Studying the growth characters, yield and elements concentration of chickpea (Cicer arietinum) affected by different manure combination

In order to study the effect of biological manure on efficiency of some manure mixtures and select the best manure combination to reach highest chickpea yield, an experiment arranged in randomized complete blocks design with three replications in Field Research of Payam Noor University of Arak. Treatments were different manure mixtures include: 1- No manure (Control), 2- Animal manure, 3- Vermi-compost, 4- Animal manure+ phosphorus and potassium powder, 5- Vermicompost+ phosphor and potassium powder,6- Animal manure+ phosphor and potassium powder+ biological manure include Iron and phosphate biological manure and rhizobium, 7- Vermicompost+ phosphor and potassium powder+ biological manure. Tested characters were plant height, number of primary and secondary branches, total biomass, 100 seed weight, seed yield, and content of N, K, Ca, Mn and Fe in plant. The results showed the effect of manure type was significant on all of the tested traits. The highest seed yield and growth criteria were obtained from two triple manure mixtures. In Animal manure+ phosphor and potassium powder+ biological manure and Vermicompost+ phosphor and potassium powder+ biological manure, use of biological manure by increasing plant necessary elements, respectively, caused to 6 and 7 percent increases in seed yield compare to without biological manure treats and 32 and 33 compare with control. On the basis of result, using biological manure caused to improve elements absorb, growth and seed yield of chickpea.
