| This research was conducted to study the direct fertilization combining 0 and 160 kg N ha-1 of cattle manure and green manure as branches of pigeon pea (Cajanus cajan L.) and their residual effects on two population densities of roquette (Eruca sativa Miller) crop, in Seropédica, Rio de Janeiro, Brazil. Yield, number of leaves plant-1, leaf area index, shoot fresh weight, stems dry matter, roots dry matter, leaves dry matter, total dry matter and plant height were measured. The experiment was a randomized block design set as a factorial 2 x 2 x 2, and three replications: 0 and 160 kg N ha-1 of cattle manure, 0 and 160 kg N ha-1 of branches of pigeon pea and 500,000 and 1,000,000 plants ha-1. The results indicate that the population density of 500,000... |

| In an intercropping lettuce-carrot system submitted to crescent dosages of organic compost (0; 12; 24; 48 Mg ha-1) were monitored carbon from soil microbial biomass (MBC), labile carbon in fumigated soil (LCF), in non-fumigated soil (LCNF), in autoclaved soil (LCA) and total organic carbon (TOC) at 0-10 cm of depth. Pasture and forest areas surrounding the experiment were used as reference. Five samples from soil were evaluated at 8 days before the beginning of the experiment, 0; 6; 60 and 114 days after manuring (dam). LCF was the attribute that presented the most consistent correlation with TOC that is usually utilized to detect changes in soil organic matter. Increasing dosages of organic compost caused the increase of MBC, LCF, LCNF, LCA and TOC. From... |
