Field bean (Vicia faba L.) yield and quality depending on some agrotechnical aspects
MetadataShow full item record
Despite growing interest about field beans ( Vicia faba L.), only few researches have been carried out in Baltic countries on the possibility to increase field be ans’ yield and quality depending on different agrotechnical measures. Field trial was carried out in 2015, 2016 and 2017. Researched factors during all years were: A – variety (’Laura’, ’Boxer’, ’Isabell’), B – seeding rate (30, 40 and 50 germinate able se eds m - 2 ), C – treatment with fungicide (with and without application of fungicide). Beans’ yield (t ha - 1 ) and yield quality characteristics were detected in the trial. Temperature and moisture conditions were mostly suitable for high yield formation of fie ld beans in all three trial years. In all three trial years, field bean yield has been significantly affected by all factors. The highest yield ( p = 0.001) was provided by variety ‘Boxer’ in all years (6.10 – 7.74 t ha - 1 ). Thousand seed weight (TSW) was sign ificantly affected by variety and fungicide application. From agronomical point of view, crude protein level was not importantly affected by seeding rate changes or fungicide application. Volume weight was affected significantly by increased seeding rate o nly in 2016. Fungicide application also did not affect volume weight significantly during the whole trial period. Field bean yield increased by each year, but the main tendencies in all years were the same: higher yield and TSW was provided by variety ‘Box er’, but higher protein content and volume weight – by ‘Isabell’. Seeding rate increase gave positive impact on yield. Fungicide application affected field bean yield, but did not affect its quality significantly.
