Abstract

The efforts to improve the productivity of soybean can be done through technological innovation by the provision of chemical fertilizers and mycorrhizae. This study were aimed to obtain information on the effect of a single fertilizer, which can provide the same or higher level of soybean crops if compared with those compound fertilizers, as well as to find out the effect of mycorrhizae to the improvement of efficiency in the use of inorganic fertilizers. It is expected that the mycorrhizae inoculation can reduce single fertilizer’s dose to the level equivalent to the compound fertilizer given by farmers. The study was conducted in Bleberan Village, Playen Subdistrict, Gunung Kidul Regency, Yogyakarta from February to May 2015. It was conducted by using a two-factors factorial design arranged in a randomized block design with three replications. The first factor was inorganic fertilizer (N, P2O5 and K2O), consisting of 5 levels, i.e. without fertilizer (0-0-0 kg/ ha), Phonska fertilizer (45-45-45 kg/ha), single fertilizer (45 -45-45 kg/ha), a low single fertilizer (23-36-30 kg/ha) and high single fertilizer (23-108-90 kg/ha). The second factor was mycorrhizal inoculation, consisting of three levels, i.e. without mycorrhizae (0 g), medium dose (2.5 g) and high dose (5 g). Data were analyzed using Analysis of Variance (ANOVA) at a significance level of 5%. If there was a significant difference, analysis was followed by Duncan Multiple Range Test with a significance level of 5%. The relationship between variables observed was examined by a correlation analysis. The results showed that there was no interaction between inorganic fertilizer and mycorrhizal application. The dose of single fertilizer which was equivalent to the dose of compound fertilizer given to soybean could increase crops by 1.37 t/ha compared with plants treated with a compound fertilizer 1.13 t/ha. The results of correlation analysis among parameters showed that there were correlations between the grain crops and height (r = 0.506**), stem diameter (r = 0.303*), and the number of pods per plant (r = 0.313*).

Abstract

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 (&lt;300 meter above sea level, masl), medium (300-600 masl) andhigh (&gt; 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. The analysis itself was donedescriptively which was integrated through diagnosis approach and design in agroforestry systems.There are there models of AFS management based on there strata of space utilization both in homegardenand dry field, namely initial, intermediate and advanced agroforestry. In the lowland zone is initialagroforestry practicw, characterized by food production orientation. In the middle and upper zone areintermediate and advanced Based on this findings, aproductive and sustainable adaptive silviculture(AS) scheme for AFS management (AS AFS) is required, AS AFS_1 is oriented to keep agroforetybeing able to continualy produce food and its derivatis throughout the management. Intensive spacearrangements and resources sharing silvicuculture measures are important instruments in this model.The second model, AS AFS_2 is for productive intermediate and advanced agroforestry with multilayerproductions. It is suggested in this model to do intensive enrichment planting using tolerant species andcompatible management approach of inter unit lands owned by farmers.

Abstract

It was necessary to obtain optimum dose of nitrogen, phosphorus, and potassium obtained through fertilisation in order to improve productivity in the intercropping. Kayu putih tree was cultivated in Yogyakarta for oil production, and the inter-row was designed for intercropping plants, including soybean. The objective of present study was to obtain optimum dose of urea, SP-36, and KCl for soybean intercropped with kayu putih. The experiment was conducted in Menggoran Forest Resort (RPH Menggoran), Playen Forest Section (BDH Playen), Yogyakarta Forest Management District (KPH Yogyakarta) using split-split plot design. The main plot was urea, subplot was SP-36, and sub-subplot was KCl. Fertilisation consisted of three levels (0, 25, 50 kg ha-1 of urea), (0, 150, 300 kg ha-1 of SP-36) and (0, 75, 150 kg ha-1 of KCl). The results showed that application of 50 kg ha-1 urea, 300 kg. ha-1 SP-36, and 150 kg. ha-1 KCl increased N, P, K uptake per hectare as much as 16.23 kg N ha-1, 86.27 kg P ha-1, 40.02 kg K ha-1, respectively. There was positive interaction between urea and SP-36, SP-36 and KCl at leaf area, photosynthetic rate, number of seeds per plants, seed weight per plants, and seed weight per hectare. Under kayu putih intercropping, optimum dosage of urea, SP-36 and KCl were 0, 298.03 and 87.12 kg ha-1, respectively. These combination enabled to produce maximum seed weight of 2.01 tons. ha-1.
