Louisiana Stations, Bulletin No. 6 (Second Series), January, 1891 (pp. 43). 



Field experiments with sitgar cane, W. C. Stubbs, Ph. D. 

 (pp. 1(K)-14'J). — These were along tlie same lines as the experiments 

 witb sugar-cane reported in Bulletin No. 20 of the Louisiana Stations 

 (See Experiment Station Record, Vol. I, p. 03), and included investiga- 

 tions on pliysiological questions, varieties best adapted to Louisiana, 

 and manurial requirements. 



Weather report (pp. 102-100). — Tliis iucUidcs tabulated monthly sum- 

 maries of the temperature aiul rain-fall at the Louisiana Sugar Station 

 from March, 1880, to December, 1890, inclusive, and of the meteorologi- 

 cal observations made during 1890; brief notes on the weather of the 

 past 5 years; and a tabulated summary of the temperature and rain fall 

 by seasons for 5 years. In 1890 " the seasou was favorable throughout to 

 the growth of cane, and hence the large crop was harvested in a very 

 immature condition. l!^either the temperature nor rain-fall has been 

 excessive, hut well distributed throughout the season, extending well 

 into the fall. 



"Taking the table and the seasons, we find that a dry, warm winter, 

 followed by a moderately dry spring, and tins in time succeeded by 

 a hot, wet summer, are conditions favorable to maximum growth of 

 cane. It seems too, that a dry, cool autumn, beginning early in Sep- 

 tember, is necessary to produce a large sugar content. After the cane 

 is laid by, frequent showers of considerable intensity ajjpear highly 

 beneficial." 



Distance heticecn cane rows (pp. 107, 108). — Eibbon cane was planted 

 in rows from 3 to 8 feet apart. The yield of cane and the results of 

 analysis of the juice are given in a table. The results in 1890 agreed 

 with tiiose of previous years in favoring a distance between the rows 

 less than the common distance of 7 feet. "Any planter is safe iu 

 adopting 5- foot rows, and upon these the 2-horse cultivators can be 

 successfully used." 



Fart of the cane to plant (pp. 108, 109).— Selected stalks of ribbon cane 

 were cut into two and three parts, and the tops, middles, and butts were 

 planted separately. The results, stated iu a table, confirmed previous 

 observations iu indicating that the upper part is equal or supei'iorto 

 any other i)ortion of the cane for seed. 



Number of stalhs of cane to plant (p]). 109, 110).— From one to four 

 stalks of purple cane were planted in each of two series of experiments. 

 " In the first series the entire cane was idanted 'uncut,' and in the second 

 tlie eane was cut in lengths of from 12 to IS inches." The results 

 stated in a table, indicate, as heretofore, that " with good cane two 

 stalks are sufficient to insure 'the largest returns." The uncut stalks 

 gave a larger tonnage, and in every case but one a larger sugar content 

 than the pieces of cane.
