DETERMINATION OF THE EFFECTS OF DIFFERENT WATER STRESSES ON SOME QUALITY CHARACTERISTICS OF SILAGE SORGHUM

Abstract

This study was conducted to determine the effects of different water stresses on some quality characteristics of silage sorghum in Konya ecological conditions in 2017-2018 years. The study were conducted in randomized blocks design with three replications under. In this study four different irrigation levels were applied (I1: Full irrigation, I2: 75 % of I1, I3: 50 % of I1 and I4: 25 % of I1). According to the results of the first year (2017), the crude protein ratio (CP) varied between 8.0% (I4)- 10.1 (I1), acid detergent fibre (ADF) between 32.0 % (I4)-35.6 (I1), neutral detergent fibre (NDF) between 52.4% (I4)-57.7 (I1), ash content (Ash) between 6.9% (I4)-7.6 (I2), % digestible dry matter (DDM) between 61.2% (I1)- 64.0% (I4), % dry matter intake (DMI) between 2.1 (I1)- 2.3 (I4), relative feed value (RFV) between 92.1% (I1)-106.6 (I3) and cellulose ratio (CR) was 25.0% (I4)-27.2 (I1). In the second year, CP varied between 7.9% (I4)-9.9% (I1), ADF between 32.5% (I4)-35.3 (I1), NDF between 53.6% (I4)-57.1 (I1), CR between 25.3% (I4)-26.9% (I1) ash between 7.2% (I3)-7.8 (I1), DDM between 61.3% (I1)- %63.6 (I4), DMI between 2.1 (I1)- 2.2 (I3) and RFV between 90.3% (I1)-104.8 (I4).
