Chickpea Trials: Optimum Plant Population for Surface Irrigation  (Finley) locations
Aims

To compare identical chickpeas plant population x cultivar trials under surface irrigation

Key messages

• Chickpeas sown under overhead irrigation gave yields of between 2.09 – 2.63 t/ha (cv Genesis 090) and 2.06 – 2.37 t/ha (cv PBA Royal), twice that of the identical trial sown under overhead.
• A grain yield of 2.4 t/ha was achieved with an established population of 19-21 plants/m2, this was significantly higher than the 2.07 t/ha achieved at 11 plants/m2 (average of both cultivars).
• Increasing the plant population up to 29 plants/m2 gave higher yields, although the advantage over 19-21 plants was not statistically significant.
• There were no significant differences in grain yield due to cultivar.
• No significant interactions were observed between plant population and cultivar on dry matter (DM) production at early flowering; Genesis 090 maximised DM production at 19 plants/m2 whilst PBA Royal maximised DM production at a lower plant population (29 plants/m2).
• Dry matter production at early flowering was maximised with an established population of 19-21 plants/m2(2.96 t/ha), this was significantly higher than the 1.72 t/ha achieved at 11 plants/m2.
• There were no significant differences in DM at harvest with an average of 8.73t/ha and a harvest index of 25.5% (data not shown).
• Harvest index was twice that observed in the identical trial sown under overhead irrigation (13 vs 25% HI).
