Abstract

Organic rice cultivation rely only source of nutrients of organic fertilizers and other natural inputs. One way to meet the needs of nitrogen in organic rice cultivation is to utilize the organic fertilizers. The purpose of this study was to examine the influence of the type of organic fertilizers on N-available content in the soil, the characterization of the pattern of mineralization of N-available from types of organic fertilizer, and determine the three types of organic fertilizer which has a pattern of fast nitrogen mineralization, medium and slow. This research was conducted through experimental methods in greenhouse Faculty of Agriculture of Gadjah Mada University from November 2012 until May 2013. Experiments using randomized completely design (RCD), consisting of 1 factor and 3 replications. These factors is incubation organic fertilizer in soil organic lowland, consisting of 10 types: Callyandra callothyrsus, Leucaena leucocephala, Sesbania grandiflora, Albizia falcata, Cassia siamea, Gliricidia sepium, Samania saman, Herocarpus indica, manure, and control (without organic fertilizer). The results showed that the use of organic fertilizers can improve the content of N-available in the soil as compared to manure and without organic fertilizer. In general, the pattern of nitrogen mineralization of organic fertilizers on soil organic lowland started 3 weeks after incubation and increased up to 9 weeks after incubation, and then decreased 12 weeks after incubation period. Sesbania grandiflora, Gliricidia sepium and Leucaena leucocephala, respectively, have the character pattern nitrogen mineralization fast, medium and slow.Keywords: organic fertilizers, N mineralization, soil organic lowland

Abstract

Penentuan jenis tanaman pangan yang sesuai ditanam pada lahan tertentu berdasarkan nilai-nilai karakteristik lahan sangat diperlukan sebagai pendukung pengambilan keputusan, koordinasi, dan pengendalian bagi para peneliti, praktisi, dan perencana penggunaan lahan, sehingga kerugian (finansial) yang cukup besar tidak terjadi nantinya. Program komputer dengan menggunakan Jaringan Syaraf Tiruan (JST) metode Learning Vector Quantization (LVQ) dapat digunakan sebagai alat yang tepat dalam memberikan informasi tanaman yang cocok ditanam dengan mudah, cepat, dan akurat. Data pelatihan didapat dari kombinasi nilai karakteristik lahan yang termasuk dalam kelas kesesuaian S1 dan S2. Hasil pengujian menunjukkan bahwa nilai Eps (error minimum yang diharapkan) = 0.005, nilai ?? ?? = 0.05, nilai maksimum epoh = 10, dan nilai pengurangan learning rate sebesar 0.1*?? ?? merupakan nilai-nilai yang cukup efektif dan efisien dalam melakukan prediksi jenis tanaman pangan yang sesuai ditanam pada lahan tertentu karena tingkat ketepatan prediksinya adalah 100%.

Abstract

Percobaan di rumah kaca telah dilaksanakan di provinsi DIY pada bulan Maret-Juni 2009. Percobaan bertujuan mengkaji tanggap fisiologis dan hasil bawang merah terhadap kondisi lengas tanah berbeda pada ketinggian tempat berbeda. Penelitian disusun berdasarkan percobaan lokasi dalam Rancangan Petak Petak Terbagi (Split Split Plot Design) diulang tiga kali. Petak utama adalah lokasi dengan ketinggian tempat berbeda di atas permukaan laut (dpl.) terdiri atas: (1) 100 m dpl., (2) 400 m dpl., dan (3) 800 m dpl.; Sub-plot adalah varietas bawang merah terdiri atas: (1) ‘Palu’, (2) ‘Palasa’, dan (3) ‘Sumenep’. Sub-sub-plot adalah lengas tanah dalam persentase kapasitas lapangan (% KL) terdiri atas: (1) 50% KL, (2) 100% KL, dan (3) 150% KL (kondisi jenuh). Lokasi dengan ketinggian tempat berbeda memberikan tanggap fisiologi dan hasil bawang merah yang berbeda. Varietas Palu memiliki aktivitas fotosintesis lebih besar pada semua kondisi lingkungan berbeda dan lebih tahan terhadap cekaman kekurangan dan kelebihan lengas tanah terutama di dataran rendah. Lengas tanah 100% KL menghasilkan aktivitas fisiologi dan hasil umbi kering panen lebih tinggi, sebaliknya lengas tanah 50% KL dan 150% KL menurunkan pertumbuhan dan hasil bawang merah varietas Palasa, Palu dan Sumenep pada semua ketinggian tempat.Kata kunci: bawang merah, ketinggian tempat, lengas tanah, fisiologi

Abstract

Foot rot disease epidemic on black pepper in variety of environmental conditions. The foot rot disease on black pepper caused by Phytophthora capsici Leonian, is often destructive to farmers of black pepper. This research aims to study the infection rate and the pattern of development of the black pepper foot rot disease in various condition of the environment. The research was conducted in the areas of black pepper cultivation in the Ultisol and Entisol soils. In each location plots were set with few (<25%) and abundant (>75%) weeds. Variable observed was disease incidence. The data were used to analyze model of development of the black pepper foot rot disease and infection rate. Results of the research showed that the model of development of the black pepper foot rot disease was not affected by soil type, but the type of soil affected the infection rate. At the pepper plantation with abundance of weeds, the disease development followes Gompertz model. At the plantation with few weeds, however the disease developed in a logistic model. The rate of disease infection on the black pepper plant with abundant weeds lower compared with those with few weeds.

Abstract

The experiment was conducted on the Technical Irrigated Rice Field in D.I. Yogyakarta with soil type is Regosol. The study took place in July to December 2010. The research aim was to obtain agronomic characters and optimal planting distance that could increase the productivity of land with furrow irrigation system (FIS). The research used a factorial design (2 x 4+2) with 3 replications. Factor 1 was cultivars (K): K1 (Cimelati) and K2 (Sarinah). Factor 2 was planting distances (J): J1 (20 x 20 cm), J2(20 x 15 : 40 cm; legowo 2:1), J3(20 x 12,5 : 40 cm; legowo 2:1), and J4(20 x 12,5 : 45 cm; legowo 2:1). Controls were Cimelati and Sarinah cultivars grown in wetland rice field. The experimental results showed that the ability of plants to form seedlings in FIS was better than in the rice fields. The ability of plants to form seedlings in FIS at different planting distances was similar. Net assimilation rate (NAR) and relative growth rate (RGR) in the wetland system was better than FIS, but the leaf area index (LAI) and crop growth rate (CGR) was better in FIS. The NAR, RGR, and CGR in both systems were similar. Larger panicle and grain panicle number, 1000 grain weight and percentage of filled grain rice were found in FIS than in the rice field. The growth of rice in FIS was not affected by differences in both cultivars and planting distance. Dry harvested grain weight in FIS was lower than in the rice field. Dry harvested grain weight of Cimelati cultivar (8.04 t/ha) in FIS with planting distance of 20 x 12,5 : 40 cm (legowo 2:1) was comparable with that in the rice field (8.05 t/ha).
