“…P is essential for cell division and plant energy metabolism. It influences the uptake of several various nutrients (including N), tillering and initial growth of sugarcane, in addition to improving juice quality for industrialization (Taiz et al, 2017;Garcia et al, 2018;Oliveira et al, 2018). In the plant-cane cycle, the average P content for the three varieties was 1.33 g kg -1 (Table 2), which is considered inadequate according to Orlando Filho (1983), Malavolta et al (1997) and Raij (2011).…”

The diagnosis of plant nutritional status was a tool to improve crop fertilization and thus ensure better productivity. This study aimed to evaluate the nutritional status of three sugarcane varieties (RB92579, RB98710 and RB961552) in the plant-cane and first regrowth cycles in the sub-humid region of the state of Alagoas, located in the Northeast of Brazil. The experiment consisted of a randomized complete block design with five replicates. Plant nutritional status was determined by chemical analysis of leaf +3 at the maximum growth phase of the crop. There was a varietal effect for macronutrient and micronutrient contents in both crop cycles, but no variety stood out in regards to leaf contents. However, all three varieties were deficient in Cu and Mn.
