Effects of nitrogen, boron and row spacing on rapeseed productivity
Uticaj azota, bora i načina setve na produktivnost uljane repice
Апстракт
The two-year field experiment was set up according to the completely randomized block design with four replications on chernozem soil type. Five treatments of nutrition (N0, N120, N140, N120+B, N140+B) and two different row spacing (12 cm and 24 cm) were applied. The highest two-year average seed yield (5.72 t ha-1) occurred in the variant with the most intensive nutrition (N140+B) and 24-cm row spacing. The application of both nitrogen rates decreased the oil content (by 6.7% and 12.1%). The effect of the B foliar application was more pronounced in the second year, when a lower content of this micro nutrient was determined in the soil. The number of pods and 1000-seed weight significantly increased with the N140 treatment. The cultivar Jet Neuf expressed an intensive respond to a wider row spacing by developing more branches and pods (19% and 31%), that resulted in a higher seed yield (22.8%).
Dvogodišnji poljski ogled bio je postavljen po planu potpuno slučajnog blok sistema u četiri ponavljanja, sa pet nivoa ishrane: N0, N120, N140, N120+B i N140+B i dva načina setve: na 12 cm i 24 cm međurednog rastojanja, na zemljištu tipa izluženi černozem. Najviši prinos semena u proseku za dvogodišnji period (5,72 t/ha) postignut je najintenzivnijom ishranom (N140+B) i setvom na 24 cm. Sa povećanjem količine azota vrlo značajno je opadao sadržaj ulja u semenu (u proseku 6,7% i 12,1%). Efekat ishrane borom bio je veći u drugoj godini, kada je zemljište bilo njime slabije obezbeđeno. Ishranom sa 140 kg/ha azota značajno je povećan broj plodova i masa 1000 semena. Sorta Jet Neuf je ispoljila veliku plastičnost na oblik vegetacionog prostora, obrazujući više bočnih grana i plodova (19% i 31%) i sa 22,8% višim prinosom kod varijanti sa većim međurednim rastojanjem.
