The influence of variety and date of sowing on soybean yield

Abstract

Results of soybean yield and crude proteins content testing of several soybean varieties conducted in 2005. on 12 locations in Backa, Srem and Banat are layed out this project. Also seeding period influence on soybean yield of several agricultural organizations in perennial period was analyzed. Seed yield of early varieties (0 maturity group) varied from 2393 - 4352 kg/ha; I group of varieties varied from 2957 - 5475 kg/ha and late varieties (II maturity group) varied from 2615 - 5551 kg/ha. Considering the location the highest average yield (4309 kg/ha) was obtained with BG-L-3 genotype and the lowest (3538 kg/ha) with the Afrodita variety. Considering the results of these testing as well as many other testing, crude protein content is in negative correlation with soybean yield. Protein content, expressed in absolute mass of dry soybean, varied from 42.05% (variety Vojvodjanka - location Becej) to 49.49% (variety Dukat - location Vajska). Agricultural organizations, especially "Jedinstvo" Apatin and "Stari Tamis" Pancevo, which practice very early sowing (end of March and beginning of April) obtains significantly higher seed yield then the organizations which practice late sowing. .

U radu su prikazani rezultati prinosa zrna i sadržaja sirovih proteina ogleda većeg broja sorata soje izvedenih 2005. godine na 12 lokacija u Bačkoj, Sremu i Banatu. Osim toga, analiziran je uticaj vremena setve na prinos soje većeg broja poljoprivrednih organizacija u višegodišnjem periodu. Prinos zrna ranostasnih sorata (O grupa zrenja) je varirao od 2.393 do 4.352 kg/ha; sorata I grupe od 2.957 do 5.475 kg/ha i poznih sorata (II grupa zrenja) od 2.615 do 5.551 kg/ha. U proseku za lokacije, najveći prinos (4.309 kg/ha) postignut je kod genotipa BGL- 3, a najmanji (3.538 kg/ha) u sorte Afrodita. Prema rezultatima ovih istraživanja, kao i mnogih drugih, sadržaj sirovih proteina je u negativnoj korelaciji sa visinom prinosa zrna. Izražen u apsolutno suvoj masi zrna, sadržaj proteina je varirao od 42,05% (sorta Vojvođanka-lokacija Bečej) do 49,49% (sorta Dukat-lokacija Vajska). Poljoprivredne organizacije, naročito "Jedinstvo" Apatin i "Stari Tamiš" Pančevo, koje soju seju vrlo rano (kraj marta i početak aprila) postižu značajno veći prinos nego organizacije koje seju kasnije. .
