Purpose . To determine the economic and energy efficiency of agro-technological methods of lentil cultivation. Methods . Field and calculation-economic. Results The article presents the indicators of the efficiency of lentil cultivation as affected by the effect of seeding timing, micronutrients, growth regulators and their combination. It was established that application of growth regulators on the sowings sown early led to a maximum yield of 2.37 t/ha (Stimpo). Taking into account the cost of lentil crop, production costs and yield, economic efficiency of growing the crop was calculated. Thus, the most cost-effective options were micronutrients and growth regulators, since the production costs per hectare varied from UAH 9360 in the treatment with Reakom-SR-Legumes + Regoplant to UAH 9410 in the treatment with Quantum Legumes + Stimpo. However, the use of additional agronomical measures allowed to generate the highest level of profit for the 1-st sowing date in the treatment with Stimpo (UAH 78510), while for the 2-nd sowing date the best was the treatment with Reakom-SR-Legumes + Stimpo (UAH 65360). Therefore, when sowing on the 2-nd sowing date, the micronucrients and growth regulators should be applied in order to obtain high yield and the best combination is Kvantum-Legumes + Regoplant or Reakom-SR-Legumes + Stimpo. The energy efficiency ratio when applying Stimpo growth regulator was by 4.6 % higher than that of the control treatment of the 1-st sowing date. Conclusions It has been established that from the economic point of view, the best for lentil was early sowing and the treatment with the growth regulator Stimpo. Thus, in this treatment we have the highest production value of UAH 87690 along with the lowest production cost of UAH 3870 per hectare and the maximum profit of UAH 78510 per hectare. For the later sowing date, Reakom-SR-Legumes + Stimpo should be used to obtain high profit with the production value of UAH 74740 per hectare, production costs of is UAH 4640 per hectare and the profit of UAH 65360 per hectare. |
