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

TITLE : EFFECT OF ARBUSCULAR MYCORRIZHAL FUNGI INOCULATION ON GLOMALIN, GROWTH AND RICE YIELD. The aim of this study was to measure the glomalin production, growth and yield of rice in upland rice fields. The research used Completely Randomized Design with four treatments: two sterilization levels (no sterilisatio and with sterilization) and two levels of mycorrhizae inoculation ( no mycorrhizae and with mycorrhizae). Mycorrhizae (5 g/pot) was inoculated before planting rice seeds. The results showed that Glomalin Total (GT) and Glomalin easily extracted (GEE) were higher in mycorrhizae inoculation, increased by 16% and 20% in non-sterile soil and 25% and 11% in sterile soil compared to non-mycorrhizae inoculation. The content of the GT ranged from 4.95 to 9.74 mg/g soil and GEE 0.99 to 2.78 mg/g soil. Plant height, tillers number and  the  grain yield was increased by mycorrhizae inoculation significantly. Soil sterilization could reduce the effectiveness of mycorrhizae inoculated.

Abstract

Title : Study of Critical Soil Conservation Based on Land Unit on Sempor’s Catchment Area, Kebumen Regency. This research  aims to predict critical soil and soil erosion  level of Sempor’s  Catchment Area and to recommend the management according to soil conservation.This  is  an  explorative  descriptive  research  based  on  environment  data.  The  data  are obtained from field observation and result of laboratory analysis of soil samples taken from field survey. Furthermore, the data are classified based on critical soil classification to get critical soil map. The data also are calculated based on USLE to get soil erosion prediction. The results of soil erosion prediction are grouped based on erosion hazard levels and result of soil erosion mapping. After knowing  critical soil and soil erosion level in each land unit, recommendation  is made to manage land according to soil conservation.The result shows that on observation area with total extent 4,333.68 ha there are criticalsoil about 1,373.68  ha (31.70 %), semi critical about 2,164.54  ha (49.95 %), potentially  critical about 440.46 ha (10.16 %) and the others are about 355.00 ha (8.19 %) in the form of settlement and  reservoir  located  at  the  outside  of  the  observation  area.  The  soil  erosion  predicted  on observation area are divided into 6 classes, those are very low erosion class at about 103.90 ha (2.40 %), low erosion class at about 332.00 ha (7.66 %), moderate erosion class at about 953.78 ha (22.01 %), high erosion class at about 247.53 ha (5.71 %), very high erosion class at about 2,108.50 ha (48.65 %), acute erosion class at about 232.96 ha (5.38 %) and the others are out of observation  area. Topography  and land management  are factors that have the most dominant influence to soil erosion prediction. Total soil erosion on observation  area is about 320,958.016 tons/ha  or soil erosion average  about 74.061 tons/ha/year.  The recommendation  is to restore critical and erosion through some actions such as reboization or planting with annual crop, vegetation nursery, adding organic matter via organic fertilizer or organic mulches, making and maintaining of terrace and ditches, and agroforestry.Keywords: critical soil, erosion, Sempor,  soil coservation

Abstract

The use of high organic fertilizer in the organic farming system is one of the obstacles in the implementation of organic farming in Indonesia. It is necessary to find alternative materials to substitute or meet the shortage of existing organic fertilizer. This study aims to determine the effect of Azolla (Azolla mycrophylla. L) on some soil chemical properties on organic paddy field. The The field experiments used factorial complete randomized block design of three factors, namely Azolla (0 and 2  tons / ha), Manure (0 and 10  tons / ha) and Rice Varieties ( Mira1, Mentik Wangi and Merah Putih), with three times replication.  Azolla  2  tons / ha is able to increase soil total  N 18%; available P  87,5 %; organic C  3,78% CEC 8,03 % and soil pH 1,00%;  compared to control (without Azolla). Compared with manure 10  tonss / ha, giving Azolla 2  tonss / ha was able to increase only on soil available P about 50 %, but lower on  soil total N, organic C, CEC and  soil pH  1,9% ; 9,27% ; 9,40% and 0,67%.  Azolla can be used as a substitute or complement  of manure on organic  paddy field.

Abstract

Phytophthora capsiciis a causal agent for footrot disease in pepper and classified as a soil-borne pathogen. The inoculums of P. capsici in the soilis difficultto detect. The dynamics of P. capsici population in the soil is frequently and rapidly fluctuates and hard to detect, causing the pathogen to produce disease rapidly. The aimsof this research were todetect the pathogen P.capsici using black pepper leaf baiting and to quantify the inoculum of the pathogen P.capsici in the soil belonging to several disease intensities of the black pepper foot rot in the field. The first experiment: detecting the pathogen P. capsici using black pepper leaf baiting in the soil artificially infested using several sporangia, anda second experiment: quantification of propagul of the P.capsici in various categories of intensity on the black pepper foot rot disease in the field. The research results showed that the black pepper leaf baiting could be used to detect the existence of the propagul of P.capsiciin the soil artificially infested in various densities of sporangia.  The increase in disease intensity occurred in parallel with the greater density of P. capsici inocula in soil. The density of P. capsici inocula in the soil tended to decline when the disease intensity reached the highest level.

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

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.
