Abstract
The major factors of the slow spreading of lucerne seed production in our country are low and unstable yields due to an inadequate cultivation technology. Time mowing first growth on alfalfa are known to be the major factors affecting lucerne seed yield. In a field trial in 1997-98 in Yugoslavia the lucerne cv. Osječka 66, were mowing of first growth: 1. 20.april; 2. 01.may; 3. 10.may; 4. 20.may. Trial was conducted in non irrigated, very deep clay soil (Silas, north-western Yugoslavia). The highest lucerne seed yield was achieved with plants mowing of 01. may (565.3 and 826.1 kg ha-1 in 1997 and 1998 respectively). With 1. 20.april; 2. 10.may; 3. 20.may. mowing of first growth seed yield amounted to 485,2 650,3 and 519,4 kg per ha. The advantage of first plants mowing was especially significant for the moist growing season of 1997 when the seed yield amounted to 565,3 kg per ha with mowing of 01. may.
