Abstract:

The use of absorbents from Maximarin for growing spinach contributed to its faster germination, increased plant growth and development, and resulted in an increase in yields of commodity products by 2.0–6.1 t ha-1 and an increase in chemical composition. The use of absorbents in open ground for spinach made it possible to obtain the highest amount of contingent net profit for making the drug Maximarin in the form of a gel and the company Eco – with small granules, and in the Krasen Polissia variety – 2,160 and 2,102 USD ha-1, in the Malakhit variety for introduction the drug Maximarin in the form of a gel 1,949 USD ha-1 and the company Eco absorbent with potassium – 1,575 USD ha-1. Profitability for the Matador variety has reached 75%, Malakhit grade – 69–75%, Keb – 3.0–3.2. It was established that in the closed ground application of the drug Maximarin in the form of gel and granules for spinach made it possible to obtain the highest amount of contingent net profit, which was Matador 3,079 and 3,025 USD ha-1, in the Malakhit variety for the introduction of gel 4,304 USD ha-1 and granules – 4,245 USD ha-1. Profitability for the use of drugs for the Krasenʹ Polissia variety reached 84–77%, Malakhit – 118–116%, the bioenergy efficiency ratio – 3.0–3.3.
