Technology enables meiosi to reduce farming costs

The survey was conducted in 2021 by Agricultural Institute (IAC)with 77 companies, totaling more than 340 thousand hectares in renewal areas throughout Brazil (1 in Alagoas, 1 in Bahia, 8 in Goiás, 2 in Mato Grosso, 4 in Mato Grosso do Sul, 11 in Minas Gerais, 15 in Parana, 3 from Pernambuco, 31 from São Paulo and 1 from Tocantins), indicates that 77% of the producers surveyed said they had used Meiosis (The exchange method operates simultaneously) accounted for 26% of the renovation areas in 2021. According to the survey, 53% of the districts were used MPB (pre-spread seedlings)to ensure greater sanity and efficiency of multiplication.

According to the researchers, in most cases, these areas will generate farmer Without defects and with a good plant, it will produce in turn cane fields More powerful and healthier. In addition Meiosis It allows the cultivation of an intermediate crop with a shorter cycle, which adds income to producers in the same area and still serves, in many cases, as a green manurewhich leads to gains in productivity in the next years.

It was created in 1983/1984, at a time when the Internet had not yet reached Brazil, without tools such as the Global Positioning System (GPS), Interleave-Rotational method running at the same time (Meiosi), I found it difficult to spread across the country. Since the system relies on precision in line marking cane Subsequently, the grooves in the spaces used for crop rotation, and the lack of these techniques, made their implementation difficult.

In the 1990s, positioning technologies in machines were not yet available to everyone. But recently, these technological barriers have been broken down and meiosis has gained a niche and established itself as a great ally for producers, bringing many benefits, in addition to reducing farming costs. Another important point was a generalization MPBs (pre-sprouted seedlings) This makes it possible to transport high-quality materials to new areas without having to process the stalks to collect them nurseries.

How did it all start

Jose Emilio Teles de Barcelos

About the professor and agricultural engineer, Jose Emilio Teles de Barcelossince it was created in 1983, the Meiosis Already brought important appeals in its favor: crop rotation, production healthy seedlings, Savings on transplanting seedlings, savings in food production, savings on growing crops.

At the time, it was also conveying the message of minimizing society’s ‘fee’ on the effects of ‘monist culture’. sugar cane tree, introducing food production in these areas. It still has an environmental appeal with green cover Reducing soil compaction with legumes (soybeans, peanuts and crotalaria).

According to Professor Barcelos, in 1983, the IAA-PLANALSUCAR Sugarcane Experimental Plant In Triângulo Mineiro, where the Agua Lemba farm is currently located, Federal University of Oberlandia, was the first region in which the meiosi system was installed. “On that occasion, the soybean seed was provided, and the grower and operator was provided by Grupo Algar de Uberlândia, in exchange for the harvest of the grain in the cultivated area,” Barcelos recalls.

The work was published in the March 1984 issue of Revista Saccharum (Technological Journal of the Sugar and Alcohol Industry).

From 1984 to 1990, Professor Barcelos completed his master’s degree in UNESP-Jaboticabal-SP, With the teacher as a guide doctor. Ailto A. Casagrande. During this period, in the second half of 1984, it was Meiosisas a master’s research project, installed in Fazenda Santa Isabel, in the municipality of Guaíba – SP, owned by Roberto RodriguezFormer Minister of Agriculture. At that time, treatments were studied using cane/soy; Sugarcane/Peanuts and Sugarcane/Fallow. In 1990, Professor Barcelos defended this topic in his master’s thesis.

According to Barcelos, there were not many practical applications at first, as the project was mainly limited to written business records. “We had our first publication in the journal Saccharum, in 1984 and after that the master’s experiment was developed at Fazenda Santa Isabel (by Dr. R. Rodrigues) and supplemented the cultivation of the area with Meiosis by directors (José Ap. Coelho and José Bício); They continued to plant it in the following years. Until he was “discovered” by Globo Rural and reported on national television,” he says.

“Then we took the idea of ​​meiosi to Power plant in São Martinho. agronomist Julio Campanhau He was responsible for its confirmation and dissemination through “field days” and other events. at Colorado Factory About 2500 hectares were planted with meiosi in 1993-1994 under the guidance of technician Jose Mauro G Ferreira (who accompanied us at the first meiosi installation in Uberlândia in 1983-84 by IAA-Planalsucar), he explained.

The system was also implemented by Assis Co-operative Society – SP, São Jose da Estiva – SPand many others (producers, companies, cooperatives, Power plantsAnd IAC, among others). In 1996, meiosi was presented at an international conference in Miami – USA.

Professor Barcelos listed some considerations about the system:

“The Meiosis (with pulses and other crops) in areas of repair cane fieldsallows significant gains in food production within sugar cane area; Makes room for seedlings to multiply from cane At the same planting site, at the same time it contributes to obtaining increases in food production in sugar cane areas; Promotes a very large economy in the transportation of seedlings cane For agriculture promotes to reduce the costs of installing a crop cane, 30-35% for conventional farming; Facilitates the performance of “ROGUING” to eliminate potential diseases and/or miscellaneous mixtures in the dual lines of cane Ensuring better plant health for everyone cane field. Double lines for cane Give Meiosis They practice crop erosion control alternately among themselves,” explains Barcelos, who is very pleased with the current expansion of the technology he pioneered 38 years ago.

“I think that Meiosis, in 83/84, it was a well-intentioned “kick”, which, thanks to God and the participation of many in its “cut”, gave excellent results; Which makes us very happy,” concludes the professor Jose Emílio Teles de Barcelos.
