The influence of green manure crops on the growth, development, yield and fruits quality of eggplant

Abstract

The effectiveness of the use of beans (Phaseolus vulgaris L.), peas (Pisum sativum L.) and soybeans (Glycine max (L.) Merr.) belonging to the Fabaceae family was studied to identify the possibilities of use them as green manure to increase soil fertility and eggplant yield. The option without green manuring was accepted as a control. Experiments were conducted in 2021-2022. As a result of green manuring, available nitrogen content in the soil (N) increased by 20.8- 76.8%, phosphorus (P2O5) – by 58.6-89.6%, and potassium (K2O) – by 5.9-6.4%. The best result was observed in case of using soybean as siderat crop, where the volume weight of the soil decreased by 0.189g/sm3. The utilization of green manure crops had a positive effect on eggplant yield, surpassing the control in the case of soybeans by 24.3%, in beans option - by 18.2%, and in case of peas - by 14.5%. The results of the study conducted confirm that the application of the recommended green manure plants under the conditions of the Ararat valley of the Republic of Armenia has a positive effect on the growth and development of eggplant, as well as on yield and fruit quality indicators.
