- Abstract
For a crop to reach its maximum productive capacity, water availability in the root zone is necessary. Thus, water deficit is a factor that most limits the potential development of a crop. In this context, this study aimed to determine the best time for soybean cultivation in the region of Uberlândia-MG, considering a historical series of 40 years (1980 to 2020) climatic data, through the analysis of water deficits via water balance daily sequential. For the 40 agricultural years studied, the daily sequential water balances were calculated, considering four different cropping dates: November 1st, November 15th, December 1st, and December 15th. For each cultivation date, water deficits were analyzed throughout the crop cycle, and in phenological sub-periods (S-V1/V2; V2-R1; R1-R5/R7; R7-R8). For all sowing dates, water deficit was observed in almost all soybean phenological sub-periods. For the region of Uberlândia-MG, the planting dates between November 15th and December 1st showed the lowest water deficits in the two initial phases/sub-periods.
