The Mineral, Amino Acid and Fiber Contents and Forage Yield of Field Pea (Pisum Arvense L.), Fiddleneck (Phacelia Tanacetifolia Benth.) and Their Mixtures Under Dry Land Conditions in the Western Turkey

Abstract

The objective of this research was to determine the yield and forage quality traits (green fodder yield, dry matter yield, amino acid, fibre and mineral contents) of field pea (Pisum arvense L.), fiddleneck (Phacelia tanacetifloia Benth.) and their mixtures under dry land conditions. The field pea was sown with fiddleneck as follow: field pea 75% + fiddleneck 25%; field pea 50% + fiddleneck 50%; field pea 25% + fiddleneck 75%. Besides, pure field pea and fiddleneck were sown. The highest green fodder (50.2 t ha-1) and dry matter yield (10.3 t ha(-1)) were obtained from 50% field pea + 50% fiddleneck mixture, while minimum green fodder yield (40.1 t ha(-1)) and dry matter yield (7.8 t ha(-1)) were recorded in pure fiddleneck. The maximum total AA (125.7 g kg(-1)) and CP (150.4 g kg(-1)) were found in pure field pea. The highest NDF (44.0-44.7%) and ADF (37.1-38.1%) were determined for pure fiddleneck and 25% field pea + 75% fiddleneck mixture, respectively. The effects of species and different mixture ratios on K, P, Ca and Mg contents were significant. The differences between species and mixtures for cystine contents (0.3-0.4 g kg(-1)) were non-significant. The species and mixtures affected all other AA contents.
