Manure boosted vegetative growth and stigma yield (569.9 mg dry weight), while high-dose compost (CD3) enhanced flowering (+18%). Combined treatments showed balanced results but no synergy. Key soil challenges persisted: elevated pH and suboptimal organic matter (18.38%). Statistical analysis linked treatments to pH/limestone changes but not yield—likely due to field variability. Delayed planting and bulb-age imbalance reduced second-year productivity. Findings highlight the need for integrated organic strategies: acidifying amendments, optimized planting schedules, and rigorous soil monitoring to maximize saffron performance in arid zones.frsafran, biofertilisants organique, fumier, compost, sol, Ghardaïasaffron, organic fertilization, arid agriculture, soil amendments, sustainable farming
