dc.description.abstract |
The poor reliability of chickpea yield produced in the marginal (<600�mm rainfall) areas of the northern cropping zone is a constraint to the wide adoption of the crop. Chickpea is a valuable rotation crop and is currently the only viable winter grain legume suitable to this region. This paper uses results from in-crop monitoring and crop simulation, to identify practical management strategies to improve the reliability of chickpea crops in this region. APSIM-Chickpea successfully simulated the commercial yields of chickpea crops monitored during the study. Soil water at sowing and sowing date were identified as key determinants of yield. A ?rule of thumb' was derived, which showed that crops sown with a starting plant-available water of ~100�mm at sowing had an 80% probability of producing a better than break-even yield for the majority of the region and this was independent of the soil's plant-available water capacity or crop sowing date. The probability of accumulating 100�mm of stored water in this western region is 90% following harvest of a May?sown wheat crop. Increased plant population improved crop yields in 60% of years, but this only translated to improved returns in ~50% of those years. The use of these simple management approaches will improve the reliability of chickpea production and ensure that these marginal areas have the option of a viable winter grain legume in their rotations. |
