| Abstract Soil management is a practice that influences the development of fruit trees. In this sense, the objective of this study was to evaluate the effect of different soil cover/mulching types on weed control and on the early development of pear trees Hosui cultvar. The experiment was conducted in two consecutive cycles: 2015/2016 and 2016/2017. Treatments consisted of the following soil covers in pear tree planting rows: natural cover, ryegrass straw intercropped with millet, pine sawdust, shading cover (70%), rice husk, Curauá fiber and weeding. Soil infestation by weeds was evaluated in the spring-summer period for two years, as well as the vegetative pear tree development (plant height and diameter and SPAD chlorophyll index). Managements using... |

| The objective of the experiment was to identify the morphological alterations in corn genotypes in response to aluminum toxicity in the soil. A complete randomized block design with five replications was used. The a factorial scheme was composed of two corn genotypes (C525M - tolerant, and HS701B - sensitive) and two neutralization levels (0% and 100% of aluminum saturation). The evaluations were performed at six leaf and 10-11 leaf growth stages, emergence of the "stigma-style", and the physiological maturity. The presence of toxic aluminum didnt significantly reduce diameter and height of stem, leaf area, dry matter of aerial parts, total dry matter and yield. Stem diameter, leaf area, dry matter of root, dry matter of aerial parts, total dry matter and... |
