The results revealed that sunnhemp incorporation significantly outperformed cowpea and cluster bean, demonstrating higher plant height, increased number of tubers per plant, elevated dry weight of shoots per plant, and enhanced dry weight of tubers per plant. Sunnhemp, with its substantial contribution to organic matter and nutrient content, positively influenced soil health, resulting in larger tubers and higher total tuber yield. Furthermore, nutrient management practices significantly impacted various growth parameters. The application of 100% recommended dose of fertilizer (RDF) along with farmyard manure (FYM) at 25 t/ha consistently led to superior outcomes, emphasizing the importance of balanced nutrition. The integration of sunnhemp as a green manure crop, coupled with 100% RDF + FYM 25 t/ha, demonstrated the most promising results, achieving higher plant height, increased tuber numbers, and elevated tuber weight.

The findings underline the intricate interplay between green manure crops and nutrient management practices in influencing potato growth and yield. The identified optimal combinations and practices provide practical insights for farmers aiming to enhance potato crop productivity sustainably. This study contributes valuable knowledge to the field of crop science, emphasizing the significance of tailored approaches for maximizing potato yield while ensuring soil health and environmental sustainability.
