This research was aimed at understanding the corn plant using plastic covers. The above mentioned plant was grown in plastic covers that have colours (transparent, red, green, and blue) and without plastic covers. This research was carried out in the Faculty of Agriculture, IPB from the month of May to June 2008. It was implemented using the Completely Randomized Design with three repetitions. The results of the research show that light intensity was higher in the plant that was not enclosed in the plastic covers. Generally, the research shows that the corn plant that was in the plastic covers is better than that one without plastic covers. The use of a plastic cover helps increases the height of the corn plant and the leaves. Chlorophyll a and Chlorophyll b are higher in the corn plant that was not in the plastic covers. The results of the research also indicate that transparent and red plastic covers have better responses compared to plastic covers with blue and green colors.

ABSTRACT To increase the efficiency in the control of weeds, it is common the use of a mixture of the herbicides glyphosate and 2,4-D in the desiccation. This paper aimed to evaluate the residual effect of these two herbicides on the development of maize plants, in soils of different textures. The experiment was conducted in a greenhouse, in 2015, in a completely randomized design in a 2 x 2 x 7 factorial scheme, corresponding to two soils (Red Yellow Latosol and Quartzarenic Neosol), two herbicide application times (5 and 10 days before maize sowing) and seven doses of herbicides (recommended dose of glyphosate, recommended dose of 2,4-D; mixing the recommended doses of glyphosate and 2,4-D; two, ten and fifty times the recommended doses in admixture; and one control), with 4 replicates. After emergence of maize plants, the following variables were evaluated: phytotoxicity, plant height, chlorophyll a and chlorophyll b, shoot fresh and dry matter and root dry matter. In general, there was lower residual effect on the Red Yellow Latosol at all the doses of the herbicides and in the interval of 10 days between the desiccation and sowing.

The raised-bed soil is a land management technology in South Kalimantan. Adding Ameliorant to the raised-bed soil as an effort to increase the utilization of support for the cultivation land. Chlorophyll or leaf green substances found in all green plants that carry out photosynthesis. Ameliorant applications can increase the chlorophyll content of plants to optimize plant growth. This study aims to look at the effect of giving several types of ameliorant to the content of chlorophyll (chlorophyll-a, chlorophyll-b and total chlorophyll) and the growth of corn planted on raised-bed soil. This research is an experiment in the laboratory and a greenhouse. This research was conducted using a Completely Randomized Design (CRD) Single Factor with the treatment tested was the type of ameliorant soil without treatment (control - K), soil + agricultural lime (dolomite - C), soil + palm empty fruit bunch ash (S), soil + rice husk ash (P) and soil + coal ash (B). All treatments were repeated 5 (five) replications so that there would be 25 units of the experiment. The results showed that the application of ameliorant in raised-bed soil using dolomite and oil palm empty fruit bunches ash with a dose of 5 tons ha-1 affected the content of chlorophyll-a and total chlorophyll in the growth of corn planted in raised-bed soil materials.

The purpose of this research is to study interaction of humic substances extracted from subbituminus coal with P fertilizer on the chemical properties of Ultisol and crop production of corn (Zea mays L.). The experiment was designed in completely randomized design having 2 factors (4 x 4) with 3 replications. The first factor was dose of humic substances (A) which consists of 4 levels (A1 = 0 ppm, A2 = 400 ppm, A3 = 800 ppm, and A4 = 1200 ppm). The second factor was level of fertilizer P (B) (B1 = 100% recommendation, B2 = 75% recommendation, B3 = 50% recommendation, and B4 = 25%). The result showed that : 1) There is no interaction between humic substances and P fertilizer on the chemical nature of Ultisol and crop production of corn (Zea mays L.) 2) Use of humic substance for 800 ppm with some level of P fertilizer could improve some chemical properties of Ultisol such as decreased in content of Al-exch by 0,38 me/100 g soil, increased in P-available by 22,16 ppm, CEC by 8,42 me/100 g soil and P nutrient by 0,10 %, as well as corn yield by 25,67 g/pot compared to soil without humic substances 3) The use of SP-36 for 50 % with some level of humic substances increased in plant height by 26,58 cm, P nutrient by 0,11 %, and the use of 75 % SP-36 increased corn yield by 5,84 g/pot compared to 25% of P recommended.Keywords : humic subtances, subbituminus coal, P fertilizer.

The Research about the effects of extract from the invasive plant leaves of Mikania micrantha Kunth. and non-invasive plant leaves of Cosmos sulphureus Cav. on the germination of corn (Zea mays L.) has been conducted in July 2016 in Plant Physiology and Tissue Culture Laboratory, Biology Department, Mathematics and Natural Science Faculty, Andalas University, Padang. The aim of this research was to compare the effect of extract from the leaves of plants M. micrantha and C. sulphureus with several concentrations on the germination of corn. The research used experimental method with Completely Randomized Design (CRD) on Nested, 9 treatments and 4 replications. The treatments were factor A (type of plants, a1= Mikania micrantha and a2= Cosmos sulphureus) and factor B (leaf extract concentration, b0= 0%, b1= 20%, b= 40%, b3= 60%, b4= 80%). The results showed that the extract of the leaves from M. micrantha affected to reduced the fresh weight plants at concentration of 20%, where as in leaf extract of C. sulphureus affected to reduced the fresh weight plants at concentration of 40%.

Scientific Name

Zea mays L. is the scientific name for corn which is containing antioxidants such as carotene. Germination of corn can improve nutrition from food due to enzyme activity. This study aims to determine the effect of germination time on total phenol, carotene and antioxidant activity in corn sprouts flour. In this study, the research design used is Completely Randomized Design with five of germination time such as 24, 30, 36, 42 and 48 hours with each treatment was repeated three times. The corn sprouts obtained were then tested for total phenol, carotene and antioxidant activity. The result showed that germination time had a significant effect on total phenol, carotene and antioxidant activity (IC50 and ?-carotene bleaching). The best germination time obtained is 48 hours that had a total phenol level of 11.35 mg/100g, a total carotene level of 1.38 mg/100g, an antioxidant activity (IC50) of 1.32 mg/ml and an antioxidant activity (?-carotene bleaching) of 0.53 mg/ml.

Sugarcane (Saccharum spp. hybrids) is moderately sensitive to salinity and the effects on plant performance vary according to stress level and genotype. This study aimed to evaluate the effect of salt stress induced by application of different NaCl levels in the irrigation solution on plant height, indirect index of chlorophylls (SPAD), and macronutrients concentration (N, P, K, Ca, Mg and S) and Na in leaves of two sugarcane varieties: CP 72-2086 and Mex 69-290. The experiment was set in a completely randomized design with a 2×5 factorial arrangement. The study factors were sugarcane variety (CP 72-2086 and Mex 69-290) and NaCl concentration (0.0, 71.8, 143.6, 215.4 and  282.7 mM NaCl). Salinity as a single factor negatively affected plant height, SPAD units and N and P concentration in leaves; Ca concentrations increased, while K, Mg and S remained unaffected by the tested NaCl levels. Mex 69-290 grew higher and concentrated greater levels of N and K. Interactions of factors showed that salinity reduced growth in both varieties, but this reduction was more pronounced in CP 72-2086. SPAD units were also significantly reduced by salinity in both varieties. Concentrations of N and P in leaves decreased in both varieties in response to NaCl, while those of K and Ca increased in Mex 69-290. Concentration of Na was higher in Mex 69-290 which exhibited better performance than CP 72-2086. Sodium concentrations in leaves increased in direct relation to the tested NaCl concentrations. Mex 69-290 reached higher concentrations of Na in leave tissues but displayed better health than CP 72-2086. Thus, the variety Mex 69-290 showed more efficient Na-tolerance mechanisms related to Ca and K concentrations, and an indirect chlorophyll index better than CP 72-2086.
