| Abstract | ||
| Currently, there is an urgent need to use sustainable natural sources of potassium (K) to reduce reliance on chemical fertilizers without causing a significant decline in productivity . Therefore, a field experiment was carried out aiming to evaluate the efficiency of feldspar as a natural potassium source accompanied by potassium solubilizing bacteria (KSB) on garlic productivity as compared to other potassium mineral fertilizers. Seven potassium treatments [T1: 100% of Potassium Recommended Dose (KRD) from potassium citrate; T2: 100% of KRD from potassium sulphate; T3: 100% of KRD from potassium feldspar; T4: 80% of KRD from potassium feldspar +20% from potassium citrate; T5: 60% of KRD from potassium feldspar +40% from potassium citrate; T6: 80% of KRD from potassium feldspar +20% from potassium sulphate; T7: 60% of KRD from potassium feldspar +40% from potassium sulphate] were studied as main factor, while the KSB type [B.mucilaginosus, B.circulans and control] were studied as the sub main factor. Results showed that T1 and T2 treatments achieved the highest values of growth and productivity traits as well as the B.mucilaginosus recorded the highest improvements followed by B.circulans then control. As for interaction effect, it was noticed that both T1 and T2 treatments without KSB achieved non-significant values compared to the combined treatments of (T5 x B.mucilaginosus or B.circulans) and (T7 x B.mucilaginosus or B.circulans). Overall, integrating the soluble mineral potassium sources, natural sources i.e., feldspar and inoculation with KSB as an effective strategy to reduce reliance on synthetic fertilizers and improve the sustainability of garlic production. | ||
