In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
One of the effective indirect selections methods for improving grain yield and its components is the selection index. In order to develop a suitable selection index for simultaneously increasing yield and its related traits, 100 sunflower inbred lines from different geographical origins were evaluated in randomized complete block designs with three replications at Urmia University in 2015 ...
in order to evaluate the waterlogging stress effects on yield and yield components of rapeseed, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental stage (seedling, stem elongation, flowering and g...
the experiment was aimed at investigating the effects of defoliation (i. e. amanipulation of source size) at different times and with different intensities on yield, grain protein content and remobilization of dry matter from shoot to grain under various levels of soil moisture and nitrogen in winter wheat. two separate field experiments were conducted simultaneously under water stress vs irrig...
This study was conducted to determine the yield response factor (Ky) of wheat with respect to deficit irrigation at different growth stages. The experiment was conducted in Shahrekord in three crop growing seasons using randomized complete blocks design with 3 replications. Treatments consisted of five levels of deficit irrigation: E0 (full irrigation), E1 (85%), E2 (70%) and E3 (55%) of potent...
Salinity and flooding are as two very important factors of soil degradation. They often occur together and cancause severe damage to plants. However, plant response to environmental stresses may vary with growth stage atwhich exposure occurs. A pot study was conducted in 2005-2006 in northern Aq Qala (northern Iran) to studycombine effects of waterlogging and soil salinity at different growth s...
Planting density, through its impact on the level of available environmental factors may have significant impacts on grain yield in safflower (Carthamus tinctorius L.). In order to investigate the impacts of plant density on grain yield, yield components and growth characteristics of safflower, a randomized complete block design field experiment with four replicates was conducted in spring-summ...
In order to study the effect of terminal drought stress on yield and yield components and some physiological traits of wheat genotypes, a field experiment was conducted at the Research Farm of Agricultural College of Shiraz University during 2010-11 growing season in a split plot arrangement based on randomized complete block design with three replications. Main plots were assigned to irrigatio...
