Determination of the optimal concentration of organic fertilizers for the sowing qualities of crops using the example of pumpkin

Abstract

The research of the effectiveness of the obtained fertilizers impact on the sowing characteristics of pumpkin seeds Cucurbita pepo L. was conducted at the Center for Collective Use "Advanced Technologies and Materials" of the Sevastopol State University. The work provides data on the effect of organic fertilizers based on vermicompost and chicken manure on the sowing qualities of pumpkin seeds. A comparative analysis of the energy of germination and laboratory viability of the seeds, root and sprout growth of the agricultural crop Cucurbita pepo L. was carried out. To compare the results obtained, the certified fertilizers “Power of Growth” and “Riverm” based on vermicompost were taken. The optimal concentration of chicken manure was identified with a concentration of 200 mg per 2 liters based on the germination energy, the values were 87% and the viability 95%. Also, the increase in the sprout length for the fertilizer based on chicken manure was 127.7%, which is 15% more than the “Power of Growth” fertilizer. Test samples based on vermicompost gave negative results: root growth – minus 21.9%, negative shoot growth – minus 6.3%. A method for producing new types of organic fertilizers based on chicken manure, based on the cavitation effect, has been described. An assessment of the effectiveness of using fertilizers for an agricultural crop – pumpkin Cucurbita pepo L. has been made.
