Water use efficiency of marandu palisadegrass as affected by nitrogen and sulphur rates Rev. Ciênc. Agron.
Artur,Adriana Guirado; Garcez,Tiago Barreto; Monteiro,Francisco Antonio.
This study aimed to evaluate the effects of combination of nitrogen and sulphur fertilizations on water consumption and water use efficiency by marandu palisadegrass (Brachiaria brizantha cv. Marandu). The experiment was carried out in a greenhouse, using a Typic Quartzipsamment. Five nitrogen rates (0; 100; 200; 300 and 400 mg dm-3) were combined with five sulphur rates (0; 10; 20; 30 and 40 mg dm-3) in a fractionated 5² factorial, with four replications. The leaf area was harvested three times at intervals of approximately 30 days. Soil moisture was maintained at 70% of capacity retention through a self-irrigating system. There was an increase in consumption and water use efficiency by the forage grass due to the supply of nitrogen and sulphur. Nitrogen...
