The effect of sowing date and irrigation management on faba bean – Leeton 2021
• Sowing faba bean on 29 April (sowing date one – SD1) achieved a higher grain yield compared with sowing on 21 May (SD2).
• Irrigating faba bean with 2 spring irrigations on a border check layout increased grain yield when compared with rainfed.
• PBA Nasma was the highest yielding variety achieving 9.36 t/ha when averaged across both sowing dates and irrigation treatments.
PBA Nasma was the best performing variety, achieving the highest grain yield when averaged across sowing dates and irrigation treatments. PBA Nasma also had the largest seed with a hundred seed weight of 77.3 g, highest total biomass (17.88 t/ha) and largest harvest index (52.7%) when compared with the other 3 varieties.
Sowing date had a significant effect on grain yield, reducing by 1.48 t/ha, when sowing was delayed from 29 April to 21 May 2021. Both the 2020 and 2021 irrigated faba bean experiments demonstrated significant yield increases with a late April sowing time when compared with a mid May sowing time. Sowing in late April also had an increasing effect on biomass by 19% and hundred seed weight by 8%, in contrast harvest index reduced by 4%.
Applying 2 spring irrigations increased yield by over 24% to 9.51 t/ha, through increased biomass by 19.8%, harvest index by 2% and hundred seed weight by 4% when compared with the non-irrigated treatments.
