Abstract

The need for food in Indonesia is relatively large, but not followed by optimal land conditions. One of the efforts to improve the quality of land that can be applied is biochar. Biochar used comes from corn cobs with nitrate acid enrichment. The purpose of this research is to know the effect of biochar application of corn cobs enriched nitric acid to C-Organic content, Nitrogen, and vegetative growth of corn plants at different soil pH. The research was implemented in September 2016 - March 2017 at the Tribhuwana Tunggadewi Experimental Garden. This study used a factorial randomized block design with two factors and three replications. The first factor of soil pHs were soil from West Borneo (As), Wajak (Ne), and NTT (Ba). The second factor of biochar applications were without biochar (K), biochar (Bio), and biochar enriched nitrate acid (BioN). The average effect of pH with biochar was no interaction except on the N-total content. However, overall application of 5 t ha-1 of biochar and biochar enriched nitrate acid had better C-organic, N-total, and growth of maize than control treatment on each soil.

Abstract

Biochar is one of amandement soil that comes from imperfectly combustion (pyrolysis) form of natural charcoal. The addition of biochar as a soil reparing was able to increase the carbon in the soil that able to improve soil characteristic soil. The purpose of this study was to find out the influence of residual biochar enriched with amonium sulphate on soil chemical and physical properties, and plant growth on various soil acidity levels. Treatments tested for this study were biochar residues enriched by amonium sulfate, N fertilizer (BN), biochar residues (B), without biochar, N fertilizer (N), and control (K) and various degrees of soil pH, i.e. pH 6-7 (P1), pH 4-5 (P2), pH 5-6 (P3). Twelve treatments were arranged in a randomzed block design with three replicates. Variables observerd were properties of soils (pH, C-Organic, CEC, N-total, and aggregate stability), and maize growth parameters (plant height and the number of leaves). The results showed that aplication of biochar of residues maize cob enriched with amonium sulfphate and various pH soil had interactions towards soil CEC and soil N-total, and had an interactions towards plant growth at plant age of 8 weeks-10 weeks, and number of leaves at age 9 weeks-10 weeks.

Abstract

Soil texture is one of the determinants of soil fertility. One of the efforts in overcoming the problems of soil is by biochar. The purpose of this study was to determine the ammonium sulphate enriched biochar residues on several soil chemical properties, N uptake, and rice yield on soils with different texture. This study that was conducted at experimental farm of Tribhuwana Tunggadewi University used a randomized complete block design with two factors, i.e.biochar and soil texture. Biochar factor consisted of zero biochar (T), chicken manure biochar (BK), and ammonium sulphate enriched biochar (BA). Soil texture factor consisted of sandy silt texture (P), silt (D), and clay (L). Parameters observed were soil chemical properties (organic matter, pH, CEC, total N total), N uptake by rice, rice plant height, rice panicle, productive tillers, grain dry weight, dried grain. Results of the study showed that ammonium sulphate enriched biochar residue affected the pH and N total soil in different textures, ie on clay texture, silt then sandy silt with values 6,39 ; 6,37; 6,13 and 0,08 %; 0,10 %; 0,09 %. Soil texture affected N uptake on clay texture, silt then sandy silt with value 15,97 g plant-1 ; 12,88 g plant-1; 7,42 g plant-1. Significant effects on plant’s height, productive tillers, dry weight of grain and dried grain to biochar factor, the ammonium sulphate enriched biochar had highest value 106,17 cm; 6.22 polybags-1; 12,74 g; 9,40 g.

Abstract

This study was held based on climate change impact as a present and future environmental issues on sustainable agriculture especially it’s impact on crop water availability. This study aimed to determine the impact of climate change on the water availability of sugarcane that was simulated using climate change scenarios based on global climatic analysis. Climate change was simulated for future scenarios using combination of temperature increase (2o, 4o, and 6o C) and rainfall change (∆CH -10, ∆CH -5, ∆CH +5, ∆CH +10%) from actual condition. This study took place at Wajak, Sumbermanjing, and Gedangan sub-districts, choosen by sugarcane plantation area with different soil conditions, especially soil texture. The result showed water demand increased 5-15% with the increasing of temperature, thus could impacting crop water availability especially during dry months period which could not fulfill crop water needs. The highest potential reduction was in Gedangan site which reached 5,1% in the C9 scenario (temperature + 6o C and rainfall -10%). The high quality in holding water could not assure the low potential reduction because it also depends on climatic conditions.

Abstract

The development of agriculture in dry land, is expected to contribute in the field of Indonesian agriculture. Dry land agriculture has some problem i.e. the low moisture content and drought. The drought that occurred in Gunungkidul, one of them. The purpose of this research was to evaluate the availability of water on some of the land use in each soil depth by using two approaches, namely evaluation of the evapotranspirasi and the characteristics of land, with the intend to present information about the relationship of some land use with the availability of water in dry land farming in Gunungkidul. Models were used to calculate evaporanspirasi and crop water needs, calculate the physical properties of the soil, and comparing the two calculations. The results of the analysis indicated that the availability of water in dry land farming in Gunungkidul Yogyakarta was influenced by the characteristics of the land (physical properties of the soil) 21,5% and the remainder was by other factors. The highest available water was on sugar cane plantation, 42,81% in 0-20 cm depth. The available water on forest land and teak product was 35,68% in 40-60 cm depth.

Abstract

Mount Kelud that is one of the most active volcanoes in Indonesia, erupted on February 13, 2014. The eruption damaged agricultural crops in Trisulo Village Kediri. This study was conducted in greenhouse of the Faculty of Agriculture, Brawijaya University. Soil samples were taken from Trisulo Village, Posoklaten District, Kediri Regency. This study used a completely randomized design with five treatments and three replications. The treatments consisted of A1 (100% Urea), A2 (100% composted chicken manure), A3 (100% composted cow manure), A4 (50% urea + 50% composted chicken manure), and A5 (50% urea + 50% composted cow manure). Soil variables observed were soil pH, total N, C-organic, C/N ratio, and CEC. Plant parameters observed were plant height and number of leaves of maize. The results showed that application of chicken and cow manure composts with dosage of 100% (12,27 t ha-1 and 18,73 t ha-1) each significantly increased pH and CEC of soil affected by Mount Kelud Eruption compared to the use of 100% Urea , and could substitute the use of 50% Urea. As for the N-total of soil, only 100% (12,27 t ha-1) each application of chicken manure compost could substitute 50% urea. Application of chicken and cow manure composts with dosage of 100% (12,27 t ha-1 and 18,73 t ha-1) each significantly increased the number of leaves of maize plants, and could substitute the use of 100% (288 kg ha-1) urea, although the highest leaf number was obtained in combination dosage of 50% urea and 50% chicken manure compost.

Abstract

Farmers use pesticides intensively in the cultivation of rice. The use of organic and inorganic fertilizers give in large quantities. Pesticides, organic and inorganic fertilizers contain heavy metals arsenic, so the provision of large amounts will accumulate in the soil. In addition to nutrients, rice plant tissue will absorb heavy metals including arsen. Indonesian government has implemented a quality standard of arsen in cerealia by 0.5 mg kg-1. This study was aimed to obtain quality standard of arsenic in an Inceptisol at planting of rice. Research conducted at the scale of pot to contaminate soil planted rice with rows 0 mg kg-1, 15 mg kg-1, 30 mg kg-1, 60 mg kg-1. Data observed that plant growth, yield and content of arsenic in the soil and plant tissue. Agronomic parameters and yield components performed statistical analysis of variance followed by Tukcey test. Growth and crop yield based on statistical analysis are significantly different. The quality standard of heavy metals on soil done by regression analysis between the content of arsen in the soil and rice seed. By incorporating quality standards of arsenic on the rice on the regression equation, obtained the quality standard of arsen in the soil. The analysis results obtained that the quality standards arsenic in an Inceptisol of Grobogan in the soil planting of rice of 17.5 mg kg-1.
