The variables related to the agro-industrial quality in sugarcane considered as main tools are being used by producers to choose the varieties to be planted. In general, cultivars that present a ...better industrial yield for the manufacture of sugar and alcohol have great importance promoting crop sustainability. In this research, the objective was to evaluate the industrial quality of four sugarcane varieties during plant-cane, first and second ratoon crops. The experimental design was a randomized block, with four treatments and five replications. The varieties studied were RB867515, RB92579, SP813250 and VAT90212. In first and second ratoon cycles, the industrial quality of the four varieties was evaluated by determining the fiber content, apparent sucrose (Pol), purity, soluble solids (Brix) and total recoverable sugars (TRS). The results showed that varieties RB867515, RB92579, SP813250 and VAT90212 were similar for agro-industrial quality. In first ratoon crop, only fiber was same between varieties. The RB867515 evidenced larger soluble solids and recoverable sugars. In second ratoon crop, the RB92579 evidenced larger apparent sucrose (Pol) and soluble solids (Brix) and total recoverable sugars (TRS).

Sugarcane nutritional requirement knowledge has great importance for an adequate crop management, since allows the selection of efficient varieties in the use of nutrients, contributing to a better ...use of fertilizers and reduction of production costs. The aim of this study was to evaluate the stalks yield and the accumulation of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), zinc (Zn), copper (Cu) and manganese (Mn) of aerial biomass of four sugarcane varieties, RB867515, RB92579, SP813250 and VAT90212 during the plant-cane, first and second regrowth cycles. The experimental design was a randomized block with four treatments and five replicates. The cane was harvested due to maturity in the three crop cycles. The stalks yield and the nutrient accumulation of the aerial part of the varieties were evaluated. The stems yield presented were 126, 102 and 86 t ha-1 for plant-cane, first and second regrowth, respectively. Plant-cane macronutrients accumulation average presented the following decreasing order: K > N > Ca > Mg > S > P, for regrowth the observed sequence was K > N > Ca > S > Mg > P. The varieties presented high productive potential, and similar nutrients accumulation in the three cycles.
