The influence of cutting age on yield and nutrition rates of piatã grass (Brachiaria brizantha cv. BRS Piatã) and hybrid sorghum (Sorghum spp. cv. BRS 801) under an integrated crop-livestock system was evaluated. The trial was carried out at the Embrapa Beef Cattle (20°27¢ S; 54°37¢ W) in Campo  Grande, Mato Grosso do Sul State, Brazil, between April and October 2009. Experimental design consisted of randomized blocks with four replicates. Treatments were distributed across a split-plot design, which included three production systems (single piatã grass; single hybrid sorghum; mixed cultivation of sorghum and piatã grass). Half-plots consisted of three forage ages at harvest (with 70, 90 and 110 days after seeding). Variables included agronomical...

ABSTRACT Corn grain yield, nitrogen (N) fertilizer efficiency and distribution to corn alone and three forms of corn and palisadegrass (Urochloa spp.) intercropping implantation was investigated. A field experiment with 15N labeling fertilizer was performed in randomized block design. No form of palisadegrass intercropping implantation affected corn grain yield, total N accumulation and N use efficiency (NUE), which were 8.7 t ha-1, 205 kg ha-1 and 37% respectively. The palisadegrass produced on average 1.9 t of dry mass, absorbing a maximum of 6 kg ha-1 or 5.5% of N fertilizer during corn growing. Furthermore, the palisadegrass did not affect N fertilizer distribution in soil-plant system, in which 28.2% was recovered in the soil and 40.4% in the plants...

The aim of this work was to evaluate the effect of nitrogen fertilization and aerial part cuts on yield components, grain yield and quality of the grains for dual-purpose wheat cultivars. The experiment was carried out between May and November 2007 and the experimental design was randomized complete blocks with three replications. The main causes of variation were dual-purpose wheat cultivars (BRS Figueira, BRS Umbu, BRS Guatambu and BRS Tarumã), nitrogen doses (0, 45, 90, 135 and 180 kg ha-1) and cut systems. Each plot was subdivided by cut management (without cut, one cut and two cuts). Spike mass, number of spikelets per spike, number of grains per spikelet, grain yield and hectoliter weight were evaluated. Nitrogen fertilization did not affect the...

ABSTRACT: This study aimed to evaluate the relationship between economic indicators of soybean crops ( Glycine max L.) cultivated with Crop-Livestock Integration (CLI) or with grain production in winter, and the chemical, physical and biological attributes of the soil. It was selected ten agricultural sites in Santa Catarina to measure economic results and edaphic attributes, data was submitted to a Principal Components Analysis (PCA). Results indicated that soybean production in the summer and grain production in the winter yielded better economic results compared with summer soybean and CLI in winter. This reflects the higher productivity of the crops (9.1%) and the improved chemical, physical, and biological attributes of the soil (with the exception of...
