Grain growers in 300-400mm Australian dryland farming systems lack a profitable oilseed broadleaf crop with stable yields that can be rotated with cereals (and field pea/chickpea)... Research is needed to address the comparative poor harvest index of B. juncea against canola ( Brassica napus) ... Suitable production zones have been successfully modelled using a median yield of 1.5t/ha (APSIM simulations), but model simulations should be redone for a long term median yield of 1.2t/ha...

Managing subsoil constraints - crop and varietal tolerance, rotations, fallow management, crop responses schwenke2_2.. Results from a species and varieties trial on an unconstrained soil in northwest NSW in 2004 (Table 2) also showed species differences in soil water use, but no differences between the varieties chosen for the study even though there were some differences in observed rooting depth and grain yields... Table 4: Species and variety responses at a constrained site in northwest NSW. Variety differences within a species are shown by the letter after the result; those with the same letter following were not significantly different...

KEYMESSAGES During the crop growing season, there was little difference in soil water under annual crop, perennial pasture, and pasture-cropped plots... In the paper, we concentrate on plots in which neutron moisture meter access tubes were installed... Deep drainage beyond a depth of 3.0 m was calculated from rainfall (measured on-site with a tipping-bucket rain gauge), ET 0(Allen et al. 1998) and change in soil moisture storage...
