1159. Howard, A., avd G. L. C. Report of the Imperial Economic Botanist. Sci. Rept. 

 Agric. Res. Inst. Push 1918-19 : 46-67. PI. 5-6. 1919. — The report includes a summary of the 

 progress of investigations during the year under report, a program for 1919-20, and a list of 

 literature published. Improved wheats (Trilicum vulgarc) "Pusa 4" and "Pusa 12" have 

 produced yields of 3350 pounds and 3000 pounds respectively per acre, under good cultivation, 

 in contrast with the very low yields of ordinary Indian wheats under Indian methods of culti- 

 vation. These improved wheats are being sent to other countries for trial. Other work in- 

 cludes methods of culture and improvement of indigo (Indigo/era tinctoria); sun-drying of 

 vegetables; methods of packing fruit for shipment; pollination of Indian crop plants; and soil 

 drainage. Poor drainage in the Gangetic Plains during the monsoon interferes with proper 

 root development and promotes excessive denitrification. Actual crop production under 

 improved methods of cultivation indicate that with small expenditure of organic fertilizer 

 the fertility of alluvial soils may be maintained or improved. — Winfield Dudgeon.

1162. Hyde, W. C. Orchard cover-crop experiments on the Mountere Hills. New Zea- 

 land Jour. Agric. 19: 364-365. 1 fig. 1919. — This is the final report of a 4-year series of ex- 

 periments. Oats made a good growth and oats with partridge peas were particularly good. 

 Blue lupine was the best of the legumes and it made much the strongest growth on limed 

 area. — N. J . Giddings.

1164. Jordan, W. H., and G. W. Churchill. An experience in crop production. New 

 York Agric. Exp. Sta. [Geneva] Bull. 465. 20 p. 1919. — An account of an experiment in which 

 a 4-year rotation of crops (corn, oats, wheat, and hay) was carried through four rotations 

 on plats fertilized in different ways — with farm manure, a complete chemical fertilizer, a par- 

 tial chemical fertilizer, and no fertilizer. On some plats the hay crop was red clover; on 

 others, timothy. The total amount of dry matter produced w T as somewhat greater on plats 

 treated with farm manure than on plats receiving a complete chemical fertilizer; and about 

 56 per cent greater than on unfertilized plats. Especially noteworthy is the fact that crop 

 production was maintained as efficiently on the timothy plats as on clover plats. The results 

 of a series of soil analyses made in connection with the experiment show the unreliability of 

 soil analysis as a means of measuring soil fertility. — F. C. Stewart.

1166. Kellogg, James W. Seed report, 1918. Bull. Pennsylvania Dept. Agric. 2 3 : 1-29. 

 5 pi. 1919. — The bulletin includes a table giving standards of purity for various seeds; re- 

 sults of tests on special samples; average purity of official samples; results of inspection and 

 analyses in tabular form; and illustrations of the noxious weed seeds found in farm seeds. — 

 C. R. Orion. 



1167. Kellogg, James W. Seed report, 1920. Bull. Pennsylvania Dept. Agric. 3 4 : 1-28. 

 1920. — Standards of purity established by the Seed Law for 20 kinds of seeds are given; also 

 the results of special samples tesfed for purity; the average purity of official samples and the 

 results of inspection are discussed and the data arranged in tabular form. — C. R. Orton.
