摘      要：Efficient utilization of isabgol(Plantgo ovata Forsk.)straw biomass through preparation of bio-active organic fertilizer in a natural composting process has not been *** this study,phosphate rock and silicate mineral(mica)powder were used as natural sources of phosphorus(P)and potassium(K),*** dung slurry as a natural decomposer was mixed with the straw biomass at a 10:1(weight/weight)ratio along with mineral ***,nutrient-mobilizing bio-inoculants were used in the composting process after attaining thermal *** agronomic effectiveness of the resulting bio-active compost(BAC)as a bio-organic fertilizer was compared with that of conventional organics(farmyard manure and vermicompost)and chemical fertilizer(CF)by growing isabgol under field *** with the natural sources of P and K along with the bio-inoculants increased the total nitrogen(13.6 g kg^(-1)),P(38.7 g kg^(-1)),and K(31.2 g kg^(-1))contents in the final product(i.e.,BAC)compared with composting without the mineral powder and *** of BAC remarkably improved the seed yield(2.5%)and husk quality of isabgol in comparison with conventional organics and *** with CF,BAC significantly boosted the economic yield of isabgol by improving the husk recovery(2.5%)and mucilage yield(4.12%).Furthermore,BAC significantly improved the soil quality by increasing organic carbon(C),available nutrients,and microbial biomass C contents,as well as enzyme *** positive correlation between soil and plant parameters also highlighted the benefits of BAC for isabgol production through soil quality ***,it can be considered as a zero-waste technology,whereby a large quantity of straw biomass generated from isabgol cultivation,which contains essential nutrients,can be recycled back to the ***,BAC can be effectively used as a bio-active organic fertilizer,particularly in systems where chemical inputs are restricted,
