Orange trees bloom in some orchards in SP

Cepea, September 17th, 2021 – In early September, orange trees bloomed in some orchards in São Paulo State (SP). These flowers will become the fruits from the 2022/23 season. Cepea collaborators reported higher blooming in irrigated orchards, majorly in northern and northwestern SP.


However, citrus farmers have been concerned about the effects of the weather on flower settlement. In dryland orchards, which count exclusively on rainfall for moisture, precipitation has been insufficient to trigger blooming.


According to Somar Meteorologia (weather forecast agency), rainfall was low in the major citrus-producing regions in SP in the first half of September. Thus, while it does not rain significantly, farmers are investing in plant nutrition in order to help on fruit set.


During fruit set (after blooming), temperatures and soil and air moisture deeply influence production. However, in the last years, high temperatures and rainfall below the average were common, limiting the output, largely in non-irrigated orchards.


Climatempo (weather forecast agency) forecasts rains for the second fortnight of September, and rainfall is expected to be within the average in the month in most citrus-producing regions in Brazil, except in southern SP. On the other hand, according to NOAA (National Oceanic and Atmospheric Administration), there is a 70% chance that La Niña phenomena may return to Brazil until the end of 2021.


In Brazil, La Niña increases rainfall in the northeastern region and delays precipitation in the south. In southeastern BR, the scenario becomes similar to that in the southern area of the country, which concerns agents, in light of the current drought. For citrus farming, this delay may cause more damages to the 2022/23 harvest, since the coming months are critical for the development of trees, when higher moisture is needed.


BRAZILIAN MARKET IN SEPTEMBER – The demand for oranges increased in the in natura market in the first fortnight of September, favored by high temperatures and the payment of workers’ wages early in the month. As regards supply, the hot and dry weather in SP continued to limit the availability of high-quality fruits in the market (most of them are wilted and small-sized). In this scenario, prices increased.
