Abstract:This research was conducted in the Abenggi of village, District of Landono, Regency of South Konawe, Province of Southeast Sulawesi and Laboratory of the Faculty of Forestry and Environmental Science Halu Oleo University Kendari, Indonesia took place from November, 2014 untill April, 2015. This study aims to determine the effect of mycorrhiza fungi from granssland and liquid organic fertilizer to the growth and yield of sweet corn on Ultisols Abenggi. This research is compiled using a randomized block design (RBD) with factorial pattern. The first factor are mycorrhiza fungi (M) with three levels: without mycorrhiza fungi (M 0 ), mycorrhiza as 20 g each planting hole (M 1 ), mycorrhiza as 40 g each planting hole (M 2 ) and second factor are liquid organic fertilizer (P) which comprises three levels of treatment: without liquid organic fertilizer (P 0 ) liquid organic fertilizer as 50 ml L -1 water each plot (P 1 ), liquid organic fertilizer as 100 ml L -1 water each plot (P 2 ). The combination of these two factors obtained 9 combinations of each treatment was repeated three times in order to obtain the amount of 27 experimental units. The observed variables in this study were plant height, stem diameter, cob weight with husk, corn cob without husk, cob length, cob diameter, number and percentage of mycorrhiza infection on the roots of the sweet corn. The results showed that the interaction between mycorrhiza fungi and liquid organic fertilizer has a significant effect on the plant height age 42 days after planting and cob weight without husk with the best results obtained in the treatment of mycorrhiza as 40 g hole -1 with liquid organic fertilizer as 50 ml L -1 water. Application the mycorrhiza fungi as 40 g hole -1 gives the best results on the growth and yield of sweet corn.
This research was conducted in the net house Sindang Kasih of village, District of West Ranomeeto, Regency of South Konawe, Province of Southeast Sulawesi and Laboratory of the Faculty of Forestry and Environmental Sciences Halu Oleo University Kendari, Indonesia. This study aims to assess the growth and potential of Ageratum conyzoides as host plant propagation of mycorrhiza fungi. This research is compiled using a Completely Design Block (CDB) with five treatments i.e.: without mycorrhiza fungi polybag −1 (A0), 10 g mycorrhiza fungi polybag −1 (A1), 20 g mycorrhiza fungi polybag −1 (A2), 30 gmycorrhiza fungi polybag −1 (A3), and 40 g mycorrhiza fungi polybag −1 (A4). Each treatment was repeated 3 times in order to obtain the amount of 15 experimental units. The observed variables in this study were the stem of diameter, the leaves number of weed, the leaves area of weed, the number of seed stalk, seed number, seed weight and percentage of mycorrhiza fungi infection on weed rootings. The results showed that all doses treatment of mycorrhiza fungi inoculated was affected on growth of A. conyzoides.
The research aimed to determine the effectiveness of compost containing humic and fulvic acids, and pure humic and fulvic acids in increasing of Ultisol soil chemical properties. The research design used a randomized block design (RBD), consisting of 10 treatments, namely K0: 0 g polybag-1, KO1: 500 g polybag-1, KO2: 500 g polybag-1, KO3: 500 g polybag-1, KO4: 500 g polybag-1, KO5: 500 g polybag-1, KO6: 500 g polybag-1, KO7: 500 g of polybags-1, H: 50 g of polybag-1, A: 500 g polybag-1. Each treatment was repeated three times and obtained 30 treatment units. The results showed that pH H2O (K0: 4.49, KO1: 5.64, KO2: 5.47, KO3: 5.43, KO4: 5.51, KO5: 5.39, KO6: 5.48, KO7: 6.17, H: 5.06, F: 5.15), total-N (%) (K0: 0.13, KO1: 0.17, KO2: 0.18, KO3: 0.30, KO4: 0.25, KO5: 0.24, KO6: 0.29, KO7: 0.36, H: 0.16, F: 0.14), organic-C (%) (K0: 1.85, KO1; 2.30, KO2: 2.24, KO3: 2.33, KO4: 2.62, KO5: 2.25, KO6: 2.27, KO7: 2.95, H: 2.32, F: 2.26) , available-P (%) (K0: 2.75, KO1: 3.24, KO2: 3.16, KO3: 3.27, KO4: 3.57, KO5: 3.31, KO6: 3.37, KO7: 3.89, H: 3.10, F: 3.12), exchangeable-Al (me100g-1) (K0: 2.51, KO1: 2.11, KO2: 2.13, KO3: 2.15, KO4: 1.88, KO5: 2.14, KO6: 2.12, KO7: 1.75, H: 2.16, F: 2.17), base saturation (%) (K0: 30.91, KO1: 63.48, KO2: 52.63, KO3: 53.76, KO4: 56.13, KO5: 54.96, KO6: 56.71, KO7: 65.53, H: 39.11, F: 42.76), cation exchange capacity (me100g-1) (K0: 12.76, KO1: 15.64, KO2: 14.86, KO3: 14.35, KO4: 14.13, KO5: 15.01, KO6: 15.50, KO7: 17.94, H: 14.19, F: 13.73).

This research aimed to study the propagation spores of arbuscular mycorrhiza fungi (AMF) on different host plants. This research conducted in completely randomized block design (CRBD) with factorial pattern and each treatment was repeated three times and each consist five pot cultures, the total of treatments are 150 pot culture. The first factor are: kinds of host plant (A) with five levels i.e.: Pueraria javanica (A1), Centrocema pubescens (A2), Sorgum bicolor (A3), Cajanus cajan (A4), Zea mays (A5) and second factor are mycorrhyza fungi (B) which comprises two levels i.e.: Glomus sp (B1), Acaulospora sp (B2. The result of research showed that the highest average of spores number on P. javanica + Glomussp as 38 spores and lowest on C. pubescens+ Glomus sp and Z. mays + Glomus sp respectively as 28 spores. The percentage of roots colonization for Glomus sp on kinds of host plant i.e.: P. javanica as 60.36%, S. bicolor as 47.93%, Z. mays as 35.36%, C. cajan as 21.72%, C. pubescens as 20.55%. The percentage of roots colonization for Acaulospora sp on S. bicolor as 39.83%, C. cajan as 27.98%, C. pubescens as 26.57%, P. javanica as 23.82%, Z. mays as 21.20%. The highest average weight of shoots and roots on treatment of P. javanica (A1) each 0.82 g and 0.91 g.
