“…The K contents found in green and dry leaves of Brachiaria decumbens were in compliance with the adequate range (12-25 g kg -1 ) determined by Werner et al (1996), decreasing with increasing N ( Figure 7). The negative relationship between K contents in Brachiaria leaves and N fertilization rates was also verified by Ferragine (1998) and Batista & Monteiro (2010). This result can be explained by the dilution effect caused by the greater vegetative growth of the forage (Mengel & Kirby, 2001).…”

SUMMARYAmong the production factors, adequate fertilization is an important tool to raise the productivity of pastoral systems and consequently increase the share of Brazil in the supply chain of primary agricultural products at the global level. The objective of this study was to evaluate the interaction of nitrogen and sulfur fertilization in Brachiaria decumbens Stapf. The experiment in pots with Dystrophic Oxisol was evaluated in a completely randomized design with four replications in a 5 x 3 factorial arrangement, involving five N doses (0, 100, 200, 400, and 800 mg dm -3 ) in the form of ammonium nitrate and three S doses (0, 20 and 80 mg dm -3 ) in the form of calcium sulfate, with a total of 15 treatments. In the treatments with low S dose, calcium was provided as calcium chloride, to ensure a homogeneous Ca supply in all treatments. The results showed that the tiller production and dry weight of green leaves and of stems + sheaths and total dry weight were favored by the combination of N and S fertilizer, while the proportion of dry leaves was reduced. Nitrogen fertilization raised the N contents in green leaves and stems + sheaths and reduced K contents in fresh and dry leaves. The response to S rates in the N content of green leaves was quadratic.Index terms: fertilization, Brachiaria decumbens, plant nutrition, forage plants.(1) Received for publication on July 3, 2012 and approved on May 14, 2013.(2) Professor, Univ Estadual Paulista "Júlio de Mesquita Filho", UNESP/Campus de Dracena.

“…Batista & Monteiro (2008) showed the effects of S to enhance the response of marandu grass to N fertilization, with an increase in tiller and leaf number and total dry matter production. In turn, Batista & Monteiro (2010) reported a negative correlation between N and S fertilizer and K content in newly expanded brachiaria leaf blades.…”

“…In the same way, Francisco et al (2012) also did not find correlation between foliar nutritional status, N doses and inoculation with Azospirillum in corn. However, in a study carried out by Batista & Monteiro (2010), N fertilization positively affected the proportion of Ca and Mg and negatively the proportion of K in the shoots of marandu grass.…”

“…Regression analysis (Figure 2d) at R1 shows that the maximum level of Mg was 4.61 g kg -1 at 55 kg ha -1 N. After this point, Mg content decreased to 3.37 g kg -1 at 200 kg ha -1 N. Studying 'marandú grass', Batista & Monteiro (2010) found the highest Mg content of 3.4 g kg -1 in the shoots after the second cutting at 266 mg dm -3 N. In contrast, Costa et al (2008) studying N and P fertilization on 'xaraés grass', did not observe significant effects of N doses on Mg content in the shoots in all cuts.…”
