to study the effect of planting date, plant density and planting pattern on yield of corn (zea mays l) var. ksc 647 split plot factorial experiment in a randomized complete block design with four replications at bayranshahr lorestan province in crop year 2015 was conducted. factors examined included planting date in three levels: (25 may, 12 june and 29 june), density at three levels (60, 75 an...
To evaluate the phenological stages and yield of wheat cultivars in response to the change of planting date and application of paclobutrazol, a field experiment was conducted in two years, 2020-2021 and 2021-2022, in Izeh city located in the northeast of Khuzestan, Southwest Iran. The experiment had three replications in a split factorial randomized complete block design. The main factor includ...
هدف از انجام این مطالعه بررسی پاسخ دهی تغییرات دینامیکی ضربان قلب به اندوتوکسین در موش های دیابتی و مقایسه آن با موش های سالم است. به همین منظور آزمایش ها در دو فاز in vivo و in vitro بر روی موش های صحرایی نر نژاد sprague-dawley طراحی و انجام شدند. در فاز in vivo از سیستم تله متری برای بررسی تغییرات ضربان قلب در حیوان هوشیار استفاده شد. نتایج مطالعه نشان داد که تزریق اندوتوکسین با دوز (1mg/kg) ...
ABSTRACT Water management is an essential concept for water intensive crop such as maize dealing with water shortage under drought conditions. Maize production is ranked after wheat and barely in Fars province, Iran. Therefore, the present study was conducted to investigate the effects of planting methods by conventional and modified planters on maize growth and yield at different irrigation re...
Although safflower is known to be a cool-season crop, it is usually planted as a summer crop in Isfahan. Thus, an experiment was conducted in 2000 at the Agricultural Research Station, Isfahan University of Technology, to study the effects of date of planting on growth, yield components, and seed yield of safflower. Five planting dates (March 12, April 12, May 10, June 8, and July 12) and four ...
We have developed a N6-dimethylallyladenine (cytokinin) dehydrogenase-based microbiosensor for real-time determination of the family of hormones known as cytokinins. Cytokinin dehydrogenase from Zea mays (ZmCKX1) was immobilised concurrently with electrodeposition of a silica gel film on the surface of a Pt microelectrode, which was further functionalized by free electron mediator 2,6-dichlorop...
ett, 1999), planted early and at low populations; thus, relying on the sorghum hybrid to adapt to the growing Typical planting recommendations for dryland grain sorghum [Sorconditions by tillering. Research by Jones and Johnson ghum bicolor (L.) Moench] in the southern High Plains are to delay (1991, 1997) demonstrated that the optimum planting date, until soil water is adequate for crop establ...
Effect of different times and levels of nitrogen fertilizer application on growth and grain yield of spring wheat cultivar “Ghods” was studied during 1993-1994 growing season at Karkadj, Agricultural Experiment Station, College of Agriculture, University of Tabriz, using a split plot design with three replications. Main plots were assigned to five levels of N fertilizers (0, 40, 80, 120 and 160...

The appropriate planting pattern of safflower in summer planting might be different from the planting pattern suitable for spring planting, and this has not been determined under Isfahan environmental conditions. A field experiment was conducted in the summer of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plo...
