introduction soil herbicides residue in agroecosystems is one of the important problems due to herbicides application. however herbicides residue in soil extend the period of weed control. nevertheless, it may persist longer than desired and injure subsequent crops in rotation. herbicides vary in their potential to persist in the soil. some herbicides such as sulfonylurea herbicides are very pe...

during winter 2004 and 2005, two field and glasshouse experiments were conducted to evaluate the response of 471 chickpea genotypes to ascochyta rabiei, as ascochyta blight (ab) disease in chickpea (cicer aurietimum). frequent rainfall at flowering and pod formation stages made favorite conditions conducive for the infection and symptoms expression. so, the genotypes with high level of toleranc...

environmental stresses such as drought have important effects on plant growth and development. in order to evaluate the effect of drought tolerance, 12 chickpea genotypes were treated with drought stress in hydroponic condition in greenhouses. treatments were a control and two stress treatments -3 and -6 bar that was created with polyethylene glycol in hydroponic condition. two weeks after the ...

Shifting the sowing time of chickpea plants from spring to autumn in arid and semi-arid regions Iran is unavoidable. To study feasibility this issue, 32 desi-type genotypes were planted Mashhad (as a temperate region) Jolgeh Rokh cold screen cold-tolerant genotypes. The results revealed that 100% 19% had survival range 76–100%. MCC918 MCC913 highest height (69 33 cm, respectively). biological y...

late-season drought is the major constraint reducing the productivity of chickpea. this experiment was carried out to study response of root and shoot characteristics in 12 chickpea genotypes to drought stress. two-drought stress levels (-3 and -6 bar) induced by peg 6000 and control in hydroponic condition at green house was performed. leaf relative water content (rwc), plant height, number of...

to determine the association between genetic parameters and traits in chickpea (cicer arietinum l.) genotypes, a field experiment was conducted with 17 chickpea genotypes using a randomized complete block design with four replications at the ilam agricultural and natural resources research center in the 2004 growing season. genetic parameters including genetic, environmental and phenotypic vari...

Little attention has been paid to the diagnosis of deficiencies of micronutrients such as zinc (Zn) and boron (B) and secondary nutrient such as sulphur (S) in rainfed systems. We evaluated Zn, B and S status of 1617 farmers’ fields in 14 districts of the semi-arid tropical India. Results showed that most of the soil samples were low to medium in organic carbon contents. Results also revealed t...

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...
