Highly significant negativecorrelations existed between seed yield and precipitation data: for growing season (May-August),r = -0.667 ** ; for June-August, r = -0.660 ** , and for July-August, r = -0.761 ** , respectively.Numerous authors (Ņarinov & Kljuj, 1990; Huyghe et al., 2001; Bolanos-Aguilar et al., 2002;Karagić et al., 2007; Stjepanović et al., 2009) agree that variation in alfalfa seed yield isprimarily due to weather conditions in the year of growing. Among them, the total amount anddistribution of rainfall were most important.41
