KUKUSHEVA, А. and A. STEPANOV, 2016. Effect of mowing term on biometrics, yield and nutritional properties of hybrid (Rumex patientia х Rumex tianschanicus). Bulg. J. Agric. Sci., 22: 948–954
Expanding the range of food plants enables to balance the ration of animals and organize assembly-line production of feed. Promising in this respect is a hybrid sorrel (Rumex patientia x Rumex tianschanicus). According to its biological characteristics it belongs to early crops, which is important for regions with a short frost-free period. The aim of our research was to investigate the effect of mowing term to biometric parameters and productivity of sorrel, the dynamics of green mass and nutrients accumulation during the growing season and identifi cation of the optimum periods of grass harvesting at maximum productivity. Mowing and measurements of biometric indicators of sorrel grass we carried out every 10 days. We have found that the greatest productivity of sorrel hybrid forms is in phases beginning of blooming to - blooming (10–20 June). Under these terms a yield of green mass was 34.7–35.1 t ha–1, crude protein 849–885 kg ha–1, with a maximum daily increase of green mass of 1050 kg ha–1 per day.
