Yield and quality performances and some physiological properties of artificial pasture mixture in irrigated and dry conditions

This research aimed to investigate the yield and quality performance of alfalfa, white clover, and perennial grass species in single, double, and triple mixtures in artificial pasture establishment under both irrigated and dry conditions, along with some physiological characteristics of the species. The experiment was conducted between 2020 and 2022 across 48 plots with four replications. It was determined that total green grass yield varied between 2061-2964 kg/da in irrigated conditions and 1165-1641 kg/da in dry conditions. It was determined that dry grass yield varied between 787.5-1270 kg/da in irrigated conditions and 515-764 kg/da in dry conditions. In quality analyses, the highest crude protein ratio value was obtained from the planting of pure alfalfa in dry conditions (17.6%) and the lowest value was obtained from the planting of pure perennial grass in dry conditions (8%). The highest NDF ratio was determined from the data averages of pure perennial grass in both water conditions (54.2%; 53.4%). The highest vegetation temperature value of 32.5 0 C was obtained from the pure planting of white clover and from the binary mixture (AI) of white clover with perennial grass in dry conditions. The highest stomatal conductance was determined in the measurement of the mixture planting of white clover with perennial grass (Aİ: 94.8 mmol m-2s-1) under irrigated conditions. The highest chlorophyll content was determined in the triple mixture (59.3 SPAD), binary mixture (59.1 SPAD) and single planting (56.8 SPAD) of alfalfa under irrigated conditions.
