Sorghum bicolor L - Opis:
- This study aimed to investigate the effect of alternate furrow irrigation accompanied by biochar application within different cropping patterns on soil respiration and root traits such as root dry weight and root volume associated with the dry matter yield of sorghum (Sorghum bicolor L.) over a twoyear period (2017 – 2018). The treatments consisted of three irrigation methods, which included every furrow irrigation, fixed furrow irrigation and alternate furrow irrigation and two cropping patterns including one-row, two-rows and three levels of biochar application including 0, 6 and 12 t ha-1. Different irrigation levels had a significant effect on root morphological indices, soil respiration, and the dry matter of forage yield. Biochar application showed a significant influence on soil respiration, as the highest soil respiration was observed in the B2 and B1 treatments (0.173 and 0.171 μmol C g-1 soil h-1, respectively), in contrast, the least was observed in the control treatment B0 (0.168 μmol C g-1 soil h-1). Biochar application had a positive effect on root dry weight, root volume and dry matter yield due to the prevention of severe moisture loss and further yield loss.
