| Summary: | The purpose of this study is to investigate infectivity and effectiveness of V AM fimgi for 81J8&rCane varities, the influence of V AM inoculation to the sugarcane growth in phosphor scarcity soils, the influence soil inoculmn amotmt of VAM fungi to the sugarcane growth and also the effect ofVAM inoculation and TSP fertilizier dosll8e application to the trug111"Cano yiold, sugarcane oontont, and orystal sugar.
The experiment was conducted in Complete Randomized Design (pot experiment) and Randomized Block Design (field experiment). The parameters observed were agronomy components and yield production. The difference between treatment8 were teated by HSD (Honestly Significance Difterence) 5 %. The results showed that the infectivity of Indigenous V AM and Glomus sp were higer than.Acaulospora sp. The Indigenous VAM have high effectiveness on M 442-Sl cane variety for P concentration in le~ per~entage of root infected, and
shoot dry weight, whereas Glomus sp has high effectiveness for P concentration in leaf on M 442-51, Ps 61, and Q 90 cane varities. Myconbizal treatments significantly affected cane height In inceptisol soil,
Indigenous VAM , Glomus sp, and .Acaulospora sp increased cane height in the amotmt of 11.75%, 9. 20%, and 7 .900A,, while in oxisol 'oil that ia 16.71%, 24.65%, and 22.77%. The height of cane and persentage of root infected respon&e was as high as 300 gram soil inoculmn were applied and inoculation with 358.60 gram aoil inoculmn can be obtained maxiunun moot dry weight. The V AM inoculation can either increase cane yield at a given level of applied P, or reduction of the P application level. Inoculated with Indigenous V AM can be reduced TSP fertilizier application in the amotmt of28.19 %, while Glomus sp 41.75%. |
