FIELD CROPS. 



[Field crops at the Kabeti Experiment Farm, 1909-lOJ, J. Johnston 

 {Dept. Ayr. Brit. East Africa Ann. Rpt. 1909-10, pp. 119-l.'iS). — Meteorological 

 (luta for 1009 and. part of 1908 and 1910 are followed by numerous tables re- 

 porting the yields obtained in variety tests of numerous crops. 



In experiments with Rose Coco beans it was noted that the variety with 

 purple and black marked seed tended to suffer more from rust than the true 

 type with rose-colored seed. An itemized statement is given for the cost per 

 acre of maize groA\'Ti in British East Africa. 



In 2 year's tests of 8 different fertilizers and fertilizer mixtures for maize, 

 the highest yield followed the use of 100 lbs. of sulphate of ammonia, while the 

 application of 200 lbs. of kainit produced little observable effect. 



In a test of 12 different fertilizers and fertilizer mixtures for wheat, the 

 highest yield followed the application of 200 lbs. of superphosphate, this yield 

 l)eing even greater than that which followed the application of 400 lbs. of super- 

 phosphate. Similarly the use of 200 lbs. of basic slag was followed by higher 

 yields fhaii the use of 400 lbs. of the same miiteri;il. 



Annual report of the Lyallpur Agricultural Station for the kharif and 

 rabi seasons, 1909-10, S. Milligan and D. Milne {Ann. Rpt. Lyallpur Agr. 

 iSta., 1909-10, pp. 12+XL). — Although the use of soluble nitrogenous manures 

 gave an increased yield of cane, this was entirely counterbalanced by a reduced 

 percentage of raw sugar. 



Ridge and flat plantings of cotton were followed by yields of 7.2 and 6.28 

 maunds (about 501.8 and 515.19 lbs.) per acre respectively, while subsoiling and 

 ordinary deep plowing were followetl by approximately equal yields. A test of 

 the water recpiirements of American and l>esi cottons showed that the former 

 required 2 more waterings than the latter. 



Deep cultivation and subsoiling were followed by approximately equal yields 

 of wheat. A table states the results of a test of 20 varieties and strains of 

 wheat. Applications of 112, 168, and 184 lbs. of calcium nitrate per acre were 

 apparently followed by advances of 2f, 2, and 4* maunds respectively in yield 

 of wheat per acre, but the residual value of the application was not ascertained. 



Experimental work at Longerenong* Agricultural College, J. T. Pridham 

 (Jour. Dcpt. Agr. Yicluria, 9 {1911), No. 3, pp. 151-15.'), flys. 3). — A brief report 

 is given of the results of work with 4 generations of wheat resulting from 19 

 crosses which gave on the average a satisfactory i)ercentage of grain. A variety 

 test of oats is also reported. 



Emergency forage crops, D. A. Brodie ( U. 8. Dept. Agr., Office Sec. Circ. 36, 

 pp. 4). — This cii-cular was issued July 7 in view of the reports of drought from 

 the Central West. It gives directions for planting "quick growing crops that 

 may be used as substitutes for the i-egular hay and pasture crops." Citations 

 are given to other publications of this Department. 



Forage crops for the sand-hill section of Nebraska, H. N. Vinall ( U. S. 

 Dept. Agr., Bur. Plant Indus. Circ. 80, pp. 23, figs. 7). — Suggestions and direc- 

 tions are given for growing alfalfa, clovers, and grasses in the sand-hill section 

 of Nebraska, in view of the recent influx of settlers into this region. 



Results of the cooperative demonstration work in the dry farming dis- 

 tricts along the Santa Fe lines in New Mexico, J. D. Tinsley (Santa F6 Agr. 

 Bui. 1, 1910, pp. 31, figs. 7). — This is the first of a series of bulletins to report 

 the results of coopei'ative demonstration work conducted under the auspices of 

 the Santa F^ Railway Company. Notes are given on the soil and climatic con- 

 ditions of the region and on the crops. Samples of 32 varieties of corn were 

 distributed but very few good enrs were matured, although a few varieties
