Effect of Sulfur Fertilization on the N-S Ratio in Soybean Varieties
- G. Dev and
- S. Saggar
Changes in N-S ratios in 12 varieties of soybean (Glycine max L. Merrill) under varying levels of applied S were studied in a greenhouse experiment. Sulfur application lowered total N-total S ratios and widened protein N-protein S ratios. At the S level, where constancy in total N-total S ratios was obtained, one part of S was required for every 15 parts of N in protein for varieties ‘Hardee,’ ‘Clark,’ ‘Pb. soybean No. 1’; 12 to 14 parts of N for ‘Dare,’ ‘Hampton,’ ‘Hood,’ ‘Semmes,’ ‘Improved Pelican,’ and ‘Bragg;’ and 16 parts of N for ‘Hill,’ ‘Davis,’ and ‘Pickett 71.’Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
