Abstract
The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and the tissue that should be analyzed (upper leaf or shoot) is still questioned. Therefore, the objectives of our study were to: i) evaluate the stability of shoot and upper leaf N/S ratio with increasing shoot biomass (BM), ii) compare SC vs

dc.description.abstract | The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and the tissue that should be analyzed (upper leaf or shoot) is still questioned. Therefore, the objectives of our study were to: i) evaluate the stability of shoot and upper leaf N/S ratio with increasing shoot biomass (BM), ii) compare SC vs N/S in shoot or upper leaf as S prognosis tools, and iii) evaluate the use of SC simultaneously with grain N/S as a S diagnostic method in maize. Different S fertilization rates (0–32 kg S ha−1) were evaluated in nine field experiments where S and N concentration were determined in maize shoot, uppermost fully developed leaf, and grain samples. The main results of our study were: i) the N/S ratio in shoot and upper leaf was not stable with increasing BM; ii) the S prognosis capacity was similar when measuring SC or N/S on the shoot or upper leaf in vegetative growth stages, and iii) SC in grain allowed an adequate S diagnosis, which was not improved by including N/S in the prediction. In conclusion, based on its simplicity and reliability, we suggested the use of SC in the upper leaf at ≈V6 stage as a S prognosis tool (2.1 g kg−1 threshold). In addition, a 1.12 g S kg−1 threshold in grain was adequate for S diagnosis. | eng |
