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...

Investigou-se o efeito das coberturas de inverno centeio, aveia, azevém, ervilhaca e nabo forrageiro (e suas associações), em sistema de plantio direto, sobre a cobertura do solo e a produção de biomassa das coberturas de inverno, sobre a biomassa de plantas espontâneas de verão, no período crítico de competição, e sobre a produtividade do feijão, cv Guará. O experimento foi instalado em delineamento experimental constituído por blocos ao acaso com quatro repetições. Observaram-se as maiores percentagens de cobertura do solo no inverno, com os tratamentos centeio + ervilhaca, centeio + ervilhaca + nabo forrageiro e aveia + ervilhaca; a produção de biomassa de cobertura foi maior com centeio + ervilhaca + nabo forrageiro. O efeito de supressão observado foi...

Autores: Bertolaccini,Isabel; Núñez-Pérez,Etelvina; Tizado,Emilio Jorge.
The study was done during the spring, summer and fall of 1998 and 1999. Samples were taken at random from legume crops and spontaneous plants adjacent to them in the province of León (Spain). Observations were made on the following crops: Medicago sativa, Phaseolus vulgaris, Pisum sativum, Cicer arietinum, Trifolium repens, Vicia fava, Trifolium pratense, Vicia ervilia, Lathyrus cicera, Lathyrus sativus, Trigonella foenum-graecum, Lupinus albus, Lupinus angustifolius and Lens esculenta. Twenty three families of spontaneous plants were observed. The aphid species and their population densities on the spontaneous plants and crop plants were recorded, as was the presence of members of the families Coccinellidae, Syrphidae and Chrysopidae. The plant families...
