The effectiveness of the use of organic fertilizers Aminozol and Lebozol on the development and yield of winter garlic

The purpose of the work is to study the organic fertilizer Aminozol and fertilizer Lebozol-Complete care for the productivity and yield of winter garlic. The work was carried out on the collection site of the territory of the V.I. Edelstein Horticulture and Vegetable Growing Center, the K.A. Timiryazev Russian Agricultural Academy in 2021–2022. Varieties of winter garlic Odintsovo jubilee and Sagittarius were chosen as the object of research. The soil of the experimental site is sod-podzolic medium loamy, the thickness of the arable layer is 20–23 cm, the content of easily hydrolyzable nitrogen is 9.3 mg/100 g of soil, phosphorus is 15.0 mg, potassium is 8.3 mg, humus is 2.6%, pH is 6.8, which meets the needs of the crop. The repeatability of the experiment is threefold, the area of the accounting plot is 39 m2, the planting scheme is 60×6 cm, the density of standing is 278 thousand plants per 1 hectare. Experience options: 1) Odintsovskii yubileinyi (control); 2) Odintsovskii yubileinyi (double treatment with organic fertilizer Aminozol); 3) Odintsovskii yubileinyi (two-time treatment with Lebozol fertilizer-Full care); 4) Sagittarius (control); 5) Sagittarius (two-time treatment with Aminozol organic fertilizer), 6) Sagittarius (two-time treatment with Lebozol fertilizer-Full care). Before planting, the teeth were soaked in the preparation Maxim, to accelerate rooting and less disease incidence in winter. The planting was carried out in the first decade of October, as recommended for the conditions of the Moscow region. Agricultural equipment is standard for the cultivation of winter garlic. It was found that two-fold non-root treatment of garlic vegetating plants in the first growing season with organic fertilizer Aminozol contributes to an increase in yield in the Odintsovskii yubileinyi variety by 26.6% and in the Sagittarius variety by 17.8% in relation to control variants. Two-fold foliar treatment with Lebozol fertilizer-Complete care had a lesser effect on the increase in yield. The increase in relation to the control variants for the Odintsovskii yubileinyi variety was 13.3%, for the Sagittarius variety – 10.6%.
