Efficiency of selection and bacterial inoculation in the growth vegetative traits of mungbean

الملخص EN

Field experiments were carried out at the research station, college of Agricultural Engineering Sciences – University of Baghdad, the aim of this study is trying to improve some mungbean genotypes and study the effect of bio fertilizer on them.

Experiment was designed as randomized complete block design RCBD in split plots arrangement with three replications, treatments fertilizers occupied main plots.

Whereas genotype occupied the sub plots.

The results showed that the selected Argentine genotype was superior in most studied traits despite its little response to selection due to the homogeneity of its plants.

The treatment of bio fertilizer with recommendation 75% N showed significantly increased in all vegetative traits, as plant height (89.63 cm), leaf area (621.1 cm2 plant-1), leaf area index (15.58), weight of dry matter (109.3 g), crop growth rate (19.25 g m-2 day -1), yield per plant (52.12 g), followed by treatment bio fertilizer with recommendation 50% N.

It can be concluded, that selection was efficiency for local variety and the combination of bio fertilizer and chemical fertilizer gave the best vegetative traits in mungbean.
