Show Wheat Yield Boosted Through Fertilization Gains in Indiana Tests Exceed Seven Bushels Fertilizing wheat paid dividends 111 crop increases averaging seven to nine and one-half bushels per acre, Purdue university research men revealed in announcing results of 1947 studies conducted in 15 Indiana In-diana counties. Wheat yields increased seven bushels per acre when fertilizer HNHt applications averaged aver-aged from 150 to 200 pounds per acre. When the plant food treatment treat-ment was boosted to 300 to 400 pounds per acre, average production gains of nine and one - half bushels were obtained. ob-tained. Demonstrations with wheat started on various soil types last fall showed somewhat similar results, according ac-cording to the Purdue Pur-due research men. When 165 pounds of 0-12-12 was applied ap-plied on six southern south-ern Indiana upland soils, increases of five bushels per acre resulted. When the application applica-tion was doubled, yield increases averaged seven bushels per acre. "Applications of 300 to 350 pounds of 3-12-12 are being recommendedj for wheat on practically all upland silt or clay loam soils and for sandy loams," says a statement by the Purdue agronomy department. depart-ment. "If the 3-12-12 cannot be obtained, then 2-12-6 is a good substitute sub-stitute for the wheat crop itself. The additional potash in the 3-12-12, however, is especially important for the clover and corn crops following fol-lowing the small grain." |
