summer weeds

Catalogue: GRDC Media
Research funded by the Grains Research and Development Corporation (GRDC) shows that early control of fallow weeds can lead to significant increases in the levels of stored plant-available water and increased availability of nutrients (especially nitrogen), benefiting crop yield and grain quality... Mr Cameron, who co-authored the GRDC's Summer Fallow Weed Management manual, said soil water saved by killing fallow weeds was often stored deep in the profile and its value is often far higher than that of in-crop rainfall... In the right soil, deep stored soil water can have a water use efficiency of up to 60 kilograms of grain/millimetre of stored water...

Early sowing of mid and longer maturing wheats can boost whole farm profits.. CSIRO Agriculture's Dr James Hunt says APSIM modeling indicates that - even with WA's Mediterranean climate - sowing opportunities in this State occur often enough so that adoption of longer maturing varieties for earlier planting has potential to increase whole farm wheat yields, particularly in medium and high rainfall zones... Dr Hunt says using a variety such as Whistler to bring sowing dates forward would allow growers to take advantage of early planting opportunities across a broad window from late March to early May and its stable flowering date would reduce frost risk...

CSIRO Agriculture's Dr James Hunt says APSIM modeling indicates that - even with WA's Mediterranean climate - sowing opportunities in this State occur often enough so that adoption of longer maturing varieties for earlier planting has potential to increase whole farm wheat yields, particularly in medium and high rainfall zones... The trials will be repeated this year and the aim is to assess whether long maturing varieties sown early in the year can yield as well as - or better than - short maturing varieties (such as Mace ) when these are sown in their optimal window in WA environments... Dr Hunt says using a variety such as Whistler to bring sowing dates forward would allow growers to take advantage of early planting opportunities across a broad window from late March to early May and its stable flowering date would reduce frost risk...

" Date: 18.01.2016 2016 starts with summer moisture management.. Until this year, Matthew cropped 95 per cent of his family's property and mated up to 1000 ewes, but he is selling the sheep so all resources can be focused on cropping and the implementation of an opportunistic fallow... While the sheep produced a reasonable return, Matthew says they compromised his crop agronomy and the money earned from the sheep did not warrant the time he needed to spend on them...

Not only do summer weeds rob growers of valuable soil moisture and nitrogen, recent research suggests it is also robbing growers of substantial profits through large yield losses... New South Wales Department of Primary Industries research and development agronomist Colin McMaster has led much of the research into the effects of summer weeds on plant available water and nitrogen in following crops and the yield benefit from controlling summer weeds... Temperature, moisture and organic carbon percentage are key drivers for nitrogen mineralisation a great opportunity for growers to build free nitrogen during the summer months when seasonal conditions allow...

Research has demonstrated the profitability of controlling summer weeds early, which increases soil water and nutrients available to the next season's crops, boosting their yields and grain quality... Mr Storrie has helped update Grains Research and Development Corporation (GRDC) resources that can guide growers on pre-harvest herbicide application to control weeds in winter crops, and post-harvest control of summer weeds... Mr Storrie said controlling germinating summer weeds in-crop, where possible, would give growers a head start on summer fallow management and lead to more water being retained in the soil, as well as extra nitrogen being available to crops in the next season...

Grain growers in the southern cropping region are advised to turn their attention to early control of summer weeds which rob valuable moisture and nutrients from soils into which next year's crops will be sown... Grains Research and Development Corporation (GRDC) Southern Regional Panel member and Swan Hill-based agronomist, Rob Sonogan, encourages growers to get on top of any summer weeds early to increase the effectiveness of weed management measures and prevent weeds from being a larger problem later... "Controlling summer weeds can assist growers in sowing their crops on time and can also minimise disease and insect issues that can occur when a 'green bridge' of weeds and volunteer cereals is allowed to survive over summer."..
