“…In previous trials with Mombasa and Tanzania in Thailand (Hare et al 2013;2014;2015), Mombasa always produced significantly higher DM yields than Tanzania, but the quality of Tanzania was always superior. In this trial, Mombasa maintained its higher DM production than Tanzania, but quality of forage from both cultivars was generally similar.…”

A field trial in Northeast Thailand during 2015‒2018 evaluated the forage accumulation and nutritive value of 5 Megathyrsus cultivars, Mombasa, Tanzania, Massai, Zuri and Mun River. Mombasa and Tanzania are commonly grown in Thailand, but Massai, Zuri and Mun River had not been evaluated in Thailand before. Overall accumulated DM yields for the various cultivars over the 3 years were 24,550 kg/ha for Tanzania, 30,900 kg/ha for Massai, 32,700 kg/ha for Mombasa, 35,600 kg/ha for Mun River and 35,700 kg/ha for Zuri. Over 3 wet seasons, Mun River and Zuri accumulated 49% more total DM and Mombasa 35% more total DM than Tanzania. Massai accumulated lower total DM yields than Zuri and Mun River in the second and third wet seasons, similar yields to Mombasa, and higher yields than Tanzania in those 2 seasons. Crude protein concentrations in forage were higher in the dry season than in the wet season and in leaves than in stems. There were no consistent differences in CP% of the various cultivars in wet or dry seasons. ADF and NDF concentrations in the dry season were lower than those in the wet season and leaf ADF and NDF concentrations were lower than concentrations in stems. There were no consistent differences of ADF and NDF concentrations between cultivars throughout the study. This trial showed that both Zuri and Mun River would be ideal replacements for Mombasa and Tanzania in Northeast Thailand, as they would appeal to smallholder farmers for cut-and-carry forage with their upright, broad leaves, and at least similar DM production to Mombasa and superior DM production to Tanzania.

“…For example, B. decumbens , which demonstrated a great capacity for soil coverage and relatively high yields across all sites could be an appropriate choice on degraded soils or soils that are highly susceptible to erosion (Peters et al ., 2010; Shriar, 2007). Meanwhile, M. maximus (Mombasa) demonstrated a high growth potential and high forage yields in most sites, but should not be recommended for use in degraded soils or on steep slopes due to its relatively high nutrient demand and tendency to grow in bunches and thus provide poor soil cover (Hare et al ., 2015). Mulato II has been the grass most highly promoted in El Salvador by government institutions (possibly due to higher forage quality, including crude protein content), but was found in this study to be low yielding on sub-optimal soils and in the environmental conditions of Central America's Dry Corridor.…”

Participatory Evaluation of Improved Grasses and Forage Legumes for Smallholder Livestock Production in Central America

et al. 2018

The International Center for Tropical Agriculture (CIAT) believes that open access contributes to its mission of reducing hunger and poverty, and improving human nutrition in the tropics through research aimed at increasing the eco-efficiency of agriculture.CIAT is committed to creating and sharing knowledge and information openly and globally. We do this through collaborative research as well as through the open sharing of our data, tools, and publications. Summary: 29Smallholder livestock systems in Central America are typically based on pastures with 30 traditional grasses and associated management practices such as pasture burning and extensive 31 grazing. With the rise of the global population and a corresponding increase in demand for meat 32 and milk production, research efforts have focused on the development of improved grasses and 33 the incorporation of legume species that can increase productivity and sustainability of Central 34American livestock systems. However, farmer adoption remains very limited, in part due to the 35 lack of site-specific evaluation and recommendations by local institutions. Using a multi-site, 36 participatory approach this study examined the potential of five improved grasses and five 37 species of forage legumes as alternatives to the broadly disseminated grass Hyparrhenia rufa (cv. 38 Jaragua) in pasture-based cattle systems in western Honduras and northern El Salvador. 39 Improved grasses (four Brachiaria sp. and Megathyrsus maximus) produced significantly more 40 biomass than H. rufa; also four of the five legume varieties evaluated (Canavalia ensiformis, 41Canavalia brasiliensis, Vigna unguiculata, and Vigna radiata) demonstrated high adaptability to 42 diverse environmental conditions across sites. Farmer participatory evaluation offers a valuable 43 means to assess performance of forages and will likely contribute to their improved utilization. 44Future research is needed on more refined management recommendations, pasture system 45 design, costs, and environmental benefits associated with the adoption of these forages in local 46 livestock production systems. 47 48

“…Agronomic and forage nutrition evaluation. Average and maximum values of DMY in the M. maximus collection observed in the Patía valley in Colombia ranged from 5.09 to 7.82 t/ha (Table 2) and were higher than those recorded in Brazil (Macedo et al 2017) and Thailand (Hare et al 2015). Nevertheless, in Vietnam (Asia), there are reports of up to 12.8 t/ha with 42 days' regrowth (Van Man and Wiktorsson 2003).…”

Agronomic, nutritional, and environmental aspects are integrated to promote sustainable tropical grassland production. Biological nitrification inhibition (BNI) is a plant-based strategy to improve nitrogen use efficiency by grasses in which they suppress the pace of soil nitrification via exudation of inhibitory compounds. To evaluate the effect of BNI on the productive performance of Megathyrsus maximus under field conditions, we evaluated a collection of 27 germplasm accessions and commercial cultivars of the forage grass in the dry tropics of Colombia. We measured plant yield dry matter, nutrition quality parameters, and nitrification rates of soil at 22 months after pasture establishment. Our results highlighted germplasm accessions of superior agronomic performance (for dry matter production and nutrition quality) and high capacity to decrease nitrification. Although no relation was observed between agronomic aspects, nutritional aspects, and nitrification rates, we conclude that there is no agronomic or nutritional penalty on environmentally friendly grasses, and BNI could be adopted as a target trait in plant breeding programs toward the development of eco-efficient forages and contribute to the sustainable intensification of livestock systems.
