Respons Tanaman Sorgum atas Aplikasi Mikoriza Arbuskula pada Gradien Konsentrasi N dan P

Sorghum [Sorghum bicolor (L.) Moench] is a multipurpose food crop that can adapt to climate change. productivity be increased by applying chemical fertilizers and arbuscular mycorrhiza fungi (AMF). This research aimed assess the effect of AMF application N P concentration gradients support Super 2 KS sorghum accession growth. The plants were grown in sterilized zeolite (coarse fine) inoculated with Glomus mosseae 40 spores per pot. experimental design was randomized complete block treatments three replications. gradient carried out using dose level fertilizer (urea) (TSP) at 12,5%; 50%; 75%; 100%; 125%. Analysis variance SAS 9.0 software 5%, results significantly different, followed DMRT. urea 50% TSP 75% accessions gave highest plant height biomass. However, increase growth did not correlate root colonization length, which could seen both obtained 12,5% 12,5%. lower use up compared positive control (urea 100%) accessions.
