Seed yield components and seed yield of winter vetch species (Vicia spp.) depending on row spacing

Abstract

The effects of row spacing (12,5 cm and 50 cm) on seed yield components and seed yield of winter-sown hairy, Hungarian and common vetches (V. villosa Roth, V. pannonica Crantz and V. sativa L.) were investigated in this paper. Number of plants per m2, number of stems per plant and per m2, crop height, plant length, lodging index, number of pods per plant, number of seeds per pod, 1,000 seed weight and seed yield were determined. Increased row spacing resulted in increased crop height by 13.6 %, decreased plant length by 8.5 %, increased lodging index by 22.3 %, increased number of stems per plant by 57.0 %, number of pods per plant by 43.5 %, number of seeds per pod by 14.7 %, 1,000 seed weight by 4.7 % and seed yield by 29.0 %. The highest and the lowest seed yields were obtained in Hungarian and hairy vetch, 1,380 kg ha-1 and 784 kg ha-1 respectively. .

Ispitivan je uticaj međurednog razmaka (12,5 cm i 50 cm) na komponente prinosa i prinos semena maljave, panonske i ozime forme obične grahorice (V. villosa Roth, V. pannonica Crantz i V. sativa L.). Analizirani su broj biljaka po jedinici površine, broj grana po biljci, broj grana po jedinici površine, visina useva, dužina biljaka, indeks poleganja, broj mahuna po biljci, broj semena po mahuni, masa 1000 semena i prinos semena. Veći međuredni razmak značajno je uticao na povećanje visine useva za 13,6 %, smanjenje dužine biljke za 8,5 % i na povećanje indeksa poleganja za 22,3 %. Širokoredom setvom povećan je broja grana po biljci za 57,0 %, broj mahuna po biljci za 43,5 %, broj semena po mahuni za 14,7 %, masa 1.000 semena za 4,7 % i prinos semena za 29,0 %. Najveći prinos semena ostvaren je kod panonske grahorice (1.380 kg ha-1), a najmanji kod maljave grahorice (784 kg ha-1).
