abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
dryland winter wheat (triticum sativum l.) generally grown in rotation with fallow or chickpea (cicer arietinum l.) constitutes a major crop in the west region of iran. information is limited on the success of more intensive dryland cropping systems while applying conservation tillage management. an experiment was conducted to determine the effect of five tillage systems on soil physical proper...
This study was conducted to evaluate the performance of different herbicides options for weed control in chickpea and their residual effect on bread wheat performance in crop rotation under rainfed conditions. The experimental design was randomized complete block with four replications conducted in Mahidasht Agricultural Research Center located in Kermanshah province, Iran during 2018-2019 and ...
Cicer arietinum L. (chickpea) is the world's fourth most widely grown pulse. Chickpea seeds are a primary source of dietary protein for humans, and chickpea cultivation contributes to biological nitrogen fixation in the soil, given its symbiotic relationship with rhizobia. Therefore, chickpea cultivation plays a pivotal role in innovative sustainable models of agro-ecosystems inserted in crop r...
in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...
this study was conducted to investigate economic aspect and some soil properties in different crop rotations of wheat in dryland conditions in sararood - kermanshah during six years 2006-2012. the experiment carried out based on randomized complete block design (rcbd) with four replications in two neighbor sites. treatments were wheat-wheat, fallow - wheat, chickpea-wheat, vetch-wheat and saffl...
Grain yield in wheat is influenced directly and indirectly by other plant characteristics. One of the main goals in wheat breeding programs is increase of grain yield. Considering the role of crop rotation in increasing grain yield, and in order to study the difference between crop rotations for wheat yield and yield components (Darya cultivar), an experiment was conducted with six rotation tre...
To evaluate the resistance of promising chickpea ecotypes to freezing temperatures, an experiment with eight promising cold tolerant chickpea was performed. The ecotypes consisting of 4301, 4322, 4360, 4361, 4366, 4380, 4715, 4816 along with a sensitive one (304) were sown in pots at natural conditions. All the chickpea ecotypes were exposed to freezing temp eratures at controlled conditions d...
Chickpea (Cicer arietinum L.) is an important food and rotation crop in many parts of the world. Cold (freezing and chilling temperatures) and Ascochyta blight (Didymella rabiei) are the major constraints in chickpea production. The effects of temperature stresses on chickpea susceptibility and pathogen aggressiveness are not well documented in the Cicer-Didymella pathosystem. Two experiments w...
introduction crop sequencing with a particular arrangement in a 2-3 or more yearly period is known as crop rotation. considering crop diversity and soil fertility crop rotation is essential because it prevents soil degradation which is a result of sequential cultivation of one crop causing nutrients imbalance, exudation of different compounds and antibiotics from crop roots. determining crops s...
