Spatial and Temporal Evolution of Sowing and the Onset of the Rainy Season in a Region of Large Agricultural Expansion in Brazil

In order to assist in high-yield agricultural management multiple cropping systems, it is essential understand the link between rainy season onset and crops sowing dates, since considerably affects management, yield output. We built crop calendars derived from remote sensing products investigated dates of irrigated rainfed agriculture Western Bahia, a new important frontier Brazilian Cerrado. Crop were obtained green-up 2001 2019. Rainy determined using CHIRPS daily precipitation data. Results indicate that occurs 26 October 15 November starts 17 27 October. Rainfed are strongly correlated particularly affected years where rains delayed. Sowing pixels occur up 25 days earlier than not onset. Irrigated farms shorter window rainfed, with stronger resilience delayed, have adapted their operation towards more intensive efficient water use during season.
