Abstract

The low content of colloid material such as clay and organic matter in sandy soil (volcanic ash Regosol) cause the soil less supportive in water and nutrient. Mount Merapi eruption in September 2010 is a natural process. The problem is the amount of ashfall which is different on each place. The legume is suggested to give a better effect on soil fertility due to enrichment of N content in the soil after the eruption.The experiment was conducted in a green house of Soil Departement, Agriculture Faculty of Gadjah Mada University from February to May 2011. The experiment was carried out using two blocks of two factorial arranged in completely random design. Each combination was replicated three times.The results showed that ashfall, chicken manure and cow manure increase slow drainage pore and N uptake. This treatment decrease total porosity, non usefull pores, water holding pores and quick drainage pores. Chicken manure and cow manure tend to generate rate of plant height at first to fifth week of growth. The rate of application of 30 tons/ha chicken manure and 10 tons/ha cow manure resulted in the highest growth compared to other treatments. The treatment of chicken manure tend to increase seed weight and 13.39 tons/ha cow manure tend to produce optimal seed weight. The optimum production of peanut is achieved by addition 10 tons/ha ashfall and 20 tons/ha cow manure. This mixture may be used as a recommendation to produce the optimal fertility condition for the volcanic ash Regosol.Key words: ashfall regosol, ashfall, chicken manure, cow manure, peanut.

Abstract

Response on Growth and Yield of Peanut (Arachis Hypogeae L.) by Potassium Fertilizing and Soil Tillage System.The purpose of the study was to determine the effect of the interaction between potassium fertilizer application and soil tillage systems on the growth and yield of peanuts and getting potassium fertilizer and tillage systems optimum for the growth and yield of peanut.The experiment was conducted approximately four (4) months since September 2012 until December 2012 starting from land preparation to harvest. The research was located in the Ponoragan village of Loa Kulu Sub District of Kutai Kartanegara Regency in East Kalimantan Province.Randomized Completely Block Design (RCBD) was used as factorial experimental design with three times replication. The first factor was Potassium Fertilizer with four levels, i.e. k0 = 0 kg K2O ha-1 ; k1= 30 kg K2O ha-1 equal with 32 g KCl plot-1 ; k2 = 60 kg K2O ha-1 equal with 63 g KCl plot-1 and k3 = 90 kg K2O ha-1 equal with 95 g KCl plot-1. Whilst the second factor was soil tillage system with three levels, i.e. s0 = no tillage ; s1 = minimum tillage and s2 = maximum tillage (intensively tillage).The results showed that application of potassium fertilizer was significantly affected to height of plant, number of pods per plant, number of void pods per plant, weight of seed per plant, number of dry seed per plant and production of dry seed. The highest of dry seed production was reached at k3 = 90 kg K2O ha-1equal with 95 g KCl plot-1 with average 1.61t ha-1.The results also showed that soil tillage system was significantly affected to height of plant, number of pods per plant, number of void pods per plant, weight of seed per plant, number of dry seed per plant and production of dry seed. The highest of dry seed production was reached at s2 = maximum tillage (intensively tillage) with average 1.78t ha-1.Interaction between application of potassium fertilizer and soil tillage system was not affected to all parameters observed.Keyword : Peanut, Potassium Fertilizing, Soil Tillage System

Abstract

A study of the soil moisture dynamics and conservation resulted from the mulch adding and soil amendment was carried out in the Laboratory of Soil Science of Agriculture Faculty of Gadjah Mada University. The experiment was conducted using a Factorial Completely Randomized Design consisting of mulch adding (Mo = without the mulch and M1 = with the mulch) and fourrates of soil amendment (Po = 0, P1 = 4, P2 = 8 and P3 = 12 Mg.ha-1). The experiment used Mediteran top soil ( Vertic Eutropepts ). Tensiometers were installed at the 15, 30 and 45 cm soil depths of all plots. Every treatment was repeated three times. The soil properties which were observed included particle size distributions, bulk density, particle density, soil moisture characteristic. Soil temperature, saturated and unsaturated hydraulic conductivity, organic matter, fulvic acid, C/N and HA/FA ratios. Tensoimeter readings were taken daily, diurnal variation in soil temperature at a depth of 15 cm and air temperature were monitored with thermometers. The result of this experiment, generally speaking, showed that the mulch adding decreases the upward flow of the soil moisture and reduces the evaporation rate and then decreases the loss of the soil moisture. The soil amendment from the green manure does not have a role to improve soil physical properties. However, it increases the ability to hold the soil moisture, so the loss of soil moisture resulted from percolation is decreased. In fact, the role of soil amendment to increase the soil moisture content is less than the mulch, and then there is no interaction between the two factors which are tested.Key Words : mulch, soil amendment, soil moisture dynamics, soil moisture conservation.
