SOWING DENSITY, ESTABLISHMENT AND DRY MATTER PRODUCTION OF CEVADILHA VACARIANA. ABSTRACT: Bromus auleticus Trinius or cevadilha vacariana, is a perennial hibernal species native to the fields of southern Brazil, Uruguay and Argentina. The slow establishment is one of the problems pointed out in most works as the main difficulty for its use as perennial winter pasture. The present work aimed to study the effect of sowing density on the establishment and production of dry matter in B. auleticus, in the first and second year of pasture production. The applied treatments were sowing densities of 570 (T1), 840 (T2), 1,100 (T3), 1,350 (T4) and 1,700 (T5) viable seeds.m-2. There was no significant difference between treatments for the number of seedlings up to 35 days, nor for plant height up to 100 days after sowing and also for the number of days between sowing and first cut. Dry matter production was not affected by treatments either. In this experiment the sowing density had no influence on any of the evaluated characteristics. It was also not possible to establish an association between number of plants and dry matter production in the first cut in the year of establishment.

Elucidating the mineralization of organic composts makes it possible to understand the release of nutrients to plants. The objective of this study was to evaluate the mineralization of nitrogen (N) and carbon (C) from organic compost from residues of the production and slaughter of small ruminants, applied on a Neossolo Flúvico (Fluvents). The compost consists of remains of grass (forage), manure and slaughter residues such as blood, viscera and the carcass of goats and sheep. Under laboratory conditions, two experiments were conducted in a completely randomized design, considering the doses of organic compost at the following levels: zero; 3.75, 7.5, 15 and 30 Mg ha-1. For the N and C mineralization tests, 11 and 32 collection times (sampling periods) were evaluated, respectively. Inorganic N content (ammonium and nitrate) was measured in the N mineralization test, and CO2-C concentration was quantified in the C mineralization test. The largest increments between the applied doses of organic compost from residues of the production and slaughter of small ruminants were 70% and 69% for potentially mineralizable N and C, with amounts of 7.5 and 30 Mg ha-1 at doses of 3.75 and 7.5 Mg ha-1, respectively. Organic C and N from residues of the production and slaughter of small ruminants are rapidly mineralized in the soil (up to 45 days) due to their low C/N ratio. |
