Cultivation in Ohio

Primary Uses:	Fiber and green manure
Planting:	Inoculant type "EL" (Nitragin Co.) is appropriate to this and other species of Crotalaria
Seeding Rate:	McKee et al. (1946) recommended broadcasting at 20-40 lbs/acre, or seeding in wide (3.5 ft) rows at 5-7 lbs/acre.
Fertility:	No information found on this aspect. Since it is a legume, no N fertilizer is needed.
Insects:	When in flower Crotolaria harbors high densities of Lygus hesperus.
Diseases:	Damping-off caused by Rhizoctonia solani may be damaging during cool, wet weather in spring.
Harvest:	Crotalaria can be threshed when dry but is difficult before fully mature. Threshed seed must be dried artificially or spread thinly on shed floors to dry.
Comments:	According to McKee et al. (1946), species of crotalaria reported as poisonous to livestock include C. spectabilis, C. juncea, C. burkeana, C. dura, and C. sagittalis.
