Water excess and its effect on cassava growth and yield

In this study, we aimed to: (i) characterize the effects of water excess soil on cassava growth; (ii) identify management practices that reduce the impact of water excess on cassava yield; and (iii) to know the crop potential yield for the study region in order to quantify the yield loss caused by water excess. Cassava culture stands out in this scenario for being a low-cost crop, which reduces hunger and rural poverty, contributing to socioeconomic development, having been elected by the United Nations Food and Agriculture Organization as food of the century XXL (FAO, 2020; Tironi et al., 2019, Tagliapietra et al., 2019). (2016), and Załuski & Antonelli (2014), respectively, presents positive results in plant growth and development through the adoption of management practices such as the construction of drainage systems and the use of raised seedbeds to minimize the effects of water excess. [...]it is essential to deepen studies and investigations to develop effective water management strategies in cassava cultivation, aiming to increase yield and reduce damage caused by water excess in the soil. In this study, we aimed to: (i) characterize the effects of water excess soil on cassava growth; (ii) identify management practices that reduce the impact of water excess on cassava yield; and (iii) to know the crop potential yield for the study region in order to quantify the yield loss caused by water excess. The soil in the field study area was classified as Hapludalf typie, hydromorphic and poorly drained, with a sandy surface horizon and alluvial clay accumulation.
