Impact of tillage and plane of fertilizer application on root attributes and yield of winter wheat


Author(s): Amit Chandra, SK Guru, TC Thakur and Dibakar Mahanta

Abstract: Subsoil compaction occurs due to continuous use of Zero tillage (ZT) or reduced tillage (RT) impeding root proliferation and crop yield over time. In several cases, depth of fertilizer application can modify the distribution of roots in soil profile as well as yield of the crop. This study aimed at evaluation of the effect of deep tillage (DT) and conservation agriculture (CA) on root attributes and yield of winter wheat wherein the machines were modified to place fertilizers either below or in the plane of seeds, respectively. In all the tillage treatments we studied root volume, average root diameter, root length density (RLD), root biomass and specific root length up to a depth of 40 cm and vegetative growth parameters and yield of the crop.
Root volume, root length density (RLD), and root biomass were significantly higher under DT at 10-20 cm; 10-20 cm as well as 20-30 cm; and 30-40 cm respectively, when compared with either ZT or DT. ZT and DT were found to have comparable values for these parameters. Root diameter and specific root length was higher under ZT when compared with either RT or DT, however, the changes between the treatments were insignificant at all depths. The vegetative growth was significantly higher under DT than under ZT or RT, but the straw and grain yield were comparable between the treatments.
