“…In the present study, grasses were harvested at 7-cm stubble height, and harvesting every 14 d compared with every 42 d resulted in a decrease of 50 to 63% in HA. A large reduction in HA can ultimately be associated with decreased stand vigor in the long term (Sollenberger, 2008).…”

Grasses within the Cynodon genus are widely used perennial forages, and ‘Tifton 85’ (Cynodon spp.) is one of the most popular commercial cultivars. Jiggs and Vaquero are new C. dactylon (L.) Pers. grasses, but there is little information comparing their performance with Tifton 85 under tropical conditions. The objectives were to describe and explain variation in seasonal herbage accumulation (HA) and nutritive value of irrigated Tifton 85, Jiggs, and Vaquero bermudagrasses in response to harvest frequency (14, 28, and 42 d). The trial was performed for 2 yr in Piracicaba, Brazil, on a Kandiudalfic Eutrudox soil. In the warm season, total HA of Jiggs was similar to Tifton 85, and both were more productive than Vaquero. Under the 42‐d frequency, Jiggs had greater annual HA than the other grasses (28.5 vs. 23.7 and 20.1 Mg ha−1, for Tifton 85 and Vaquero, respectively), but when harvested every 28 d, Tifton 85 and Jiggs HA were similar (18.5 Mg ha−1). For the 42‐d harvest interval in the cool season, Jiggs had the greatest HA (10.2 Mg ha−1). Less frequent harvests in both seasons resulted in greater HA. Tifton 85 had a greater proportion of leaves than Jiggs and greater in vitro digestible organic matter (IVDOM) than the other grasses in the warm season. Considering these responses, harvest frequency of Jiggs and Tifton 85 should be ∼28 d in the warm season, while that of Vaquero should be ∼42 d. No single harvest management will be appropriate for all Cynodon grasses.

“…Brachiaria cultivars are widely used in tropical areas mainly due to their tolerance of low fertility acid soils in addition to their high forage accumulation and nutritive value when well fertilized and managed, and high viable seed production (Nunes, Boock, Penteado, & Gomes, ). Cynodon cultivars are also very important pasture options worldwide mainly due to their adaptability to warm and cold conditions ranging from tropical to subtropical regions including Africa, Asia, Australia and the Americas, along with easy establishment, high potential production and nutritive value (Sollenberger, ).…”

Brachiaria and Cynodon are two of the most important pasture grasses worldwide. Computer model simulations can be used to study pasture species growth and physiological aspects to identify gaps of knowledge for genetic improvement and management strategies. The objective of this research was to compare the performance relative to calibrated parameters of the CROPGRO‐Perennial Forage Model (CROPGRO‐PFM) for simulating three different species (“Marandu” palisadegrass, “Convert HD 364®” brachiariagrass and “Tifton 85” bermudagrass) grown under similar management. The field experiment consisted of two harvest frequencies, 28 and 42 days, under irrigated and rainfed conditions. Data used to calibrate the model included regular forage harvests, plant‐part composition, leaf photosynthesis, leaf area index, light interception and plant nitrogen concentration. The simulation of biomass production of the three grasses presented d‐statistic values higher than 0.80, RMSE ranging from 313 to 619 kg/ha and ratio observed/simulated ranging 0.968 to 1.027. Harvest frequency treatments of 28 and 42 days were well simulated by the model. A sensitivity analysis was conducted to evaluate the most influential parameters needed for model calibration and to contrast the grasses, showing that the differences among the three grasses are mostly driven by plant‐part composition and assimilate partitioning among plant organs.

“…Mineral fertilizers, especially those containing nitrogen, increase both forage productivity and nutritional value (SOLLENBERGER, 2008). However, nitrogen use is often limited by its high cost, with the average price per ton having increased by more than 500% within the last 20 years in Brazil (ANDA, 2015).…”

The objective of this study was to evaluate forage production and root accumulation in Brachiaria decumbens cv. Basilisk with swine wastewater as a fertilizer. The experiment was conducted into a greenhouse in Federal Institute of Education, Science and Technology of Southeast of Minas Gerais, Rio Pomba Campus. Pots with 6 dm -3 volumes were used as experimental units. Were used a randomized block design with four replications. Were studied four swine waste doses (0, 225, 450 and 675mL pot -1 ) over four regrowth cycles. The dry matter production of the aerial part, forage accumulation rate, crude protein and dry matter production of roots increased with the highest swine waste doses being around 670, 742, 160 and 465% respectively from lower to higher dose. There was interaction between swine waste and regrowth cycles for plant height and tillering, and in all regrowth cycles responded positively with increasing swine waste doses. Applying swine waste on pastures is therefore a viable alternative to increase productivity of B. decumbens cv. Basilisk, it recommends the use of swine waste corresponding to the dose of 675mL pot -1 to maintenance pastures. Key words: Brachiaria. Effluents. Fertigation. Forage yield. ResumoObjetivou-se com este trabalho avaliar a produção de forragem e acúmulo de raízes em Brachiaria decumbens cv. Basilisk com o uso da água residuária de suínos como fertilizante. O experimento foi conduzido em casa de vegetação no Instituto Federal de Educação, Ciência e Tecnologia do Sudeste de Minas Gerais, Campus Rio Pomba. Vasos com volume de 6 dm -3 foram utilizados como unidades experimentais, utilizou-se o delineamento em blocos casualizados com quatro repetições. Foram estudadas quatro doses de água residuária (0, 225, 450 e 675 mL vaso -1 ) durante quatro ciclos de rebrotação. A produção de matéria seca da parte aérea, a taxa de acúmulo de forragem, a proteína bruta e a produção de matéria seca de raízes aumentaram com as doses de água residuária, com aumentos de cerca de 670, 742, 160 e 465% respectivamente da menor para a maior dose. Houve interação entre doses de água residuária e ciclos de rebrotação para as variáveis, altura das plantas e densidade populacional de perfilhos, sendo que em todos os ciclos de rebrotação, responderam positivamente com o aumento das doses de água residuária. A aplicação de água residuária suína é uma alternativa viável para aumento da produtividade da B. decumbens cv. Basilisk, recomenda-se o uso de água residuária correspondente à dose de 675 mL vaso -1 na manutenção das pastagens. Palavras-chave: Brachiaria. Efluentes. Fertirrigação. Produção de forragem.
