Sowing depths of brachiaria in intercropping with corn in no tillage planting

Abstract: The forage production in crop-livestock integration is critical both for formation of straw for no tillage planting and food for livestock farm. The experiment was conducted in the autumn/winter of 2009 and 2010, in the city of Selvíria -state of Mato Grosso do Sul -MS, Brazil, at Experimental Station of FEIS/UNESP. The objective was to evaluate the optimal depth for deposition of seeds of two Brachiaria species intercropped with corn with emphasis on grain yield and straw. The experimental design was a random… Show more

“…Thus, there was a decrease in forage production, directly affecting the production of biomass in the no-tillage system. A similar result was obtained by Gazola et al (2013), who showed that shading by corn plants affected dry biomass production by Urochloa brizantha cv. Marandu and Urochloa ruziziensis due to the delayed emergence of the Urochloa plants.…”

“…Diversos autores também verificaram que a semeadura da B. ruziziensis simultaneamente à do milho não causou reduções na produtividade de grãos (Chioderoli et al, 2010;Garcia et al, 2012;Freitas et al, 2013;Gazola et al, 2013). Estes resultados se devem ao fato de B. ruziziensis apresentar crescimento inicial lento e, normalmente, não afetar o crescimento das plântulas de milho, que, contrariamente, possuem crescimento inicial rápido (Freitas et al, 2013).…”

“…However, the free-spacing promoted the incidence of weed plants such as Portulaca oleracea, Sida rhombifolia, and Richardia brasiliensis, which explain the reduction of 5% in grain yield from the shorter to wider spacing. The absence of grain reduction in the intercropping with AG and BR is explained by rapid ground cover, which avoided weed predominance [38]. It explains the challenge to maintain high yields in intercropping sorghum systems, especially in arid and semi-arid regions.…”

“…Probably there was high competition for nitrogen and phosphorus in the intercropping system, requiring the application of fertilizer to supply the demand of both plants. Therefore, fertilization is also an important practice to increase sorghum yield, mainly in the intercropping systems [30][31][32][33][34][35][36][37][38][39]. There was an increase of phosphorus in the soil associated with the application of 400 kg ha −1 reactive phosphate and 200 kg ha −1 of formulation 04-30-10 (nitrogen, phosphorus, and potassium).…”
