Abstract

Introduction turfgrass varieties require fertilization with high dosage, but it can contaminate environment.  The increasing  efficiency of fertilizer absorbtion was expected to reduce fertilizer requirement.  The experiment was conducted to study the effect of arbuscular mycorrhizae and Azospirillum sp. on nutrient uptake, fertilization efficiency, growth and visual quality of turfgrass.  The experiment consisted of two factors, i.e. the dosages of fertilizer and inoculant types.  The dosages of fertilizer were the relatif dosage from recommended dosage (RD) i.e 100%RD, 75%RD, 50%RD, and 25%RD.  The recommended dosage was 0.5 kg N + 1.5 kg P2O5 + 0.5 kg K2O per 100 m2/month by compound fertilizer (15-15-15).  The treatment of 100%RD without inoculant was used as control.  The inoculant types were no inoculant, arbuscular mycorrhizal fungi (AMF), Azospirillum sp., and AMF+Azospirillum sp.  Factorial experiment was arranged in Randomized Block Design with three replications.  The results showed that interaction between inoculant type and dosage of fertilizer affected nutrient uptake, fertilizer efficiency, growth, and visual quality.  AMF inoculation and 25%RD increased shoot N uptake and N fertilizer efficiency, compared with control.  Azospirillum sp. inoculation at 75% RD increased shoot N concentration, but did not affect on shoot N uptake and N fertilizer efficiency compared with control.  Inoculant did not affect shoot P concentration, shoot P uptake, and P fertilizer efficiency.  Azospirillum and AMF+Azospirillum inoculation increased shoot K concentration.  AMF+Azospirillum inoculation and 100%RD increased shoot N concentration and shoot N uptake, compared with control.    Key words : Arbuscular mycorrhizal fungi, Azospirillum, fertilizer efficiency, nutrient uptake, turfgrass.

Abstract

The objective of the research was to evaluate the resistance of soybean genotype in the germplasm collection to pustule disease. Seventy five genotypes were evaluated using spray inoculation method. Inoculation was done on the third week after planting. The 75 genotypes evaluated consists of 29 local varieties, 8 national varieties, 23 introduction, and 15 experimental lines. Results of the experiment showed that among the 75 genotypes tested, one local variety, Si Pinang was found resistant to the pustule disease (Xanthomonas campestris pv. glycines). The resistant local variety was collected from Langkat, North Sumatra.
