<p>ABSTRACT</p><p>Rainfed ricefield, planted at least for one cropping season in a year, depends heavily on rainfall for its water supply. This land generally is low in fertility as indicated by the limited availability of essential plant nutrients in particular nitrogen (N), phosphorus (P), and potassium (K) as well as organic matter. Its productivity is relatively low with a rather erratic precipitation distribution. In order to overcome fertility issue in rainfed land, it is necessary to conduct an integrated nutrient management; one of which is by implementing location specific nutrient management. This study aims to seek the appropriate nutrient management in rainfed paddy field of Semawung village in the sub-district of Andong of Boyolali regency to be provisioned as a technological tool of location specific nutrient management. Research on nutrient management of gogo rancah system-based paddy production was carried out from October 2014 to January 2015. The field experiment was arranged in a Randomized Block Design involving eight treatments and three replications for each treatment. Treatments were combinations of NPK fertilizer, Organofosfat, and straw-based organic fertilizer. Nutrient management using NPK fertilizer and its combination with Organofosfat or organic fertilizer had very significant effect on plant height and number of stem per hill, significantly affected number of panicle per hill, panicle length, and number of fully-filled grain but did not result in difference of fully filled grain percentage and weight of 1000 grains. There was no significant difference between the treatment of 100% of NPK fertilizer and the combination of 75% of NPK fertilizer with straw-based fertilizer regarding these variables: number of stem per hill, number of panicle per hill, panicle length, number of grain per hill, number and percentage of fully-filled grain, weight of 1000 grains, and weight of fresh grain and milled grain yield. Therefore, the latter treatment is feasible as an option of location-specific nutrient management Semawung village.</p>

Utilization of maize waste as the organic matter sources in agricultural land couldn’t be directly applied, caused by late decomposition prosess. An effort to accelerate of maize waste decomposting needed bioactivator. The research was conducted in green house and Bajeng Research Intallation from March to August 2015. The research was arranged in randomized block design using isolate bacteria and fungus just one or theier combining ie: three bacteria  (B7.1,E7.7and E7.11), three fungus (M7, O5, P7), and four bacteria-fungus combining(B7.1+O5, B7.1+M7, E7.7+P7, B7.1+E7.7+O5), EM4 and N,P,K fertilizer(200,45,60) ha-1as the check treatment. Just one isolate fertilized by 75 percent N,P,K while combine isolate fertilized by 50 percent N,P,K recommended. The results indicated that just one decomposer E7.7 produced high enouugh grain yield not siqnificantly different by N,P,K (200,45,60) and five other just one treatment (E7.11,B7.1,M7 and O5), however siqnificantly different with combining decomposer (B7.1+O5, E7.11+M7, E7.7+P7, B7.1+E7.7+O5 and EM4). This mean that using stalk plus leaf waste maize compost could be subtitution in organic fertilizer untill 25 percent. Meanwhile combining decomposer was good enough for composting stalk and leaf of maize waste ie. isolate B7.1+O5 and E7.7+P7 although not significntly different with the other combine isolate including EM4. Thise case related by applied 50 percent N,P,K inorganic recommended fertilizer did not sufficient to supporting maize nutrient.Key Words: Decomposer, Bacteria, Fungus, Composting,Maize waste

Andisols  are characterized  by  dominance  of  amorphous  minerals  which form strong and stable bonding with organic matter, therefore Andisols always contain high organic matter. For that reason, organic fertilizer is generally not applied  on  Andisols,  because  it  is  assumed  that  it  will  not  give   any  positive effect  on  growth  or  yield.  The  experiment  was  aimed  to  evaluate  response  of mature Kartika 1  Arabica coffee variety (seven years old) cultivated on  Andisols applied with organic matter derived from cow dung manure. The experiment was carried out at Andungsari  Experimental Station located in Bondowoso District, East  Java. Elevation of the site was 1,150 m asl., with rainfall type of C (Schmidt &  Fergusson).  The  experiment  was    arranged  according  to  completely randomized  block  design  with  four  replications  to  evaluate  effect  of  ninecombination  treatments  of  application  rates  at   application  depths  of  50,  100, and 150 cm. The  range of organic fertilizers rates were  0 - 13.5 kg/tree/year. The experiment revealed that cow dung manure applications on Arabica coffee cultivated  on  Andisols  significantly  increased  yield  at  the  average  of  33% compared  to  the  untreated  crop.  No  significant  effect  of  the  treatment  onvariables of leaf water deficit and soil moisture content during dry season and root  density.  At  range  of  application  depths  of  50  -  150  cm,  the  deeper  the organic matter applications, the higher the yield will be.Key words: Andisols, Arabica coffee, organic matter, cow dung manure

Fertile agricultural land encourages people to carry out agricultural cultivation activities. But in general, it has decreased soil fertility because its managed intensively without recycling of organic matter and has an impact on decreasing soil fertility chemically such as soil organic carbon and pH then leads to low productivity. Soybean is an agricultural product that necessary to develop because the demand for soybean consumption in East Java Province has always increased. However, Indonesia has not been able to fulfil this demand. One of the technology innovations that can be applied to improve soil fertility that has low organic matter and to increasing soybean production by providing input of quality organic fertilizer in the form of compost (Tithonia and Cow Dung). So this research is important to determine the effect of application cow dung compost and tithonia on soil chemical properties, the growth of soybean crops, and the correlations between soil chemical properties and soybean growth. This study used a randomized block design with 6 treatments and 3 replications. The result showed that the application of tithonia and cow dung compost shows a significant effect on soil chemical properties, plant height, and the number of leaves, but didn’t show a significant effect on the number of branches in every observation. Based on the correlation analysis, the results show a positive correlation between soil chemical properties and soybean growth.

ABSTRACT The objective of this study was to evaluate the chemical attributes of the soil cultivated with ‘Gigante’ cactus pear under different doses of organic fertilizer, planting spacings and sampling times. Four doses of organic fertilizer with bovine manure (0, 30, 60 and 90 Mg ha-1 year-1), three spacings (1.0 x 0.5, 2.0 x 0.25 and 3.0 x 1.0 x 0.25 m) and three sampling times (0, 390 and 600 days after planting) corresponding to the periods prior to planting, growth and harvest of the first cycle, were evaluated in a randomized block design in a 4 x 3 x 3 factorial scheme, with three repetitions. The pH in water, macronutrients (P, K, Ca, Mg), micronutrients (B, Cu, Fe, Mn, Zn), variables of the soil sorption complex (H + Al, SB, CEC, T, V) and soil organic matter (SOM) were determined. Organic fertilization increased the values of SOM, P, K, Ca, Mg, SB, CEC, T and V and reduced H + Al in soils cultivated with ‘Gigante’ cactus pear at different times. The doses of manure increased pH and Mn, regardless of sampling time and spacing. The spacings did not influence the chemical attributes of the soil.
