Economic efficiency of cultivation of promising clonal rootstocks of stone fruit crops by the method of herbaceous cuttings

Vegetative reproduction of clonal rootstocks of stone fruit crops can be realized by various methods. For the final conclusion on the effectiveness of a particular method of propagating clone rootstocks, it is necessary to compare the costs with the results obtained, i.e. give an economic assessment of the method, which served as the basis for our research. The studies were carried out on the basis of a greenhouse complex with fogging installations of the base nursery of the research and production company Gardens of Chechnya. Studies have been conducted to evaluate the effective method of propagation of promising clonal rootstocks. The objects of research were the clone rootstocks VVA-1, L-2, Zarevo, and the VSL-2 stock was used as a standar. In the experience of grassy cuttings with a semilignified heel in the nursery garden, which is the main one in preparing the rootstocks before using for laying the first field of the nursery, comparing the economic efficiency of reproduction of new clonal rootstocks with the best standard VSL-2 rootstock showed that they are close in all the main indicators and quite cost-effective. In terms of economic efficiency of rooting of grassy cuttings, promising clonal rootstocks VVA-1, L-2 and Zarevo were only slightly inferior to the standard VSL-2 rootstock. The experience we conducted in comparison with the technology of growing seedlings of small-grain crops using unrooted and rooted cuttings in the conditions of the Chechen Republic showed that herbaceous cuttings with a semi-woody heel can be used in technologies involving laying the first field of the nursery rooted grass cuttings. This greatly reduces the cost of growing small-oriental-seedlings. Thus, promising clone stocks - VVA-1, L-2 and Zarevo can be effectively used in the conditions of the Russian south (including in the Chechen Republic) to produce high-quality planting material on a par with the standard clone stock of VSL-2.
