YIELD OF SPRING CAMELINA SATIVA (L.) GRANTZ VARIETIESAT DIFFERENT LEVELS OF MINERAL NUTRITION IN THE NON-CHERNOZEM ZONE
The article presents an analysis of research on improving the technology of spring Camelina sativa (L.) grantz cultivation in the southern part of the Non-chernozem zone of Russia. The research was carried out at the agrotechnological experimental station of «Agrotechnopark» (Ryazan State Agrotechnological University named after P.A. Kostychev) in the Ryazan district of the Ryazan region, on gray forest soils in 2019-2020. Established that vegetation period depended on the level of mineral nutrition. For Veles variety it was 65-74 days, for Jubilee variety - 63-71 days. Spring Camelina sativa (L.) grantz of the studied varieties was characterized as a precocious crop. Jubilee and Veles varieties responded well to the application of mineral fertilizers, primarily nitrogen. The maximum yield was obtained on the N120P100K100 variant (14.0 C/ha for Veles; 13.3 C/ha for jubilee). Varieties of spring Camelina sativa (L.) grantz matured together, easily threshed. Harvesting was carried out directly, without desiccation.
