Seed spacing and depth in winter rye sowing

Abstract

Proper seed distribution over area and depth is the essential condition that provides later uniform plants distribution over the vegetation space. Paper presents statistical analysis of two drills accuracy results in winter rye sowing. Experiment was done in north Kosovo, during rye sowing with two mechanical seed drills, OLT Gama and IMT 634.23. Besides the comparative analysis of the sowing results achieved by these two drills, in the paper is tested and verified the applicability of Gaussian function for analytical description of longitudinal, transverse and depth distribution of winter rye seed at the experimental plot.

Pravilna raspodela semena po površini i dubini predstavlja osnovni uslov za obezbedjenje ravnomerne raspodele biljaka u vegetacionom prostoru. U radu je predstavljena statistička analiza rezultata ispitivanja tačnosti distribucije semena dve uskoredne sejalice u setvi ozime raži. Ispitivanja su izvedena na severu Kosova, u toku setve semena raži primenom dve sejalice Olt Gama 14 i IMT 634.23. Osim komparativne analize rezultata setve koji su dobijeni primenom ove dve sejalice, u radu je testirana i proverena primenljivost Gausove funkcije za analitičko opisivanje uzdužne, poprečne i raspodele semena ozime raži po dubini na eksperimentalnoj parceli.
