The population density of Hoplolaimus magnistylus, a lance nematode, in cotton was determined at planting, mid-season, and harvest during the 1995 and 1996 growing seasons for a Poinsett County, Arkansas field. Nematode populations increased from planting to harvest in 1995 but declined in 1996. Application of aldicarb at planting at rates of 0.59 or 0.84 kg a.i./ha did not influence either nem...

To understand the effects of effective microorganisms (EMs) containing multiple strains on microbes and nutrients in kiwifruit planting soil, EMs prepared with four different strains were added to kiwifruit planting soil monthly from April to August. The counts of bacteria, fungi, actinomycetes, and total microbes were determined. The pH, total nitrogen (TN), alkali-hydrolyzable nitrogen (A-N),...

in order to study the effect of harvesting time on yield of rapeseed cultivars, this research work was carried out at paddy fields of rice research institute of iran in rasht andamol during 2005-2006 and 2006-2007 cropping seasons. the experiment was conducted in a split plot based on randomized complete block design with three replications. four rapeseed cultivars including hyola 308, hyola 40...

In order to investigate the effect of planting method and sugarcane residue compost fertilizer on morphological and physiological traits and grain yield of corn, a field experiment using a split-plot arrangement was accomplished in a randomized complete block design with four replicates in Mian-Ab, Shooshtar, south-west Iran in summer 2018. Experimental factors included four planting methods (o...

In order to study the effects of nitrogen application rate and timing on grain yield, phyllochron and leaf appearance rate of corn (Zea mays L.), an experiment was conducted as split plot based on randomized complete block design with three replications at the Research Farm of University of Mohaghegh Ardabili, Ardabil, Iran during 2009 growing season. Nitrogen rates were arranged in main plot w...

  Using growing degree days (GDD) for expression of duration of plants’ developmental stages is preferred over calendar time. Therefore, determination of GDD and zoning of regions is very important for on time and correct agronomic practices and also for better land use. To determine the required GDD for developmental stages of spring safflower cultivars, the data obtained from planting-date ex...

The phenomenon of sleep is an active nervous and biologic rhythm, which is under influence of neurotransmitters of central nervous system. In this study, the influence of serotonergic system on sleeping time have been assessed by agonist-antagonist drugs using two methods of induction and non-induction behavioral and electrophysiology. The method used for measurement of total sleeing time was A...
