National Subterranean Clover Improvement Programme., P. G. H. Nichols

Experimental Summaries - Plant Research

The National Subterranean Clover Improvement Programme (NSCIP) aims to develop, by breeding and selection, better adapted and more productive low—oestrogen cultivars of subterranean clover for a range of environments in southern Australia. The programme is a collaborative one with the University of Western Australia and consists of two phases: (i) early generation selection, which involves selecting varieties satisfying primary selection criteria; and (ii) field evaluation of advanced lines, which is conducted by the Departments of Agriculture in each State and co—ordinated by the Plant Breeder.

The first phase is conducted at the University Field Station (UFS) and is continued until …

Experimental Summaries - Plant Research

Trial 90C49

Grass and broad leaved weed control in direct sown crops.

Location: Chapman Valley Research Station.

The low rate of sprayseed with diuron was not as effective on the grasses. It may indicate some antagonism within the mix as the same rate of sprayseed with metribuzin did not cause any drop in grass control. The addition of 2, 4-D amine may have boosted the mixes activity on capeweed as the sprayseed metribuzin mix was not very good on capeweed.

New Block Badgingarra Rs Late Time Of Seeding., J. W. Bowden, R. J. Lunt

Experimental Summaries - Plant Research

Trial 89BA33,

Location: Badgingarra

Based on a 1.5 t/ha potential yield, the strategic treatment was planned to be 120 kg urea/ha 4WAS. However, the crop was poorly established and so NH4NO3 was used in the hope of getting better tillering than would be possible with the slower release urea source. Gambling on equal dollars to urea for 2/3 N, but believe that twice as effective.

DAP was used to place nitrogen with the seed in case there was no rain of significance after seeding. This nitrogen (only 5 kg/ha) was probably lost with the rains of 20-28/7/89 (50 mm). Urea …
