1918] FIELD CROPS. 35 



as compared with yields of 4,470 lbs. of dry matter and 867 lbs. of proteiu for 

 5 varieties of soy beans. 



Soy beans for Pennsylvania, C. F. Noll (Pennsylvania Sta. Rpt. 1915, pp. 

 47-S7, pis. 2). — The adaptation of soy beans to Pennsylvania conditions, the 

 uses of the crop, and the field practices and cultural methods employed in its 

 production both for grain and forage are discussed, and rotation and variety 

 tests noted. The advantages of soy beans over cowpeas in Pennsylvania are 

 briefly outlined. 



In variety tests conducted during 1913 and 1914, Ohio 7496, Medium Green, 

 and Ohio 9016 were deemed the three leading varieties for hay production, -with 

 average yields of 5,439, 4,694, and 4,540 lbs. per acre, respectively. Wilson, 

 Chestnut, and Ohio 10015, with average yields of grain amounting to 13.9, 13.7, 

 and 13.7 bu. per acre, respectively, were the leading varieties for grain pro- 

 duction. 



Another Stizolobium from, the Philippine Islands, F. A. Coffman (PhUip- 

 pine Agr. Rev. [English Ed.], 9 {1916), No. 4, pp. 282-287, pis. 4).— The author 

 reports observations on hybrid and spotted Stizolobiums grown in comparison 

 with the Lyon bean (S. niveum) in cultural tests at the Singalong experiment 

 station. The hybrid is thought to be the result of a cross between S. niveum 

 and S. deeringianum, while the spotted bean closely resembles S. pachyloHum, 

 as described by Piper and Tracy (E. S. R., 23, p. 338) and Sahr (E. S. R., 30, 

 p. 828). The tests are being continued at the Singalong and La Carlota 

 stations. 



The spotted bean is deemed superior to either the hybrid or the Lyon, while 

 the hybrid has proved superior in many ways to the Lyon. The tests now in 

 progress confirm these observations and in addition indicate that the spotted and 

 hybrid beans possess a decided resistance to a fungus disease, apparently a rust, 

 to which the Lyon seems to be peculiarly susceptible. 



The results of observations to date indicate that the hybrid and spotted 

 beans are new types of Stizolobium. The former may prove to be a so-called 

 " fixed hybrid " and the latter may be a mutant, although further observations 

 of these types in comparison with the original types are deemed necessary to 

 establish this point definitely. 



The author suggests that the spotted bean may have an origin similar to that 

 of the Georgia velvent bean, as described by Belling (E. S. R., 33, p. 533), 

 having lost the factor for late maturity, and also that for producing large 

 clusters of pods. 8. pachylobium is described as producing from 30 to 50 pods 

 per cluster, while this spotted type has never been observed to produce over 

 15 pods per cluster. A detailed description is given of the spotted bean. Due 

 to the fact that this type produces numerous root nodules, makes a large initial 

 growth of vine, blossoms early, matures seed sooner and more evenly than the 

 Lyon bean and apparently earlier than the Florida velvet bean, does not shat- 

 ter its seed, and possesses no stinging hairs on the pods, it is thought that it 

 may prove valuable as a cover crop for the southern United States. If it matures 

 within five months, as is the case in the Philippines, it can probably be grown 

 considerably farther north than many of the other Stizolobiums. 



Sweet clover: Harvesting' and thrashing the seed crop, H. S. Coe (V. S. 

 Dept. Agr., Farmers' Bui. 8S6 (1917), pp. 23, figg. i5).— Detailed directions are 

 given for harvesting and thrashing the seed crop of sweet clover, with special 

 reference to harvesting machinery. 



It is recommended as a general practice to utilize the second crop of the 

 second season for seed, the time of harvesting depending largely on the machin- 

 ery used.
