EXPERIMENT STATION RECORD. 



Fertilizing ingredient ii reinared J'ruin llie soil by J acre of nine, and uned per ton of .rngar 



produced. 



The results of analyses of the mineral matter in the leaves, tops, and 

 dead cane of the different varieties are given in tables. From July, 

 1898, to Novem])er, 1899, inclusive, the crop received 26.99 in. of rain 

 and 76 in. of irrigation water. This increased the yield of sugar per 

 acre by 23,155 lbs. as compared with results on unirrigated plats. 

 Fertilizer tests in progress are briefly described. 



Wheat experiments, C. L. Newman {Arl'an.sa..^ tSta. Bui. 6'^, pp. 

 17-3Jt.^Ji<j. 1). — These experiuients embraced culture, rotation, seeding, 

 and variety tests with wheat. Plowing deeper than 8 in. did not prove 

 protitable. Disking and i-olling the soil thoroughly l)efore sowing and 

 thorough preparation of the soil in general diminished winterkilling 

 and the bad eflects of drought and increased the yield materially. 

 Sowing 5 and 6 pecks of seed per acre gave the best returns. Where 

 cowpeas, soy beans, and beggar weed Avere grown on light sandy soil 

 the yield of the following wheat crop was increased 56.5 per cent. 

 The returns indicate that crops for green manuring should not be 

 plowed under shortly before the crop is sown. This was shown by 

 the fact that where stubble of leguminous plants and the whole plants 

 were plowed under shortly ])efore sowing, the results were generally 

 in favor of the stubble. A crop of cowpeas grown after harvesting- 

 rye and potatoes increased the following wheat crop 30 per cent. 



"Wheat grown continuously on the same ground for three years and eacli crop 

 preceded by a crop of cowpeas gave an increased yield of 46. 7 per c-ent as conq^ared 

 with breaking the wheat stubble and not sowing cowpeas. Fertilizing cowpeas with 

 200 lbs. of acid phosphate and 100 lbs. of muriate of potash increased the yield of 

 wheat that followed 58 per cent. Wheat sown upon cowpea stubble, plowed under 

 and fertilized with 400 lbs. of a complete fertilizer, gave an average increased yield 

 of 64.4 and 78.5 jht cent increased yield the second year over soil treated only in 

 the usual way." 



Early Ripe, Indian Swamp, Purplestraw, Pool. Red May, Red 

 Wonder, and Tennessee Fultz gav(> the l)cst results.
