Abstract: The poor agronomic practices, such as seeding rate and inappropriate plant population are the major reasons for low productivity of soybean. A field study did to determine the appropriate row and plant spacings for Soybean productivity and profitability at Metema and west Armachiho districts. Treatments were arranged to five rows (30, 40, 50, 60 and 70 cm) with three plant spacings (5, 10 and 15 cm) comparing with the blanket recommendation (40 cm x 10 cm and 60 cm x 5 cm) and laid out in randomized complete block design with three replications. The Afgat variety was used as planting material and 121 kgha-1 of NPS fertilizer was applied at sowing time. The combined results indicated that; days to 50% flowering, number of branches plant-1, length of productive node, number of seeds pod-1were significant, whereas days to 90% physiological maturity, plant height, number of pods plant-1, hundred seeds weight and grain yield were highly significant (p < 0.01) and affected by the interaction effects of inter and intra row spacings. The highest grain yield (3831 kgha-1) and net benefit (50,650 ETB/ha) were obtained from the combination of 40 cm row spacing with the 5 cm plant spacing. Whereas, the blanket recommendation (40 cm x 10 cm and 60 cm x 5 cm) gave 3556 kgha-1and 3519 kgha-1, respectively. Therefore, 40 cm the row with 5 cm plant spacing is suggested to be promoted for Soybean production on the low land areas of northwestern Gondar, Ethiopia.

Abstract: The present work aims to characterize the geochemistry of the beach sands along the Mediterranean Coast from Al Kuwifia to Tolmeita, Northeast Libya. The study is based on 36 samples collected from the studied beach sands from 12 stations. Three samples of each station. The samples were taken from a depth of 30 cm. The statistical treatment of the obtained data involves descriptive statistics and correlation matrix. The data include 12 major oxides and 27 trace elements, as quoted in Tables. The major elements are generally considered somewhat mobile during weathering, transportation, and post-depositional processes. The major oxides CaO and MgO are the main constituents of the carbonate minerals; calcite and aragonite. SiO2 is mainly in the form of quartz. Sometimes a high quotient of SiO2 together with the oxides; Al2O3, K2O and partly of Na2O, TiO2 and Fe2O3 are essentially allocated within the structure of the feldspars. Part of Na2O and the content of Cl belong mainly to halite. Part of Fe2O3 and TiO2 may be accommodated as iron oxyhydroxides. Part of CaO and the content of SO3 are allotted within the gypsum structure. Ba, Sr, Th, U and Rare Earth Elements (REE) are basically controlled by the carbonate fraction, while Cu, Zn, V and Cr are strongly correlated with Al2O3.

Abstract: In the context of the molecular life of organisms, genomics helps to understand how genetic information is encoded and how it is implemented at the molecular level, ensuring the vital activity and characteristics of each organism. In the structure of genomes, DNA sequences, the arrangement of genes, regulatory elements and other molecules that make up the genome are studied. Gene functions determine how genes encode proteins and other molecules, their role in metabolism, growth, development and interaction with the environment. Studying changes in the genomes of different species, which helps to understand the origin and adaptation of organisms. The use of modern sequencing, analytics and bioinformatics methods is important for the rapid and accurate study of the molecular basis of life. Molecular mechanisms help to uncover processes such as replication, transcription and translation that underlie the functioning of cells. Overall, informative genomics provides a deep understanding of the molecular basis of life, allowing us to trace how genetic information controls all aspects of the existence of organisms - from the simplest bacteria to complex multicellular creatures. Informative genomics is the foundation for maintaining the life of an organism at the molecular level, the development of biotechnology, genomic medicine, ecology and evolutionary research.
