EFFECT OF PHOSPHORUS FERTILIZATION ON SILAGE QUALITY OF PERSIAN CLOVER (TRIFOLIUM RESUPINATUM L.)

Abstract

The aim of the research was to determine the effect of phosphorus fertilization (0, 30, 45, 60, 75 and 90 kg ha-1) on silage yield and quality traits of Persian clover (Trifolium resupinatum L.). The experiment was conducted at Yoruk village of Malkara-Tekirdag with three replications in randomized block design in 2021. Silage yield (t ha-1), dry matter (%), crude protein (%), crude ash (%), acid detergent fiber (ADF, %), neutral detergent fiber (NDF, %), P (%), K (%), Ca (%), Mg (%), digestible dry matter (DDM, %), dry matter intake (DMI, %), relative feed value (RFV), total digestible nutrients (TDN), net energy-lactation (NEl), net energy-maintenance (NEm), net energy-gain (NEg) and flieg score were determined. Silage yield, dry matter, pH, crude protein, ADF, NDF, P, Mg, DDM, DMI, RFV, TDN, NEg and Flieg Score were determined statistically significant at P˂0.01. The highest silage yield (72.83 t ha-1) and ADF ratio (25.36 %) were obtained from 30 kg P ha-1. The highest dry matter (39.92 %), DDM (70.30 %), DMI (3.22 %) RFV (175.056) and TDN (68.90) were found at application of 90 kg P ha-1. The highest flieg score was determined at application of 60 kg P ha-1. The highest crude protein (15.50-15.51 %) was found at application of 45 and 60 kg P ha-1.
