Dual-purpose crops delivering better pastures can-wheat plot graze.. The successful implementation of dual-purpose cereals into mixed farming operations is delivering benefits to agribusinesses beyond just the bottom line... Researchers are now quantifying the indirect benefits delivered to pastures of shifting stock onto early-season canola or wheat crops, as well as the implications for weed and disease controls, management flexibility and business risk minimisation...

Dr Bell says several studies have shown a response to magnesium and/or sodium supplement in sheep grazing forage wheat, but the response in cattle has previously received little validation... One paddock was supplemented with a mix of Causmag (MgO):Salt (NaCl) and cracked grain at an allowance of 140 grams/head/day... Dr Bell says growers should provide stock with a mixture of 1:1 Causmag (MgO):Salt (NaCl) at an allowance of 20 grams/head/day for sheep and 140g/head/day for cattle...

Matthew Gardner, NSW Department of Primary Industries (NSW DPI) research agronomist, Tamworth, NSW says growers should consider sowing cereals intended for grazing or dual purpose as early as practical up to early May to maximise opportunities to accumulate biomass for winter grazing... "Grazing cereals early will minimise impact on grain yield but reduce livestock production, whereas, grazing late will increase the risk of a more negative impact on grain yield but more than double dry matter available for grazing," Mr Gardner said... "If yield penalties from grazing are avoided then the gross margin obtained from a dual purpose system is greater than that obtained from grain only," Mr Gardner said...

Investigations of animal performance of sheep grazing dual-purpose wheat in southern found 2-fold variations in growth of lambs (daily gains between 0.5-1.0% of liveweight)... Overall, supplementation increased the beef production per hectare by 92 kg and increased returns by $246 at a cost of $22/ha (i.e. 6 c/hd/day)... Differences in the experiment were that stock did not consume the supplement as readily as in the previous experiment, growth rates were already extremely high, averaging 1.6 kg/hd/day in the unsupplemented treatment...

The project has shown that: grazing does not increase the spread of Wheat Streak Mosaic Virus (WSMV) in wheat crops... In summary, grazing at 67.3 dry sheep equivalents (DSE)/ha for 31 days or at 33.7 DSE/ha for 62 days significantly reduced canopy leaf area index but also resulted in significantly increased photosynthetic rates post-grazing in young, fully expanded leaves... In summary, results showed that the fraction of incident light intercepted by grazed crops was reduced to only 10-20% compared with 95% in ungrazed crop...

It has shown that the use of such crops can increase farm income and that grazing can have minimal effects of grain yield... Provided apical meristems are no more than 5-10 millimetres above the plant crown when grazing commences, CSIRO Plant Industry's results indicate that grazing appears to retard apical extension, so that the 'grazing off' of meristems is minimised... There is an urgent need for better understanding of the plant physiological processes underpinning the recovery of the crop from grazing, especially in relation to the dynamics of soil moisture available to the crop...

While Esperance growers met a dry start to the season, sowing conditions for growers in most grain-growing regions are reported to have been close to ideal... We were a little understocked last year so, as a result, we had a little too much cover and there were a lot of snails around... With Rob's semi-retired parents Frank and Prue they crop wheat, barley, canola, faba beans, poppies, triticale and lucerne hay, and grow canola, clover and ryegrass as seed crops...
