Abstract

The research aimed to study whether soil pH affects exogenous application of amino acid tryptophan and IAA in increasing root nodules and soybean yield. The experiment was conducted in greenhouse using 20 cm diameter plastic pot filled with fine soil, arranged in completely randomized design (CRD) with four treatments. Each treatment combination was repeated three times. Three seeds of local soybean variety were planted into each pot then to remain one plant a week after planting. Variables observed were root nodules number, shoot dry weight and seed yield. Plant nutrients were supplied in the form of solution to meet crop needs. The data obtained were analyzed statistically by F test at 5% of level confidence, followed by Duncans multiple range test when there was a significant effect. The results showed that both exogenous amino acid tryptophan and IAA increased number of root nodules, shoot and root dry weight and soybean yield. Higher root nodules number was taken from the treatment combination of 0.001 ppm IAA applied at V3 in Alfisol and Vertisols, and 1.0 ppm on Entisols. However, the highest soybean yields were taken from the treatment combination of 1.0 ppm tryptophan applied at V0 in Alfisols (6.51 g plant-1).Keywords: alfisol, entisol, extra cellular, phyto-hormones, vertisol

Abstract

Research aimed to study the influence of phosphate rock-sulfur (PRS) content and inoculum ratios of biosulfo on P and S uptake and red onion yield on acid (Alfisol) and alkaline (Vertisol) soils.  Two factors evaluated were PRS content (0%, 60%, 80%) and inoculums of A.niger/P.nalgiovensis ratio of biosulfo (0:0, 1:1 and 3:1). As much of 12 kg of soil (Ø 2 mm) mixed thoroughly with biosulfo, basic fertilizer and manure, put into polybag then watering at field capacity moisture content. One bulb of red onion was planted to each polybag and incubated in the green house. The experiments arranged in completely randomized design with three replications. Variables observed included P and S uptake, and onion yield. Data analyzed with F test at 5% level of significant followed with DMRT if any significant influences. The result shows that the increases of PRS content as well as A. niger ratio of biosulfo tend to increase P and S uptake, especially on acid Alfisol.   Highest P and S uptake and onion yield were achieved with treatment combinations of P80I11, P80I31, and P60 I11 for Alfisol,   and  P80 I11,  P60 I11 and P60 I11  for Vertisol respectively.   Keywords:  phosphate, rock content, inoculums ratio,P and S uptake, onion yield

Abstract

Produksi padi di Indonesia masih belum mampu menutupi kebutuhan nasional. Rendahnya produktivitas ini salah satunya disebabkan oleh penurunan tingkat kesuburan tanah. Salah satu cara untuk meningkatkan kandungan fosfat didalam tanah adalah dengan memberikan pupuk fosfat alam dan juga inokulum azolla. Penelitian ini dilakukan untuk mengetahui dosis yang tepat dari inokulum azolla dan fosfat alam untuk meningkatkan ketersediaan fosfat dan meningkatkan hasil tanaman padi pada tanah alfisol. Penelitian ini menggunakan metode RAL faktorial dengan dua faktor pembanding perlakuan pupuk kandang dan pupuk N,P,K. Analisis data hasil pengamatan menggunakan analisis ragam pada taraf 5% dan apabila terdapat pengaruh beda nyata dilanjutkan dengan uji DMRT taraf 5% untuk membandingkan antar perlakuan. Hasil penelitian menunjukan bahwa perlakuan pemberian inokulum azolla dan fosfat alam dapat meningkatkan ketersediaan fosfat pada tanah alfisol dan mampu meningkatkan hasil padi. Pada parameter P tersedia hasil tertinggi menunjukan pada perlakuan azolla 2,5 ton/ha tanpa fosfat alam dan azolla 5 ton/ha fosfat alam 350 kg/ha yaitu 10,81 ppm. Selain itu pemberian inokulum azolla dan fosfat alam memberikan peningkatan terhadap kadar KTK, bahan organik, N total dalam tanah dan pH tanah.

Abstract

Catfish farming is strongly influenced by the high price of feed, while azolla is a water fern that has a high nutritional value, can develop quickly and preferably by catfish as feed. The research aims to obtain the most appropriate combination treatment of Azolla inoculum dose and catfish seed size in dual system Azolla - catfish, which is able to provide the highest catfish yield. The experiments were performed in catfish ponds in completely randomized design (CRD) two factors, i,e azolla inoculum doses (250, 500 and 750 gm-1) and head circumference size of catfish seed (3, 4 and 5 cm). Dose of catfish seed is 2,000 head / m2. Variables observed were azolla fresh weight and catfish fresh weight at harvest. Azolla inoculum and catfish seed deployed together in catfish ponds and feeding with concentrate feed for one month. Azolla and catfish harvesting is done on the same day using a sieve. Once drained, Azolla and catfish were weighed separately to determine the severity. Data were analyzed by F test at the level of 95%, followed by Duncan's multiple range test (DMRT) if any significance influence. The results showed that the higher the  azolla inoculum number,  the higher azolla yield. The larger the size of catfish seed the higher catfish consumption to Azolla. Catfish seed size more than 4 cm will cause an imbalance between the speed of consumption of Azolla by the catfish and the azolla growth rate, so that Azolla be devoured by catfish.

Abstract

The application of biofilm biofertilizer is potential to improve soil fertility and increase plant yield. The research aimed to assess the use of organic fertilizer decomposed with biofilm biofertilizer to improve soil fertility and yield of upland kale in Vertisol. The field experiment was conducted in Vertisol at Jaten, Karanganyar, Central Java, arranged in a Randomized Complete Block Design with a single factor, which was organic fertilizer dose consisting of 0, 3, 6, 9, 12, 15, 18, and 21 ton.ha-1 organic with NPK fertilizer as comparison treatment. Upland kale seeds were planted in 15 x 15 cm plant spacing. The variables observed were total nitrogen, available P, exchangeable K, soil organic matter, pH, cation exchange capacity, leaf number, plant height, fresh and dry weight. The data obtained were analyzed using F test followed by Duncan Multiple Range Test (DMRT) 95%. The result showed that the organic fertilizer dose had a significant effect on all of the observed variables. Optimal doses of organic fertilizer to improve soil fertility and upland kale yield was 15 - 18 ton.ha-1. The highest yield of upland kale was observed in the treatment of 21 ton.ha-1 organic fertilizer (76.5 ton.ha-1), which was increased by 176% compared to control (34.7 ton.ha-1) and by 108.8% (45.78 ton.ha-1) compared to NPK treatments. The application of 3 ton.ha-1 organic fertilizer gave better yield of upland kale than NPK fertilizer.

Abstract

Study of Organic and Inorganic Acid Capabilities in Solubilize Phosphatic Rock‐P. Phosphatic rock has been used as phosphate fertilizer for along time and now being an alternative of P fertilizer. But its low solubility making them uneffective source of P for plant. Many attempt to increases their solubility has been done i.e. by acidulated it with organic and inorganic acid. Inorganic acid solubilize mineral P by acidification while organic acid by acidification and maybe chelating mechanism. The aim of this research is to study the effectivity of the two kind of acid, organic (citric acid) and inorganic acid (sulphuric acid) in solubilizing phosphatic rock‐P. Research has conducted in May – Oct 2007 at Soil Biology Laboratory, Gadjah Mada University, Yogyakarta. The experiment arranged in Completely Randomized Design with three level of sulphuric acid concentration (0.00 M, 0.02 M and 0.04 M), three level of citric acid concentration (0.00 M, 0.02 M and 0.04M) and three kind of phosphatic rock (Christmas Island, Ciamis and Madura) origin. Each of combination treatment replicated three times. A gram of each phosphatic rock was added to 50 ml of aquades in 150 ml erlenmeyer flask and shoke continuously at 200 rpm in reciprocal shaker. Water soluble‐P and pH were analysed at 0, 3, 6 and 9 day after incubation time. All data was analysed for anova at 95% level of significance and continued with DMRT if any significance differences. Research show that inorganic acid (sulphuric acid) solubilize phosphatic rock‐P stronger than organic acid, except for high content Al phosphatic rock, where the two kind of acid have equal P‐solubilizing capacity. Maybe, the high P‐solubilizing capacity of organic acid for high Al‐phosphatic rock caused by its ability in chelating Al. Keywords: Fosfat, batuan fosfat alam, asam sitrat, asam sulfat

Abstract

Title : The Inoculation of Sulfur Oxidizing Fungi on Phosphate Rocks Fertilizer  to Increase Their Available Phosphate and Sulfate. Phosphate rocks as an alternative sources of P fertilizer are cheaper than SP-36. The main problem was their low of total and available P that must be increased to make them more effective source of P for plants. Inoculate them with S oxidizing fungi will increase their available-P. The research aim was to study the potency of two S oxidizing fungi Aspergillus japonicus and Penicillium nalgiovensis to increase available-P of phosphate rocks. Experimental research done at the Lab. of Soil Biology and Lab. of Soil Chemistry and Fertility, Department of Soil Science, Faculty of Agriculture, UNS, Surakarta, at March – Mei 2008. The experiment arranged in completely randomized design with four factors i.e. the origin of elemental sulphur (from G. Welirang, East Java and from USA), the origin of phosphate rocks (Christmas Island, Ciamis and Madura), kind of inoculums fungi (A. japonicus and P. nalgiovensis) and inoculums densities (0; 106 and 107 spore/g of phosphate rock). Each treatment combinations were replicated three times. Fifty grams mixture of phosphate rocks, cassava solid waste, tapioca and rice bran was poured in 250 ml Erlenmeyer, sterilized with autoclave at 121 oC for 30 minutes, three times alternately in 5 days, then inoculated with fungus spores and incubated at field capacity in room temperature for 3 months. Samples were taken at 1, 2 and 3 months after incubation time for analysis of water soluble-P, soluble sulphate, pH and total fungus. Data analyzed statistically with F test and Duncan Multiple Range Test at 5% of level significance. The result show that the two of S oxidizing fungi Aspergillus japonicus and Penicillium nalgiovensis were be able to increases available-P of phosphate rocks, as well as soluble sulphate more than 200 % of control treatment. Penicillium nalgiovensis was more effective than Aspergillus japonicus. As P sources, phosphate rock from Christmas Island was better than from Ciamis and Madura, while elemental S imported from USA was better than local So from G. Welirang. The increase of inoculums densities and length of incubation times increase soluble P and sulphate. Keyword: phosphate rocks, S oxidizing fungi, soluble P and sulphate
