Michael Robertson/Jacqui Hill 4th May 2004
The lablab module has received testing against four datasets from Queensland and the Northern Territory Cultivars currently simulated are: Highworth (annual) and Endurance (perennial) Users are invited to provide feedback on module performance to the convenors, Michael Robertson (Michael.Robertson@csiro.au ) and Jacqui Hill (Jacqueline.Hill@csiro.au).
Refer to the PLANT module science document for detail on the definition of parameters.
To sow the annual cultivar: if day = 24 and year = 2000 then lablab sow cultivar = highworth, plants = 5 (/m2), sowing_depth = 40 (mm) endif To sow the perennial cultivar: if day = 24 and year = 2000 then lablab sow cultivar = endurance, crop_class = small_leaf, plants = 5 (/m2), sowing_depth = 40 (mm) endif To kill the stems of the perennial cultivar over winter in order to stall progression into higher phenological states: if (mint < 5) and (lai < 0.5) and (day > 120 or day < 240) then lablab kill_stem endif
Figures below show module performance for both cultivars at Gatton in Qld over one season (sown 24 th Jan 2000) under irrigated and dryland conditions; cultivar Highworth at Katherine in NT over one season (sown 1 st April 1980) under irrigated and dryland conditions; cultivar Highworth at Brian Pastures Research Station near Gayndah in Qld over two seasons (sown 4 th Jan 2000 and 14 th Dec 2000) under dryland conditions.
