Publisher : Brawijaya University

Efforts to increase soybean productivity must be synergy with the improvement of soil fertility through fertilizer, especially organic fertilizer. Population density of a crop determines to a greater extent its performance in terms of soybean yield. Based on the two cultivation techniques mention above, that is expected to increase soybean productivity. The objective of this research was to obtain organic fertilizer and plant spacing that can support the development of early-medium maturity soybean (Lokal Jateng soybean lines/Sinabung-1036) to achieve 3 ton dry seed per hectare. The research was conducted at Alfisol soil Muneng Station Research, Probolinggo and at Entisol soil Genteng Station Research, Banyuwangi on dry season (DS) 2012. The experiment used split plot design with three replications. As the main plot was plant spacing, namely: 1) 40 cm x 10 cm, 2 plants/hole, 2) 40 cm x 15 cm, 2 plants/hole, 3) 40 cm x 20 cm, 1 plant/hole, and 4) 40 cm x 20 cm, 2 plants/hole. As the sub plot were four doses and types of organic fertilizer, namely: 1) without organic fertilizer, 2) 2.5 t manure/ha, 3) 5 t manure/ha, and 4) 2 t Santap NM-2/ha. The result showed that the potential yield of 3 t/ha for large, early-medium maturity soybean could not be achieved at Alfisol soil Probolinggo and at Entisol soil Banyuwangi by planting soybean of Lokal Jateng soybean lines/Sinabung-1036 with plant spacing 40 cm x 10-20 cm, 1-2 plants/hole and application of 2.5-5 t manure/ha or 2 t Santap NM-2/ha

Publisher : Brawijaya University

The information on the length of dry spells could be used for deciding a particular crop or variety, supplementary irrigation water demand and for others agricultural activities. The study was conducted in three districts: Babile, Haramaya and Kersa, eastern Hararghe, Ethiopia. The aim of the study was to analyze dry spell lengths and its implications on crop production in eastern Hararghe, so as to minimize unexpected damage due to long dry spells and to have effective and efficient planning for farming communities. Thirty years of rainfall data for each district were collected form National Meteorological Agency of Ethiopia. Data quality control has been done prior to analysis. Markov-Chain model were employed to analyze the collected data. The result of the study revealed that dry spells were highly hitting Babile district comparing to the other two districts. The probability of dry spell lengths of 5 and 7 days in Babile district was found to be about 99 and 80%, respectively. Whereas, in Haramaya district, the probability of dry spell length of 5 days was found to be 80% during 181(Days of the Year) DOY, then it falls to below 50 % by 221DOY. Moreover, the probability of the occurrences of dry spells of 10, 15, and 20 days were below 5% in Haramaya district during the main rainy season. The study also investigated that in Kersa district, the probability of occurrences of the dry spell lengths of 5, 7, 10, 15, and 20 days were estimated to fall below 30%, showing that the area was better in crop production as compared to the rest districts. The annual rainfalls in all the districts were decreasing as per the trend line and variable in all the districts: Babile, Haramaya and Kersa districts, having the CV values of, 41, 34 and 31%, respectively. Information regarding dry spell length analysis has to be well understood at grass root levels to ensure food security via lifesaving irrigation schemes or any other options.

Publisher : Brawijaya University

Soil moisture stress in coffee plant impacts on the productivity of coffee fruit at PT. Perkebunan Nusantara XII, it is because the low ability of the soil to store water. The ability of the soil to store water can be increased by increasing the organic matter content of soil, especially humic substances. Soil organic matter plays an important role in the improvement of soil physical properties, especially the availability of soil moisture for plants. The purpose of this study was to analyze several humification parameters at four age of plantations plots of coffee and its relation to the water distribution potensial on Inceptisol PT. Perkebunan Nusantara XII Malang district. The research was conducted at PT. Perkebunan Nusantara XII were taken soil samples from 8, 28, 40, and 80 years old robusta coffee plots at 0-30 cm and 30-60 cm soil depth. The results showed that the increasing the age of the coffee plantations significantly increased the input of organic matter in the soil, with indicators of increased litter on soil surface, increased levels of soil C-organic and N-total, humic acid and soil pH. Increasing age of coffee plantations until 80 years did not affect to the value of humification parameters (C/N ratio, HA/FA ratio, E4/E6 ratio, and the humification rate (HR)). The age of coffee plantations affected the total acidity, carboxylic groups and phenolic OH, where the values tended to decrease with the older of coffee plantations in the 0-30 cm of soil layers and increased in 30-60 cm. Increasing age of coffee plantations improved the total pores and available water content in the 0-30 cm of soil layer.

Agricultural lands affected by salt facing complex problems associated with soil salinity and the toxicity effects of Na cation. Soil amelioration and mulching is an alternative to alleviate negative effect of salinity. Objective of research was to identify effective ameliorant, and effect of mulching in improving growth and yield of groundnut on saline soil. The research had been conducted on saline soil (soil EC 12 dS/m) in Lamongan during dry season of 2016, using Hypoma 2 cultivar. Treatments that consisted of two factors were arranged in a split plot design with three replicates. The main plot was mulching (without mulching and mulching with 3.5 t/ha of rice straw), and the sub plot was soil ameliorations (control, 120 kg/ha K2O, 750 kg/ha S, 5 t/ha gypsum, 5 t/ha manure, and 1.5 t/ha of gypsum + 5 t/ha manure). Results showed that mulching, and amelioration with 120 kg/ha K2O, 750 kg/ha S, 5 t/ha gypsum decreased soil EC, but could not improve groundnut growth and could not retard chlorophyll degradation because the soil was EC still high (12.5 dS/m). The higher yield (1.49 t/ha dry pods) can be obtained by amelioration with 750 kg sulphur/ha combined with mulching

Steady soil aggregationis important for agricultural land which is formed by the micro-aggregate to become a macro-aggregate. This formation is mediated by organic material and various kinds of macro-organisms such as fungi, worms, ants and insects. An organic agencyinvolved in soil aggregation stabilityis exopolysaccharide (EPS) derived from bacterial, fungal mycelium, and products synthesized by plants. However, the use of EPS producing microorganisms as a biofertilizer has not been reported. This study was aimedto explore indigenous EPS-producing bacteria to solidify soil aggregationpotential for biofertilizer. Bacterial strains were isolated from soilsofthree regions at Malang East-Java; two areas of green bean plantation in Kendal Payak and Jambe Gede, as well as forest land. Soil samplewas derived from forest had hasa total bacteria population of 9.3 x 1011 CFU/mL.While soil samples from area Kendal Payak and Jambe Gede had total bacteria population of 1.5 x 109 CFU/mL and 2.4 x 109 CFU/mL, respectively. We selected three bacteria that could potentially produce abundant slime, namely as SPE-2, SPE-10 and SPE-20. The three selected bacteria are potential for biofertilizer because oftheir abundant slime, no antagonism and no symtoms as pathogen.

Cultivation of the golden teak (Tectona grandis L.) requires the planting hole size and appropriate use of manure. The size of planting hole provides plant growth, so that the plant can grow with optimum and appropriate use of manure to provide nutrients for the plants. . The aims of the study was to obtain an interaction between planting hole size and manure on vegetative growth phase of golden teak. Treatments tested in this study were with 4 treatment of planting hole size as the first factor and 3 levels of manure as the second factor. The twelve treatments were arranged in a factorial randomized block desiagn with three replicates. Variable measured plant height, number of leaves, and the flush changes to mature. The results showed that there were no interactions between the planting hole size and goat manure on early vegetative growth of golden teak plants. The planting hole size treatment showed significant effects on some variables height of plant, number of leaves and flush change to mature leaves. Manure treatment showed no significant effect for all variables. The observation variables that showed no significant differences height of plant, number of leaves and flush change to mature leaves.

Publisher : Brawijaya University

Glyphosate is the most widely used herbicide in Indonesia. Glyphosate persistence between 55 days to 3 years. Widespread and uncontrolled use can cause weeds to become resistant and residue contaminates the soil and water environment. Due to the residual impact of glyphosate, it is necessary to identify a method that can increase the degradation of glyphosate. Several studies have shown that glyphosate can be degraded by microorganisms (fungi, rhizosphere and endophytic bacteria), some of which are members of plant growth-promoting bacteria. This study used the bacteria Enterobacter cloacae, Enterobacter sp and Pseudomonas fluorescens. These three types of bacteria have growth-promoting properties and potentially increase glyphosate degradation. Results of chromatogram on the residual test of glyphosate in liquid medium and soil containing glyphosate showed that glyphosate residue decreased with the addition of bacterial treatment when compared to control. The percentage of degradation in liquid medium are 96.06% by Enterobacter cloacae, 57% by Enterobacter spand 93.45% by Pseudomonas fluorescens.The percentage of degradation in soil medium are 4.32% by Enterobacter cloacae, 23.49% by Enterobacter spand 12.19% by Pseudomonas fluorescens.A positive result indicates that bacterial growth boosters from the plant (endophyte) as well as the area of rooting (rhizosphere) have additional potential as biofertilizer, bio stimulant, bio protectant but also as bio degradator pollutants such as the herbicide glyphosate

Emerging development on the coastal region can result in coastal erosion and mangrove ecosystems damage. This disastercould eliminate settlements, agricultural land and public infrastructure. However, for mitigation of those events happened, the government has been constructing the Breakwaters andmangrove reforestation. We used survey method using quota sampling technique in 90 households. The study used a region-based approach. Measurement of socio-economic characteristics, knowledge, perception, and public participation were Chi square test and F test One-Way ANOVA. The results showed that most of samples were middle-lower socio-economy conditions (88.7%). The lower socio-economic caused of 1) the loss of residential and agricultural land due to beach erosion; 2) types of agricultural commodities; 3) work as farmers have the certainty get higher income than as fishermen; and 4) the ability of adaptation in the new location. The high public perception was not accompanied by high levels of public participation to rehabilitate coastal ecosystems

Mining using an open pit system may lead to a deterioration in the quality of the environment in term of the extent of the cleared land, heavy metals contamination on the overburden rock, the formation of acid mine drainage (AMD) with a pH <5, high level of total suspended solid (TSS), and the content of the metal on it. Several research results on post-mining land indicated a change in the environmental quality of the mine. Handling of the AMD problem can be conducted by several methods, including the active method by spreading calcium oxide (CaO) in AMD with the aim of increasing pH to neutral. The purpose of this study was to study the alternative techniques to manage the AMD using biostimulant. The present study was conducted firstly in the vinil house by using 10 L of AMD water sample with 2 kinds of treatment, i.e. CaO with levels of 0.2 and 0.25. Biostimulant with four kinds of treatment (I, II, III and IV) which resulted from the combination of different types of biostimulants (A, B and C) with different in composition. Secondly, research on the 1000 L of AMD for scaling up applications in the field. CaO and Biostimulant doses were obtained from the first stage of the study. Analysis pH, TSS, Fe, and Mn of the AMD were done on the control, CaO, and biostimulant treatments. CaO treatment resulted in an increase in pH to 6.9, TSS decreased significantly decline so to 60 mg/L. Fe content in AMD decreased to 0.22 mg/L, and Mn levels decreased to 0.12 mg/L on day 10. Biostimulant treatment resulted in increase of pH to pH 6.7. The TSS value decreased to 40 mg/L. Fe and Mn levels decreased to 0.03 mg/L and Mn 2.98 mg/L, respectively.
