Drainage was the key to a successful trial. In 2017, pre-irrigation alone provided sufficient moisture to grow the crop successfully. In 2017, the addition of spring irrigations did not translate to improved yield or grain quality. In 2017 there was low disease pressure. Irrigated lentils and chickpeas could be quite profitable, assuming that the 2...

The ICC has delivered several projects thanks to GRDC investment, and the results have given practical insight into irrigated cropping. Variety trials, irrigated chickpeas and lentils and canola agronomy trials are currently being funded by the ICC making membership, sponsorship and alternative funding so important....

Herbicide resistance in ryegrass, wild oats, brome and sowthistle has been confirmed in southern NSW and northern Victorian random weed surveys. • A multiple tactic approach is required to combat re...

The rhizobia strain in root nodules can now be identified by DNA test. A survey of 20 irrigated pastures in the NSW Murray Valley indicated an 80% failure rate of preinoculation. The main problem appears to be storing seed too long after preinoculating. ‘Old’ seed needs an additional inoculation treatment....

The season is delicately poised, no El Nino, but the prediction of a late one is forming. Plenty of random things need to happen before one could form. The Indian Ocean isn’t playing unfair like it often does before an El Nino forms. Stronger pressure needs to decrease, or the effect could be similar to either phenomena....

Surface drainage from conventional border-check bays on low infiltration soils is slow and causes non-uniform irrigations. Installing shallow surface drains on bay surfaces provides rapid surface drainage and more uniform irrigations better suited to precise irrigation scheduling. Modified bays require high standard surface drainage and reuse syste...
-
Consistent high yields can be achieved with quick draining surface irrigation systems. Individually draining bays into a field drain OR skip-watering should be considered if water is on bays for longer than 10 hours. This is a good option for bankless channels on flat terrain (<1:1000) which suffer from water backing up....

Accurate irrigation scheduling is important for maximising crop yield and water productivity. The use of soil moisture and evapotranspiration monitoring takes the guesswork out of irrigation scheduling and helps assess irrigation performance. Evapotranspiration data, both past and forecasted, is freely available. Agriculture Victoria provides evapo...

At current livestock prices, gross margin returns in excess of $2000/ha have been achieved with irrigated grain and grazed canola. A better understanding of the agronomy of winter canola and how it fits into the livestock program has been established and are critical to success. Further work needs to be undertaken on the issues which are currently ...
