The effect of irrigation and nitrogenous and phosphorous biofertilizers on yield and yield component on chickpea (Cicerarietinum L.) ILC482 line

<p>To evaluate the effects of nitrogenous and phosphorous biofertilizers on yield and yield components of chickpea<br>under different irrigation levels a research was conducted in a split plot experiment with three replicationsbased<br>on completelyrandomized block design at Research Field of Islamic Azad University Tabriz Branch in the spring of<br>2009. Irrigation levels (normal and deficit irrigation) were considered as a main factor and also fertilizers levels<br>(control, nitragin, biosuper and nitragin + biosuper) sub factors respectively. Control treatment of biofertilizer<br>showed fewer enhancements. Comparison of biofertilzer treatments showed that nitrogen + biosuper biofertilizer<br>increased more number of pods with one seed per plant by 19/28, number of pods with two seed by 15/28, seed<br>weight per plant by 4/47 g/m2, pod weight per plant by 5/93 g/m2and yield by 89/39g/m2. There is no significant<br>difference among nitragen ,biosuper and control treatments.Comparison of the different irrigation levels effect on<br>number of pods with two seed per plant showed that complete irrigation produced more number of pods with two<br>seed per plant by 24/1.and 100 seed weight by 30/76 g nitragen and biosuper produced significant yield relative to<br>other treatments.
