Residue management and genotype effect on sunn hemp organic matter and nitrogen decomposition

Agronomy Journal, Volume 115, Issue 1, Page 261-272, January/February 2023., 2023
Abstract Sunn hemp (Crotalaria juncea L.) is a warm‐season legume often used as a cover crop; however, there is limited information about nutrient cycling of sunn hemp residue. The objective of this study was to evaluate the effect of sunn hemp genotype and residue management on plant characteristics, decomposition, and suppression of Fusarium, Pythium,

Tobacco Ringspot Virus Isolated from Crotalaria (Crotalaria spectabilis).

Japanese Journal of Phytopathology, 1968
Two causal viruses were isolated from crotalaria (Crotalaria spectabilis) showing yellow ringspot and mosaic symptoms. The first virus was identified with bean yellow mosaic virus. The virus was transmitted mechanically and also by Myzus persicae. The hosts of this virus were crotalaria, broad bean, bean, soybean and Chenopodium amaranticolor.
