The effects of biochar and chicken manure on the growth and yield of pea in sandy soil
الملخص
Pea (Pisum sativum L.) is an herbaceous annual plant in the Fabaceae family, known for its cultivation over millennia as a vital food crop worldwide. However, the influence of biochar on its production under organic farming conditions remains inadequately explored. This study investigates the synergistic effects of biochar and chicken manure on the growth and yield of pea plants. The experiment employed a completely randomized block design (CRBD) with three replicates, encompassing four treatments: a control, 10 t/ha chicken manure, 2 % biochar combined with 10 t/ha chicken manure, and 5 % biochar combined with 10 t/ha chicken manure. The experiment was conducted in the winter of 2023. The results revealed that the biochar-chicken manure combination significantly enhanced pea growth and yield. Notably, the 5 % biochar plus 10 t/ha chicken manure treatment achieved the highest increase, boosting yield by 70 % compared to the control. These findings highlight the potential of biochar as a potent amendment in organic farming, especially in challenging soil conditions like sandy soils. Future research should delve deeper into the long-term impacts of biochar on soil health and pea productivity to refine sustainable agricultural practices.
