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

Drought is one of the major limitations in dry land cultivation. Drought affects plant physiology processes such as photosynthesis, respiration, mineral and water transportation, and transpiraton, briefly called drought stress. Drought stress can be avoided by managing environment. Furrow containing organic matter for rain fed rice has been the subject of many studies, with special emphasis on soil moisture. This research is aimed to know the effects of the furrow containing organic matter on physiological responses of several upland rice varieties on agroforestry system based on kayu putih (cajuput). The experimental design applied the strip plot design. The vertical factor is the furrow system of treatment consisting of 2 levels i.e. without furrow + without organic matter and furrow + organic matters. The horizontal factors are the upland rice varieties consisting of 3 varieties i.e. Situ Patenggang, Situ Bagendit and Ciherang. The collected data were analyzed by Analysis of Variance (ANOVA) applying a level of significance α = 5%. Whenever significant differences among treatments were found, further analysis was carried out by applying the Tukey's HSD (Honestly Significant Difference) test α = 5% levels. The result shows that drought affects plant physiology and can be avoided by using furrow containing organic matters. Situ Patenggang with furrow containing organic matters has the higher physiology capability, it had photosynthesis 387.18 µmol CO2 per clump s-1, transpiration 3038.50 mg per clump per secondand CO2 721.11 mol CO2 clump per mol. There different plant requirements for Cu between varieties.

Abstract

Modifikasi pemanfaatan lahan memiliki dampak baik ekonomi maupun ekologi. Perlindungan terhadap keanekaragaman hayati menjadi pusat perhatian dari sisi ekologi sementara pemanfaatan lahan demi produktivitas dianggap sebagai solusi ketahanan pangan. Serangga berada di dua isu tersebut yaitu konservasi dan ketahanan pangan. Penelitian ini bertujuan untuk mengetahui struktur komunitas serangga berdasarkan pada peran mereka dalam tingkatan trofik pada tiga tingkat perkembangan agroforestri (AF) jati yang berbeda (awal, tengah, lanjut). Pengambilan data dilakukan di Nglanggeran, Gunungkidul, Yogyakarta sepanjang musim kemarau (April, Mei, dan Juni 2016). Metode koleksi serangga yang digunakan adalah sweep net, pitfall dan sticky trap yang ditempatkan pada petak ukur (PU) 20 x 20 m2. Petak ukur dibuat dan diletakkan secara purposive pada masing-masing tingkatan AF. Total terdapat 8 PU yang terdiri dari 3 PU untuk tingkatan AF awal dan tengah, serta 2 PU untuk AF lanjut. Serangga yang tertangkap bervariasi berdasar pada tingkat perkembangan agroforestri dan bulan pengamatan. Terdapat perbedaan keragaman serangga (jumlah dan jenis) berdasarkan perbedaan tingkatan agroforestri (awal, tengah, dan lanjut) pada lahan lahan agroforestri berbasis jati di Desa Nglanggeran, Zona Batur Agung, Gunungkidul. Agroforestri awal dan tengah menunjukkan kemelimpahan serangga (ordo) terbanyak dengan proporsi tertinggi serangga yang berperan sebagai hama berasal dari ordo Lepidoptera, Diptera, Blattaria, Hymenoptera, Orthoptera, Coleoptera, Isoptera, dan Dermaptera. Tingkatan AF berpengaruh terhadap kehadiran serangga dari ordo Hymenoptera dan Diptera, lebih lanjut keragaman vegetasi pada agroforestri (awal dan tengah) dapat meningkatkan keragaman serangga baik yang berperan sebagai hama (trofik 2) maupun musuh alami (trofik 3).Kata kunci: agroforestri; hama; jati; serangga; trofik Insect Abundance and Its Structure Trophic Level on Different Level of Teak-Based Agroforestry Development at Nglanggeran Village, Gunungkidul District, YogyakartaAbstractModifications of land use have the economic and ecological implications. Protection upon biodiversity has been the center of concern on ecological side, while productivity of the land use has been considered a solution for food security. Insects are between these two major issues, namely conservation and food security.This study was aimed at tracing the structure of insect community based on its role on the trophic level on three different phases of teak-based agroforestry systems (early, middle, and advanced). The data was obtained in the area of Nglanggeran, Gunungkidul Regency of Yogyakarta during the dry season (April, May, and June 2016). Further, method of insect sample inventory utilized sweep net, pitfall trap, and sticky trap placed on measured area of 20 x 20 m2. The plots were placed purposively on each of agroforestry land, with the total of 8 plots, consisting of 3 areas of early and middle levels of agroforestry land, and 2 for late phase. Catched insects varied according to agroforestry growth and observation time. This research suggests that insect’s variety (abundance and morphospecies) is found based on agroforestry levels (early phase, middle phase and late phase) on observed teak agroforestry land in Nglanggeran Village of Batur Agung Zone, Gunungkidul. Early and middle agroforestry showed an abundance of insects (order), in which the largest proportion of them is categorized as pest (Lepidoptera, Diptera, Blattaria, Hymenoptera, Orthoptera, Coleoptera, Isoptera, and Dermaptera). The growth level of agroforestry has a direct impact on the presence of insects of Hymenoptera and Diptera orders. Furthermore, the variety of vegetation in early and middle agroforestry could increase the variety of insects functioning as either pest (trophic 2) or natural predators (trophic 3).
