The use of the zoocompost for cultivation of the black soldier fly larva (Hermetia illucens) in raising cucumbers

In Russia, the amount of mineral and organic fertilizers used has been decreasing recently, which leads to a negative balance of the main plant nutrition elements in the soils of almost all agricultural regions of the country. In order to slow down the decline of macro- and microelements for plants in the soil, it is necessary to implement a set of measures for the systematic reproduction of soil fertility, which is directly related to the rational use of organic and mineral fertilizers. The proposed solution to this issue is possible based on the use of local nutritious organic compost. The zoocompost of the larvae of the Black soldier fly contains all the necessary nutrients (organic carbon, N, P, K, ash and trace elements). The experimental studies conducted in 2020-2021 on the use of zoocompost larvae of the Black soldier fly have shown that its use has a beneficial effect on the germination of plants and the number of fruits. Based on the results of a two-year study, it was revealed that zoocompost affected the number of fruit of cucumbers of the variety Dalnevostochny 27. It was found that 13-14 cucumbers were collected on the control sample, and when zoocompost was introduced, the number of cucumber fruit increased from 14 to 35 pcs. The average increase in fruit yield of 1 cucumber plant increases from 22.16 g in the control option to 420 g, the yield from the plot increased from 63.75 g to 692.68 g. It was experimentally established that zoocompost could be used as a fertilizer of organic origin, the optimal dose which was 1-2 tons/ha in spring application.
