Abstract

Bacillus thuringiensis srv.toumanoffi is an indigenous endophytic rizobacteria from healthy soybean rizosphere capable of controlling bacterial pustule disease (Xanthomonas axonopodispvglycines). Rhizobacteria needs to be formulated to remain effective in storage and application. The aimed of this research was to obtain a stable bacterial formula in controlling bacterial pustule disease in soybeans. This research was designed in factorial in a randomized group consisting of 13 treatments with 3 replications. The Treatment was a combination of carrier material (peat, tapioca and coconut water+1% palm oil) and storage time (0, 2, 4, and 6 weeks). Soybean seeds were introduced with each Bacillus thuringiensis srv. toumanoffi formula before planting. The results showed that the formula Bacillus thuringiensissrv. toumanofi was relatively stable in suppressing the incidence and severity of bacterial pustule disease in soybean leaf. The best formula for controlling bacterial pustules was Bacillus thuringiensis srv. toumanoffi in peat, coconut water + palm oil and tapioca each 2 weeks storage.

Abstract

Elephant grass (Pannisetum purpureum) can grow in various types of land conditions and produces and is resistant to environmental stress. The predominant sand tin tailing conditions and poor nutrients cause limited plant growth above them. This research tested some kind of fertilizer treatment on sand tailing media after tin addition by using elephant grass plants. The results showed that the type of fertilizer had significant effect on the specific leaf area variant, the ratio of leaf area and the leaf weight ratio. Overall growth were greatly depressed on the 100% tailings treatment. Lime applied in conjunction with NPK fertilizer was not show the total leaf weight that was different from the addition of NPK alone. NPK fertilizers better influence the growth of elephant leaves in tin tailings than organic fertilizers. The best treatment was obtained on organic fertilization with NPK inorganic fertilization. The association of total dry weight of elephant grass with specific area of elephant grass leaf was only visible in organic fertilization treatment together with NPK inorganic fertilizer. In the best condition of elephant grass growth, the specific leaf area had a significant role to increase the total weight of the plant with the value of r2 = 0.864 or LDS will affect the total dry weight of elephant grass in the tailings medium with the addition of organic and inorganic materials NPK of 86.4 percent the remaining 13.6% increase in total dry weight was influenced by factors other than specific leaf area.

Abstract

Phosphorus is a macro essential nutrient for plants that are needed in large quantities third after Nitrogen and Potassium. Phosphorus acts as an activator of various plant metabolism enzymes and is a component of chlorophyll. Phosphorus is a necessary element in large amounts (macro nutrients), the amount of phosphorus in plants is smaller than nitrogen and potassium, but phosphorus is the key to plant life by absorbing phosphorus in the form of primary orthophosphate ions (H2PO4-) and secondary orthophosphate ions (HPO42-). In acid soils, the phosphate will be compounded in Al-P and Fe-P forms, whereas in alkaline soil, phosphate will be compounded with calcium as Ca-P forming a soluble complex compound. This research was conducted with the aim of evaluating the relationship and interrelations between the dynamics of phosphorus nutrients to some soil chemical properties on each acid soil profile horizon. This research was conducted in Laboratory of Soil Chemistry and Fertility Department of Soil Science and Land Resources Faculty of Agriculture, IPB. The soil samples used in this research were soil samples originating from the location of Neglasari Jasinga Bogor Village and Padasuka Village Maja Lebak District of Banten Province was taken per horison in soil profile. The results of the two land sites used showed that the dynamics of the availability of phosphorus nutrients. This dynamic was due to the presence of soil pH and aluminum solubility within each soil horizon. On the land profile of origin of Jasinga and lebak that the value of Al-dd would be high if the low soil pH value and available P value would be high if there was a decrease in soil pH value and the value of Al-dd soil.Keywords: acid soil, aluminum, phosphorus
