Effect of agroecological factors on buckwheat yield in conventional and organic cropping systems

This study was carried out on Institute of Field and Vegetable Crops, fields in Backi Petrovac, Serbia in conventional (2010-2012) and organic (2012) cropping systems. The results of four buckwheat varieties: Novosadska, Darja, Prekmurska and Francuska are presented here. The average yield that all tested buckwheat variety obtained in 2010 was significantly higher than 2011 value, respectively (p lt 0,05). Genotype, year and their interaction showed statistical significance (p lt 0.05, p lt 0.01). The differences of significance from the point of production cropping systems on the average value of the traits were statistically not significant (p gt 0.05). This piece of data is extremely important because of the knowledge that buckwheat can be successfully grown in organic production. Istraživanja su sprovedena na parcelama Instituta za ratarstvo i povrtarstvo, u Bačkom Petrovcu, u uslovima konvencionalnog, 2010-2012.,i organskog sistema gajenja, tokom 2012. U radu su prikazani rezultati ispitivanja četiri sorte heljde: Novosadska, Darja, Prekmurska i Francuska. Prosečni prinosi heljde kod svih ispitivanih genotipova u 2010. godini bili su visoko signifikantno viši u odnosu na 2011. godinu (p lt 0,05). Genotip, godina i njihova interakcija pokazuju statističku značajnost (p lt 0.05). Ustanovljene razlike značajnosti sa stanovišta uticaja sistema proizvodnje na prosečne vrednosti ispitivanih osobina statistički nisu bile signifikantne (p >0,05). Ovaj podatak je izuzetno važan zbog saznanja da se heljda može vrlo uspešno proizvoditi i u organskoj proizvodnji.
