Summary

We have analyzed the 1999-2002 seed production of the Novi Sad varieties of alfalfa, field pea arn;L vetch that predominate the commercial production in the Vojvodina Province. The average alfalfa yield of 260 kg/ha was at the level of the long-term average, but the annual variations wdre large, from 100 to 362 kg (Table 3). The highest yield was achieved in 2002 with the variety NS-Banat ZMS II, 675 kg/ha. High values were registered for the major quality indicators. The average seed purity was 99.6%, with small annual variations from 99.4 to 99.8% (Table 4.). Furthet- to tl;ie ,point, t_he largest portion of admixtures was made up of inert matter (0.3%), while weed seeds could be found only in traces (0.1 %). Depending on the weather conditions of the year of produFtion, seed viability ranged from 83 to 86%. The average contents of atypical seedings and hard seeds were low, 6.8% and 4.5%, respectively. The mass of 1000 seeds was 2.1 g, with the average moisture content of 7.3%. Depending on the purpose of production, field pea seed yields .varied between 1601 kg/ha (NS-Pionir) and 3131 kg/ha (Javor) (Table 5). The analyzed period had unfavorable ecological conditions for vetch production, which resulted in low yields, from 1271 kg/ha (NS­Sirmium) to 1550 kg/ha (Beograd) (Table 6). Field pea seed purity was 99.4%, with 0.6% of inert matter and no seed admixtures,. of other crops or weeds. Vetch seed purity was 98.9% (98.3 99.3%). The largest portion df admixtures was inert matter (0.8%), while seed of other crops made 0.3%. Weed seeds were not present. The values for seed viability of field pea and vetch were 90.3 and 93.3%, respectively, with small variations due to ecological conditions (Table 7).
