Tei<t of eighteen varieties. — The calculated yield per acre, percent- 

 ages of corn and shelled corn, etc., are stated in tabular form. 



Fertilizers for corn. — To test the needs of the soil and the effects of 

 the important fertilizing ingredients in ditferent forms and amounts, 

 si^ecial phosphoric acid, potash, and nitrogen experiments were made 

 on the plan of those with sugar-cane described in Bulletin No. 20 of 

 the Sugar Experiment Station, and summarized above. The results 

 in 1888, were inconclusive, but the experiments will be continued. 



Experiments irith cotton (pp. 283-289). — The purpose of these was 

 to test varieties of cotton, considering yield of cotton seed and per- 

 centage of lint and the manurial requirements of cotton on the soil 

 of the experiments. The plans were similar to those of the experi- 

 ments with corn just described. Thirty-eight varieties were planted 

 and were growing finely, when they were destroyed by a storm A\\- 

 gust 10. Some results are given, however, both for the tests of vari- 

 eties and for those with fertilizers. The indications are that nitrogen 

 is especially needed on this soil for cotton, but further experiments 

 must be undertaken before definite concbisions can be reached. 



Experiment m 7'otation of crops. — Eight acres of land have been 

 accurately laid out for an exjjeriment with cotton, corn, oats, and 

 i:>eas, in rotation. Tavo acres are devoted to each crop, one acre being 

 fertilized yearly, the other unmanured. 



Formulas for fertilizers for com and cotton. — This Station sees no reason for 

 changing the formulas for corn and cotton piiblished heretofore in its bulletins, 

 and in reply to the numerous inquiries from planters and farmers will here 



repeat those f<ir cotton, found heretofore so efficacious : 



rounds. 



Cotton-seed meal 700 



Acid phosphate 1, 100 



Kainit 200 



Mix thoroughly and apjily in a shovel furrow before planting, taking care to 

 mix well with soil by running a bull-tongue through it after distribution. From 

 200 to 500 pounds per acre are quantities usually recommended. If cotton seed 

 is on hand, it may be profitaldy made into a compost with stable or lot manure 

 and acid phosphate in following proportions : 



Cotton seed bushels 100 



Manure do 100 



Acid phosphate ton 1 



For sandy land 1,000 pounds of kainit may be advantageously added. Mix 

 well this compost before use and ajiply from r>00 to 1,000 pounds per acre in 

 drill before planting. 



BULLETIN No. 22 (NORTH LOUISIANA STATION), JANUARY, 1889. 



Annual Repokt of the North Louisiana Experiment Station 

 (pp. 293-320).— This Station, established among the hills of North 

 Louisiana and intended primarily to benefit that section, receives 

 enthusiastic support from the farmers. One evidence of this is the 

 large attendance at the nKmthly meetings of a farmers' club held at 

 the Station, which has undertaken to build a large hall on the Station 

 grounds. The local railroad has helped this movement l)y running
