Experiences and Prospects of Paisa Management on the Drained Lands of Polissia Ecozone

The research identified key technological parameters for growing paisa on drained lands of Polissia Ecozone. Various criteria, such as productivity, adaptability, energy and nutritional value, and usage potential, were used to assess the feasibility of growing paisa. Pilot studies at the Rivne Region, Ukraine showed significant yields even in adverse weather conditions. Proper sowing timing is crucial, with early sowing risking weed overgrowth and frost damage, while late sowing may hinder germination. The optimal sowing date was determined to be May 15, resulting in 8.1–16.7% more green mass and 2.1–9.6% more dry matter at all growth stages. The research established technological parameters for different growth stages, taking into account critical water availability periods, agronomic practices, and recommended fertilizer norms for peat soils. It found that maintaining soil moisture levels between 65% and 75% is optimal, based on field capacity. Guidelines were also provided for drainage systems to effectively remove excess water and maintain optimal GWL. Climate change in Polissia presents challenges for growing paisa due to uneven rainfall and temperature fluctuations. Planning for water accumulation in reservoirs for irrigation during drought periods is essential to support sustainable crop growth under changing climate.
