drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

Accurately predicting total electron content (TEC) during geomagnetic storms is still a challenging task for ionospheric models. In this work, neural-network (NN)-based model proposed which predicts relative TEC with respect to the preceding 27-day median TEC, storm time European region (with longitudes 30°W–50°E and latitudes 32.5°N–70°N). The (referred as TEC), latitude, longitude, universal ...

in order to evaluate the effects of foliar application of methanol on some physiological characteristics of chickpea under drought stress, an experiment was conducted as a factorial based on completely randomized design with three replications in 2011 at the recearch center of plant for sciences in ferdowsi university of mashhad. the first factor was different levels of methanol including, 0 (c...
