Abstract

A field experiment was conducted in accordance with Completely Random Block Design (CRBD) and three repeats at the University of Baghdad/ College of Education for Pure Sciences (Ibn Al-Haitham) during 2020-2021 to evaluate the effect of nano NPK nano-fertilizer with concentrations (0.5, 0.7, 1 ml.L-1) with control treatment (without any addition) and second treatment a combination of bacterial fertilizer; Bacillus mucilaginosus, Bacillus megaterium, Rhizobium and Azotobacter chroococcum with two concentrations (107,109) C.F.U gm-1 dry soil with control treatment (without any addition) with two varieties of fenugreek plant (Indian and local). Results showed that the addition of the nanofertiliser treatment mixture exceeded the concentration of 0.75 ml.L-1 and the combination of the biofertilizer 109 C.F.U gm-1 dry soil with the local variety fenugreek plant significantlly in the wet weight of the vegetative total (38.526 gm.plant-1) compared to the control treatment (without addition). The results also showed that the treatment of adding a nanofertiliser treatment mixture exceeded the concentration of 0.75 ml.L-1 and the combination of the biofertilizer 109 C.F.U gm-1 dry soil with the fenugreek plant (local) significantlly in the dry weight of the vegetative total (15.102 gm.plant-1) compared to the control treatment (i.e. without addition).
