This analysis compares very favourably with that of ordinary 

 English hay, and shows a larger proportion of digestible and 

 nourishing material. In deeply worked rich soils at least three 

 crops may be obtained per annum when the plant is well 

 established. On the Richmond River (N.S.W.) Government Farm, 

 in one year, 14 tons per acre were obtained on the first cutting, 

 8 to 10 on the second, after which a third crop of 6 to 7 tons was 

 gathered— making a total yield of 28 to 31 tons per acre. 



An analysis of a sample of the crop grown on good cultivated 

 land on the creek flats of the Queensland Agricultural College, 

 and cut on April 22nd, 1901, compares rather unfavourably -^rith 

 the foregoing. The yield of grass in this crop was 10*525 tons 

 per acre, and of hay (air-dried grass), 2-858 tons per acre. The 

 analysis of the hav yielded the following figures (J. C. Brunnich,

There is a remarkable difference in nitrogen yield l)etw<MM 

 sample and that analysed by Mr. Guthrie. The uppareii 

 feriority of this crop is attributed by Mr. Brunnich to thf 

 that the grass was over-ripe when cut, and had btfti ixruw 

 exceptionally dry weather, and on a larger scale than ih«- 

 longbar sample. 



From the time that the first seeds in each spike are mat an 

 ripening of the whole spike occupies about three wteks. In 

 sequence, the harvesting of the seeds is a matter of some ditfic 

 Those collected during the first few days of ripening are of \: 

 quality than those shed later, for a much larger proportion of i 

 are mature, and will germinate. To produce a good pastur 

 well-prepared land, 5 to 8 lbs. of seed per acre is recommend, 

 being sufficient. The plant should be allowed to shed its
