ABSTRACT
The organic fertilization and ecological farming is getting more popular and required. In this article the studies of organic farming of hemp (Cannabis sativa L.) are presented. One of the options of organic fertilizer is the mulberry silkworm (Bombyx mori L.) breeding waste. This insect breeding is a cheap source waste which gives very positive results on the plants yield. In this research 3 repetition pots were tested: with silkworm fertilizer 15 t/ha, 30 t/ha and pots without fertilization (control). The total length, technical length, panicles length and diameter of hemp were measured. Moreover, the chemical composition of plants with and without fertilization was compared. The mean total length and technical length were highest in 15t/ha of manure dose. Whereas the panicles and the diameter of hemp were highest after 30 t/ha of manure dose.
