Influence of genotypes and digestate on the productivity of the morphological indicator of silage-sorghum as high quality feed

Abstract

Fodder sorghum is used for preparing silage in the phase of milk-wax maturity, when sorghum contains 65-70% water. Sorghum silage is mostly used in the diet of dairy cows. Since sorghum contains a lot of sugar, silage is successfully prepared without the addition of additives. Sorghum forms a large biomass during the year. After each mowing the plants regenerate giving a new swath. The aim of this study is to examine the influence of digestate on sorghum productivity in the conditions of Vojvodina. Digestate had a great influence on plant productivity. Based on the analysis of variance, it is evident that there is a significant difference in the number of leaves per plant in relation to the variant (Fekp = 7.118 *).

Krmni sirak se koristi za spremanje silaže u fazi mlečno-voštane zrelosti, kada sirak sadrži 65-70% vode. Silaža od sirka najviše se koristi u ishrani mlečnih krava. Pošto sirak sadrži dosta šećera, silaža se uspešno sprema bez dodavanja aditiva. Sirak formira veliku biomasu tokom godine, posle svake kosidbe biljke se regenerišu dajući novi otkos. Cilj ove studije je da se ispita uticaj digestata na produktivnost sirka u uslovima Vojvodine. Digestat je imao veliki uticaj na produktivnost biljaka. Pokošena biomasa može se spremati kao senaža, sinaža ili se suši. Sveža biomasa sirka za ishranu domaćih životinja može se koristiti kad provene nekoliko sati da bi se razložile štetne supstance. Tokom godine može se dobiti preko 70 t ha-1 sveže biomase sirka.
