In this interview, Mwihaki Mundia, BecA-ILRI Hub’s Communications Officer, sits down with Sita Ghimire, who heads the Brachiaria research and development program at the Biosciences eastern and central Africa – International Livestock Research Institute (BecA-ILRI) Hub, to talk about the origins of this important grass and how it contributes to more milk and meat production in livestock.

Mundia: Maybe you could start by sharing a brief history of Brachiaria grass?

Sita: Brachiaria grass is a tropical forage that is native to Africa. It was introduced to America and Australia in the 1800′s. Through Australia, many species were later introduced to Asia and the south Pacific region. The use of Brachiaria for commercial pasture production only began in Africa at the start of the twenty-first century.

M: How many Brachiaria species currently exist in Africa?

S: There are seven species of African origin, namely, B. arrecta, B. brizantha, B. dictyoneura, B. decumbens, B. humidicola, B. mutica and B. ruziziensis. These are all used as fodder for livestock.

M: Why did BecA-ILRI Hub choose to work with Brachiaria grass as a means of improving livestock productivity in sub-Saharan Africa (SSA)?

S: Low livestock productivity has plagued sub-Saharan Africa for a long time, creating amongst other things, a severe food shortage for one of the fastest growing human populations in the world. Some of the major factors that contribute to these are feeds shortage and low-quality feeds. Brachiaria provides a solution because it produces a large amount of high-quality biomass that improves the availability of quality feed, its high nutrient value increases livestock productivity of meat and milk and reduces the overall carbon footprint of the livestock production system. Brachiaria additionally tolerates extreme climatic conditions and grows well in low fertile soils. It makes for a great substitute to other forage grasses such as Napier grass which is widely cultivated in sub-Saharan Africa.

M: Would you recommend Brachiaria grass over other forage crops e.g., Napier grass that has been a popular forage for a long time in East Africa?

S: Though Napier grass is very popular in East Africa, its productivity has been on the decline over the years due to smut and stunt disease attacks. The introduction of Brachiaria grass has provided an additional forage option to farmers and helped to bridge the livestock feed supply gaps especially during the dry seasons. Brachiaria grass is one of the top-ranked tropical forages for nutritive value, livestock productivity and climate change adaptation. It is suitable for both grazing and cut and carry systems.

M: What are the main activities that the Climate-smart Brachiaria program at BecA-ILRI Hub carries out?

S: The program provides technical support to National African Research Systems (NARS), non-governmental organizations, and the private sector on Brachiaria grass production and forage biosciences; carries research on Brachiaria grass diseases management; develops Brachiaria-legume cropping system for soil fertility management; identifies Brachiaria seed production niches in Africa; and discovers and uses plant beneficial microbes to enhance resilience and productivity of Brachiaria grass in sub-Sharan Africa.

M: Most livestock farmers in SSA are small-scale producers who do not have much land to grow their food let alone grow fodder, how do you encourage them to adopt Brachiaria grass?

S: The transformation of the livestock sector in Africa depends on intensification of livestock production systems. Improved forages like Brachiaria grass are a great resource that play a major role as a source of high-quality feed at a low cost. Planting Brachiaria grass in farmlands improves feed availability, enhances livestock productivity, and generates income for livestock farmers. It also protects soil from erosion and sustains soil fertility. Due to these benefits many livestock farmers especially those with smaller land sizes are dedicating more land under Brachiaria grass, with some farming it in place of staple food crops.

M: How many varieties/cultivars of Brachiaria are available to farmers in Kenya and how many other countries in SSA have benefitted from the Climate-smart Brachiaria program?

S:  Basilisk, MG-4, Piata and Xaraes are the Brachiaria varieties that are being promoted by ILRI and Kenya Agricultural and Livestock Research Organization (KALRO) in Kenya. These cultivars are currently undergoing the registration process in Kenya. The seeds of these cultivars are available in limited quantities in Kenya through KALRO. Hybrid seed cultivars like Mulato II, Cayman and Cobra are also being sold in Kenya.  So far, about 40,000 farming households in 18 countries in SSA are beneficiaries of the Climate-smart Brachiaria program.

M: How else can farmers use this “wonder grass?”

S: Brachiaria grass can be used as a bioenergy crop to produce biofuel.

It can also be used in crop protection, soil conservation and has great environmental qualities.

Farmers can use Brachiaria to generate income by producing and selling hay. Additionally, the production of rooted tillers as a means of planting materials has recently emerged as a new avenue for agro-business for youth and women in the SSA region.

M: How long does it take for Brachiaria grass to grow to its full height and nutrient potential after planting?

S: The height and time it takes for Brachiaria to attain it is influenced by various factors such as the variety, altitude, soil fertility and other agro-climatic conditions. At the ILRI Nairobi campus, the grass grows to a full height of 1.8 metres. Most varieties take about four to five months to attain their full height.  The nutritive value of forage declines as it matures, it is therefore important to identify the right harvesting time with the perfect balance of biomass and nutritive value.  For good quality hay, Brachiaria should be harvested prior to flowering.

M: What are some of the challenges that farmers might expect to face while growing Brachiaria grass?

S: The major challenges could be pests and diseases and a decline in soil fertility if manure and fertilizers are not applied on a regular basis.

Researcher using skills gained at BecA-ILRI Hub to hasten adoption of improved Brachiaria grass varieties in Tanzania http://localhost/becahub/blog/researcher-using-skills-gained-at-beca-ilri-hub-to-hasten-adoption-of-improved-brachiaria-grass-varieties-in-tanzania/ http://localhost/becahub/blog/researcher-using-skills-gained-at-beca-ilri-hub-to-hasten-adoption-of-improved-brachiaria-grass-varieties-in-tanzania/#comments Tue, 27 Oct 2020 19:31:16 +0000 Mwihaki Mundia http://hub.africabiosciences.org/blog/?p=1089

With an area of 885,800 km2 and a population of 58,458,191 people, Tanzania is one of the largest and most populous countries in Africa. Crop and livestock farming is the main source of livelihood for most Tanzanians. The country’s large livestock population includes 25 million cattle, 16.7 million goats, and eight million sheep.

The main source of feeds for livestock in Tanzania is natural pastures, which are found in the country’s vast rangelands. But these feed sources are often of poor quality and insufficient, especially in the dry seasons. Additionally, conversion of natural pasture into crop production and non-agricultural use areas, and the degradation of pasture due to overgrazing and poor management have reduced the feed available to the country’s livestock.

One step towards addressing the shortage of quality animal feeds in Tanzania is by establishing the available alternative feed resources. Walter Mangesho, a senior livestock research officer at the Tanzania Livestock Research Institute (TALIRI) and a former Africa Biosciences Challenge Fund (ABCF) fellow at the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub, is assessing the Brachiaria grass ecotypes in Tanzania and their morphological and genetic characterizations.

In addition to establishing the types of Brachiaria grasses in the country; Mangesho’s research aims to improve selected Brachiaria grass cultivars, which have high biomass production potential, are nutritive to livestock and resilient to climate change. His goal is to avail the improved Brachiaria varieties to smallholder farmers in Tanzania who will use them as feed to improve the productivity of their animals. ‘I am determined to work towards solving the major livestock challenges in Tanzania, which include a shortage of quality feeds,’ he said

His research, which started in Dodoma, has so far identified and collected 142 Brachiaria ecotypes from 10 regions of Tanzania. These ecotypes are now maintained in a field at TALIRI in Tanga, Tanzania. All the ecotypes were characterized for morphological characteristics and genetic diversity. A subset of the ecotypes with superior phenotypes have been selected and are currently being multiplied for further evaluation.

‘While at the BecA-ILRI Hub, I worked with a team of highly-qualified researchers, mentors and trainers who helped me in molecular biology and genomics research that I had no prior experience with. They strengthened my morphological data collection skills,’ Mangesho remembers of his time as an ABCF fellow at BecA-ILRI Hub.

He was supervised by BecA-ILRI Hub’s Sita Ghimire, Cathrine Ziyomo and Nasser Yao. Jonas Kizima from TALIRI and Angelo Mwilawa from Ministry of Livestock and Fisheries, Tanzania also supervised his genomic and morphological data collection while at the hub.

‘I hope to start multi-location trials in December 2020, once the Brachiaria cultivars are ready,’ remarks Mangesho about his next plans for the near future.

Growing climate-smart Brachiaria in Rwanda: BecA-ILRI Hub project to improve livestock production in East Africa http://localhost/becahub/blog/901/ http://localhost/becahub/blog/901/#comments Tue, 18 Jul 2017 08:06:39 +0000 Ethel Makila http://hub.africabiosciences.org/blog/?p=901 In the ‘Land of a thousand hills’ where the largely steep landscape  has led to severe erosion, finding sufficient feed to support the growing dairy industry has been a major challenge to smallholder farmers.

However, a visit to farmers in Eastern and Southern provinces of Rwanda during the country’s dry season in July revealed that the climate smart Brachiaria grass—or ivugbwe as it is known locally—has the potential to extend forage availability throughout the year.

Rwandan dairy farmers have been participating in a research project to assess the performance of best bet varieties of Brachiaria grass for different agro-ecological regions in Rwanda. The Swedish funded project on ‘Climate smart Brachiaria grass to increase livestock production in East Africa’ was led by the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub and implemented in collaboration with the Rwanda Agriculture Board (RAB).

In this 5-minute video, the farmers talk about why Brachiaria grass has quickly become a favourite forage for their livestock.

Climate-smart Brachiaria grass to help Kenyan farmers withstand global warming effects http://localhost/becahub/blog/climate-smart-brachiaria-grass-to-help-kenyan-farmers-withstand-global-warming-effects/ http://localhost/becahub/blog/climate-smart-brachiaria-grass-to-help-kenyan-farmers-withstand-global-warming-effects/#comments Thu, 20 Apr 2017 10:01:20 +0000 Ethel Makila http://hub.africabiosciences.org/blog/?p=849

A recent study by the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub and the Kenya Agricultural and Livestock Research Organization (KALRO) shows that farmers in semi-arid region of Kenya could stall the adverse effects of climate change on their farms by planting drought-tolerant Brachiaria grass.

The study shows that Brachiaria grass not only improves the productivity of livestock but that it also contributes to improved soil health. Arid and semi-arid lands (ASALs) make up 83 per cent of the total land area in Kenya, which have marginal to low potential for crop production. The soils in these areas are low in plant nutrients and are prone to erosion.

The report Effects of Brachiaria grass cultivars on soil microbial biomass carbon, nitrogen and phosphorous in soils of the semi arid eastern Kenya is one of a compilation of 24 papers published on diverse studies carried out on Brachiaria grass with regards to its adaptation to drought; its impact on milk and meat production; its role in improving soil quality; and establishment of seed production systems for increased availability of the grass seeds and income generation.

Sita Ghimire, a co-author and co-editor of the report and senior scientist at the BecA-ILRI Hub leading the Brachiaria research, says the report is a culmination of pioneering research on the forage in East Africa.

Brachiaria has been used to transform livestock production in South America,’ says Ghimire, ‘however, despite the immense benefits it demonstrated in that region, the true potential of this grass is yet to be realized in its motherland, Africa.’

Livestock production in Kenya accounts for 10 per cent of the gross domestic product (GDP). With growing population, increasing affluence and changes in food habits there is an increasing demand for livestock products. Over 70 per cent of all the livestock in Kenya is found in ASALs, necessitating research to develop forage options that will sustain increased livestock productivity in the face of climate change.

The collaborative research of the BecA-ILI Hub and KALRO demonstrates that the cultivation of Brachiaria grass improves soil quality by increasing the amount of plant available carbon, nitrogen and phosphorous.

Improved Brachiaria grasses broaden horizon for Kenya’s livestock sector http://localhost/becahub/blog/improved-brachiaria-grasses-broaden-horizon-for-kenyas-livestock-sector/ http://localhost/becahub/blog/improved-brachiaria-grasses-broaden-horizon-for-kenyas-livestock-sector/#comments Thu, 24 Sep 2015 17:41:25 +0000 Ethel Makila http://hub.africabiosciences.org/blog/?p=484 Farmer harvesting Brachiaria grasses in Kenya

The meat and milk production of a cow is only as good as the feed it gets. Through a project led by the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub, dairy farmers in the semi-arid regions of Kenya are discovering that Brachiaria, the grass which transformed the livestock industries of Brazil and Australia, can turnaround their low production levels.

Brachiaria grasses are highly nutritious, possessing about 12 per cent protein at harvest which can be sustained over a long period as compared to the commonly used Napier grass whose protein concentration starts diminishing after about four months. The leaves, which form a greater proportion of the plant, are also more palatable and easily digestible. Since Brachiaria grasses thrive all year round, farmers are able to enjoy a constant supply of animal fodder. After a bumper harvest, Brachiaria can easily be dried in the sun and conserved as hay for sale or future use.

Brachiaria grass is not only good for livestock, but has proven useful in the alleviation of the effects of greenhouse gas emissions and ground water pollution. The high amounts of biomass produced by the grass sequester carbon and enhance nitrogen use efficiency through biological nitrification inhibition (BNI).

Through the Swedish funded research project, scientists from the BecA-ILRI Hub, Kenya Agricultural and Livestock Research Organization, Rwanda Agriculture Board, International Centre for Tropical Agriculture (CIAT), Grasslanz Technology Limited and AgResearch (New Zealand), are developing varieties of Brachiaria grasses that are well suited to different local environments across eastern Africa. The project aims at promoting the mass cultivation of the grass in Kenya and other African countries so that the continent can eventually also reap the benefits of her native grass.

Kenyan farmers reap rewards of the amazing Brachiaria grasses http://localhost/becahub/blog/kenyan-farmers-reap-rewards-of-the-amazing-brachiaria-grasses/ http://localhost/becahub/blog/kenyan-farmers-reap-rewards-of-the-amazing-brachiaria-grasses/#comments Tue, 16 Jun 2015 12:02:34 +0000 Ethel Makila http://hub.africabiosciences.org/blog/?p=420 K24 Journalist Violet Otindo highlights the changing fortunes of dairy farmers using Brachiaria grasses to feed their animals in Kenya.

Click here to view the embedded video.

Preliminary data from dairy farmers participating in on-farm evaluations of Brachiaria grasses in Kenya shows that the nutritious grasses contribute to increased milk production.

The on-going research program on Climate-smart Brachiaria Grasses to Increase  Livestock Production in East Africa conducted by the BecA-ILRI Hub in collaboration with the Kenya Agricultural and Livestock Research Institute (KALRO); Rwanda Agriculture Board (RAB) ; International Center for Tropical Agriculture (CIAT), Colombia; and Grasslanz Technology Limited, New Zealand has engaged smallholder farmers in cultivating the grasses as major livestock feed sources and as a source of household cash income through the seed production.

The Swedish funded program has been successful in, together with farmers, identifying best bet varieties for different agro-ecological regions and creating awareness among the farmers, researchers, extension agents, policy makers and politicians on the significance of Brachiaria grasses to support a growing dairy industry. Through the project, farmers have discovered that the Brachiaria grasses not only preferred by animals but  also grow better than most forage in marginal soils of semi-arid and sub-humid environments that are common in most of Sub-Saharan Africa.

In this four minute video, K24 journalist Violet Otindo talks to Albanus Nduva from Kanzalu village of Machakos County in eastern Kenya, one of the 1200 farmers in Kenya who have been involved in participatory on-farm evaluations of Brachiaria grasses as pasture and recording the milk production data Otindo also gets insights from BecA-ILRI Hub scientist Sita Ghimire who leads the program and Donald Njarui from KALRO, Kenya as to why Brachiaria grasses are good for the environment.

Welcome home Brachiaria! Home coming of Africa’s “super” grass http://localhost/becahub/blog/welcome-home-brachiaria/ http://localhost/becahub/blog/welcome-home-brachiaria/#comments Tue, 28 Oct 2014 19:52:50 +0000 Ethel Makila http://hub.africabiosciences.org/blog/?p=280 “The hitherto overlooked Brachiaria grasses have returned home to Africa and have been warmly embraced by smallholder dairy farmers in eastern Africa.”

Presenting a paper co-authored by nine scientists from seven institutions including the BecA-ILRI Hub, Dr Brigitte Maas from International Center for Tropical Agriculture (CIAT) gave an overview of the research, successes and challenges of adopting improved Brachiaria hybrids Mulato and Mulato II in the African context during the 6th All Africa Conference of Animal Agriculture in Nairobi on 27 October 2014.

Brachiaria grasses have higher nutrient content than most commonly used forages. They are adapted to drought and low fertility acidic soils. These grasses are good for the environment as they enhance nitrogen use efficiency, sequester carbon, and reduce greenhouse gas emission and ground water pollutions. These attributes make Brachiaria one of the most widely cultivated forages in South and Central America, and Australia where they have been shown to increase milk and meat yields in cattle.

Re-introducing Brachiaria grasses to their native home
Despite the fact that they are native to Africa and that they occur plentifully across many regions of sub Saharan Africa, these grasses are yet to be explored and fully utilized as forage on the continent. However, thanks to the implementation of a Swedish funded research program “Climate-smart Brachiaria grasses for improved livestock production in East Africa” which is led by BecA-ILRI Hub in partnership with CIAT; Kenya Agricultural and Livestock Research Organization (KALRO); Rwanda Agriculture Board (RAB); and Glasslanz, the anonymity of these “wonder grasses” is coming to an end. The heightened publicity of the importance of Brachiaria grasses and as a strategy to mitigate the effects of climate change has resulted in substantial interest in these grasses among farmers, researchers and policy makers across the continent.

While improved varieties developed in Latin America are being tested in Africa, challenges from pests and diseases have been observed on these imported varieties. The grassed developed in South American conditions have already been observed to be vulnerable to spider mites; sorghum shoot fly, and a number of fungal diseases that are currently in the process of identification. This has necessitated a deeper investigation into locally available diverse genetic resource in Africa to identify the pest and disease resistant varieties.

Finding the best local varieties for the African context

Since Africa hosts a high genetic diversity of Brachiaria, the way forward would be the utilization of this untapped genetic resource to breed varieties that are suitable to the African context. The BecA-ILRI Hub-led project is exploring local ecotypes and gene bank accessions of African origin for drought tolerance, pests and disease resistance and biomass yields. This program consists of four main components – evaluating Brachiaria genotypes for drought tolerance and adaptation to marginal soils; evaluating varieties for biomass production, animal nutrition (including feeding experiments) and seed production; identification and use of phytobiomes for potential agricultural applications as bio-fertilizers, bio-pesticides and bio-yield enhancement agents; and the building the capacity of African scientists to conduct research on Brachiaria grasses.

This collaborative research effort is giving renewed hope to millions of smallholder livestock farmers across eastern Africa who operate smallholder crop-livestock mixed farms on less than 10 ha and are at pains to increase their production in a set up where natural grazing is limited or no longer available

During the 22nd International Grasslands Congress held in Sydney, Australia from 15-19 September 2013, Sita Ghimire, a plant pathologist and senior scientist with the “Climate-smart Brachiaria grasses for improving livestock production in East Africa” program presented a poster about the possibilities that these highly nutritious grasses present.

By using the genetic diversity of Brachiaria grasses and endophytes found within the host (beneficial microorganisms growing within the plants) the research aims to enhance the drought resilience of the grasses; reduce the conversion of soil nitrogen to greenhouse gas, nitrous oxide; and possibly develop microbe based pesticides and fertilizers with wider applications.
