Brachiarias are forage plants widely used in pastures for livestock. They are generally known for their hardiness and ease of handling. However, growing these vegetables can present challenges in some regions, due to factors such as pests, lack of nutrients and extreme weather variations. In this sense, the adequate choice of the variety of brachiaria for planting becomes fundamental to guarantee the quality of the pastures and the health of the cattle.
Experts explain that, in the early 1970s, the introduction of Decumbens brachiaria represented a true revolution in the pastures of the Brazilian cerrado, enabling the opening of new areas. However, the pastures began to suffer from sharpshooter attacks. From 1984, the arrival of the Marandu brachiaria triggered a second revolution in the sector, providing greater resistance to pests. However, this variety, which became dominant in Brazil, brought other challenges, as it lost excellent characteristics contained in Decumbens pastures, such as adaptability to more acidic soils, resistance to drought and the presence of stolons that root in the soil and perform great ground cover.
These difficulties, however, can already be solved thanks to the hybrid brachiaria Dunamis, a new cultivar developed by Milagro Agro Brasil and the protagonist of the third revolution in the sector. The plant is a hybrid resulting from the crossing between Decumbens and Marandu, being able to offer the producer the best qualities of these two varieties.
The main characteristic of Dunamis, according to Milagro Agro Brasil, is the presence of stolons that root in the soil. These stolons exist in Decumbens, but are absent in Marandu, which is currently the most planted brachiaria in the world. Due to this characteristic, Dunamis can facilitate soil cover, reduce the degradation of the planted area and increase the longevity of the pasture, consequently improving productivity, sustainability and profitability for the cattle rancher. It also has other advantages over other brachiaria, such as:
- Initial growth much higher than that of Marandu and Decumbens;
- Resistance to pasture leafhopper;
- Easy adaptation to low fertility soils (pH 4.8 to 5.5), sandy soils and land with high slopes;
- Better erosion control;
- Greater drought tolerance compared to Marandu;
- Good tolerance to short periods of waterlogging (15 to 30 days) compared to Marandu (3 to 6 days);
- Tolerance to Rhizoctonia (one of the fungi that causes the sudden death of brachiaria);
- Ease of planting in holes in sandy soil and without correction;
- Crude protein contents and digestibility superior to those of Marandu.
Milagro Agro Brasil’s marketing and sales director, Alexandre Hemza, says that customers who already use Dunamis brachiaria have reported benefits for their businesses. “These days, I received a testimonial from a client who planted mombaça, one of the most used grasses for dairy cattle. When he started planting Dunamis and the cows started to feed on this variety, they jumped from a productivity of 8 to 9 liters per day to an average of 12 liters per day”, he says.
Dunamis will also be featured at Agrishow, one of the largest agricultural technology fairs in the world, which should bring together around 200,000 people, in Ribeirão Preto, between the 1st and 5th of May. According to Alexandre Hemza, customers who wish can purchase seeds during the fair under special conditions, which will not be offered throughout the rest of the year. “We are a company that takes technology to the field in an accessible way. In this event, we are going to reinforce this characteristic”, he says. In addition to reduced prices, the customer who closes a deal during the Agrishow will also be entitled to easy payment and delivery in the correct period for planting.
