1916] FIELD CROPS. 31 



Mangolds following wheat which had been treated at the rate of 2 tons of 

 magnesia per acre appeared to show a slight residual effect of this application. 



In a variety test of oats the Swedish variety Svalof Victory yielded 37.4 

 bu. and Banner, a Canadian variety, raidvod next with 34..5 bu. per acre. Among 

 four varieties of flax La Plata produced the highest yield of seed. The results 

 of a comparison of Pacey, Dutch, and Italian rye-grass were in favor of 

 Italian rye-grass in two years out of three. A grass mixture with ordinary 

 white clover gave a heavier yield of hay than the same mixture with wild 

 white clovei', but the wild white clover proved more promising for pasturage. 



A test of varieties of alfalfa resulted in favor of the Ilussian variety, the 

 Canadian ranking next, with Provence but slightly inferior. American (Ari- 

 zona) and Turkestan gave the lowest yield. 



In grass experiments the best results in improving old pasture were obtained 

 on a plat which had been limed at intervals, the last application having been 

 made in 1909, and which had received superphosphate and sulphate of potash 

 in 1913. Of different kinds of lime, magnesium lime proved the least effective. 

 Ground lime seemed to have given better residts than lump lime. 



[Field experiments at the Cuttack Experiment Station, 1914—15], G. Sher- 

 EARD {Rpt. Dcpt. xiyr. Biliar and Orism, 191^-15, pp. 4^-51). — Fertilizer and 

 variety tests with rice, and culture and seed selection experiments are briefly 

 described. 



The method of transplanting about two rice seedlings 9 or 10 in. apart com- 

 pared with the practice of transplanting eight or ten seedlings 5 or 6 in. apart 

 gave better yields of grain in each of three years, but the yield of straw was 

 generally in favor of the thicker planting. Experiments undertaken to deter- 

 mine the best rate for broatlcasting rice indicated that a saving of from about 

 18 to 36 lbs. of seed-rice per acre as compared with the general practice can be 

 made without reducing the yields. In the experiment reported, about 27 lbs. 

 of seed-rice per acre on well-prepared ground and omitting the after-plowing 

 gave higher yields of grain in every case than larger quantities of seed per acre 

 together with the customary after-plowing. 



In an experiment on the production of jute fiber and rice when grown in 

 rotation in the same year with about IG.OOO lbs. of cow manure applied to the 

 jute, an average yield of 843 lbs. of jute fiber and 2,153 lbs. of rice grain and 

 3,027 lbs. of straw were secured on irrigated land during the four years 

 1912-1915, inclusive. 



[Field experiments], S. N. Sil (Rpt. Dept. Agr. Biliar and Orissa, 191^-15, 

 pp. 11-29). — The results of experiments conducted at the Sabour Agricultural 

 College during the year ending June 30, 1915, are reported. 



Among other results constant cultivation of fallow during hot weather as 

 compared with no cultivation and tlie use of about 8,000 lbs. barnyard manure 

 per acre gave increased yields of wheat in every test. 



Rice seedlings grown in moist seed beds proved more satisfactory than those 

 produced under dry seed-bed methods. Seedlings two months old when trans- 

 planted gave better results than younger or older seedlings. Spacing the plants 

 6 or 9 in. apart gave much better results than spacing either 12 or 18 in. Green 

 manuring of rice lands for three successive years also proved beneficial. An 

 experiment in which from 1 to 40 rice seedlings were planted per hole showed 

 that 1 or 2 selected and 4 or 6 unselected seedlings per hole appeared to be the 

 economic limit in transplanting. Root-pnming appeared to stimulate the 

 growth of rice seedlings. In a fertilizer test the use in alternate years of about 

 250 lbs. of bone meal per acre proved more effective than the use of about 

 415 lbs.
