Studying The Effect Of Using Mikroo’stirgich Bioprepation Dates On Seed Germination And Development Periods Of Local Peanut Cultivars In The Conditions Of Uzbekistan
Abstract
This article provides data on the effects of application of biopreparations in the conditions
of typical sierozem soils of Tashkent region on seed germination and development of peanut varieties. The
analysis of data on seed germination revealed that the average germination rate in the control variety
"Kibray-4" was 95.9%, and in the variety "Leader" - 97.9%. Germination in the Lider variety was 2.0%
higher than in the Kibray-4 variety. In the laboratory, the germination of seeds of peanut varieties "Kibray4"
and "Lider" was 98.5% and 99.3%, respectively, in the variants using the biopreparation
"Mikroo’stirgich". It was noted that the variant used in the biopreparation "Mikroo’stirgich" has a positive
effect on the germination rate and germination rate of seeds. It was noted that the germination of seeds in
the "Lider" variety was 0.8% higher than in the "Kibray-4" variety. In the variants used in the
biopreparation "Mikroo’stirgich", the duration of the ripening period was reduced by 5-7 days compared
to the control variant, and the duration of the vegetation period was 141-137 days. A comparative analysis
of local peanut varieties revealed that the development period of Lider variety is 9-11 days longer than that
of Kibray-4.
