Abstract :
In order to study the effect of biological fertilizer and microelements on chlorophyll content, protein percentage and grain yield of chickpea (Cicer arietinum L.) as affected by drought stress condition an experiment carried out in factorial based on complete block design with three replications in 2014 at Agricultural Research Station of Roudehen of Islamic Azad University in Damavand. Treatments were three levels of drought stress: normal irrigation (control), stress at flowering stage and stress in early stages of grain filling and the second factor was four levels of biological fertilizer and microelements including control, biological fertilizer (Rhizobium), microelements, Rhizobium + microelements. Results showed that drought stress had significant impact on chlorophyll content, protein percentage and grain yield. Control treatment (normal irrigation) produced the highest chlorophyll content, protein percentage and grain yield. Impact of biological fertilizer and microelements on all traits were non-significant except protein percentage and grain yield. The interaction effect of drought stress and biological fertilizer and microelements for protein percentage and grain yield was significant.
