Organic cultivation in egroforestry system by biofertilizer potentialy conducted for soybean. Soybean cultivation in agroforestry system there are several limitations but it have to effort since the area of ideal land decreasing year by year. The aim of the research by experiment method is increasing yield of soybean by organic cultivation in agrofrestry system either quality or quantity. The experiment design is randomized block design (RBD) with two factor trearments. The first factor are kinds of variety (Grobogan and Local) as mainplot and the second one are biofertilizer duration (no biofertilizer as control, 4, 5, 6, 7 weeks applies ones a week). So there are 10 combination treatments and replicated three times for each of them.

Garlic is one of the important horticultural crops in Indonesia so that the needs increas from year to year. In Indonesia plant material (seed) for cultivating garlic always uses comsumption bulb. The impact of that technique in a long time that the yield gradually decrease by virus infection from preliminary crop. The aim of the research was to find out of seed plant material which virus free by in vitro propagation technology. Acclimatitation is one of succesfuly determination in invitro propagation. Research by the experiment was to study the ability of New Tawangmangu, Gunung Kidul, and Bali garlic varieties on acclimatitation in several light intensity (by paranet shading). The results showed that the totipotency of the garlic varieties was high but in acclimatitation by the shading technique just survived two weeks only. The failure of acclimatitation was range of temperature 12-37°C.

Garlic potential in Indonesia to be low because the tubers as planting materials have been infected virus. Tissue culture generates plant virus free so the tuber production as healthy planting material. The role of media to the succes of tissue culture is very high. Although the available tissue culture media has nutrients contain, but for the growth of onion plantlets required additional nutrients such as yeast extract. Yeast extract contained enzyme, amino acids and vitamin needed by plant growth. The research aimed to study the effect of yeast extract on garlic plantlet growth in tissue culture. The use of yeast extract in tissue culture with MS medium for garlic explants does not increase the growth plantlet.

Turmeric is a medicinal plant that has largest secondary metabolites (curcumin). Improving secondary metabolites with abiotic stress that the provision of shade and water stress. This research aims to study the effects of shade and water stress on growth and yield of turmeric and content of secondary metabolites. The study uses a nested design with two factors, namely shade (without shade, 25%, 50%, 75%) and water stress (without stress, 25% field capacity, 50% field capacity, 25% field capacity). Analysis using the F test and DMRT 5% level. The results showed that shade did not effect to fresh and dry weight of plant. 75% shade decrease root lenght, fresh and dry weight of rhizome. Water stress did not effect to growth and yield of turmeric. The highest curcumin results in conditions without shade and without stress.

Homegarden is one alternative that multipurpose agricultural land to cope with reduced land resources. This study aimed to determine the characteristics of the ecology, species diversity and potential of trees in the homegarden that is useful in further development. The research had been conducted in June to August 2011 in the Kebak Village, Jumantono District, Karanganyar Regency with a altitude of 330 meters above sea level and soil type alvisol. This experiment used survey methods with observation unit is divided into three categories based on the size of the homegarden: narrow (<700 m2), medium (700-900 m2) and large (> 900 m2). Observed variables include three aspects: biological variables (type and number of trees, tree height, trunk diameter and canopy area), physical variables (analysis of soil, microclimate homegarden, macroclimate and physiographic land) and analysis of the vegetation (density, frequency, dominance, relative density, relative frequency, relative dominance, importance value index and the index of species diversity). Kebak village had been 40 species of trees are divided into fruit trees, timber, vegetable producers, growers and others. The results showed indicate that the type of fruit tree had the largest of 20 species by the reached 142 tree to rambutan tree. Spacious homegarden area had the highest type and number of trees as well as the highest species diversity index.

Temulawak (Curcuma xanthorrhiza) is one of superior kind of plant which has many benefits as medicinal plants. Cultivation of temulawak not yet intensively and grown on the land under the trees. Therefore, this research was important to get shade and water stress levels appropriate for cultivation of temulawak and higher producing secondary metabolities. This research used a nested design with two treatment, that is shade (without shade, 25%, 50%, 75%) and water stress (without water stress, 75%, 50%, 25% field capacity) with five replicants. Result were analyzed using analysis of variance and if there significant diference followed by DMRT 5% level. The result showed without shade treatment increase growth of temulawak include number of leaves, fresh weight of plant and dry weight of plants, and shade 50% increase plants height. The treatment of without water stress increase growth and yield of temulawak include number of tillers, number of leaves, fresh weight and dry weight of plants, fresh weight and dry weight of rhizomes. The levels of curcumin increase on shade 25% and water stress 25%.

Soybean is one of the most important food commodities in Indonesia and also it has high value. The needs continue to increase each year, but not offset by increased production become an issue that must be addressed. One attempt to increase soybean production is through the cultivation in agroforestry systems through improving the quality of soil fertility. This research aims to study the effect of various doses of litter teak and NPK fertilizer on chemical soil fertility and the potential of soybeans yield in agroforestry systems based teak crops. Experiments using a Randomized Complete Block Design (RCBD) with two factors, namely litter teak doses (0 ton ha-1, 2.500 ton ha-1, 5.000 ton ha-1, 7.500 ton ha-1) and doses of NPK fertilizer (60-60-60 and 60-120-60) on Grobogan soybean varieties. The variables measured were pH, organic matter content, N-total soil, cation exchange capacity (CEC), plant tissue of N, P-total soil, and component production. Data analysis using analysis of variance F-test based on the level of 5% and significantly different variables followed by Tukey’s method level of 5%. The results showed that combination treatment with various doses of teak litter NPK fertilizers can increase total nitrogen content of the soil with the highest yield of 1.69% on S1D2 treatment, but to organic matter, CEC, pH, and total soil P not significant effect. Component of soybean varieties of the highest Grobogan of 0.83 tons ha-1 in the treatment S1D1. The result was still below the average of the national soybean production.
