Abstract

Sterilisasi dan komposisi media merupakan faktor penentu dalam menghasilkan inokulan mikoriza yang berkualitas. Penelitian ini bertujuan untuk mendapatkan kualitas inokulan konsorsium FMA dan MHB yang terbaik dengan merekayasa media tanam dan metode sterilisasi. Percobaan telah dilakukan di rumah kaca menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri atas dua faktor perlakuan. Faktor pertama adalah sterilisasi media yang terdiri atas: (1) sterilisasi melalui pencucian dengan air, (2) sterilisasi menggunakan autoklaf, (3) sterilisasi dengan NaOCl, dan (4) sterilisasi dengan irradiasi gamma. Faktor kedua adalah komposisi media yang terdiri atas: (1) 100% zeolit, (2) 75% zeolit : 25% arang sekam, dan (3) 50% zeolit : 50% arang sekam. Hasil penelitian menunjukkan bahwa terdapat interaksi antara sterilisasi dan komposisi media terhadap jumlah spora MA, namun tidak berpengaruh terhadap nisbah pupus akar sorgum. Sterilisasi media secara mandiri berpengaruh terhadap populasi MHB. Perlakuan sterilisasi irradiasi gamma + komposisi media 75% zeolit : 25% arang sekam merupakan perlakuan yang cenderung lebih baik dalam meningkatkan jumlah spora MA, populasi MHB, dan nisbah pupus akar sorgum.

Abstract

Potato cyst nematode (PCN) is known as organism that could suppress the growth of potatoes and it has been found in West Java. Controlling of PCN by the use of chemical agents has been reduced, hence the use of biological agents such as soil fungi is one of the alternatives. Arbuscular mycorrhizal fungi (AMF) has a potential to be used as a controlling agents. However, the information about it?s effect on nematode, especially in Indonesia is limited. The objectives of this study were to isolate the indigenous AMF from potatoes plantation in a high land at Pangalengan district, West Java, to be used as an agents for controlling nematodes. AMF isolates were cultured and propagated to be used in the test of AMF effectiveness in controlling PCN in a glasshouse. Results showed that AMF at the rate of 150 spores/pot reduced the PCN parameters in term of numbers of juveniles II, fe-males and cysts. The mechanisms of AMF in reducing PCN activities was more likely because of the pro-duction of antifungi isoflavonoid that increased as increasing the rate of AMF spores. The experiment in general showed the successful results in explaining the potential use of AMF as bio-control agents of PCN.  Keywords: Arbuscular Mycorrhizal Fungi, Potato Cyst Nematode

Abstract

The productivity of potatoes in Indonesia is relatively low and unstable caused by unsuitable enviromental and soil conditions and bad cultivation system. This research was conducted to study the effect of NPK fertilizer dosages and soil order to soluble K, K Uptake, and yield of seed potatoes (Solanum tuberosum L.). The experiment design used a factorial randomized block design with two factors and three replication. The first factor was NPK fertilizer dosages with five levels (0, 25, 50, 75, 100% recomendation dosages) and the second factor was soil orders with two levels (Andisols and Inceptisols). The results of experiment showed that the interaction effect between NPK fertilizer dosages and soil orders had significantly effect to soluble K and K Uptake. There were independent effect of NPK dosages to diameter of potatoes tuber and independent effect of soils order to yield of seed potatoes. Andisols with 25% NPK and Inceptisols with 50% NPK were the best combination treatment to increase soluble K while treatment Inceptisols with 25% NPK was the best combination treatment to increase K Uptake. Dosages of 25% NPK was the best treatment to increase diameter of potatoes tuber while Inceptisols was the best treatment to increase yield of seed potatoes.Keywords : NPK Fertilizer Dosages, Andisols, Inceptisols, Potassium, Potatoes

Abstract

Hydroponics is one of the urban farming techniques that can be used to improve crop yield. Nowadays, the supply of all nutriens in hydroponics, particulary phosphate only derived from inorganic fertilizers. Application of arbuscular mycorhiza fungi (AMF) as bioagent may help plants to fill its nutrient need, especially phosphate. This study aimed to find out the best concentration of phosphate fertilizer to be applied to the hydroponic Ebb-flow system model. The stage was to test several vegetable plants with various concentrations of phosphorus (0, 20, 40, 80 ppm) on the Ebb-flow hydroponic system. Vegetables used were romaine lettuce, red lettuce, and kale. Interaction was found between vegetables and the variety of phosphate concentrations and the root colonization by AMF, and phosphate uptake. The AMF applications on the hydroponic Ebb-Flow system model reduced phosphate fertilizer need by 40 ppm (50%), on red lettuce 0 ppm (100%), and on kale 20 ppm (25%). Besides lowered phosphate doses, such applications also increased the plant yield.

Abstract

ABSTRACTContinues phosphate fertilization as well as organic matter amendment can increase cadmium concentrationin soil and induce more cadmium uptake by plants. Pytoremediation using non edible plant such as ramie(Boehmeria nivea L. Goud) is cheap and effective method to extract Cd from Cd-contaminated soil. Since inplant tissue Cd is bound in phytochelatin peptide which contains nitrogen and sulphur, the objective of thisgreen house experiment was to assess the influence of nitrogen fertilizer in form of urea on cadmiumuptake, nitrogen and sulphur concentration in shoots as well as shoot dry weight of 60-day old ramiegrown in cadmium-contaminated soil. The experiment was set up in a Split Plot Design with two treatmentsand three replications. The main plot was cadmium levels (0, 10 and 15 mg kg-1) and subplot was urea level(0, 5.0 and 7.5 g pot-1). The result showed that the increase of cadmium concentration in soil enhanced itsconcentration in ramie shoot regardless of urea levels. However either cadmium or urea did not changesulphur concentration in ramie shoot. Urea of 7,5 g/pot increased shoot dry weight but adding CdCl2.H2O of15 mg/kg did not change shoot dry weight. This experiment demonstrated that ramie was able to grow inrelatively high level of soil cadmium, and higher cadmium uptake by ramie shoot was not followed by anincrease in nitrogen as well as sulphur uptake.Keywords: Cadmium, Urea, Nitrogen, Sulphur, Ramie.
