Use of a conditioning unit at the haymaking of Tifton 85 overseeded with Avena sativa or Lolium multiflorum

Abstract: -White oat and ryegrass were overseeded on Tifton 85 pastures for evaluation of dry matter yield (DMY), leaf:stem ratio (L:S), dehydration curves and nutritional value of forages. Dry matter intake and L:S ratio were analyzed using a completely randomized blocks design with five forage growth conditions (single Tifton 85 and intercropped with white oat or ryegrass, and white oat or ryegrass intercropped with Tifton 85), whereas for drying curves, ten dehydration times were tested (0, 4, 8, 24, 28, 32, 48, 52, … Show more

“…Em se tratando dos fenos, os valores obtidos para os fenos de Tifton 85, Aveia Preta, Azevém e Alfafa são coerentes com os observados em outros estudos (NERES et al, 2010;CASTAGNARA et al, 2012b).…”

“…Sem irrigação, em trabalhos de Cynodon com aveia as taxas de acúmulo variam 20 a 66 kg MS ha -1 d -1 (Rocha et al, 2007;Olivo et al, 2010;Neres et al, 2011;Castagnara et al, 2012); com irrigação, Moreira et al (2006a) , respectivamente. Neste ciclo os valores médios de tensão de água no solo ficaram próximos, iguais a 5,6 kPa irrigado e 7,4 kPa não irrigado; no segundo ciclo ocorreram as menores temperaturas média (16,9 ºC) e mínima (11,7 ºC), com precipitação inferior à do primeiro ciclo (67 mm), com tensões de água no solo de 7,5 e 10,6 kPa, com e sem irrigação, respectivamente (Tabela 3).…”

“…A FDA da pastagem com ou sem irrigação foi semelhante, com média 32,4%, coerente com os valores encontrados em literatura variando de 30 a 40% para capins do gênero Cynodon com ou sem sobressemeadura de forrageiras de inverno (Moreira et al, 2006b;Neres et al, 2011;Castagnara et al, 2012;Silva et al, 2012); dentre esses, apenas Neres et al (2011) observaram que o valor da FDA em capim Tifton 85 sobressemeado com aveia diminuiu significativamente de 40 para 36,2%.…”

“…In oversowing systems the black oat has been the most used due to its tolerance to rust; however research conducted with white oat has shown better nutritional value of this species (NERES et al, 2011;CASTAGNARA et al, 2012) coupled with the market launch of cultivars more resistant to rust and longer cycle since most of white oat cultivars available in the market are intended for grain production. Oliveira (2007) points out that few studies in the literature evaluates this association of summer perennial species with those annual from winter in terms of forage production, botanical composition, interaction between cultures and forage quality.…”
