Hopi corn were planted on Jtily 29, at rates varying from three to 

 ten pounds of seed per acre. The results, recorded in Table 

 LXXVT, substantiate the popular opinion that thin seeding on dry 

 farms is the most profitable. 



TABLE LXXVI. 



CORN ; RATE OF SEEDING TEST, SULPHUR SPRING 

 V.XLLEY DRV-F.\RM, 1915 



Table LXXVI I records data obtained from a depth of planting 

 test in which six plots each of White Wonder and White Hopi corn 

 were .seeded on July 31, at depths varying from two and one-half to 

 seven and one-half inches. While White Wonder did not mature, 

 the indications from both varieties are that corn should be planted 

 deeply. The optimum depth, of course, depends upon the moisture 

 content of the soil, experience on the Sulphur Spring Valley Dry- 

 farm indicating that corn should be planted about two inches into 

 moist soil under the dry mulch. When corn is planted early, level 

 culture is preferred, but with later plantings, in the dry months of 

 May and June, listing is the better method. 



An experiment in the spacing of corn plants, somewhat similar 

 to that recorded in Table LXXVI, is noted in Table LXXVIIT.
