Excerpt from book: THE PROBLEM OF WEEDS IN THE WEST. BY L. H. PAMMEL. Weediness is an 'indication of poor farming. It has been said by Souk one that the farmers of the east do not fear the Canadian Thistle or other agressive weeds because the better methods of tillage make the fields clean. The average yield, of corn in Iowa according to the latest statistics is 32.9 bushels per acre. This can by proper methods of cultivation be more than doubled. According to the Year Book of the United State Department of Agriculture for 1903, the yield of corn per acre in Iowa from 1894-1903 was asfollows: 1894, 15.0; 1895, 35.1; 1896, 39.0; 1891. 29; 1898. 35; 1899, 31; 1900, 38; 1901, 25; 1902, 32.0; 1903, 28. During this period most of the years the state of Maine had a greater yield per acre than Iowa. Iowa is in the corn belt and has a greater acreage than any other state in the Union. A part of the low yield is due to unfavorable seasons as in 1894. We have not, however, had a year since then which was in any way unfavorable for a good or fair crop of corn. The unfavorable crop returns then must be due to other causes, chief among these are the weedy fields. In the year 1908 the writer had estimates made of the yield of some typical corn fields in Iowa. It was found that good clean fields yielded 50 to 60 bushels pet acre while the weedy fields only between 25 and 30. An increase of 20,000,000 bushels in Iowa should be possible by better methods of cultivation. This would mean that the farmers could easily increase their wealth by $8,000,000, allowing a little extra expense for labor. The present day farming in the corn belt is an economic .waste. Most of the weeds are easily destroyed, like the Pigeon Grass (Setaria glaucd. Foxtail (Setaria viridis), Smartweed (PolygOnum pennsylvanicum and oth...
