title: IMPACT OF PLANT BIOMETRIC CHARACTERISTICS ON SEED PRODUCTIVITY OF CASTOR-OIL PLANT AND SWITCHGRASS DEPENDING UPON WEATHER CONDITIONS OF THE VEGETATION PERIOD IN THE FOREST-STEPPE OF UKRAINE
abstract: The article has demonstrated the necessity of investigating new, alien crops such ascastor-oil plant (Ricinus communis L.) and switchgrass (Panicum virgatum L.) as a raw material for production of biofuel and by-products for different fields of industry. The detailed description of plant morphology, and practices regarding increase of seed germination ability of the studied crops have been given. Solid literature overview has been made and attention has been emphasized on the up-todate of the re
