Effect of Restorative Measures of Fertility on Eroded Soils of Mountain Shirvan on the Winter Barley Performance

Due to the complexity of the relief of Mountain Shirvan, the dominant gray-brown soils, subject to varying degrees of erosion, have lost their fertility. To restore and maintain of these soil fertility, vermicompost and inorganic fertilizers were introduced under winter barley in various versions. It was revealed that the highest crop yield falls on the option of 6 tons of vermicompost per hectare. In this variant, the length of the ear of barley was 11.2 cm, the number of grains was 33, the weight of grains from 1 m2 was 183.6 g and the weight of 1000 grains was 44.7 g. 10–15% with the option of inorganic fertilizers. In this connection, the widespread use of vermicompost is considered expedient both from an economic and an ecological point of view.
