Mulching is a technique widely used in agriculture, recommended mainly for semi-arid regions, as it increases soil water retention, increases fertility through the supply of organic matter, improves its physical properties and mitigates the effects of erosion, covering the surface of the soil, totally or partially. In this way, the effects of mulch on the growth and productivity characteristics of forage palm clones (Opuntia stricta and Nopalea cochenilifera (L.) Salm-Dyck) and on the physical-hydric properties of the soil were evaluated. The experiment is being carried out under field conditions (rainfed) in the experimental area of the Forage Studies and Research Group (GEFOR), located at the Federal Rural University of Pernambuco, Serra Talhada Academic Unit (UFRPE – UAST), Serra Talhada, PE (7º58'20 ”South; 38º17'32” West and Altitude 499 m). The average annual rainfall is around 632 mm and the average monthly air temperature ranges between 23.6 and 27.7 ° C. According to Köppen, the local climate is BSwh ’. A randomized block design (DBC) in a 3 x 3 factorial scheme was used, with three forage palm clones resistant to carmine cochineal [Mexican Elephant Ear (Opuntia stricta), Sweet Miúda (Nopalea cochenillifera (L.) Salm-Dyck) and Doce Gigante (Nopalea cochenillifera (L.) Salm-Dyck)] and three cultivation systems [conventional system with bare soil (without mulch), partial mulch (0.30 m on each side of the row) and total soil mulch], with six replications. Structural parameters are being evaluated monthly in the cladode and in the plant of forage palm clones. To assess the soil's physical-hydric properties, soil density, sorbity, porosity and soil resistance to penetration were measured. The data were submitted to the normality test (Shapirowilk), homoscedasticity (Cochran), analysis of variance (5% F test), Tukey test (5%) for comparison of means and regression analysis. Analyzing the number of total forage palm cladodes (N. Cochenillifera and Opuntia stricta), there is superiority (P <0.05) of the clone Doce Miúda in relation to the clones Doce Gigante and Mexican Elephant Ear, regardless of the mulch in the soil . Therefore, it was possible to verify that the clones Orelha de Elfante Mexicana and Doce Gigante have an average primary cladode length and width greater than that of the clone Doce Miúda, which in turn demonstrates greater plant width and a greater total number of cladodes.
