Effects of irrigation dates and rates on absolute seed weight in sugar beet seeds of different fractions

Abstract

The known effects of 1000-seed weight on quality traits in sugar beet seeds have led us to investigate the effects of irrigation dates and rates on 1000-seed weight of this crop. Statistically significant differences were observed for both the irrigation and the amount of water applied. 1000-seed weight increased from the first to the third irrigation date. The third irrigation date, 45 days after the flower stalks began to form, produced the largest 1000-seed weight. The largest 1000-seed weight was also observed in the treatment with 45-55 mm of water, and the difference between that and the treatment with 25-30 mm water was statistically significant.

Poznati uticaj mase 1.000 semena na ostale kvalitetne osobine semena šećerne repe, dao nam je zadatak da se istraži uticaj rokova i norme zalivanja na masu 1.000 semena šećerne repe. Statistički opravdane razlike ostvarene su kod rokova zalivanja i količine vode. Masa 1.000 semena rasla je od prvog do trećeg roka zalivanja. Treći rok zalivanja posle 45 dana od početka formiranja cvetnog stabla ostvario je najveću masu 1.000 semena šećerne repe. Najveća masa 1.000 semena bila je od 45 mm do 55 mm vode sa opravdanim razlikama u odnosu na 25 mm do 30 mm vode.
