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.
