The low rainfall observed from the second half of March to the second half of October has already severely compromised the 2021 harvest. At this point it is possible to observe the occurrence of 3 flowerings all under a water deficit situation.
A phrase widely used in coffee growing and which reflects the current reality is: ‘’ Coffee crops can withstand dry, what they cannot withstand is light and irregular rains ‘’. In the year 2020, it was possible to observe small rain events in late August, late September and mid-October. However, it seems that these rains were not enough to guarantee a good opening and setting of the flowers, which explains the chaotic scenario observed in the Arabica crop of Brazil.
The low rainfall, linked to cloudy weather, stimulated the development of at least three significant and main flowerings.In general, the blossoms opened under a severe water deficit and, as a consequence, there was intense burning of flower buds and low fixation.
We hear that we will have to wait for the rains of late October and early November to analyze the losses, however, no: there is no need to wait any longer since the three main flowerings have already occurred and, in their vast majority, under severe water stress.
What has to be measured now is the losses. It is known some regions fared better than others. In general the 2021 production already a negative biennial year should see further production losses as a result of water deficit and high temperatures when the plants were flowering.
