Agroforestry systems (AFS) are emerged to adapt with farmers needs, balancing economic andecological conditions. In recent years, however, there has been shifting from ecology to economy, wheretraditional silviculture emphasizes toward more monoculture with high inputs. This condition willresult in decreasing ecological function of AFS as one of the epitomes of sustainable. This research aimsto know the role of traditional silviculture techniques practiced by farmers and to develop knowledgein AFS management as the basis to compose more productive and sustainable management. Thestudy was conducted in Menoreh mountains, Yogyakarta. There zones based on altitude differenceswere distinguished, namely lowlands (<300 meter above sea level, masl), medium (300-600 masl) andhigh (> 600 masl). Data collecting was done by conducting deep interviews from 46 respondents, whowere chosen randomly in each zone. The data included local knowledge practices, space dynamic andmanagement, traditional silviculture, and orientation of AFS management.

Intercropping kayu putih (Melaleuca cajuputi) has more advantage than other tree crops, such as teak, pine or acacia due to the beneficial intercropping season length.Â Soybean was intercropped with kayu putih because soybean has higher commercial value than other field crops. The survey-based research was conducted during March until May, 2014 in Menggoran Forest Resort, Playen Forest Section, Yogyakarta Forest Management District. Stratified random sampling method was used during the research by stratifying the types of soil stratification (alfisol and vertisol), rainfall and declivity then was made into 7 land mapping unit (LMU) with map overlay technique. Agronomic characters of soybean were observed on 12 weeks after planting (wap) and the physiological data were observed during the maximum vegetative phase (8 wap). Agronomic and physiological characters of soybean in each LMU were grouped and statistically tested with analysis of variance (ANOVA) then continued with orthogonal contrasts (alpha 5%). The results showed that some characters of soybean planted in alfisol had higher value than in vertisol, especially on leaf area, photosynthetic rate, root and canopy weight, 100 grain weight and grain weight per plant. The agronomic and physiological characters of soybean which had significant effects on yield in the intercropping with kayu putih system were stomatal density, stomatal conductivity, photosynthetic rate, and leaf area. Soybean intercropped with kayu putih produced 1.007 tons/ha in alfisol and 0.996 tons/ha in vertisol. Soybean development in intercropping system of kayu putih can be conducted by using soybean varieties superior effort.

Rice production can be improved through extensification using sub-optimal lands. One type of land that can be used for extensification of rice production in D.I. Yogyakarta is eucalyptus agroforestry system in Playen, Gunung Kidul. Besides expanding the land use, it can also increase farmersâ€™ income and ecological functions. However, this system has limiting factors such as the limited availability of water, which only relies on rain. Thus, proper water management and fertilization are necessary to fulfill water and nutrient requirements for rice growth. This study aimed to determine the effects of the application of trenches with organic matter and the doses of KCl on the growth and yield of upland rice (Situ Patenggang) in eucalyptus agroforestry systems. The study was conducted at the Menggoran Forest Management Resort, Bleberan, Playen, Gunung Kidul in March-August 2018. The study was arranged in a split-plot design with three blocks as replications. The first factor was the application of trenches with organic matter, while the second factor was KCl fertilizer at. various doses. The data obtained were analyzed using analysis of variance (ANOVA) at the level of 5%. The optimal dose of KCl fertilizer was determined by regression. The results showed that both factors had a positive effect on soil moisture content, growth, physiology, and yields of upland rice. The treatments significantly increased the availability of water in the soil, thereby supporting the growth and yield of upland rice.

The land ownership of smallholder private forest farmers is relatively narrows, so some reseachersargue that the forest product is not appropriate to fulfill daily needs. To increase and spread the privateforest management risk, farmers diversify crops into several species. In order to identify the farmerstrategy through optimizing the land, we developed household survey for 90 respondents from 3villages in Batur Agung zone, Ledok Wonosari zone and Pegunungan Seribu zone. The survey resultsshowed that private forest utilization by agroforestry is a type of local wisdom, as farmers ‘strategy tofulfill the farmers’ need. Private forest contribution toward total income in Gunungkidul is 13-40%. Thebiggest contribution for farmer in Batur Agung zone and Ledok Wonosari is from trees (59-61%), whilefor farmer in Pegunungan Seribu is from crops (59%).

Biochar is used to improve soil fertility and control nitrogen loss in soil. This study aimed to evaluate the difference between biochar sources, namely Melaleuca cajuputi waste and rice husk, for controlled nitrogen loss in hybrid maize planted between Melaleuca cajuputi stands. A split-plot design with three replications was used. The main plot was composed of biochar sources (BS), i.e., without biochar application (WB), Melaleuca cajuputi biochar (MCB), and rice husk biochar (RHB). The subplot was the urea fertilizer dosage, i.e., 0, 150, 300, and 450 kg/ha. The observation parameters were nitrate reductase activity (NRA), total chlorophyll (TC), leaf photosynthesis rate (LPR), nitrogen loss (NL), nitrogen use efficiency (NUE), and seed yield per hectare (SY). The data were analyzed with ANCOVA and LS-means. The results showed that there was no significant difference between mixing MCB or RHB in UF for all hybrid maize parameters, whereas significant differences were observed with WB. The NL values of MCB and RHB were 13.85 and 13.08 kg/ha N, i.e., NL was significantly reduced by 70.90% and 72.51%, and the percentage of SY increased by 28.60% and 37.94% compared to WB, respectively.

Bugel coastline areas have the potential for horticulture commodities development. This study's objectives were mapping protected Bugel coastline areas, land evaluation, and yield response of chili in an agroforestry system with coconut trees on Bugel coastline areas. The research was conducted during April-July, 2015, in Bugel coastline areas, Panjatan District, Kulonprogo Regency, Special Province of Yogyakarta. The first stage was the literature study and field mapping by BING satellite imagery. The second method was an actual and potential land evaluation using the FAO version, Sys criteria, and Sys limitation. The third method was using a randomized complete block design (RCBD) with three blocks as replications. The results showed that a local protected coastline area allowed for the agriculture and forestry crops is >200 meters from the furthest tide point. The actual and potential land evaluation in all agroforestry phases were not suitable and marginally suitable. The initial phase showed the highest fresh fruit weight by 100.30 grams/plant, compared with the intermediate and advanced phases by 88.13 grams/plant 71.54 grams/plant.
