The extreme conditions are affecting the wheat crop and causing concern among farmers and technicians in the region.
The beginning of August coincided with an extraordinary climatic event in the core region, with record highs that had not been recorded in the past 100 years. These high temperatures make for an unusually warm July, which has doubled the region’s monthly average.
According to a report by the Rosario Stock Exchange’s Strategic Guide to Agriculture, these extreme conditions are having an impact on wheat cultivation and are causing concern among farmers and technicians in the region.
In the present phase of cultivation, where 30% of the wheat pieces have started tillering and 70% have fully tilled, high temperature can affect its development. According to experts consultation, wheat needs cool hours to produce tillers, but high temperature in July is accelerating the development and growth rate of the crop, which may shorten the tillering period.
This rapid tillering may result in fewer ears per square meter and wheat yield may be affected. At some places, a 50% reduction in tiller production has been observed as compared to the normal year. Furthermore, the situation is more serious in areas that received more than 30 mm of rain in July, as concerns have been raised about the emergence of fungal diseases such as orange rust, which may require multiple control applications.
The scarce supply of water for a large part of the producing areas of the mainland is also a worrying factor. Medium-term forecasts indicate that low water levels will continue into the first decade of August, further affecting crop conditions.
Thus, record temperatures and water scarcity are creating an uncertain scenario for wheat cultivation in the core region. Farmers and technicians are monitoring weather movements and taking measures to minimize potential negative impacts on wheat yield and quality. The situation requires careful and adaptive management by producers to meet the challenges posed by a changing climate and guarantee food security in the region.
