ABSTRACTThis research was conducted in the Analitic laboratory of Palangka Raya Univercity and in the screenhouse of Agriculture Cultivation Department, Palangka Raya Univercity. The purpose of thisexperiment was to determine the effect of dolomit and chicken manure to some soil chemicalproperties of acid sulfate soil and growth of Maize Crop (Zea mays L.). The research was arranged inComplete Ramdomized Design with two factors and three replications. The first factors were level ofdolomit with three levels namely 0 ; 1,5 ; 3,0 times exchangeable alumunium. The second factors werelevel of chicken manure with three levels namely 0, 6 and 12 t ha-1. The results showed that theinteraction between dolomit and chicken manure significantly affected increasing the soil pH anddecreasing exchangeable alumunium. The combination level of dolomit in level 1,5 timesexchangeable alumunium with application of 6 ton.ha-1 chicken manure will be optimum increasingthe soil pH and decreasing exchangeable alumunium. The application a single factor of dolomit notsignificantly affected P-availabilityand growth of Zea mays (plant height, number of leaf and area leafindex) in age 2, 3, 4, 5, 6 weeks after planting. The application of chicken manure only significantlyaffected increasing P- availabilityand growth of Zea mays (plant height, number of leaf and area leafindex) in age 2, 3, 4, 5, 6 weeks after planting. Optimum dosage of chicken manure was 6 t ha-1.Keywords: sulfate soil, dolomite, soil chemical, chicken manures.

Abstract—A glasshouse experiment was conducted to elucidate the effectiveness of elemental sulfur as a soil acidulates on solubility of soil Fe and it’s uptake by corn (Zea mays L.). Four rates of elemental sulfur, 0, 0.5, 1 and 2 g S kg-1 soil, incubated for 0, 20 and 40 days before corn plantation. The result showed that with one unit increase in S application rate the soil pH decreased about 1.52 units and the solubility of the Fe was significantly increased. The concentration of Fe in corn leaves and stem were increased with soil acidification from the background of 7.03 to 5.42 due to elemental sulfur application rate of 1 g S kg-1 soil. However, further soil acidification decreased Fe concentration in corn. Overall, application of elemental sulfur at a rate of 0.5 g S kg-1 soil is recommended to enhance corn performance by 45 percent without the risk of Fe toxicity for corn and the minimum Fe export to groundwater.

Chamber Experiment

Banding of urea in corn (Zea mays L.) production is restricted by toxic conditions from urea hydrolysis, but higher urea rates could reduce application cost. A growth chamber experiment and a field experiment were conducted to study toxicity of banded urea when applied with triple super-phosphate (TSP). In the growth chamber experiment, surface samples from a Ste. Rosalie clay (Humic Gleysol), a Chicot sandy clay loam (Grey-brown Podzol), and an Uplands sandy soil (Humo Ferric, Podzol), were used. The field experiment was conducted on a Ste. Rosalie clay, a St. Bernard loam (Eutric Brunisol), and a Chicot sandy clay loam soil. In the growth chamber experiment, banded urea increased soil pH to 7.2–7.5 at a distance of up to 4 cm from the fertilizer band, and NH3 concentrations were as high as 2.1 mM at 2 cm from the fertilizer band after 20 d. The high pH and NH3 concentrations from urea hydrolysis inhibited corn root and seedling growth. Banding TSP with urea reduced soil pH increases from urea hydrolysis and reduced NH3 concentrations. Root weights increased with added TSP in urea bands. In the field experiment, banding urea at > 40 kg N ha−1 reduced plant density and shoot dry weight in early growth stages. Banding TSP with urea increased seedling growth in all soils. Maximum rates of urea compatible with increased corn yield could be increased from 40 to 80 kg ha−1 when banded with TSP.

Banding Patterns

A procedure for chromosome banding in triticale has been shown to be equally effective on maize, Zea mays L., root tip chromosomes. Stocks of known knob constitution were used to demonstrate that differentially stained regions of C-banded mitotic chromosomes corresponded with knobs. The large knob and prominent chromomeres of abnormal chromosome 10 were also differentiated, as was the centric heterochromatin of B chromosomes. However, the large distal heterochromatic portion of the B was not differentiated by the procedure.
