Dependence of rapeseed quality and yield on density, variety and year of production

Abstract

Rapeseed is an important industrial plant in the world. In Vojvodina region of Serbia it is grown on well aerated and deep soils. Most often it is sown with the distance between the rows of 25 cm, and 5-6 cm within the row. The trial with three winter rapeseed genotypes (Banaćanka, Slavica and NS-H-2) was set up at Rimski Šančevi (Vojvodina) during growing seasons of 2009/2010 and 2010/2011. Seed was sown with inter row spacing of 25 cm, and spacing within the rows of 5 cm, 8 cm, 10 cm and 16 cm. The following parameters were tested upon harvesting: seed germination, 1000 seed weight, test weight, seed yield, oil content and total protein in seed. No effect of planting density was observed on rapeseed seed quality produced in 2009/10 and 2010/11, which should be kept in mind when determining the quantity of seed required for sowing.

Uljana repica je značajna industrijska biljka u svetu. U Vojvodini se najčešće gaji na dobro aerisanim i dubokim zemljištima. Setva se najčešće vrši sa razmakom između redova 25 cm, a u redu 5-6 cm. Ogled sa tri genotipa ozime uljane repice (Banaćanka, Slavica i NS-H-2) je postavljen na Rimskim šančevima (Vojvodina) u vegetacionoj sezoni 2009/2010. i 2010/2011. Setva je izvršena u redove sa međurednim razmakom 25 cm i razmakom u redu od 5 cm, 6 cm, 8 cm, 10 cm i 16 cm. Nakon žetve ispitani su sledeći parametri: klijavost semena, masa 1000 semena, zapreminska masa, prinos semena, sadržaj ulja i ukupnih proteina u semenu. U našim ispitivanjima nije utvrđen uticaj sklopa na kvalitet semena uljane repice proizvedenog u vegetacionoj sezoni 2009/10. i 2010/11. što treba imati u vidu prilikom određivanja potrebne količine semena za setvu.
