Deep banded phosphorus effect on chickpea root growth locations
Aims

To study root development under a chickpea crop and quantify root growth due to the addition of P at a depth of 20 cm.

Key messages
  • Deep phosphorus (P) placement at a depth of 20 cm resulted in root proliferation in desi chickpeas at Terry Hie Hie.
  • Deep P applied in the plant line produced more vegetative biomass compared with deep P placed between alternate plant lines (66 cm spacing) four weeks after sowing.
