An experiment was carried out to study the effect of type of cutting, IBA and bioinoculants on ischolar_maining in madhunashini. Among the three types of cuttings, hardwood cuttings registered higher values for fresh (0.790g/cutting) and dry weight (0.650g/cutting) of sprouts, per cent ischolar_maining (6.66 %), fresh and dry weight of ischolar_mains (0.037 and 0.030g/ cutting) and biomass production (0.682g/cutting). Among IBA and bioinoculant treatments, Azotobacter chroococcum recorded higher values for percentage sprouting (26.66 %) and ischolar_maining (9.99 %) as also for other ischolar_main parameters; whereas, maximum fresh weight (0.863g/cutting) and dry weight of sprouts (0.740g/cutting), and, biomass production (0.759g/cutting) was observed in IBA 1000ppm treatment. Interaction effect of type of cutting, IBA and bioinoculants on fresh and dry weight of sprouts (2.438g and 2.084g, respectively) and biomass production (2.123g/cutting) was found superior in hardwood cuttings treated with IBA 1000ppm. Percentage of ischolar_maining (13.33 %) was better in hardwood cuttings treated with Azotobacter chroococcum. Therefore, among the various treatments tested, hardwood cuttings treated with Azotobacter chroococcum are the best for propagation through cuttings.

Abstract


An experiment was carried out to study the effect of type of cutting, IBA and bioinoculants on ischolar_maining in madhunashini. Among the three types of cuttings, hardwood cuttings registered higher values for fresh (0.790g/cutting) and dry weight (0.650g/cutting) of sprouts, per cent ischolar_maining (6.66 %), fresh and dry weight of ischolar_mains (0.037 and 0.030g/ cutting) and biomass production (0.682g/cutting). Among IBA and bioinoculant treatments, Azotobacter chroococcum recorded higher values for percentage sprouting (26.66 %) and ischolar_maining (9.99 %) as also for other ischolar_main parameters; whereas, maximum fresh weight (0.863g/cutting) and dry weight of sprouts (0.740g/cutting), and, biomass production (0.759g/cutting) was observed in IBA 1000ppm treatment. Interaction effect of type of cutting, IBA and bioinoculants on fresh and dry weight of sprouts (2.438g and 2.084g, respectively) and biomass production (2.123g/cutting) was found superior in hardwood cuttings treated with IBA 1000ppm. Percentage of ischolar_maining (13.33 %) was better in hardwood cuttings treated with Azotobacter chroococcum. Therefore, among the various treatments tested, hardwood cuttings treated with Azotobacter chroococcum are the best for propagation through cuttings.
