In this study, an individual tree crown ratio (CR) model was developed with a data set from a total of 3134 Mongolian oak (Quercus mongolica) trees within 112 sample plots allocated in Wangqing Forest Bureau of northeast China. Because of high correlation among the observations taken from the same sampling plots, the random effects at levels of both blocks defined as stands that have different ...

The low production of eggplant plants in Indonesia is due to the fact that business these less intensive and still traditional without cultivation, especially use fertilizers so it can support growth yield plants. Increasing yields also be done by means fertilization using right dose. main function fertilizer provide or add nutrients which are sometimes available small quantities, even not at a...

Increasing the area of arable oilseed land, particularly rapeseed, and the important role of potassium in yield and oil content, especially in calcareous and high pH soils, need to more knowledge about plant nutrition requirement. In this study, the effect of sources and different levels of potassium fertilizers on some quality and quantity characteristics on canola yield were assessed by combi...

The present study was initiated to determine whether isolates from soil and roots of paddy plants can affect the plant’s growth productivity. conducted answer question, “Can rice be grown when NPK doze is reduced?” This aims apply methanotroph bacteria on production lowland rice. research field carried out in fields Amparita Village, TelluLimpoe District, Sidenreng Rappang Regency, South Sulawe...

In applied entomological experiments, when the response is a count-type variable, certain transformation remedies such as the square root, logarithm (log), or rank transformation are often used to normalize data before analysis of variance. In this study, we examine the usefulness of these transformations by reanalyzing field-collected data from a split-plot experiment and by performing a more ...
