Persistência de Stylosantes macrocephala/ capitata no estabelecimento de pastagem de Brachiaria decumbens cv. Basilisk em diferentes densidades de semeadura

Abstract

The objective of this study was to evaluate the effect of different plant densities of Brachiaria decumbens cv. Brasilisk in intercropping Stylosantes macrocephala/ capitata (Estilosantes Campo Grande), in order to better coexistence between grass and legume. The experiment was conducted Higher Education Center Rondonópolis located in the municipality of Rondonópolis. The experiment was established in a randomized design in blocks with five treatments and five repetitions treatment 1 = 3.5 kg, treatments 2 = 4.0 kg = 4.5 kg treatment 3 and treatment 4 = 5.0 kg of viable pure seed (SPV) of Brachiaria decumbens cv. Brasilisk. The seeding rate was set Estilozantes Campo Grande for all treatments at 3 kg / ha with 60% germination. The experiment was evaluated from December 2007 to May 2008 and a second evaluation in August and September 2008. For continuing review evaluations were performed at 7, 30, 50, 270 and 310 (DAE). As for dry mass analysis assessments were performed at 50, 100, 270 and 310 (DAE). The number of plants estilosantes/m2 were influenced by sowing density and times assessments. The largest number of plants estilosantes/m2 were observed to 241.85; 236.38; 256.33 and 214.81 of the associated 3.5 seeding rates; 4.0; 4.5 and 5. The highest number of plants estilosantes/m2 were observed with 4.80 sowing rates; 4.81; 4.61 and 4.59 times associated assessments 35; 100; 270 and 310 days after emergence. The dry matter yield were influenced only by seasons assessments. The Brachiaria decumbens associated with estilosantes had higher production capacity.
