Influence of Seeding Rate on Common Vetch - Wheat Fodder Crop Mixture Performance Under Organic Management

Common vetch (Vicia sativa L.) originates from southern Europe and is also widespread in the Mediterranean region of Croatia. Due to the economic and ecological dimensions of growth, it is valuable to ascertain whether the application of seed inoculants or growth bio stimulators can enable ecological management of this crop in mixture with wheat (Triticum aestivum L.). Research was conducted through field experiment set up on agricultural area near city of Zadar, Dalmatia, during the vegetative seasons 2016/17 and 2017/18. The effect of different common vetch cv. Poppelsdorf sowing rates (40, 60, 80, 100 grains/m²) in mixture with wheat cv. Valerius (200 grains/m²), on fodder yield was evaluated through 3 treatments (control without fertilization, seed inoculation with strain Rhizobium leguminosarum bc Viciae 1001 and Bio- algeen growth bio stimulator application). The highest dry matter yield (DMY) determined on control was achieved in both years with 100 grains/m², 7, 98 t ha-1 in 2016/17 and 8, 82 t ha-1 in 2017/18, (P<0.05). The highest DMY determined with growth stimulator application was in both years significantly highest (P<0, 05) with 100 grains/m², 9, 24 t ha-1 in 2016/17 and 10, 29 t ha-1 in 2017/18, respectively. The DMY determined with Rhizobium leguminosarum bc Viciae 1001 seed inoculation treatment in both years was not significantly different between 80 and 100 grains/m², although those 2 higher rates had significantly higher yield (P<0, 05), compared to 2 lower seeding rates (40 and 60 grains/m²). The highest DMY and the biggest potential for ecological management in both years was shown by applying seed inoculation with Rhizobium leguminosarum bc Viciae 1001 (11, 34 t ha-1 in 2016/17 and 10, 71 t ha-1 in 2017/18).
