With the predominance of sunny days, the removal of wheat from the crop occurred quickly in Rio Grande do Sul, evolving towards the end of the harvest and currently reaches 97% of crops harvested.
According to the Joint Report prepared by Emater / RS-Ascar, only in the Campos de Cima da Serra, the last region where wheat is sown and harvested, the crops are in the stage of grain filling and maturation. The harvest should begin in the next few days, but it already shows signs of falling yield and grain quality, as occurred in other regions of the State.
Overall, wheat yields continue to vary widely, averaging less than the estimated range, ranging from 2.2 t / ha to 3.3 t / ha and below-expected quality, with an average pH of around 75. According to Emater, the fall in productivity was due to technological factors, as some cultivars showed much lower yields than expected, and climatic factors, with the occurrence of late frost and high rainfall volumes at maturity. Thus, a large number of producers are requesting surveys to use Proagro.
The canola crops are with the harvest finished in the North region of the State. The average productivity may have a small reduction over the estimated one, although some crops yield higher than expected yield. Generally speaking, producers believe that canola farming should still provide a small final profit.
Barley harvesting is almost complete. The final productivity is below the initial expected, with many ears attacked by diseases and low quality grain, not meeting the standards required by the industry, with a minimum germination of 95%, and probably should be destined to animal feed.
The harvest of white oats is concluded, and the crop is greatly affected by the climatic adversities that occurred during the development and evolution of crops. Productivity reduced in relation to the initial expectation, due to the lodging in several areas that were destined for grains.
Sunflower cultivation begins the maturation of the grains, observed by the senescence of the petals of the chapters and the positioning of the same, accounting for the finalization of the crop cycle. In general, the aspect of the crops is very good in the production regions of the Missions and Northwest Frontier. Sunflower harvesting continues until the beginning of the second week of December, with expected yields of around 1,600 kg / ha.
Summer crops
The development of corn in the State is good, reaching 86% of the area projected for this harvest. Currently, 60% of the implanted crops are in vegetative development and 15% at the beginning of the reproductive stage, with a large part of this already implanted area initiating the issue of the tassel. The period is of high need of water supply for the crop.
The pattern of corn crops is very good, favored by the current good climatic conditions. Pests and diseases are under control. Attention is drawn to the high population density of plants per hectare, around 75 thousand, offering a high yield opportunity, but with a risk of water deficiency and having a highly affected productivity.
In soybean, sowing in the State followed its normal rhythm, favored by meteorological conditions and reaching 68% of the 5.9 million hectares destined to the oilseed crop in RS. Sowing is also found in the winter crop areas of wheat, barley, canola and white oats. There is a predominance of the cultivation of cultivars of cycle of maturation superprecoces, aiming to reduce the fungal treatments.
