Vinogradov, D., Lupova, E., Khromtsev, D., & Vasileva, V. (2018). The influence of bio-stimulants on productivity of coriander in the non-chernozem zone of Russia. Bulgarian Journal of Agricultural Science, 24(6), 1078–1084
The article presents investigations about the possibility of coriander growing in the non-chernozem zone of Russia. Varieties Yantar and Alexeevsky 190 were objects of the experiments. Coriander varieties response to bio-stimulants Nagro, Agat-25K and Extrasol was determined. Coriander varieties Yantar and Alexeevsky 190 showed high response to the use of growth promoting and bacterial preparations. Preparation Nagro applied at concentration of 1 l/ha was most efficient. The yield of Alexeevsky 190 was on average 0.10-0.11 t/ha higher than that of Yantar. The increase of Yantar productivity when using bio-stimulants was on average 0.22 t/ha higher and that of Alexeevsky 190 was 0.23 t/ha higher than the control for 2013-2016.
