Chickpea: Sourcing High Quality Seed (PDF, 521 kB).. When Ascochyta blight is found in a crop of Flipper, Yorker, Jimbour, Kyabra etc, a foliar application of a registered fungicide should be made immediately prior to the next likely rain event... Assess the risk of phytophthora root rot prior to planting, based on previous paddock history, and select a variety with some resistance (Yorker, PBA HatTrick, Flipper, Jimbour, Kyabra and Moti have useful resistance) if there is any likelihood of this disease...

In western Queensland, seasonal forecasts have moderate accuracy but rainfall from storms is very difficult to predict... New forecasting systems are based on general circulation models (GCMs), and Dr Stone's initial assessment has looked at the past six to seven years of forecasts... "Current weekly forecasts can completely change my thinking around operational decisions, such as for a winter crop whether we apply top-up fertiliser and whether we would try to harvest before a rainfall event...

Lateral move irrigator boosts WUE and increases yields.. "A great advantage I see is with cereals and canola, you can top-dress and then hit it with a 'rain' just to take that nitrogen into the soil and into the root zone," Terry said... "Often when top-dressing cereals and canola, you're looking for a rain event to take that in. During the irrigation season, we can water-run our nitrogen requirements through the syphons and it will distribute into the root zone...

At Dubbo, from June to November, 318 mm of rain fell on 52 days with 34 days >1.0mm, compared with a long-term average of 282 mm on 43 days (34 days >1.0mm)... Monitor the crops 2-3weeks after each rain event from emergence onwards and spray if Ascochyta is detected in the crop or is found in the district on any variety... (GMs also take into account other production costs estimated at $300/ha; chickpea price $450/t)..

For paddocks that had chickpeas in 2010, spray all varieties including PBA Boundary and PBA HatTrick , prior to the first rain event after crop emergence, three weeks after emergence, or at the three-branch stage of crop development, whichever occurs first... In paddocks that have not had chickpeas for at least two years, PBA Boundary , PBA HatTrick and most GenesisTM lines should not require their first Ascochyta spray until the disease is detected... Monitor the crops two to three weeks after each rain event from emergence onwards and spray if Ascochyta is detected in the crop or is found in the district on any variety...

Water logged soils can result in significant N loss through denitrification... Professor Grace says the first step in defining a nitrogen program is for growers to observe how their soils respond to rainfall to better understand how they are likely to lose nitrogen (see breakout box on types of N loss)... Previous work has shown that for every 1 kg of N lost as N 2 O, as much as 10-50 kg of N may be lost to N 2 ...
