Plot 8. Nitrate of potash. 



Plot 9. Same mixture of guano and potash. The plot was irrigated 

 only half as many times as the others, but the soil was culti- 

 vated after each irrigation. 



Plot 10. No fertilizer. 



Plot 11, Peruvian guano and bagasse ashes. 



Plot 12. Same as 11. Reserved for stripping cane. 



Plot 13. Peruvian guano and bagasse ashes. Cane kept clean of borers. 



Plot 14. Peruvian guano, bagasse ashes and a little nitrate of potash. 



Plot 15. Same as 11. Reserved for two dressings of fertilizer. 



Plot 16. Inoculating experiment for cowpea and alfalfa. 



Plot 17. Same as 11 with a small dressing of the mixture of guano 

 and potash. Cane thinned out in the rows. 



Plot 18. Same as 17. Cane planted at twice the usual distance. 



Plot 12. Same as 17. Water run between the rows and not on the 

 cane in rows. 



Plot 20. Guano, bagasse ashes, and chloride of potash. 



The same kind of cane was grown on all plots, and the method of 

 irrigating was the same except for Plots 9 and 19. The Peruvian 

 guano used contained 8$ nitrogen and 10^ total phosphoric acid. 



While the results will not be known until several months later, 

 the experiments have already brought out some interesting points. 



Plot 9 which has been irrigated only half as many times as the 

 other plots, was cultivated after each irrigation; the cane on this plot 

 looks as thrifty as the best and much better than some. The question 

 of conserving moisture by cultivation is of special interest for Peru 

 and further investigation in this particular might be advisable. 



Of the fertilizer test experiments, Plot 1 presents the best ap- 

 pearance. Plots 20, 5, 6, 18, 14 are very good. Plots 13, 19, 8,are good. 

 Plots 7, 2, 3, 4, 11, 12, 15, 17, are fair! Plot 10 is poorest of all. 



PLANTING TOPS OE STEMS. 



The question of the relative merits of tops and stems for seed-cane 

 has long been discussed. Experiences have differed and no universal 

 conclusion has been reached. The planting of tops is, however, the 

 more widely practiced. In Peru, tops are invariably used. 



Some experiments were tried to test the germinating power of the 

 buds from tops and from stems.
