Study of root length density of wheat under rainfed conditions, Bhairahawa, Nepal
1998
Sah, B.P.
An experiment was conducted to study the root length density (cm/cm3 soil) of wheat at varying depths under rainfed conditions in the rice-wheat system at the National Wheat Research Programme, Bhairahawa (NWRP), during the wheat growing season of 1995/96 and 1996/97. The depth of the water table ranged from 40 cm to 60 cm below the surface of the ground from sowing to harvest. A compaction layer was found between 15 cm and 25 cm below the surface under normal tillage conditions, which decreases downward root development and the capillary movement of water. Breaking the compaction layer increased root length density.
