Aims
To value investigate the value of companion cropping systems of chickpea and cereals for improved crop and fallow water use efficiency.
Key messages
Combined yields of companion crops were equivalent to those of monoculture crops.
Companion cropping Wheat with Chickpea has provided more stubble cover.
