The objective of this work was to evaluate the effect of the use of plastic mulch and percolation barrier on the growth and distribution of pineapple roots. The BRS Imperial cultivar was cultivated using plastic as mulching material and a percolation barrier. The evaluated variables were: relative and absolute root growth rates, root length distribution, and root length density. The use of plastic mulch resulted in a greater accumulation of root dry matter, with or without the percolation barrier. Under drip irrigation, mulching promoted a greater root development. The highest root growth rate occurred from 360 to 450 days after planting. The amount of roots was from 64.1 to 66.7% on the stem, and from 34 to 36% distributed in the 0.10 and 0.20 m soil layer. Black plastic, as mulch or a percolation barrier, contributes to increase the root development of 'BRS Imperial' pineapple under drip irrigation.

Studies to improve the use of subsurface drippers in pasture formation are needed. Therefore, the objective of this study was to evaluate the germination and emergence of Sabia grass as a function of drippers installed at different depths. The study was conducted in pots in Viçosa, Minas Gerais State, Brazil. The experiment was conducted using a completely randomized design with four replicates. The experimental layout featured split plots over time, where the main plots consisted of three cultivation cycles and the subplots represented various dripper installation depths. The three sowing dates were 26 March, 12 April, and 29 April 2022. Drip tapes were installed at seven different depths: 0 (superficial), 5, 10, 15, 20, 25, and 30 cm. The results showed that the reduction in water potential, associated with increased temperature, resulted in lower performance of Sabia grass seeds. Seed germination and parameters related to germination speed were negatively impacted by the increase in dripper installation depth, with a 30–40% reduction in germination speed observed at depths greater than 15 cm. Drippers installed at 15–20 cm depth in clayey soil were ideal, providing a balance between reducing soil water evaporation and maintaining seedling emergence rates. Compared to surface installation, this depth improved seed performance by up to 25%, while enhancing operability and minimizing water loss. It is recommended to install drippers at a depth of 15–20 cm in subsurface drip irrigation systems in clayey soil areas to achieve benefits such as decreased soil water evaporation and improved operability compared to surface systems.
