use of brackish water and nutrient solution circulation times. The treatments were distributed in a randomized block design with five water salinity levels (ECw: 0.6, 1.6, 2.6, 3.6 and 4.6 dS m-1) and two nutrient solution circulation times (T1 = 10 min and T2 = 15 min), totaling 10 treatments with four replicates, which resulted in 40 experimental plots. The following variables were analyzed: net photosynthetic rate, stomatal conductance, transpiration, leaf proline content, shoot moisture content, stem diameter and root length. The maximum observed photosynthetic rates were 20.9 mmol m-2 s-1 (T1) and 20.0 mmol m-2 s-1 (T2). Maximum stomatal conductance was 0.44 mol m-2 s-1, which decreased by 63.4% at the highest salinity level. The increasing ECw levels in both growing cycles evaluated reduced gas exchanges, stem diameter and root length. The nutrient solution circulation time of 15 min provided the most satisfactory results for the analyzed variables.
