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 the third flowering of coffee crops and in the same way as the previous ones: under a deficit situation very high water content.
A phrase widely used in coffee growing and which reflects the current reality is: ‘’ Coffee crops can withstand dry, what they cannot withstand is little water ‘’. 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 the setting of the blossoms, which explains the chaotic scenario observed in Arabica crops in Brazil.
Even with low rainfall, linked to cloudy weather, these stimulated the development of at least three significant and main flowering plants in Brazil. In general, the blossoms opened in this situation of severe water deficit and, as a consequence, there was intense burning of flower buds and low flowering.
Much is heard that we will have to wait for the rains of late October and early November to know what will happen, however, no: there is no need to wait any longer since the three main flowering areas of coffee crops have already occurred and, in their the vast majority, under severe water stress.
What has to be measured from now on is the quantification of losses. It is known that in some regions the losses were greater and in others smaller, however, in the general picture, the production of 2021, naturally lower due to the negative bienniality is even more affected by the situation of high water deficit associated with the high temperatures observed at the time flowery.
