FIELD CROPS.

"Iii every instance the percentage of nitrogen-free extract is greater 

 in the hay raised on the sulphate of potash." Japanese "barnyard " 

 and Japanese "common" were found to be the best millets for seed 

 production. Among 17 varieties of millet Japanese white panicle and 

 Japanese barnyard millet produced the largest yields of hay. 



Miscellaneous crops (pp. 34-42). — A number of these are reported 

 upon. The flat pea, horse bean, and sachaliue were not found valuable 

 for that locality. Sorghum proved inferior to Indian corn as a fodder 

 crop. Several other new crops proved unsuccessful. Three new varie- 

 ties of field peas were tested, two rows 70 ft. long being grown of each. 

 The different varieties were harvested at the same stage of maturity. 

 The yields and composition are given in the following table: 



Yield and composition of field peas. 



The yields are given of several varieties of oats. 



Sulphate of iron as a fertilizer (pp. 42, 43). — Sulphate of iron was 

 applied at the rate of 80 lbs. per acre to 2 plats of green soy beans. 

 The difference in favor of the treated plats over the untreated plats 

 was at the rate of 525 lbs. per acre, the crop being cut green for the 

 silo. "It has been claimed by Griffiths 1 that the use of this salt favors 

 chlorophyll formation, and that it therefore causes a perceptibly deeper 

 shade of green in the leaves of the plants to which it is applied. No 

 difference could be detected during the season." 



Trial of hay caps (p. 45). — Three kinds of hay caps were used at the 

 station — Symmes paper board, oiled cotton, and cotton impregnated 

 with tannin. The author states that the Symmes cap is most readily 

 applied, and that the cloth caps impregnated with tannin are more 

 durable than those of oiled cotton. Clover which was cocked quite 

 green and stood for a time with frequent rains kept best under the 

 cloth caps. " The porosity of the former in such cases appears to be 

 an advantage." 



Forage crops, I. P. Eoberts and L. A. Clinton [New York Cor- 

 nell tita. Bui. 135, pp. 271-296). — Experiments with corn, oats and peas, 

 barley and peas, millets, and clovers as forage crops were made in 1895 

 and 1896. The cultivation of these crops is briefly stated, and the 

 results of experiments are given in tabular form. The table following 

 gives the results with different methods of seeding corn.
