Abstract
Studies regarding cover crops in areas of maize for silage are scarce in Brazil, especially those focused on the effect of these plants on maize nutrition.. This study aimed at evaluating the effect of different cover crops on the dry matter (DM) yield and on the accumulation of macronutrients in maize plants (cobs, leaves, stalks). The study was conducted at Fazenda Santo Antonio, in Matozinhos, MG, Brazil. A randomized blocks design was used, with four replications and nine treatments being eight species of cover crops Cultivated Radish (Raphanus sativus), Pearl Millet (Pennisetum americanum), Brachiaria ruzziziensis, B. decumbens, Crotalarea juncea, White Lupin (Lupinus albus), Black Oat (Avena strigosa) and Common Sunflower (Helianthus annuus) and one area of fallow land. The DM yield of maize plants was not affected by the cover crops. In general, macronutrients concentration in maize plants were not affected by treatments. On the other hand, the total amount of Ca and S changed in maize plants.. The amounts of macronutrients accumulated in maize cobs were not affected, except for the amounts of P and Ca in the leaves and stalks.
