PRODUCTION AND YIELD GAP OF CASSAVA CROP (Manihot esculenta Crantz)

According to the Food and Agriculture Organization FAO (2013) the availability of agricultural areas is concentrated only in a few countries with about 90 % of land for agricultural expansion located in Latin America and Sub-Saharan Africa. In Latin America Brazil has a key relevance for food production with high potential for expansion (SAATH; FACHINELLO 2018). However environmental concerns and the preservation of native forests have limited the agricultural expansion thus the appropriated alternative is increasing yields instead of deforestation (SAATH; FACHINELLO 2018). It is important studying the factors that verify the limited and determined factors of the cassava productions and to analyse the key causes of its inter-annual and inter-regional variability or simply called loss of yield. Increasing crops yield means reducing yield losses caused by weather and agricultural management known as yield gap (Yg) (GODFRAY et al. 2010; SENTELHAS et al. 2015).Although the technological and scientific advances the climate is still the most important variable for crops productions (CALDANA et al. 2019; CALDANA et al. 2021).
