Abstract

Production of cassava in Kalasan is still low. The problem faced is to improve cassava growth, thereby increasing cassava yields. The aim of this study was to determine the effect of mycorrhizal inoculation, stem wounding soaked in PGPR, and spraying nano EPOFB ash fertilizer on the growth of cassava plants. The demonstration plot for planting cassava in Kalasan field was arranged in a completely randomized block design (CRBD), with single factor treatments, namely: A = stem without wounding (control), B = stem with wounding and soaked in PGPR, C = stem without wounding and inoculated with mycorrhiza, D = stem without wounding and sprayed with nano EPOFB ash fertilizer, E = stem with wounding + soaked in PGPR + inoculated with mycorrhiza + sprayed with nano EPOFB ash fertilizer. The results showed that the application of the innovative technology package (stem with wounding + soaked in PGPR + inoculated with mycorrhiza + sprayed with nano EPOFB ash fertilizer) to cassava cultivation in Kalasan had an effect on the percentage of mycorrhizal colonization, increased the dry weight of the roots, and accelerated the emergence of large numbers of shoots, thereby producing the highest number of leaves despite the shortest plant height.
