Abstract

Title : The Effect of Litter Quality of Gliricidia maculata and Salacca edulis to Inhibition of Nitrification and Efficiency N Benefit in Alfisols. This research was carried out from august 2008 to February 2009. The purpose of this research were to know the effect of litter quality of Gliricidia maculata and Salacca edulis to inhibition of nitrification and efficiency N benefit in Alfisols.This research was field research with Randomized Completely Block Design (RCBD) one factor with 11 treatments that repeat 3 times become 33 trial units. This treatment use control, without litter quality + N manure, Gliricidia maculata with dose 5, 10, and 15 ton/ha + N manure, Salacca edulis with dose 5, 10, and 15 ton/ha + N manure, and combination with dose 5, 10, and 15 ton/ha + N manure. To know the effect of treatment with variable used F test 1 % and 5 %. To know the difference between treatments used DMRT 5 %. Database analysis was used Minitab, Excel, and SPSS software. The result of this research showed that the litter quality of Salacca edulis (low quality) and Gliricidia maculata ­ (high quality) not significant inhibit and decrease nitrification. This result can be known from the effect test of potential nitrification, concentration of NH4+ and NO3- that not significant. The average of efficiency N benefit each litter quality are 0.59 % at litter quality of Gliricidia maculata ­ (high quality), 0,669 % at litter quality Salacca edulis (low quality), and 0,667 % at litter quality of combination between Gliricidia maculata and  Salacca edulis.

Abstract

Title : Inventorying and Erosion Hazard Clasification by Geographic Information System in Sempor- Gombong Reservoir Upstream Area. Sempor reservoir is located about 5 km northside of Gombong – Kebumen Regency, has decreased of water reservoir volume about 45% in 2002. The aim of this research has established erosion hazard classification in Sempor reservoir upstream area. This research conducted on April until October 2007. The method used explorative descriptive that was began with interpretating of Landsat 7 ETM+ image satellite and continue with field survey. The erosion prediction calculating used Universal Soil Loss Erosion Equation (USLE) based on land unit.The result shows erosion hazard level has dominated by very heavy level with 2,413.84 ha (55.70 %). The erosion hazard index has been dominated by very high class (2,129.45 ha or 49.14 %). High erosion is caused slope factor, especially on land whose very heavy Erosion Hazard Level and high until very high Erosion hazard index. This research give 8 recommendations about soil conservation technical based on soil deep, erosion prediction amount and erosion hazard level.

Title : The Effect of Plant Spacing and ZA Fertilizer to Availability and Uptake of N, S with Groundnut  (Arachis Hypogaea L.) Indicator on Alfisols. The aim of this research is to know the effect of ZA fertilizer and plant spacing to the availability and uptake of Nitrogen and Sulfur. This research have been done at Jumantono field, Sukosari, Jumantono, Karanganyar, started from December 2006 until January 2007. This research used factorial experiment that arranged in Randomized Complete Block Design (RCBD) with two experimental factors. The first factor was 4 levels of ZA fertilizer dosage i.e : 0 kg/ha (Z0), 50 kg/ha (Z1), 100 kg/ha (Z2) and 150 kg/ha (Z3). And second factor was 3 levels of plant spacing i.e : 20 x 20 cm (J1), 30 x15 cm (J3) and 25 x 20 cm (J3). Observation variables include soil variable ( N of soil, available S and pH H2O) and plant variable (N uptake, S uptake, and weight of dry straw). Data analysis used F test, Kruskal-Wallis test, Duncan’s Multiple Range (DMR) test at 5% in level, Mood Median test and Correlation test.Result of this research shows that ZA fertilizer and plant spacing can increase the available sulfur on soil and uptake of N. The highest available S neach 100 kg ZA/ha and 30 x 15 cm plant spacing (0,0277me/100 g),.and the highest average of N uptake is on without ZA and 30 x 15 cm plant spacing (0,623g). ZA fertilizer added and plant spacing has no significantly effect to  available N, S uptake, weight of dry straw and pH H2O.

Abstract

Title : The Effect of Equally Inorganic Fertilizers and Sipramin on Availability  of P and K and the yield of paddy (Oryza sativa L.) at Vertisols (Plant Season II). This field research conducted from march-august 2005, in Tambakkromo Village, Kecamatan Geneng, Kabupaten Ngawi.The aim of this research was to know the effect of sipramin on availability  of  P and K and the yield of paddy at second plant season. This field experiment used Randomized Complete Block Design with  one factor, consist of 20 treatment, that is: P1 (Sipramin Amina 2000 l.ha-1), P2 (Sipramin Amina 4000 l.ha-1), P3 (Sipramin Amina 2000 l.ha-1 and NPK fertilizer), P4 (Sipramin Amina 2000 l.ha-1 and PK fertilizer), P5 (Sipramin Amina 4000 l.ha-1 and PK fertilizer), P6 (Sipramin Bagitani 2000 l.ha-1), P7 (Sipramin Bagitani 4000 l.ha-1), P8 (Sipramin Bagitani 2000 l.ha-1 and NPK fertilizer), P9 (Sipramin Bagitani 2000 l.ha-1 and PK fertilizer), P10 (Sipramin Bagitani 4000 l.ha-1 and PK fertilizer), P11 (Sipramin Orgami 2000   l.ha-1), P12 (Sipramin Orgami 4000 l.ha-1), P13 (Sipramin Orgami 2000 l.ha-1 and NPK fertilizer), P14 (Sipramin Orgami 2000 l.ha-1 and PK fertilizer), P15 (Sipramin Orgami 4000 l.ha-1 and PK fertilizer), P16 (Sipramin Saritana 2000 l.ha-1), P17 (Sipramin Saritana 4000 l.ha-1), P18 (Sipramin Saritana 2000 l.ha-1 and NPK fertilizer), P19 (Sipramin Saritana 2000 l.ha-1 and PK fertilizer), P20 (Sipramin Saritana 4000 l.ha-1 and PK fertilizer). F-test or Kruskal-Wallis test 1% and 5% was used to know the effect of treatment on experimental result. Duncan multiple range test 5% is used for comparing inter-treatment. For finding out the relation between primary dependent variable and secondary dependent one it is used correlation test. The result of this research indicates that sipramin fertilizer within dose 2000-4000 l.ha-1, with or without N, P, and K fertilizer added, increasing the P and K availability on the soil at the same range with inorganic fertilizer’s used (control) and the apllication of sipramin has a significant effect on yield of paddy, that is, the rice weight per plot. The highest available-P on Bagitani apllication, dose 4000 l/ha with P and K fertilizer added (P10), that is, 0,045%; 0,024% higher than control. The highest available-K on Saritana apllication, dose 2000 l/ha with N, P and K fertilizer added (P10), that is, 0,030%; 0,018% higher than control. Sipramin Saritana 2000 l.ha-1  with N, P, and K fertilizer added (P18) give the highest on yield of paddy, that is, the average rice weight per plot is 4,88 kg, of 0,46 kg higher than control. Equals with 511 kg.ha-1.
