Oat research to lift options for low rainfall areas.. Oats make up about one per cent of land use in Western Australia's eastern wheatbelt.. "There is growing interest in expanding oat production in these lower-rainfall areas to diversify rotations and help manage seasonal rainfall variation, declining grain prices, higher input costs, frost risk in susceptible paddocks and increasing weed burdens," he says...

Sow the following wheat crop directly over the row of the previous year's break crop... "Crop rotation reduces the incidence and severity of crown rot, resulting in yield gains of 17-23pc over continuous wheat," Dr Verrell said... "By following these two rules it ensures four years occur between wheat crops being sown in the same row space and reduces the incidence of crown rot in wheat crops," Dr Verrell said...

" Facilitating increased on-farm adoption of broadleaf species in crop sequences to improve grain production and profitability.. The area sown to pulse legume crops or canola has dramatically declined in the past 8-10 years, and despite 65-70% of southern grain region still growing pastures in rotation with crops, many of these pastures tend to have low legume contents and provide little nitrogen benefit to following crops... There are many good reasons why growers have reduced the frequency of use of broadleaf species in recent years related to late starts to the growing season, drought and risk aversion...

Table 1 shows that when planting between October and the 1 st of January, there is an 80% chance of receiving at least 107-126 mm of in-crop rainfall this calculation does not consider the impact of rainfall timing on crop demand... I have used 100 mm as an average loss figure for a summer crop in this region... Figure 4 supports the back of the envelope calculation suggesting the 180mm of starting water is the minimum required to achieve a 3t yield 6 to 8 years in 10...

Soybean rescues sugarcane from degraded soils.. Condong, NSW, soybean grower Mark North spoke at the Summer Grains Conference... Mr North said the decision to produce soybean as a summer crop grew out of an Industry and Investment NSW program derived from the 'Sugar Yield Decline Joint Venture' involving Queensland Primary Industries and Fisheries, BSES Sugarcane, Biological Crop Protection and the Sugar Research and Development Corporation...

keY points a break crop is any crop sown to provide diversity to help reduce disease, weed and pest levels in a paddock... the decision to grow a break crop is also complicated by many interactions through the cropping sequences including disease and herbicide carryovers and economic issues such as capital investment for new equipment or storage... pulses and oilseeds can be damaged in a flight auger, and alternative designs including belt shifters are preferred...

A match made in canola heaven.. "Over a decade of experiments, our team demonstrated the rotational benefit of canola, and growers saw that while it could be expensive and tricky to grow, it was profitable if you took a two-year view," he says... To help growers manage risk in canola in dry years, Dr Kirkegaard developed a simple yield calculator based on rainfall to determine a particular crop's yield potential so inputs were not wasted...

Canola tops break-crop gains.. Canola plantings have continued to increase in Western Australia and local researchers are working collaboratively to fine-tune tactics to help optimise profits from canola and other break crops across the grain belt... CSIRO senior research scientist Dr Roger Lawes says modelling shows that adding a break crop such as canola to continuous cereal rotations can be worth an extra 0.5t/ha of wheat following the break phase...

Northampton grain grower Karl Suckling (left) and Planfarm consultant Richard Quinlan inspect canola crops for Sclerotinia stem rot in August this year... Mr Quinlan says the research showed canola susceptibility to Sclerotinia increased on: loam and clay soils that held moisture longer, compared with sandy soils; shorter-season varieties that flowered earlier when the disease was sporulating; paddocks where there had been reasonable disease levels in previous years; and crops that were early sown - leading to high crop biomass early in the season... He says remotely sensed data from satellite, drones or real-time normalised difference vegetation index (NDVI) sensors might allow growers to measure crop biomass and vary fungicidal applications ...
