Description
Agroclimatic resourses of the North-West of the USSR allow to produce up to 10 t/ha of grasses dry matter and to accumulate up to 2.4% of photosynthetic active radiation (PhAR) in the yield for vegetation period. We proved experimentally the possibility of increasing yielding capacity up to 16 t/ha of dry matter and PhAR indices up to 3% through establishment of tall fescue Occidental grass stands with 1900-2000 shoots per m2, optimization of nutritive (N480 P130 K360), water (0.75 MVC-1.0 MWC) regimes and through clipping frequency (3 cuts). During vegetation period, such grass stands had a powerful assimilation mechanism: leaf area-92 th. m2/ha, photosynthetic potential-7 .12 million m2/ha • day, pure photosynthetic produtivity-2.68 g/m2 • day, and accumulated 3.3% of the comimg PhAR.
