Experiments with sorghum, G. H. Failyee, and J. T. Willard 



{Kansas ^Sta. Bui. -iS, pp. 93-111). — This is a coiitiiiuatioii of work 

 reported in Bulletin 30 of the station (E. S. E,, 4, p. 721), and includes 

 analyses of varieties, improvement by seed selection, effect of ferti- 

 lizers, and influence of time of day upon the density of the juice. The 

 work of improving sorghum by selecting seeds from individual 

 stalks of special merit has been in progress for G years. The following 

 table, giving the sugar content of the juice, shows the great improve- 

 ment resulting from careful seed selection: 



Cane suf/ai' in sorghum juice during 6 gears. 



Selected seed from the best varieties will be distributed to farmers 

 of the State on payment of postage, 



"[The results of the fertilizer experiment] show that there is nothing to indifate 

 the advisability of applying fertilizers to sorghum grown upon such ground as this, 

 which is upland of moderate fertility. In several cases the yield per acre was 

 increased by the fertilizers, but lime and salt seem to be wholly bad in their effects, 

 reducing the yield of cane per acre and the percentage of sugar in the juice. . . . 

 When we consider the figures relating to the composition of the .juice, we find no 

 uniformity in the apparent effect of any fertilizer except lime, which has always 

 been injurious. Sodium nitrate (Chile saltpeter) has the best record on the average, 

 but during the last 2 years has evidently been of no benefit."
