Uticaj načina zaštite semena ozime pšenice protiv Tiletia tritici na komponente prinosa

Abstract

Researching was done in field condition with three variety of winter wheat and seven ways of seed protection. Researching shown that the way of seed protection was factor that have significance influence on researched characteristics. Our researching shown that among the same way of protection hadn't been significance difference among researched variety of wheat in number plants and spike per m2, coefficient of productive bushing and grain yield . Number plants per m2 arrised from 484 at variety PKB-Christina to 520 at variety Vizija. According to the way of protection per m2 arrised from 487 at treatment Tilletia tritici+ Sumi 8 to 517 at electronic way of protection. The number of spike per m2 arrised from 721 at variety PKB-Christina to 732 at variety Pobeda. According to the researched ways of protection the number of spike is established from 711 at control to the 746 at treatment with Tlletia tritici. Coefficient of productive bushes is established was 1,43 at variety Vizija to 1,49 at variety Pobeda. According to the way of seed protection coefficient of productive bushes as established at control 1,44 to treatment Tilletia tritici + Sumi 8. 1,50. Yield of grain is established at variety Vizija 7,03t/ha and variety Pobeda 7,69t/ha. According to the way of grain yield protection was 7,19 t/ha and at control was 7,56 t/ha with Dividendom 030 protection.

Istraživanja su izvedena u poljskim uslovima, sa tri sorte ozime pšenice i sedam načina zaštite semena. Utvrđeno je da je način zaštite semena faktor koji znatno utiče na ispitivana svojstva. U okviru istog načina zaštite nema razlika u broju biljaka i klasnova po m2, u koeficijentu produktivnog bokorenja i prinosu zrna. Broj biljaka po m2 kretao se od 484 kod sorte PKB-Christna do 520 kod sorte Vizija, broj klasova po m2 od 721 kod sorte PKB-Chistina do 732 kod sorte Pobeda, koeficijent produktivnog bokorenja od 1.43 kod sorte Vizija do 1.49 kod sorte Pobeda, a prinos zrna od 7.03 t/ha kod sorte Vizija do 7.69 t/ha kod sorte Pobeda. U odnosu na način zaštite broj biljaka po m2 kretao se od 487 kod tretmana Tilletia tritici + divikonazol, do 517 kod elektronskog načina zaštite, broj klasova od 711 kod kontrole do 746 kod tretmana sa Tilletia tritici, koeficijenat produktivnog bokorenja od 1.44 kod kontrole do 1.50 kod tretmana Tilletia tritici + divikonazola, a prinos zrna od 7.19 t/ha kod kontrole do 7.56 t/ha kod zaštite sa difenokonazolom.
