The objective was to evaluate the effect of the planting density of cactus pear cv. Mexican elephant ear under soil physical and chemical properties. Four planting densities were tested: 30,000, 45,000, 60,000 and 75,000 plants distributed in a randomised block design with four replications. After 360 days of cultivation, soil samples were taken in different profiles (0.0–0.10, 0.10–0.20, 0.20–0.30 and 0.30–0.40 m). The physical–chemical analysis included soil density, particle density, porosity, pH, electrical conductivity (EC), phosphorus (P), potassium (K+), sodium (Na+), calcium (Ca2+), magnesium (Mg2+), copper (Cu2+), iron (Fe2+), manganese (Mn2+), zinc (Zn2+), exchangeable acidity (H+Al), sums of bases (SB), cation exchange capacity and base saturation (V). The results were tested using analysis of variance, regression at 5% probability and principal component analysis (PCA). Physical properties along the soil profile and soil chemical properties in the 0–0.10 m profile were not altered (P > 0.05) by the density. There was a decreasing linear effect (P < 0.05) of density on the P content in the 0.10–0.20, 0.20–0.30 and 0.30–0.40 m profiles. Mg, Zn and V in the 0.10–0.20 m profile and Ca in the 0.30–0.40 m profile decreased linearly (P < 0.05) as a function of density. There was an increasing linear effect (P < 0.05) of planting density on Fe in the 0.20–0.30 m profile. The PCA showed that the factor loadings of the chemical properties of the soil in the different profiles were greater than 75% in the first two components. Except for the 0–0.10 m profile, with 55.77%. Minerals that contributed most to PC were Ca, K, P, Mg and Mn. In this sense, increasing the planting density of cactus pear without the use of fertiliser demands more from the soil, recommending lower densities between 30,000 and 45,000 plants ha−1.

Brachiaria humidicola is a perennial and stoloniferous forage grass, with excellent adaptation to infertile soils and waterlogging. Producers in northern Brazil have become interested in this species, especially after the degradation of large areas of lowly permeable soils sown with B. brizantha cv. Marandu, which is highly intoler-ant of soil waterlogging (Andrade and Valentim 2006). However, since only 3 cultivars of B. humidicola are registered in Brazil (Mapa 2013), there is a need to de-velop new cultivars adapted to the range of environ-mental conditions experienced. Recently, Embrapa Beef Cattle obtained intraspecific hybrids of B. humidicola that need to be evaluated agronomically, aiming at sub-sequent grazing trials and future releases. The objective of this study was to evaluate and select apomictic and sexual hybrids of B. humidicola under the environmental conditions of the state of Acre, in western Brazilian Amazon. |
