• Variety choice has a large effect on yield in high yielding environments; plan the rotation so that the highest yielding variety can be grown. • Nuseed Diamond was the most consistently high yielding variety at both Wallendbeen (dryland) and Leeton (irrigated). • Nuseed Diamond grew similar biomass (by maturity) as that grown by slower hybrids b...

• Due to a combination of factors there is likely to be increased cereal plantings in 2020, once the opportunity arises. • Failed pastures with decent levels of grass development are potentially high-risk scenarios for cereal diseases in 2020 as grasses host many of the causal pathogens. • Unfortunately, prolonged dry conditions increase the risk o...

Paper presented at the GRDC Grains Research Update in Dubbo, Goondiwndi, Nyngan, Barellan and Lake Cargelligo on How does phenology influence yield responses in barley? Picking a winner in variable seasons, presented by Felicity Harris or David Burch or Darren Aisthorpe or Greg Brooke....

• Maximum nitrogen fixation (N2 fixation) will only occur if conditions favour rapid development of functional nodules and vigorous plant growth. • Soil pH was the primary factor limiting the yield and nitrogen (N) contribution of acid-sensitive pulse crops in 83% of commercial paddocks surveyed in central and southern New South Wales (NSW), Victor...

Take home messages • Adult European earwigs are present all year, but eggs and juvenile earwigs are only present from April to November. • European earwigs can cause significant damage to canola, lucerne, lupins and in some cases, lentils. • The potential for damage to emerging crop seedlings by adult European earwigs exists, although it is depende...
-
Take home messages • Grower engagement is essential to achieving changes in practice with pest management. • Think small when considering changes. Set specific goals, plan small steps and review what happened. • Better pest management outcomes are achieved through incremental improvements in the basics: knowledge of key pests, planning management s...

Take home messages • Canola has a deep root system that can penetrate soil faster (~2cm/day) and for longer than wheat. • Earlier sown, slower developing canola crops can access deep stored water to out-yield later sown varieties if subsoil water is available, AND the spring is dry. • Managing crop sequence and summer fallows to improve deep-stored...
-
Take home messages • Match optimal flowering period to growing environment to maximise grain yield potential. • One variety doesn’t fit all; there are no commercially available varieties that are broadly adapted across a wide range of sowing times or growing environments. • Optimising variety phenology and sowing time combinations achieves grain y...

Take home messages: Dry conditions severely limited grain yield for both chickpea and lentil in 2019.Results from 2018 and 2019 indicate that sowing around the mid-May period gave the varieties tested the best opportunity to avoid abiotic stresses and allows efficient conversion of biomass to grain yield. Earlier sowing resulted in greater biomass ...
