Effect of row spacing and seeding rate on seed and dry matter yield of red clover (Trifolium pratense L)

Abstract

A two-year study (2006 and 2007) was carried out to examine the effect of row spacing and seeding rate on seed and dry matter yield of red clover in a production system for mixed utilization. Field experiments were conducted at the field of Agricultural Highschool in Futog, Serbia. Red clover crop was established in three row distances: 12.5 cm, 25 cm and 50 cm, and three seeding rates: 2.5 kg ha-1, 5 kg ha-1 and 10 kg ha-1. Studies have shown that in the location of Futog (region of south Bačka), sowing 10 kg ha-1 with row distance of 25 cm provides red clover seed yield of 482.4 kg ha-1 in the first year of growing and 546.2 kg ha-1 in the second year. The highest yield of dry matter grown in the system of production for mixed use (seed-forage) in Futog was achieved with the row distance of 12.5 cm and seeds rate of 10 kg ha-1.

U radu je proučavan uticaj međurednog rastojanja i setvene norme na prinos semena i suve materije crvene deteline u sistemu proizvodnje za kombinovano iskorišćavanje. Dvogodišnja poljska istraživanja (2006. i 2007) obavljena su u Poljoprivrednoj školi u Futogu. Usev crvene deteline je zasnovan na tri međuredna rastojanja: 12,5 cm, 25 cm i 50 cm, sa tri setvene norme: 2,5 kg ha-1, 5 kg ha-1 i 10 kg ha-1. Najveći prinos semena u sistemu proizvodnje crvene deteline za kombinovano iskorišćavanje (seme-krma) tokom obe posmatrane godine je dobijen setvom na 25 cm međurednog razmaka i sa količinom semena 10 kg ha-1, dok je najveći prinos suve materije ostvaren sa istom setvenom normom na 12,5 cm međurednog razmaka.
