PECULIARITIES OF APPLICATION OF MICORIZE PREPARATIONS FOR THE GROWING OF SWEET PEPPER IN A GREENHOUSE
In order to study the effect of mycorrhizal preparations on the performance of sweet pepper in film greenhouse conditions, the experiment scheme included variants where the mycorrhizal preparations of the BTU Center were used, which treated the root system of sweet pepper seedlings before planting at a permanent place of vegetation. Seedlings were treated with the drugs Melanoriz and Mikofrend separately at a dose of 0.5 and 1.0 l per 1000 units. seedlings. Seedlings whose root system was not treated with mycorrhizal preparations served as control. Seedlings of Claudio sweet pepper and Nikita F1 hybrid were planted in the CIMET film greenhouse in the second decade of April. Treatment of plants with mycorrhizal preparations has a positive effect on both the plant and the growth processes of the root system. The formation of ectomycorrhiza is determined as a result of the use of Melanorizo or Mikofrend preparations. The root system itself, at the end of the vegetation of the plant, was obsessed with the mycelium of the fungus, which protected it from soil moisture and the development of rot, especially root. With the use of Melanorizo and Mikofrend dose of 1.0 l per 1000 units. seedlings during the cultivation of Nikita F1 hybrid start budding, flowering and fruiting were observed earlier 2 days from the control plants. A similar positive effect of the preparations was obtained during the cultivation of Claudio, regardless of the dose of the preparation. The difference in the beginning of these phases of seedling development was 3–5 days, and the use of drugs provided a longer growing season. From the use of Melanoriz dose of 0.5 l or Mikofrend dose of 1.0 l per 1000 units seedlings during the
cultivation of Claudio variety received the largest number of fruits, their total number increases by 33%. The weight of the sweet pepper fruit varies depending on the dose of the preparation and ranges from75 g to 190 g. For the use of Melanoriz with a dose of 0,5 or 1,0 l per 1000 units. seedlings, during cultivation of Nikita F1 hybrid or Claudio variety, the highest fruit weight index was 160–190 g (in the case of Nikita F1 hybrid) and 150–170 g (in the case of Claudio variety). The diameter of the fruit, from the use of mycorrhizal preparations varied within wide enough limits: from 4.5 cm to 7.0 cm: the highest values were characterized by plants of the Claudio variety for the use of Melanoriz with a dose of 0.5 l per 1000 units. seedlings or Mikofrend dose of 1.0 l per 1000 units seedlings. In these variants, the diameter of the fetus was 7.5 cm and 7.0 cm. With the use of mycorrhizal preparations Melanoriz or Mikofrend, the yield of bell peppers can increase to 2.5 kg / m2. The higher yields are characterized by the plants of the Nikita F1 hybrid, and the smaller one by the Coaudio variety. Use of Melanorize at a dose of 0.5 and 1.0 l per 1000 units seedlings provide in the yield increase to 2.2–2.5 kg / m2, which helps in obtaining profitability at the level of 98–101%.
