Abstract

The objective of the research was to determine the effect of glyphosate herbicides on growth and yield of corn. This experiments was conducted at Sindang Barang Farm, Bogor from April to August 2013. This experiment used a Randomized Block Design with one factor namely dose of active ingredient glyphosate herbicide. The experiment consisted of 5 treatments such as control, and herbicide with doses 3, 4, 5, and 6 l ha-1. Plot size was 4 x 4 m, with plant spacing of 70 x 20 cm. Plots were treated on week before planting. Growth and yield of corn were influenced by herbicide treatments. Herbicide treatment at doses of 4 l ha-1 to produce seed growth, number of leaves, plant height, and leaf area the highest compared with other treatments. Similiar results also occur in the yield parameters of corn. Increased herbicide doses above 4 l ha-1 lower the better outcomes observed that variable growth and yield of corn. Based on glyphosate residue analysis indicated that each treatments contained residues of glyphosate. Herbicide treatment doses of 6 l ha-1 showed the highest residual value compared with other treatments. Based on glyphosate residue analysis in this research is still below the minimum limits of residue.

Abstract

ABSTRACTResearch to study performance of agro-morfology and genetic parameters of twelve rice genotypes at lowland rice irrigation was conducted at  Giripeni, Kulon Progo, Yogyakarta, during the wet season of November 2011 to February  2012. Twelve rice genotypess, namely Inpari 1, Inpari 2, Inpari 3, Inpari 4, Inpari 5, Inpari 6, Inpari 7, Ciherang, Dodokan, Silugonggo, Situ Bagendit, and IR64  were arranged in a randomized complete block design in three replications. Seedling of 15 days was planted in legowo 4:1, with one seedling per hill, spacing of 25 x 12,5 x 50 cm, in plot size of 5 x 10 m2. Time application and dosage of fertilizer were :1) Three days before planting with 2 t/ha organic, 2) Five days after planting with 300 kg/ha Phonska,  3) At 21 days after planting with 100 kg Urea/ha; and 4) At  35 days after planting with 100 kg Urea/ha. Data indicated that Inpari 3,  Inpari 5 and  Inpari 1 yielded  7.55; 7.44; and 6.98 t ha -1 respectively, and significantly higher than that of the best check variety Ciherang (6.26 t ha-1 ). Broad genetic variabilities were found for grain yield, panicle number per hill, filled grain per panicle, and total grain per panicle. High heritability estimate was found for 1000-grain weight, filled grain per panicle, total grain per panicle, panicle number per hill,  plant height, and maturity. Genetic and phenotypic correlation between filled grain per panicle and yield,  total grain per panicle and yield, and panicle number per hill and yield showed significantly different.Key words : agro-morphology, genetic parameter,  rice genotype, lowland irrigation

Abstract

ABSTRACTTea is multiplied either through generative or vegetative propagation systems.  Vegetative propagation is limited by several factors such as poor survival rate at nursery due to poor root formation of some clones and seasonal dependent rooting ability of cutting, however root system plays an important role in regulating of water uptake and absorb nutrient from the soil.  Root formation was believed under genetically control, therefore the objective of this research is  to characterize genetically the adventitious root of some tea clones. Seven clones were explored to study the adventitious root formation through the improvement of rooting media. The result showed that (1) improvement of root quality of tea through adding rooting media with plant growth  regulators seemed difficult to be implemented, (2). Rooting of tea cutting is under genetic control, (3) effort to improve root quality of tea through breeding approach looked visible in the future.Keyword : assamica tea, root, characters

Abstract

ABSTRACTBlack rice starts to be consumed as functional food due to high anthocyanine content which functioned as an antioxidant. The different in an existing name is predicted due to the pericarp color differences which are from light to heavy black.  It is therefore that morphological characteristics observation of pericarp color is required. This study aimed to identify genetic variability of 11 Indonesian local cultivar of black rice based on pericarp color parameters and total anthocyanine content, even their correlations. L*,  a*, b* color parameters were observed using Chroma Meter -  Konica Minolta – Minolta CM-2006, and white standard color was used for calibration, whereas total anthocyanine content was measured based on absorbent value of grinded rice grains using 535 nm wavelength of spectrophotometer. Color parameters and total anthocyanine content data were analyzed using analysis variance to estimate Genetics Variability Coefficient and cluster analysis to know the similarity among these local cultivars of black rice. The result showed that b* color variable and total anthocyanine content indicate broad genetic variability, whereas L* and a* color variables depict narrow genetic variability. There were 3 different groups of black rice based on   L*, a* and b* color parameters and total anthocyanine content. These were Cempo ireng; Banjarnegara, Banjarnegara-Wonosobo, Magelang berbulu, Magelang tak berbulu, Nusa Tenggara Timur and Pari Ireng; and Sragen, Jlitheng, Bantul and Melik groups. Positive significant correlation was observed between L*, a*, b* color parameters, and there was negative significant correlation between total anthocyanine content and L*, a*, dan b* color parameters. Key words: genetic variability, pericap colour parameters, total anthocianin content, local black rice

Abstract

The area of dry land for plantation cultivation is limited, so  peatland would be an alternative development. Adaptation of plant oil palm on the long inundation need to be investigated. This study aims to determine the growth response of oil palm seedlings in peat with some duration of flooding. The research was conducted in the experimental farm of the Faculty of Agriculture, University of Musi Rawas at an altitude of 110 m above sea level on March to June 2014. This study used a randomized block design (RBD) consists of six treatments and four replications. Treatment includes without flooding, duration of flooding 10, 20, 30, 40 and 50 days. The results showed that oil palm seedlings can survive up to 50 days of flooding. Long flooding inhibits the growth of plant height, number of leaves, reducing the amount of leaf chlorophyll. flooding also causes morphological changes in the root of the formation of adventitious shoots.

Abstract

Study of carbon dioxide emissions in different types of peatlands use in Central and West Kalimantan has been conducted in January-June 2006 and January-April 2007. The study represents 4 types of land use in Central Kalimantan as treatment: 5 years for chinesse cabbage, 10 years for chinesse cabbage, 5 years for sweet corns, and 10 years for sweet corns. As for the treatments in West Kalimantan, they include corn field, Aloe vera field, oil palm plantation, and rubber plantation. Carbon dioxide was measured using infrared gas analysis (model EGM-4, PP systems, Hitchin, UK). In Central Kalimantan, the highest CO2 is emitted from sweet corn plants (arable land for 10 years) by 0.79 g CO2/m2/hour, chinesse cabbage plants (for 5 years) by 0.73 g CO2/m2/hour, chinesse cabbage plants (for 10 years) by 0.67 g CO2/m2/hour and, the least, sweet corn plants (for 5 years) by 0.41 g CO2/m2/hour. The highest CO2 emission from West Kalimantan is released from rubber plants at 1.22 g CO2/m2/hour, followed by palm oil plants by 0.96 g CO2/m2/hour, Aloe vera plants by 0.68 g CO2/m2/hour and corn plants by 0.35 g CO2/m2/hour. Groundwater table depth are the most important factors among other factors that influence CO2 emissions. Groundwater table depth indicated a positive correlation with CO2 emissions in all types of peatlands use. C-organic production of sweet corn plants at 11.66 t C/ha/year is higher than that of chinesse cabbage plants at 1.64 t C/ha /year. Corn plants produce organic-C was 11.66 t C/ha/year, equivalent to the amount of loss of C through CO2 emissions by 11.29 t C/ha/year.Keywords: peat, types of land use, carbon, CO2 emission
