FIELD CROPS. 1035 



Wheat {Kentucky Sta. B%il. 89,pj>. 177-198, pis. 4).— Thi.s bulletin 

 i.s a report on variety and fertilizer tests with wheat. Similar work 

 has been previously reported (E. S. R., 11, p. TBI). Thirty-six vari- 

 eties of wheat were grown in 1900. The yields of grain and straw per 

 acre are tabulated for each A^ariety. The botanical description of the 

 varieties, with field notes on the same, and illustrations of 30 varieties, 

 are given. Fultz wheat gave the largest vield, 52.2 bu. per acre; fol- 

 lowed by Harvest King, 50.3 bu.; Lancaster Red, ■±9,9 bu.; White- 

 seeded (Tolden Cross, 49.7 bu.; and Harvest Queen, -19.5 bu. Kansas 

 Mortgage Lifter and Turkish Red produced the heaviest gi'ain, the 

 bushel weighing 05 lbs. The fertilizer experiments were conducted 

 on a farm in the region of the Coal-Measures formation. The results 

 indicated the need of phosphoric acid and hunuis in the soil. 



Experiments -with -winter -wheat, A. M. Soule and P. O. Van- 

 ATTER {Tennessee Sta. Bui., Vol. XIII, No. 2,p2)- 'iik, pi. l,figs. o). — 

 These experiments included fertilizer and variety tests, intertillage 

 experiments, and trials of different rates of seeding, and seed selection. 

 The work and its results are discussed at some length and the yields 

 obtained are given in tabular form. The results on small plats were 

 relatively correct as compared with field trials. Early and thorough 

 preparation of wheat land is recommended. Fulcaster wheat, with a 

 yield of -11.66 bu. per acre, was the most productive variety, followed 

 by Early Genesee Giant, with -11.35 bu. Improved Fulcaster. Niger, 

 Fultz, and Poole averaged over ±0 bu. per acre. Velvet Chaff pro- 

 duced the heaviest grain, the measured bushel weighing 61|^ lbs., and 

 Fultz, Poole, Harvest King, and Deitz Amber all weighed 60 lbs. or 

 over, although yielding more than 39 bu. per acre. The best milling 

 wheats were Fulcaster, Niger, Mediterranean, Improved Fulcaster, 

 and Deitz Amber, while White Golden Cross, Early Genesee Giant, 

 and Fultz were considered the poorest. Egyptian produced the weak- 

 est straw and Early Genesee Giant the stiffest. 



Among 22 fertilizer combinations tested in this connection, 10 tons 

 of barnyard manure produced the best results, increasing the yield 

 11.72 bu. as compared with wheat grown without a fertilizer applica- 

 tion. Five tons of barnyard manure per acre increased the yield 7.71 

 bu., at a cost of 26 cts. per bushel. A home-mixed fertilizer used at 

 the rate of 50 ll)s. of nitrate of soda, 10<> lt)s. of Tennessee acid phos- 

 phate, and 25 lbs. of muriate of potash increased the yield 8.07 bu., at 

 a cost of 27 cts. per bushel. 



In discussing the cowpea as a source of nitrogen in soil renovation, 

 the authors state that "nitrogen is chiefly stored in the leaves of the 

 cowpea plant and not in the nodules on the roots, as many suppose." 



Other results obtained indicated the best time for seeding wheat to 

 be from October 1 to 15. The intertillage experiments consisted in 

 cultivating, with a Breed's weeder, wheat grown in rows wide apart or
