Abstract

The aim of this research was to study IAA content, nutrient uptake, growth and productivity of maize and peanut in response to application of biofertilizer. The research was conducted in a green house of Cikabayan IPB Farm, Bogor Agriculture University, Darmaga, Bogor, West Java. A completely randomized design was applied in single factor experiment for maize and peanut with 3 replications. The treatments consisted of 4 factors: I. Without fertilizer, II. 100% biofertilizer (dosage 100g/pot), III. 100% inorganic fertilizer, and IV. Combination of biofertilizer and inorganic fertilizer with 50% dosage. Biofertilizer was applied using compost enriched by Pseudomonas sp., Bacillus sp., Azotobacter sp., Azospirillum sp., Rhizobium sp, and P-solubilising bacteria. The dosage of inorganic fertilizer was 0.5 gfpot of Urea; 0.5 g/pot of SP-36; 0.375 g/pot of KCI for maize, and 0.125 g/pot of Urea; 0.5 g/pot of SP-36; 0.375 g/pot of KCI for peanut. Application of biofertilizer enhanced auxin content of maize by 73-159°/o, but not in peanut. The treatment also increased the uptake of N, P, and K of both plants by 2 to 35 times as compared to control plant. The production increased by 270% on maize and 66% on peanut due to application of biofertilizer. The result showed that application of compost enriched by microbial activator was able to supplement inorganic fertilizer for growth and production of maize and peanut.

Abstract

Plants can be used as phytoremediation agents to improve critical land due to gold mining activities. This experiment aimed to analyze the morphophysiological, anatomical, and histochemical responses of Brachiaria mutica, Cyperus kyllingia, Ipomea aquatica, Mikania micrantha, and Paspalum conjugatum in response to the application of heavy metals mercury and lead in the forms of Hg(NO3)2 and Pb(NO3)2 in hydroponic experiments and to determine the ability of these plants to accumulate both metals. Morphological responses were observed by measuring number of leaves and plant dry weight, and physiological responses were observed by analyzing photosynthetic pigments, while anatomical and histochemical responses were analyzed by microscopic observation to tranversal slice of roots and leaves. The results showed that the applications of Hg(NO3)2 and Pb(NO3)2 treatments caused decreases in number of leaves, plant dry weights, and photosynthetic pigments (chlorophyll a, chlorophyll b, and carotenoid). The treatments also decreased leaf thickness due to the decrease in the epidermis, but they caused the increases in exodermis and endodermis of the roots. Mercury and lead were accumulated in large amounts in the roots, but accumulation in the shoot was less. Histochemical observation showed that lead was found in the roots of all the plants, especially in endodermic tissue and the vessel, whereas in the leaves the two metals were detected in the upper and lower epidermis, mesophyll, and vessel. Among the five species tested, C. kyllingia and P. conjugatum were the most tolerant to Pb and Hg.
