The influence of plant density on hybrid sunflower seed yield
Uticaj gustine useva na prinos semena hibrida suncokreta
Апстракт
During two-year period (2003 and 2004), the influence of plant density (30,40 and 50.000 plants per ha) on NS hybrid sunflower seed yield of different length of vegetation period (NS-Velja, NS-H-111 and NS-H-45). Research was carried out by field micro experiments in agroecological conditions of North Backa (Apatin) on carbonate humogley soil type. Experiments were conducted by split plot method in four replications. The results show that, by examining the plant density and hybrids, significant differences in seed yield of sunflower were made. In years with more favorable weather conditions (2003) during the growing period, increased plant density showed a stronger effect on seed yield in comparison with 2004 year which had the adverse weather conditions.
U dvogodišnjem periodu (2003. i 2004. godine) ispitivan je uticaj različitih gustina useva (30, 40 i 50.000 biljaka po ha) na prinos semena NS hibrida suncokreta različite dužine vegetacionog perioda (NS-Velja, NS-H-111 i NS-H-45). Istraživanja su obavljena putem poljskih mikroogleda u agroekološkim uslovima severne Bačke (DPP "Jedinstvo Apatin") na zemljištu tipa karbonatna ritska crnica. Ogledi su postavljeni po metodi razdeljenih parcela (split plot) u četiri ponavljanja. Dobijeni rezultati istraživanja pokazuju da su, u godinama proučavanja, između ispitivanih gustina useva i hibrida ostvarene značajne razlike u prinosu semena suncokreta. U godini sa povoljnijim meteorološkim uslovima (2003) tokom vegetacionog perioda suncokreta, povećana gustina useva ispoljila je snažniji uticaj na prinos zrna u poređenju sa 2004. godinom koja se odlikovala nepovoljnijim vremenskim uslovima.
