Field beans (Vicia faba) are one of the most important legumes in the world. In Latvia, during last 10 years the sowing area of field beans has grown more than 20 times. It is important to carry out new studies about the possibility to increase field beans’ yield depending on different agrotechnical measures. Yield depends on components forming it. Field trial was carried out at the Research and Study Farm „Pēterlauki” in 2016. Researched factors were: A – variety (’Laura’, ’Boxer’, ’Isabell’), B – seeding rate (30, 40 and 50 germinable seeds mE-2), C – treatment with fungicide (with and without application of fungicide). Temperature and moisture conditions were suitable for high yield formation of field beans in 2016. Detected yield components were productive stems mE-2, pods per plant, seeds per plant and per pod. Productive stems were significantly affected by seeding rate (p is less than 0.001). Pods and seeds per plant were significantly affected by all three factors. Number of seeds per pod is a typical and relatively stable indicator for the variety, its value was significantly influenced by the variety used, and it increased when fungicide was used.
