Mapsfone Oats ; Further Experiences, 



M. F. Phipson, Fox Hill. 



MR. PHIPSON reports so wing 50 lbs. 

 of Mapstone Oats on 8th February, 

 1901, covering about eight-tenths of an acre, 

 inland which had been previously manured 

 and under a crop of potatoes. The forage 

 grew well w'th practically speaking no 

 rust, except in the last stage of ripening, 

 "when a little rust showed in places 

 upon the straw, but not sufficient to in 

 any way affect the seed. 



The oats were reaped about September, 

 and the ratoons which sprang up from the 

 stubble rusted considerably. 



The crop yielded about 2^ tons of good 

 sound forage, from which was thrashed 

 813 lbs of good heavy oatp. 



Mr. Phipson intends sowing his seed in 

 the first week of January next, as that 

 sowed in February last, although irrigated, 

 stood all through the winter. 



Mr. Phipson's oats were examined on 

 21st August by the Entomologist, and 

 Mr. Fuller reports that upon that date it 

 was only ty very careful searching that 

 any rust at all was discovered, and then 

 only an occasional streak upon widely 

 separated plants. The oats stood then 

 4 ft. 6 in. high, and were carrying the corn 

 well. Average plants were selected and 

 sent to the Department of Agriculture by 

 Mr. Phipson, and from these the follow- 

 ing notes were made :— 



Average stems to stool, 18-7. 



Average seeds per head, 30'i5 (varying 

 from 20 tolC). 



Straw, 3-20 to 4-20 in. in diameter at 

 base. 



Root system large, and fibres plentiful ; 

 over 124 main roots counted upon one 

 stool. 



David G. Sclanders, Glbnisla Post. 



Mr. G. Sclanders reports as follows : — 

 " 1 planted 50 lbs. of Mapstone seed in a 

 fairly rich piece of sandy soil on 6th 

 April, 1901, and reaped 560 lbs. on 28th 

 October, 1901. 



" There was a little rust in the straw, 

 but nothing of any consequence. I had 

 a strip of Cape forage planted alongside of 

 the Mapstone, which was very bad with 

 rust. 



"I believe the Mapstone oat to be equally 

 as good as the Algerian, which it very 

 much resembles, but the Mapstone ripens 

 about one week earlier, and my Algerian 

 oats also had a little rust." 



M. Sandison, Berg Vlei. 



Mr. Sandison reports having planted 

 50 lbs. upon about five-eighths of an acre 

 on 5th April, 1901. No manure was used, 

 and the crop was irrigated three times. 

 During the months of September and 

 October the oats grew out well, the straw 

 being tall but fine, and the head rather 

 light. The crop, was reaped upon 1st 

 November, and was considered a good 

 one without rust or smut. It yielded, 

 when thrashed, 1,200 lbs. of dressed seed 

 oats of good quality. 



H. Naudault*, Umlaas Road. 



Mr. Naudauld reports having planted 

 on 4th February, 1901, the oats growing 

 to 3 ft. in height, but without coi"n. It 

 was then cut down with the machine, and 

 came on agaUi splendidly, corning well. 

 The crop was reaped on 1st November, 

 and yielded, on thrashing, 440 lbs. of seed. 



Mr. Naudauld states that he planted 

 Cape oats by the side of the Mapstone,
