Abstract

This study investigates the efficacy of green manures in raising soil fertility and enhancing crop productivity, focusing on Albic Luvisols in northwestern Romania. Green manures, are cover crops that offer a multitude of benefits when incorporated into the soil. Peas emerge as particularly potent in enriching soil with organic nitrogen, leaving a substantial amount of 471.74 kg N(a.s.) per hectare. Despite pathogen pressures, notably from Septoria helianthi and Puccinia helianthi, the yield was not affected. Incorporated green manures, especially peas and soybean, significantly boosts sunflower yield, surpassing the control by over 1000 kg/ha. Moreover, chemical fertilization further enhances yield, yielding a substantial difference of 398 kg/ha between fertilized and unfertilized variants. Furthermore, green manures influences sunflower seed fat content, with triticale green manure variant resulting in the highest fat content, with a difference of 3.02% compared to the control. However, it is important to note that the thousand-grain weight (TGW) of sunflower seeds is affected by green manures, particularly with triticale showing a considerable difference of (-) 8.47 g compared to the control. These findings underscore green manures' impact on soil health, yield, and seed quality, affirming their potential as sustainable agricultural practices for enhancing agroecosystem resilience and productivity.
