Response of chickpea to in-season application of nitrogen - Grass Patch locations
Aims

To determine if chickpea respond to applied nitrogen.

 

Key messages
  • Chickpea seed yield responded to 50 kg N/ha applied 8 weeks after sowing at Grass Patch in 2020
  • Higher rates did not increase yields when applied at 8 weeks after sowing or in a split application at 8 and 12 weeks after sowing.
  • Within plot variation resulted in no significant difference in the gross margin.
