ABBOTSFORD, SUMAS AND MATSQUI SNEWS fe Fre Oats Proven To Be The Best Annual Hay Crop, After Tests ~ Made At Experimental Farms _ Interesting data on cereal grain crops for annual pasture are given in the June umber of Scientific Agri- culture as a result of investigations by Dr. Kirk, Dominion Agrostologist, Ottawa; J. G. Davidson, assistant superintendent, Dominion Experi- -mental Farm, Indian Head, Sask, and S. N. Hamilton, Division of Chemistry, Ottawa. It is pointed out that annual pasture crops are im- Rudder Of Big Liner Cunard Vessel To Have Largest Of Its Kind Ever Built ‘i New problems of marine design face the builders of the Cunard super liner 534, which is under con- struction at Clydebank, Scotland, ac- cording to reports received by officials of the line in New York. The final stage in the manufacture of portant in many parts of Canada, and that, while the superiority of oats as the one best annual hay crop has been the ship's 150-ton rudder, the largest of its kind ever built, has been reach- ed and arrangements are being made throughout Canada, it is not so clear- ly appreciated that oats are also the best annual pasture crop. The data in A " supports the view that the oats crop’ is even more valuable for pasture than for hay as compared with other cereals. . There are certain questions relat- ing to the use of cereal grains for pasture that have not been investi- gated. Definite information is lack- a _ ing on the relative productivity and nutriment value of the different cereals. It is not known which of _ them,has the greatest power for re- growth after having been eaten off, _ and which of them will produce the greatest number of pasture crops in - a single season. Several other ques- tions also require answering. What is the best time to begin pasturing? _ How does the percentage of protein s) _ in the herbage compare at different stages of growth? Will the fresh _ young growth provide a high pro- _ tein feed as is the case with peren- nial grasses, and, if so, is the total seasonal yield of protein satisfac- | 5 tory? Are the results better with’ early than with late seeding, and | how do the different cereal crops _ compare in this respect? In order to amswér these ques- tions, an experiment was started in _ the spring of 1932 at the Dominion _ Experimental Farm, Indian Head,| Saskatchewan. Four cereals were. * grown, namely, oats, barley, wheat | and spring rye. These were cut _ with a horse mower to stimulate | grazing. Provision was made for a4 five plots of each cereal, clipping to begin at different stages of growth at (1) 3-leaf stage; (2) 5-leaf; (3) short blade, (4) early heading, (5) _ fully headed, and as often thereafter as the growth reached seven to eight A inches. These measurements refer to the leaf mass, and the following is the summary of the results ob- tained. Oats, barley, wheat and spring rye were compared with ref- erence to yield, feeding value, and utilization as annual pasture crops. _ With respect to yield of dry matter per acre and per centage of protein, oats were always superior to barley, é followed in order by wheat and spring rye. In total average yield of protein per.acre from the early seed- ing, oats exceeded barley by 54 per cent., wheat by 96 per cent., and| spring rye by 112 per cent. At the)
