Влияние факторов выращивания и длительности хранения на жизнеспособность зерна ячменя ярового
Abstract
An experiment was carried out during 2009-2013 with the aim to study the effect of different farming systems, soil tillage systems and storage duration on the viability dynamics of spring barley grains cultivated according to industrial (control), ecological and biological farming systems, using differentiated tillage (control), subsurface cultivation, moldboard-nonmoldboardand surface tillage. Grain samples were stored for 12 months in linen bags in an uncontrolled environment (in a warehouse). It was determined that viability values of barley grains increased during the storage in all the studied variants. In barley samples, which were cultivated according to industrial and ecological farming systems, after 6 and 9 months of storage, the viability indicators met the requirements of the standard for barley used for sowing and brewing purposes. No significant differences were noted in the change of the viability of barley grown according to different farming and soil tillage systems in the process of storage. However, the highest viability indicators were recorded by the barley grains cultivated according to the industrial farming system and differentiated and moldboard-nonmoldboard tillage systems. The barley cultivated according to the ecological farming system and differentiated andmoldboard-nonmoldboard tillage systems recorded slightly smaller viability valuese. The lowest indicators of viability were recorded by the barley grains cultivated according to the biological farming system and differentiated and moldboard-nonmoldboard tillage systems.
