In the modern market conditions of Ukraine, the basis of crop cultivation technologies is their economic efficiency. The purpose of the research was to study the economic and energy efficiency of growing coriander plants under the influence of the fertilization system and seed sowing rates.
The following research methods were used: field, laboratory and statistical.
It was established that the application of fertilizers at the rate of N90P40K80 against the background of the sowing rate of 2,5 million pcs./ha is the most profitable measure for the studied varieties – 250 %, the conditional net profit was UAH 22218,0/ha. Under the conditions of increasing the fertilizer rate to N135P60K120, the conditional net profit decreases to UAH 20215,0/ha. At the same time, the cost of 1 ton of seeds increases. If the rate of seed sowing is increased, economic indicators also tend to decrease. The highest energy yield (35532 MJ/ha) was recorded when using N90P40K80 mineral fertilizers and a seeding rate of 2,5 million units/ha, while the N45P20K40 fertilizer option with a seeding rate of 1,5 million units/ha was 1.8 times less. The highest energy consumption was observed when using mineral fertilizers in the rate of N135P60K120 when using the rate of sowing coriander seeds of 3,0 and 2,5 million units/ha. 21601 and 21529 MJ/ha, respectively.
Cultivation of coriander is quite energy efficient, the coefficient of energy efficiency varied depending on the investigated factors within the range of 1,61−2,54.
