Primena novih biotehnoloških rešenja gajenja goveda, ovaca i koza u cilju dobijanja biološki vredne i zdravstveno bezbedne hrane (MPNTR - 31053)

Sažetak
Ispitivanja su rađena u Institutu za stočarstvo u trogodišnjem periodu ispitivanja u poljskim i laboratorijskim uslovima. U eksperiment su uključene dve smeše trava i leguminoza: Smeša A (lucerka (K-28), 50% i ježevica (cv. K-40), 50%) i Smeša B (lucerka (K-28), 33,3%, ježevica (cv. K-40), 33,3% i visoki vijuk (cv.K-20), 33,3%), kao i čist usev lucerke (M). Ogled je izveden po metodu slučajnog blok sistema u četiri ponavljanja, Đubrenje travnjaka je obavljeno split metodom, količinama od 0, 70 i 140 kgN ha-1. Cilj ovih istraživanja je da odredi fitocenološku postojanost smeša lucerke (Medicago sativa L.) sa ježevicom (Dactylis glomerata L.) i visokim vijukom (Festuca arundinacea Schreb.), prinos i kvalitet dobijene stočne hrane sa travnjaka u zavisnosti od sastava smeše i đubrenja azotnim đubrivima. Ispitivani faktori imali su statistički značajnog uticaja na prinos suve materije i prinos proteina. Lucerka je ostvarila značajno veće prinose u odnosu na njene smeše. Prinosi suve materijeSM su se povećavali dodatkom N mineralnih đubriva. Prinos proteina bio je najveći u čistom usevu lucerke, a zatim u smeši lucerke i ježevice. Đubrenje je takođe povećalo prinos proteina.
