FIELD CROPS. 829 



beans, 11 of Adsuki beaus, aud 2 of Seta beans, in addition to a considerable 

 number of cooperative tests. 



Field counts aud measurements indicated that suckering of corn depended 

 mainly upon the amount of plant food with which the main stalk was supplied. 

 A considerable loss resulted from the removal of suckers in case of plants 30 in. 

 apart in the row on rich land, but in case of plants 20 in. apart there was a 

 slight gain in combined value of grain and stover. Earlier results obtained 

 with planting at these distances have already been noted (E. S. R, 25, p. 232). 



In 5 years' variety tests Purple Straw has usually stood among the 31 best 

 wheat yielders. 



In the fertilizer tests " the 1910 results are in general accord with those of 

 former years for cotton [E. S. R, 25, p. 233], but are somewhat at variance 

 with previous results for corn." In the case of both corn and cotton, phos- 

 phoric acid and nitrogen apparently gave better results when combined with 

 potash. Two tons of stable manure per acre in combination with 160 lbs. of 

 phosphate yielded over 100 lbs. more lint per acre than did 204 lbs. of phos- 

 phate rocli in combination with 144 lbs. of dried blood. Peruvian guano alone 

 applied at the rate of 250 lbs. per acre apparently about doubled the yield of 

 cotton, while the use of 500 lbs. per acre produced more cotton by about one- 

 fifth than the application of 250 lbs. The use of 37 lbs. of kainit, 97 lbs. of 

 acid phosphate, 130 lbs. of nitrate of soda, and 110 lbs. of Peruvian guano was 

 followed by more than twice as great a yield of cotton per acre as was obtained 

 from the check plat. The use of 100 lbs. of sulphate of ammonia on June 27 

 apparently increased the corn yield by between 4 and 5 bu. of corn and 300 lbs. 

 of stover per acre. When 200 lbs. of either nitrate of soda or sulphate of 

 ammonia were applied to wheat in addition to 200 lbs. of acid phosphate and 

 25 lbs. of muriate of potash per acre, slightly better yields were secured than 

 when only the phosphorus and potash were added. 



In tests of solubilized organic nitrogen, potash manure, beet-refuse compound, 

 and calcium cyanamid, none of the newer fertilizers equaled nitrate of soda, 

 sulphate of ammonia, or dried bloocl in cotton lint production, but " in produc- 

 tion of shelled corn per acre beet-refuse compound, sulphate of ammonia, calcium 

 cyanamid, and potash manure gave better results than dried blood, solubilized 

 organic nitrogen, and nitrate of soda." 



In cooperative tests of 8 varieties of corn and 7 varieties of cotton, Sanders 

 Improved and Biggs Seven-ear consistently stood high among corn varieties, 

 while Toole Prolific and Cook Improved made a good showing among the cotton 

 varieties. 



The results of the third j-ear's work seemed to indicate that corn ears grown 

 from seed shelled from the middle of the ear had a decidedly higher shelling 

 jiercentage and produced more shelled corn, but less stover, than corn taken 

 from other parts of the ear. 



[Agricultural development of Nyasaland], J. S. J. McCall (Ann. Rpt. 

 Dept. Agr. Nyasaland, 1911, pp. 1-13). — The report shows a considerable increase 

 in the area of cotton cultivated under European management, the area in 1909-10 

 being 8,975 acres, in 1910-11 12,752 acres, and in the present season 23,314 

 acres. The average yield of lint per acre was 81 lbs. in 1909-10 and 103 lbs. 

 in 1910-11, some of the estates yielding as much as 200 lbs. per acre. The 

 British Cotton Growing Association has given considerable assistance to the 

 industry by providing seed for planting and guaranteeing to purchase the crop 

 at a fixed price. 



Other notes and statistics are given as to the area, yield, and value of corn, 

 rubber, tobacco, coffee, tea, beans, etc.
