Hot and dry climate interferes with the implementation of soybean crops in RS

The hot and dry climate, with partial and variable occurrence of rain, interfered with the dynamics of implementation and the development conditions of soybean crops in Rio Grande do Sul. According to the Conjunctural Information released by Emater/RS-Ascar this Thursday- fair (15/12), in regions where there was no rainfall, planting will resume when the soil regains moisture.

The option to plant in dry soil, using treated seeds, was almost not carried out, as forecasts indicated a likely absence of rain in the coming weeks. In regions where the volume of rain provided adequate moisture content in the soil, sowing continued, and in some locations it is already close to completion. In the State, sowing reached 85% of the projected area.

In most of the State, due to the effects of La Niña, the implantation and development of culture are lagging behind in relation to years considered normal. In this scenario, producers also opted for staggering planting and greater variation in the cycle of the cultivars used, keeping most of them early and using seeds from medium and late cycles to minimize risks.

The greater or lesser presence of humidity also affects the general appearance of the crops. In the east of the state there is better development and fewer signs of water stress. In the Central and Northwest regions, high plant transpiration and low water replacement caused delays in vegetative growth and wilted plants in part of the crops, which only regain turgidity during hours without sunlight.

In phytosanitary terms, herbicide spraying is not being recommended in areas where the soil is very dry, as there may be phytotoxicity for soybeans and a low rate of control of weeds. Furthermore, high temperatures associated with low relative humidity are factors that greatly depreciate applications.
