Abstract

Title : Intercropping and Livestock Integration System : Changes in Physical and Chemical Properties of Litosol. Study sites located in the village Geneng duwur, District Gemolong, Sragen regency, Central Java with litosol soil type. Study sites are located between 7 º 23'10 "latitude and 7 º 23'17" latitude and 110 º 50'28 "E to 110 º 50'24" E with altitude between 150 masl to 155 masl. The experiment was conducted in February 2010 to November 2010. The purpose of the study: (1) Knowing the integrated effect of intercropping with cattle on soil physical properties, (2) Knowing the effect of intercropping systems are integrated with livestock on soil chemical properties. The study design used in this study is complete randomized block design consisting of two factors: factor 1: integration of cattle consisting of 4 standard (I0 = no cattle integration (0 years); I1 = 1 year of integration of cattle ; I2 = integration of cattle 2 years; I3 = integration of cattle 3 years) and factor 2: cropping system consisting of a 3 stage (K = monoculture cropping systems with groundnut crop; J = monoculture cropping systems with corn; KJ = cropping system intercropped with maize crop peanuts). Research results indicate that: (1) intercropping system does not significantly affect the improvement of soil physical properties include: soil density, volume weight of soil, field capacity, porosity; integration of livestock significantly affect the improvement of soil physical properties include: density of the soil, volume weight of soil, field capacity and soil porosity, (2) intercropping system did not significantly affect the chemical properties of soil improvement which include: soil organic matter, total soil N and soil pH; integration of livestock significantly affect the chemical properties of soil improvement material covering soil organic matter, total soil N and soil pH.

Abstract

Title : Efficiency of S Up Take and Rice Yield with Quail Manure and Inorganic Fertilizer in Paddy Soil (Season II). The aim of this research was to know the effect of inorganic fertilizer quail manure to efficiency of Sulphur up take and to know treatment combination that give highest rice yield. This research had been done at Palur, Mojolaban, Sukoharjo, started from January until August 2008. This research used factorial experiment that arranged in Randomized Complete Block Design (RCBD) with two factors. The first factor was 3 levels of inorganic fertilizer dosage i.e.: without inorganic fertilizer, 50% recommendation dosage and 100% recommendation dosage (urea, ZA, SP‐36 and KCl were 300, 100, 150 and 100 kg. ha‐1). And second factor was 3 levels of quail manure dosage i.e.:0, 3 and 6 ton.ha‐1. Statistical analysis used F test, Duncan’s Multiple Range (DMR) test at 5% in level and Correlation test. The Result of this research showed that, interaction between inorganic and quail manure increased significantly efficiency of S uptake. Dosage quail manure increased significantly total weight of dry hust. The highest efficiency of S uptake was on 100% recommendation dosage inorganic fertilizer and quail manure dosage 3 ton.ha‐1 (44.12%). The highest total weight of dry hust on 50% recommendation dosage inorganic fertilizer and quail manure dosage 6 ton.ha‐1 Key words: quail manure, efficiency of S uptake and paddy soil
