Faba beans have a relatively small but significant fit in the central and north-west plains regions of NSW, being a valuable part of the whole farm system due to their rotational and logistical benefits... Faba beans provide an option to plant early (late March to late April) and harvest early (late September to mid October), which will broaden the windows of sowing and harvest... Being a high biomass crop with deeper root penetration, faba beans generally use more water than chickpeas and field peas leaving less residual PAW for the following wheat crop...

Sow the following wheat crop directly over the row of the previous years break crop and NOT between the old rows.. The results presented will focus solely on the mustard-wheat and chickpea-wheat systems and the last three years of the sequence trial (2010-2011-2012)... What the experiment has shown is that simply alternating row placement in consecutive years will not result in yield gains but a yield loss and increased CR (BO system)...

Millet can have a positive effect on following wheat yields, provided the millet crops are sown early in spring and terminated once 50 % cover is achieved... The results showed that if millet was sown early and removed early (40 days after sowing) there was a neutral or positive impact on wheat yield compared to a traditional fallow... The research shows that it is, differences in wheat yield when comparing the MF millet and CF traditional no-till fallows is significant and could be used to offset the costs of millet establishment...

NSW DPI pulse research agronomist Dr Eric Armstrong has been looking at the residual effects of having a pulse cropping phase in farming systems in southern NSW... Research from the New South Wales Department of Primary Industries (DPI) has found that in 2013 and 2014 brown manuring had no clear yield advantage in the following wheat crop over harvesting pulses for grain... "There was also strong evidence that manuring pulses compared with those harvested for grain leads to a further increase in grain protein of between 1 and 1.5 per cent, but this is unlikely to negate the opportunity cost of manuring the previous crop for yield and protein gains alone," he says...

A seed burial study at three burial depths was conducted to determine the seed persistence and emergence patterns of eight winter and summer weeds over a period of four years... Laboratory studies were also conducted to study the germination requirements and impacts of temperature by water potential, salts and pH on the germination of five key winter species in the region... Laboratory studies were conducted to determine the minimum, optimum, and maximum germination temperatures for five winter weeds including annual ryegrass, wild oats, barley grass, brome grass and wild radish...

The research that I will undertake in my PhD program aims to understand how legume break crops can mobilise P for the following wheat crop... We proposed that surplus mobilised P, resulting from the root activity of the companion break crop, would be scavenged and taken up by the inter-mingled wheat roots... The companion plants of chickpea, white lupins and field pea significantly increased P uptake by wheat (Figure 1) when the roots of both the wheat and the pulse were grown together, compared to when the wheat roots grew separated from those of the legume crop...

Nematode management critical to preserving wheat yields.. "The research found that growing one resistant crop, such as sorghum, maize or sunflower did not provide a quick fix in a field that started with damaging levels of 2500 P. thornei /kg soil... Populations of P. thornei increased after growing mungbean or soybean compared to sunflower, sorghum, maize or clean fallow and there were significant differences between the soybean and mungbean varieties...

Populations of P. thornei increased after growing mungbean or soybean compared to sunflower, sorghum, maize or clean fallow and there were significant differences between the soybean and mungbean varieties...
