Abstract

The appropriate method of P fertilizer application is very important for the efficiency of P uptake and yield improvement. This research aimed to assess the growth response, seed product, and P uptake efficiency of soybean to the application of fast dissolved phosphorus fertilizer. Two consecutive potted experiments under greenhouse condition were conducted using Alfisols from Jumantono Karanganyar as planting media. The soybeans were planted and treated with six doses of P fertilizer. The treatments were designed in a completely randomized experiment with 5 replications. In the first experiment, the plants were harvested at the maximum vegetative growth for measurement of plant growth components and P uptake. In the second experiment, the plants were harvested at optimum grain maturity for seed yield and P efficiency measurements. The results showed that the application of fast dissolved-P fertilizer improved plant growth, seed yield and P uptake efficiency. Fast dissolved-P fertilizer was optimum at a dose of 100 kg/ha which was applied in a split application method at 0, 15, and 30 days after planting. However further field research is necessary to confirm the results.

Abstract

This study aimed to assess the dose of zeolite plus organic compost and inorganic fertilizer on yield of chili pepper (Capsicum frutescens L). This study was conducted fromApril – July, 2012 in the Laboratory of Soil Science and in the glass house of Faculty of Agriculture UTP Surakarta, and was done under factorial design which was arranged in randomized completely design (CRD) consisting of two factors (doses of zeolite and doses of inorganic fertilizers) and three replications. The study concluded that the use of zeolit+organic compost increased yield of chili pepper significantly.  Application of zeolit+organic compost as much as 500 kgs ha-1 and 1000 kgs ha-1 increased significantly the weigth of fruit at every level of inorganic fertilizer.  By applying one half of dose of inorganic fertilizer, the treatment of 500 kg ha-1 of zeolit+compost yielded chili fruit as high as 141.67 grams per plant; and the treatment of 1000 kg ha-1 of zeolit+compost yielded chili fruit as high as 140 grams per plant. Those yield was not significant to the control treatment, which was as high as 141 grams per plant. Therefore it could be concluded that the application of zeolit+compost under doses of 500 kg ha-1 and 1000 kg ha-1 could reduce the use of inorganic fertilizer up until 50 percent.

Abstract

Ultisols are characterized as acid soils with high exchangeable Al as the primary constraint for plant growth. This study aimed to investigate the effect of the proportion of lime and organic matter in decreasing exchangeable Al on Ultisol Bogor and continued to observe the impact on the growth and nodulation of peanuts. The pot experiment used a completely randomized design with a single treatment of the addition of ameliorant consisting of 12 levels of the treatment of lime (calcite and dolomite), organic matter (dry cow dung and rice straw compost), and their combinations with three replications. The first step was applying the ameliorant and incubating for eight weeks, then continuing the cultivation of peanuts. Results showed that during incubation, the decrease in exchangeable Al levels varied between treatments, along with an increase in soil pH and available P. The treatments of calcite 100% (T1) and dolomite 100% (T2) showed the highest increase in soil pH and available P and the highest decrease in exchangeable Al. The result of plant growth showed that the highest plant dry weight, N-uptake, and P-uptake were obtained by the treatment of dolomite 25% + rice straw compost 25% + dry cow dung 25% + NPK 25% (T10), whereas the highest number and total weight of nodules were obtained by the rice straw compost 50% + dry cow dung 50% (T7) and dolomite 25% + rice straw compost 75% (T8).

Abstract

Plant canopies can protect the soil surface from raindrops and rooting activities that cause changes in biophysical properties. A low infiltration rate will reduce the soil’s capacity to store water to be low, resulting in a high soil erodibility value. This research aims to obtain infiltration values on different land cover, analyze the effect of land cover on soil infiltration rate, and analyze the effect of soil infiltration rate on soil erodibility. The research includes exploratory, descriptive research with a purposive sampling method. The study results show an increased soil infiltration rate can reduce soil erodibility. The infiltration rate of 74-year-old mahogany land cover ranged from 1.94–3.03 cm/hour, 50-year-old mahogany 1.61 cm/hour, old pine 1.53–1.89 cm/hour, old tapped pine 1.54–3.43 cm/hour, young pine 0.48–1.60 cm/hour, young pine 0.37–0.61 cm/hour, and 5-year-old sonokelling 0.56–0.73 cm/hour. The highest infiltration value is in 74-year-old mahogany and the lowest in young pine. The highest soil erodibility value is in young tapped pine and the lowest in 50-year-old mahogany. Erodibility is the sensitivity of soil to erosion. It is easier to erode if its erodibility value is higher; conversely, erosion is less likely to occur if its erodibility value is lower. An increase in soil infiltration rate can reduce soil erodibility. Keywords: Horton method, land cover, Mount Bromo, soil erodibility, soil infiltration rate

Abstract

Landslides are natural disasters that most often occur in hilly areas, one of which is in the Manyaran District, and are caused by land use, slope, and rainfall. This study aimed to assess the level of landslides on several slopes and determine the soil characteristics that most determine the level of landslide vulnerability to formulate an appropriate strategy for hilly land management. The sampling points used land map units (LMU) overlaid on thematic maps (land use, soil type, and slope), and were divided into 22 LMUs with three repeats for each LMU. The landslide level was calculated using a cumulative weight score. It was grouped based on the interval formula and modifications to the addition of permeability and soil texture parameters, while the determinants were analyzed using ANOVA and Pearson’s correlation. The results showed that the area was not very low (133.2 ha), low (1,015.33 ha), moderate (1,205.46 ha), high (3,248.48 ha), or very high(734.1 ha). The highest landslide hazard was on steep land (25–45%), and the determining factors were permeability and texture. The steeper the slope and the higher the permeability and soil texture values, the higher the landslide. The recommended landslide mitigation strategies are terracing and minimum tillage on agricultural land. Research on the level of landslides and information on determinant soil characteristics helps stakeholders formulate policies and manage agricultural land on hilly agricultural land.

Abstract

The low efficiency of Phosphate fertilization on wetland rice may be overcame by using quickly dissolve P fertilizer. However, for soils containing high dissolve Fe, such as Alfisol and Oxisol, will induce the formation of Fe-P bonding. Therefore, to use the quickly dissolve P fertilizer  in such soils should be done by split application. The research aimed to assess better P fertilization method for wetland rice which used quickly dissolve P fertilizer given in split application. The research concluded that the application of quickly dissolve P fertilizer to Alfisol and Oxisol which was applied in split application by twice (0 and 30 days after planting) and three times (0, 15 and 30 days after planting) increased the eficiency of P fertilization in wetland rice.  The split application of 75 kgs perhectare (one half of recommended dose) in Alfisol yielded dry seed as high as 6,374 kgs per hectare (at the twice application), 6,280 kgs per hectare (the three times application)c while the control treatment yielded as high as 6,027 kgs per hectare.  In Oxisol the yield of rice was 8,200 kgs per hectare fo the control treatment, 8,027 kgs per hectare for the twice application and 8,440 kgs per hectare for the three time applications.

Abstract

In an effort to solve the P availability issue in Inceptisols, fermentation is one method used to enhance the quality of liqiuid organic fertilizer (LOF) made from Moringa (Moringa oleifera). The type and concentration determine the effectiveness of LOF on nutrient uptake and plant yields. This study aims to evaluate the impact of LOF types, concentrations, and their interactions on P uptake and rice grain yield in Inceptisols. The research was conducted in a greenhouse using a completely random design (CRD) with two factors. The first factor is the type of LOF, consisting of two levels, i.e., fresh and fermented Moringa extract. The second factor is the LOF concentration, with four levels (i.e., 0, 20, 40, 60, and 80 ml/l) and three replications. Data analysis using ANOVA, DMRT, and correlation. The study revealed that the interaction between LOF types and concentrations affects P uptake. The highest P uptake shown by fermented Moringa with a concentration of 60 ml/l was 20.02 mg/plant and 40 ml/l was 18.73 mg/plants., or 1.5 times higher than the control. Grain yield was not affected by type, LOF concentration, or interaction. Fermented Moringa has good potential as LOF, while the effect on grain yield needs further research.
