“…In this context, studies that evaluate the nutritional demand of sugarcane varieties are fundamental, since fertilization constitutes a significant part of the production costs of the sugarcane industry (Silva et al, 2017b), however, studies that identify nutrient requirements have not been carried out frequently, and the information available mostly refers to varieties that are no longer planted (Oliveira et al, 2010). The results of these studies have shown that cultivars may present variations in nutrient extraction (Oliveira et al, 2010;Calheiros et al, 2011).…”

Sugarcane produces a large amount of biomass, extracts and accumulates high amounts of nutrients. In the literature the nutritional requirements for most cultivated varieties in the past are found, however there is little information on the new varieties currently planted. The objective of this study was to evaluate the nutritional requirement of four sugarcane varieties, currently very planted, in the cycles of plant-cane, first and second ratoon. The study was installed in a Yellow Oxisol. The experimental design was a randomized block design, with five replications, and four treatments: RB867515, RB92579, SP813250 and VAT90212. During maturation of the cane, in the three evaluation cycles, the productivity of natural biomass and the nutritional requirement of macronutrients of the varieties were determined. It was evidenced that the cultivars of sugarcane are of high productive potential and resemble the accumulation of biomass, observing a yield of 158, 128 and 107 t ha-1 in the cycles of plant-cane, first and second ratoon. Regarding the nutritional requirement, the varieties did not differ among them and expressed the following order of need in the plant-cane K > N > Ca > Mg > S > P, in the first and second ratoon, the sequence observed was K > N > Ca > S > Mg > P.

“…The climate is tropical rainy with dry summers, according to Koppen classification. The average annual rainfall is 1,200 mm and the average temperature is 29 ºC (Silva et al, 2017a). The soil of the experimental area was classified as a Latossolo Amarelo (Embrapa, 2013).…”

“…The varieties were chosen because of their high yield and industrial quality (Silva, 2017a(Silva, , 2017b, in addition to the high representativeness. The sum of their cultivated areas was more than 50% of the area planted with sugarcane in the Northeast of Brazil, one year prior to the installation of the experiment.…”

“…Considering that the extraction of soil nutrients by sugarcane is high, adequate fertilizer management is essential for the crop to reach high yields. Furthermore, fertilization represents a significant percentage of the production costs of sugarcane agriculture, thus it must follow strict criteria for optimization to obtain higher yield at lower cost (Silva et al, 2017a).…”

“…These variations are due to the morphological and physiological characteristics of the varieties, associated with uptake kinetics, including the nutrient uptake rate, the Michaelis-Menten constant and the minimum concentration, below which no net influx occurs (Malavolta et al, 1997;Marshner, 2012). A variety is considered efficient when it has good capacity in absorbing nutrients and using them in the production of biomass (Silva et al, 2017a).…”

Sugarcane extracts and accumulates high amounts of soil nutrients, because it produces large amounts of biomass. Nutrient contents for varieties widely used in the past can be found in the literature, but there is little information on current cultivars. In view of these considerations, the study aimed to determine the nutrient concentration in the shoot biomass of sugarcane varieties in the first regrowth cycle. The study was conducted at a Latossolo Amarelo in Fazenda Jequiá, located in the state of Alagoas, Brazil. The experiment was a randomized block design with five replicates, consisting of four sugarcane varieties: SP813250, RB867515, RB92579 and VAT90212. At maturity of the first regrowth sugarcane, nitrogen (N), phosphorus (P), potassium (K), Ca (calcium), Mg (magnesium), S (sulfur), zinc (Zn), iron (Fe), copper (Cu), manganese (Mn) and Boron (B) contents were determined. Varietal differences were found in nutrient contents. However, no variety showed higher concentration for all the elements. The varieties showed the following order of macronutrient concentrations: K > N > Ca > Mg > S > P. The average values were 0.47, 0.08, 0.66, 0.15, 0.13 and 0.11 dag kg-1 of N, P, K, Ca, Mg and S, respectively. Concentrations of 9.9, 98.7, 29.2, 1.9 and 4.4 mg kg-1 of Zn, Fe, Mn, Cu and B were found for the micronutrients, respectively.
