THE RELATIVE PERFORMANCE AND TARGETING RELIABILITY OF SUMMER CROPS (MAIZE & SUNFLOWERS) COMPARED TO GRAIN SORGHUM Take home message.. The objective of the experiments was to: determine the relative performance of maize and sunflower compared to sorghum evaluate if the performance could be made more reliable by using different hybrid maturities or by varying sowing time evaluate if there are alternative opportunities to include sunflower, sorghum and maize in the summer cropping window... At the Moree site a similar average pattern was measured with sunflower yielding 39% of the sorghum yie...

" Date: 09.02.2011 2010 Nutrition review - Following high yielding crops sparkee1.jpg.. A good program will look to at least maintain fertility and this goes closely with soil physical and biological health... Put tests strips in place, monitor paddock fertility and grain nutrient levels in the short and long term, and keep accurate records of the complete costs of strategies used and the data used to make the 2011 decisions...

The agreement, achieved through the NWI was based on a triple bottom line approach (balancing social, economic and environmental)... The MDBA must follow the process described in Division 1 of Part 2 in drawing the Basin Plan and setting the SDLs on a valley by valley basis... The MDBA are responsible for delivering the SDLs on a valley by valley basis, the States will have the responsibility of implementing resource plans which are basin compliant, meaning the States will have to determine where the cuts (if any) are made...

SCHEDULING AND OTHER TACTICS TO IMPROVE IRRIGATED WATER USE EFFICIENCY - A FOCUS ON CENTRE PIVOTS AND LATERAL MOVES.. The variation in water application increases rapidly with small decreases in CU. Figure 2 shows an example of a typical catch transect for a centre pivot with end gun showing the variation in the volume of water being applied along the machine... Current research is investigating automated control strategies using sensor input to effectively manage spatially and temporally varied irrigation applications under centre pivots and lateral moves in real-time...

A great proportion of the solutions to our problems are still herbicide based and in the future will lead to other herbicide resistance problems... Paddock screening trials done by DPI, at a known resistance site, showed poor efficacy from group B products but very good results from those products containing group H (Precept and Velocity )... Interim results from the survey work indicate that another two populations have similar tolerances to glyphosate as those discussed above...

In 2011, stubble biomass at each trial site was assessed by collecting stubble from one quadrat (50 cm by 50 cm) in each stubble type in each replication (prior to seeding)... Annual ryegrass was assessed from two quadrats (50 cm by 50 cm) per plot at Wongan Hills and six quadrats at Cunderdin... Use of the spreaders at harvest ensured that altering stubble height did not significantly impact stubble biomass...

Research has shown that sub soil constraints cost the northern region farmers millions of dollars per annum... Sub soil constraints are natural to our farming environment and are very difficult or expensive to manipulate... By including other layers of data such as remote sensing in crop and yield data it is possible to fine tune management of sub soil constraints to give a more profitable return from difficult soils...

Determining the yield deficit produced by a limiting growth factor, combined with the area of crop affected, allows accurate predictions on total economic losses to be made... Figure 2: Relationship between colour zone (grey and black bars indicate the corresponding hand sample results from the high and low crop vigour zones respectively), with (a) yield and (b) % pod maturity measured at each sample date... Table 4: Predicted total crop yield calculated from the area covered by each colour zone by the measured hand sample...

A comprehensive survey of no-till adoption amongst Australian grain growers has found between 70 and 90 percent of farmers use no-till practices on their farms, to some extent... The survey looks at what's driving the use of no-till and also examines why farmers in some districts have been slow to adopt no-till practices...

We have been conducting a series of trials to determine the ability of various pre-emergent herbicides to control brome... Trials have been conducted at various sites in SA and Victoria and on both species of brome... Brome was sprayed at 0 (T-0), 3 (T-3), 5 (T-5), 7 (T-7), 10 (T-10), 12 (T12) and 14 (T-14) days after sowing...
