Abstract

The objective of the research was to study the effect of the application method of phosphate fertilizer to the growth and yield of several rice varieties in Alfisol. This pot experiment was done at a glass house of Sumber Banjarsari Surakarta, at an elevation of about 100 meters above sea level from February till July 2015. This study was done under factorial design arranged in a completely randomized design involving two treatments, method of phosphate applications (six levels of treatments) and three rice varieties (IR54, Membramo and Pepe variety). The study concluded that the rice varieties used in this study (IR64, Membramo, Pepe) showed no different response to fertilizer application P. Fertilization P in the form of fast soluble P applied insplit application can save fertilizer to half the dose.

Abstract

The study aimed to assess the response of four varieties of soybean (Argomulyo, Grobogan, Local Wonogiri dan Local Karanganyar) grown in different soil water content (100%, 70% and 40% of the field capacity). This pot experiment was done in the green house in Sumber Banjarsari Surakarta (at about 98 metres above sea level), using Factorial Experimental Design. The research consluded that soil water content as low as 70% and 40% of field capacity restrain plant growth and seed yield of all soybean varieties. This was indicated by the reduction of plant height, dry weight of  leaf, dry weight of root, dry weight of root and shoot and seed yield.  Water stress decreased significantly rhe vegetative growth of Argomulyo dan Grobogan varieties, but decreased significantly seed yield of bth local Wonogiri and Karangayar varieties. The varieties of Argomulyo and Grobogan are more drought tolerant compared to the local varieties of  Wonogiri and Karanganyar.

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
