Abstract

Sugarcane development in Indonesia has shifted to dry land to meet the needs of the national sugar. However, there are many limiting factors like sandy texture, loose structure, low water holding capacity and low nutrient availability that are required to be solved improve to support plant growth and production. Application of soil conditioner is one of the ways to improve the physical properties of a sandy soil. This study was aimed to examine the benefits of sugarcane trash biochar, boiler ash, sugarcane trash compost, and manure as an alternative soil conditioners to improve some of the physical properties of sandy soil and its relationship to the growth and production of sugarcane. Treatments tested in this study were P0= control (without soil conditioner), P1= sugarcane trash 10 t ha-1, P2 = sugarcane boiler ash 10 t ha-1, P3 = manure 10 t ha-1, P4 = sugarcane trash compost 10 t ha-1, and P5 = sugarcane trash 5 t ha-1 + manure 5 t ha-1. The results showed that all treatments increased aggregate stability with very significant compared to the control at 5-11 months after planting. The best results were shown by the treatment of 10 t ha-1 of sugarcane trash biochar that could consistently improve sandy soil aggregate stability at 5-11 months after planting. Application of biochar and others soil conditioner also significantly affected  soil bulk density, pF 4.2, available water content, penetration resistance, Lrv, plant height, stem diameter, although they did not consistently occur in the entire observation period. Overall effect of sugarcane trash biochar and others soil conditioners to physical properties of sandy soil had no effect on increasing the growth and production of sugarcane.

Abstract

The ability of sandy loam soils to hold water and nutrients is very low because of unstable soil aggregation. One of soil bacteria that can improve soil aggregates is Lactobacillus fermentum that is able to produce producing exopolysaccharide. The objective of this study was to explore the effect of application of Lactobacillus fermentum on improvement of chemical and physical properties of a sandy loam soil. Lactobacillus fermentum isolated from shrimp paste was used for soil aggregation tests. The treatments were P0 (450 mL distilled water), P1 (100 mL selected media + 350 mL distilled water with 1.67 x 104bacteria), P2 (200 mL selected  media + 250 mL distilled water with 2.13 x 105 bacteria,  dan P3 (400 mL selected  media + 50 mL distilled waiter with 3.54 x 106bacteria. The results showed that molasses give the best effect for bacterial growth compared with other media (coconut water, legen and sugar solution). Application of Lactobacillus fermentum significantly increased aggregate stability of the soil studied. In the initial analysis, soil aggregate stability was 0.48 mm (less stable. After incubation period up to 30 days the P1, P2 and P3 treatments increased aggregate stability by 1.27 mm (very stable), 1.43 mm (very stable), and 2.05 mm (very very stable), respectively. Lactobacillus fermentum also gave effect to the increase in organic matter, available P and K available. However, this bacterium did not give effect to an increase in available N and soil pH.

Abstract

The main problem in the Indonesian rubber plantations is white root rot disease (Rigidoporus microporus). White root rot disease causes the death in rubber so that the amount of crop production declines. The growth of white root rot in the soil is influenced by the nature of the soil itself that include  soil physical, chemical and biological properties. It is known that the white root rot disease likes porous soils. The purpose of this study was to determine the effect of soil physical properties on  the intensity of white root rot disease attacking the roots of white rubber plant. The study was done by calculating the intensity of disease and soil sampling for analysis in laboratororium. The results showed that the physical properties of soil that influenced the intensity of white root rot was organic matter 10.75%; clay fraction 30.53%; pH 30.8%; available moisture 40.69%; sand fraction 41.9% and porosity 73.37%. However, the porosity of the soil had a very strong influence and it was highly significant (p <0.01) with the regression equation y = 226.32 - 5,0311x. The high porosity of the soil was able to suppress the intensity of white root fungus attacks.

Abstract

Based on data from Malang District in 2015, Pakisaji has the potential to reach 17,000 tons of rice yield. However, it has some hindrance in water availability that affects rice planting planted using conventional methods. One of the rice cropping system that can be used to reduce water usage is SRI (System of Rice Intensification) method. The goal of this study was to know the content change of  soil N, P, K due to application of NPK 15-15-15 fertilizer combined with biofertilizer using SRI method and determine the level of crop production. The results of this study showed that the application of NPK 15-15-15 fertilizer combined with biofertilizer in SRI method produced the highest soil nutrient content such as total nitrogen (0.29%), P availability (26.31 ppm), and K availability (0.58 me 100 g-1 especially at the depth of 0-20 cm. The combination of NPK 15-15-15 fertilizer and biofertilizer applied in SRI method obtained the highest yield at a weight of 1000 seeds (30.31 g) and yield of dry grain harvest (8.4 t ha-1).

Abstract

During dry seasons, paddy soils are usually deficit or shortage of water that in turn affecting chemical properties of the soils. The aim of this study  was to look for the effects of coconut shell charcoal and rice husk ash on the improvement of soil properties and growth and yield of maize. The study was conducted in Nganjuk and basic soil analysis was carried out at the Faculty of Agriculture, Brawijaya University. The experimental method used two factors. The first factor was the dose of rice husk ash which consisted of four levels i.e. without husk ash (A0), rice husk ash 50 g polybag-1 (A1), rice husk ash 100 g polybag-1 (A2), and rice husk ash 150 g polybag-1 (A3). The second factor was the dose of coconut shell charcoal which consisted of four levels i.e. without coconut shell charcoal (B0), coconut shell charcoal 50 g polybag-1 (B1), coconut shell charcoal 100 g polybag-1 (B2), and coconut shell charcoal 150 g polybag-1 (B3). Based on the results of the analysis showed that the application did not show significant effect of the two parameters, namely chemical properties and plant growth. But at the treatment of 150 g  polybag-1 coconut shell and husk ash significantly increased the pH value to 5.7.

Abstract

Nitrogen is a macro nutrient needed to support growth and productivity of sugarcane. Nitrogen requirement for sugarcane can be met through organic, inorganic, and biological fertilizers. The objectives of this study was to analyze the effect of N fertilizer treatments with the use of nitrogen-fixing endophytic bacteria Gluconacetobacter diazotrophicus on levels of nutrient nitrogen and the growth of sugarcane. Treatments tested in this study were P0 = control (no added fertilizer and bacteria), P1 = (800 kg N ha-1 + 5 mL bacteria inoculation), P2 = (600 kg N ha-1 + 5 bacteria inoculation), P3 = (400 kg N ha-1 + 5 mL bacteria inoculation), dan P4 = (200 kg N ha-1 + 5 mL bacteria inoculation). The results showed that treatment of N fertilizer doses did not significantly different for  populations of endophytic bacteria Gluconacetobacter diazotrophicus and the vegetative growth of sugarcane. Doses of N fertilizer treatment with utilization of endophytic bacteria Gluconacetobacter diazotrophicus only significantly different on  N-total and N uptake of sugarcane. Treatment in P2 (600 kg N ha-1 + Gluconacetobacter diazotrophicus 5 mL) has a larger population of Gluconacetobacter diazotrophicus endophytic bacteria than other treatments, is 53.0 x 102 cfu mL-1, and has higher levels of N-total than other treatment is 0.16%. For vegetative growth of sugarcane in P1 (800 kg N ha-1 + Gluconacetobacter diazotrophicus 5 mL) had a good influence for the high, number of leaves, dry weight and N uptake of sugarcane. While the  number of tillers in P4 (200 kg N ha-1 + Gluconacetobacter diazotrophicus 5 mL) has a seedling growth more than other treatments

Abstract

This study was aimed to identify the distribution of productivity and quality of Temanggung tobacco, identify relationships between soil erodibility with soil compaction and productivity quality of Temanggung tobacco, and identify relationships between soil erodibility index with productivity and quality of Temanggung tobacco. The study was conducted by field survey method with the object of study was tobacco fields in Temanggung Regency, Central Java. Based on the data obtained, two maps i.e. map of productivity distribution and map of Temanggung tobacco quality. The results showed that the soil compaction affected the value of erodibility index. The higher of the soil compaction, the lower was the value of soil erodibility. It was because the compaction of the soil influenced one aspect of erodibility. The soil compaction affected the productivity but did not affect to the quality of Temanggung tobacco. The more compact the soil, the lower the productivity of the land, it was because root development was hampered by the dense soil, thus affecting the development of other plants (leaves). While erodibility did not affect productivity, it affected the quality of tobacco. The higher erodibility indicated the lower quality tobacco. This was because the high soil erodibility increased soil sensitivity to erosion.
