Crop-harrowing Experiment. 

 This was carried out at Deniliquin. Two plots of Federation were sown 

 under precisely similar conditions on 14th May, one of which was harrowed 

 on 1st August, the other being untouched. The yields were as follow : — 

 Crop harrowed ... ... ... 5 bus. 57 lb. 



Crop not harrowed ... ... 5 „ 36 „ 



Equivalent to an increase of 6 per cent. 



Graded v. Ungraded Seed. 



Tliese trials were located at Balldale and Lockhart, and uoth i-esulted 

 .-substantially in favour of graded seed. 



Acclimatized v. Unacclimatized Seed. 



At Deniliquin and Young plots of locally-grown Federation were included 

 to compare with that supplied by this Department, In both cases, however, 

 the local seed was from the 1918 plots. The figures are : — • 



Deniliquin. Young, 



bus. lb. bus. lb. 



local seed 6 6 10 24 



Introduced seed ... 5 57 9 48 



Experience indicates that better results are likely to follow the use of 

 acclimatized seed, other things being equal, especially in drier districts. 



Fallowing Experiments. 



These were carried out at Ungarie, and included fallowed versus non- 

 fallowed plots and also worked fallow versus unworked fallow. As the non- 

 fallowed plot was not available until late in the season, this section of the 

 experiment was seeded along with the late sown varieties, and was subjected 

 to particularly unfavoui-able conditions. The worked versus unworked fallow 

 plots were sown early. In any case the yields are only approximate, as 

 the whole of the fallowing experiment was more or less damaged by sheep 

 breaking through the fence. The yields were : — - 



Fallowed (sown 10th June, 1919) 2 bus. 12 lb. 



Non-fallowed „ ... 1 „ 40 ,, 



Worked fallow (sown 16th April, 1919) ... 4 „ 53 „ 

 Unworked fallow „ ... 3 „ 33 ,, 



Rate of Seeding, 



These experiments were loc^-ted at Ungarie and Balldale and were under 

 different conditions. 



The Ungarie plots were sown early (10th April), and in accordance with 

 past experience they showed a substantial margin in favour of the medium 

 rate of seeding. 



45 lb. of seed per acre ... ... 4 bus. 53 lb.
