“…According to the literature, a post-cutting height of 0.3 m was left as residue for Guinea grass (Simonetti et al, 2016) and of 0.1 m for Bermuda grass (Sanches et al, 2017). In intercropping systems, cutting cycles varied depending on the winter forage growth.…”

One of the limitations to producing irrigated forages is setting suitable biometric parameters to establish the entrance of animals to grazing areas. Such parameters can be measured or even estimated. Estimates are advantageous for being practical and able to be used for grazing optimization. This study aimed to evaluate the correlation among growing degree-days (GDD), canopy height (CH), leaf area index (LAI), and number of cycle days (NCD) of Guinea grass (Panicum maximum cv. Mombaça) and Bermuda grass (Cynodon spp. Tifton 85) single cropped for one year and overseeded with black oat and ryegrass in the autumn-winter season. The study was carried out from February 2016 to February 2017, and forage crops were sprinkle irrigated. LAI and CH were measured twice a week, at intervals of 3 and 4 days. These parameters were correlated to GDD accumulation at each cutting cycle (CC). All the correlations showed high coefficients in linear fits. For spring-summer cycles, Guinea grass in exclusive cultivation showed the highest averages for CH and LAI, being 102.3 cm and 5.93, respectively. For autumnwinter cycles, when this grass was overseeded, it showed an LAI value similar to that when single cropped, which was of about 5.6. Yet single Bermuda grass presented lower values of LAI (one unit lower) and CH (16.4 cm lower) in the autumn-winter season when compared to that overseeded. The spring-summer cycles of Guinea grass had a duration of 24 days, after which no increase in leaf production was registered.

“…Para a variável matéria seca as populações milho com mucuna irrigado com solução mineral e a população que continha 25% milho irrigado com solução orgânica obteve maiores médias. Simonetti et al, (2016) constataram que o uso de biofertilizante nas pastagens apresenta resultados significativos na produtividade e no teor de proteína. Para a avaliação no segundo ciclo, PB as populações 75% milho e 50% milho irrigadas com solução mineral e 75% milho irrigado com solução orgânica obtiveram maiores médias para essa variável.…”

A forragem hidropônica é uma tecnologia de produção de período curto, produção contínua, cultivo em todas as estações do ano, produtividade elevada, baixo consumo de água. Buscando reverter as adversidades climáticas sofrida pelos produtores para alimentar seus animais, objetivo deste trabalho foi avaliar a produtividade e a qualidade da forragem hidropônica no ecótono Cerrado-Pantanal, buscando determinar a espécie e a solução mais adequada para a região. Foram conduzidos dois experimentos na Universidade Estadual de Mato Grosso do Sul, no município de Aquidauana – MS, em casa de vegetação com tela de sombreamento de 50%. O primeiro experimento foi implementado no mês de março e o segundo no mês de setembro, ambos sendo conduzido por 15 dias. O delineamento experimental foi em blocos ao acaso, em parcelas subdivididas. A parcela foi formada pelas soluções (mineral e orgânica) e as subparcelas foram as populações (100% milho, 100% milho + 8 sementes de mucuna, 100% milheto, 50% milho + 50% milheto, 75% milho + 25% milheto e 25% milho + 75% milheto) com quatro repetições totalizando 12 tratamentos. As parcelas continham 1 m2 e receberam 4 litros de sua respectiva solução durante 11 dias. A população constituída de 25% milho e 75% milheto irrigada com solução mineral apresentou melhor qualidade de forragem quanto a proteína bruta. A população de milho e milho + mucuna obtiveram maior matéria seca independente da solução.

“…Regarding the regression evaluation for the interaction between mineral fertilization and pig deep-litter, there was a linear behavior, showing that with increase in PDL doses, there is also an increment in crude protein contents (Figures 4A and B). Simonetti et al (2016), analyzing the productivity of Mombasa grass under different doses of biofertilizers, found that the highest doses of biofertilizer (200 m 3 ha -1 ) led to differences between the other treatments, evidencing its influence on forage quality for protein content.…”

“…Food NDF content represents the fraction of non-soluble fiber in neutral detergent and can be used by technicians and producers of ruminant animals for balancing diets with adequate dietary fiber contents (Simonetti et al, 2016). In general, both the quality and quantity of dietary fiber present In studies with different grazing heights, Rego et al (2003) found NDF values from 58 to 72% for leaves and from 77 to 83% for stems.…”

The use of pig deep-litter (PDL) in pasture fertilization can be an important alternative from an environmental and economic point of view. This study was conducted to evaluate the fertilization with PDL exclusively or in association with mineral fertilizers on the quality and productivity of Panicum maximum cv. Mombasa. The experiment was carried out in Ipameri, GO, Brazil. The design was a randomized block design in a 2 x 5 factorial scheme with four repetitions, in plots of 24 m². The doses of PDL (0; 5; 10; 15 and 20 Mg ha-1) were tested, with or without fertilization with NPK (50 kg ha-1 of P2O5, 10 kg ha-1 of K2O and 10 kg ha-1 of N). The organic fertilizer was applied broadcast at the planting of the pasture, and the mineral fertilizers were split and applied at planting and as topdressing. Dry mass, crude protein, acid detergent fiber and neutral detergent fiber were evaluated. PDL doses associated with mineral fertilization led to linear increases from 52 to 282% in the analyzed variables and better bromatological composition. PDL application is beneficial to the production of pastures, and increasing applications up to the PDL dose of 20 Mg ha-1 associated with mineral fertilization promoted better quantitative and qualitative results. With exclusive fertilization with PDL, the gains in quality and productivity were more modest.
