“…Regarding the cover crops, rye was not effective against I. grandifolia, but the rye cover crop reduced the biomass of all other weed species, which is consistent with the results obtained in field conditions (Bittencourt et al 2009;Kieling et al 2009;Bonjorno et al 2010;Altieri et al 2011). Fodder radish negatively influenced the germination of I. grandifolia and also reduced the biomass of E. heterophylla and B. plantaginea.…”

“…These yields were less than half that of the biomass produced by plants in the control treatment (Table 2). These data confirm the field studies that underlined the effect of the Poaceae species biomass used as winter cover crops to reduce the dry weight of summer weeds in annual crops fields under no-tillage systems in the region from which the seeds and plant mulch were collected (Bittencourt et al 2009;Altieri et al 2011). Both treatments; rye and the combination of the tree cover crops, reduced the shoots biomass production of I. grandifolia and B. pilosa.…”

A greenhouse assay was carried out to evaluate the effect of winter cover crop residues on spontaneous plants that commonly occur on summer annual fields in Southern Brazil. Dry shoot residues of rye (Secale cereale), vetch (Vicia villosa), fodder radish (Raphanus sativus), and a mix of the three species, were applied over pots that had been seeded with alexandergrass (Brachiaria plantaginea), hairy beggarticks (Bidens pilosa), wild poinsettia (Euphorbia heterophylla), and morning glory (Ipomoea grandifolia) at four dif-

This paper aimed to evaluate the productivity of corn crop for silage, beans and straw production in different crop rotation systems with spring/summer and fall/winter green manures cultivated under agroecological production management. The experiment was implemented in a rural property managed in an agroecological system since 2009, in the 2017/18 and 2018 crops. The experimental design used was in randomized blocks, with five repetitions. The treatments consisted of four different crop rotation systems: monocrop corn/monocrop corn/fallow/beans; corn + cowpea/monocrop corn/oats/beans; corn + crotalaria/monocrop corn/forage radish/beans and corn + jack bean/monocrop corn/vetch/beans. After the 2018 second crop of corn was removed, the winter/spring green manures were sown: forage radish, vetch, and oats. This was followed in September by the bean crop. The dry matter yields of corn for silage in each growing season and of the bean were evaluated, as well as the total productivity of the systems. The straw yield was also evaluated. The crop rotation systems that included green manures presented the highest total productivity. The intercropping with pork bean favored the corn productivity in the harvest and the crotalaria stover favored the productivity in the off-season. The corn + cowpea/jack bean/beans monocrop and corn + crotalaria/jack bean/forage radish/beans systems favored the productivity of beans. The mode corn monocrop/corn monocrop/fallow did not prioritize the accumulation of straw on the soil.

ABSTRACT. The aim of this study was to evaluate dry matter production of cover crops (oats, turnip, vetch and spontaneous plants) and their effect on bean yield and physical properties of soil after succession. The experimental design was randomized blocks, and treatments consisted of four species of cover crops: oat, turnip, vetch and spontaneous plants, with five replications. The cover crops were sown in winter; when in full bloom, they were cut close to the ground and left underground. The bean crop was then sown underneath this residue in a no-till system. The results show that the cover crop that yielded the most dry matter was oats with 4,900 kg ha ). Cover crops had no effect on macroporosity and total porosity of soil depth from 0.05 to 0.20 m. There was a statistical difference in soil bulk density in the layer from 0.05 to 0.10 m, and bulk density (1.18 kg dm -3 ) was obtained in the treatment where the bean crop was cultivated after spontaneous plants.Keywords: green manuring, crop rotation, oat, oilseed radish, vetch, spontaneous plants.Efeito de plantas de cobertura sobre a produtividade do feijão e propriedades físicas do solo em sistema de plantio direto RESUMO. O objetivo do trabalho foi avaliar a produção de massa seca de plantas de cobertura de aveia preta, nabo forrageiro, ervilhaca comum e plantas espontâneas e seu efeito na produtividade do feijão e nas propriedades físicas do solo após a sucessão. O delineamento experimental utilizado foi de bloco ao acaso; os tratamentos foram constituídos de quatro espécies de plantas de cobertura: aveia preta, nabo forrageiro, ervilhaca comum e plantas espontâneas (pousio), com cinco repetições. As plantas de cobertura foram semeadas no inverno e quando estavam em pleno florescimento foram cortadas rente ao solo e deixadas sob o solo. Sob esta palhada a cultura do feijão foi semeada, no sistema de plantio direto. Os resultados demonstram que a planta de cobertura que proporcionou maior produção de massa seca foi à aveia preta com 4.900 kg ha -1 , sendo que não diferiu estatisticamente do nabo forrageiro com produção de 4.000 kg ha -1 . A vegetação espontânea produziu a menor quantidade de massa seca, e diferiu dos demais tratamentos. A ervilhaca apresentou o seu desenvolvimento prejudicado nas condições edafoclimáticas da região de Marechal Cândido Rondon, Estado do Paraná. A produção de massa seca da ervilhaca foi de 2.375 kg ha , obtida no tratamento em que a cultura do feijão foi cultivada em sucessão as plantas espontâneas.Palavras-chave: adubação verde, rotação de culturas, aveia preta, nabo forrageiro, ervilhaca, plantas espontâneas.
