EFFECT OF DRY YEAST AND LICORICE SPRAY ON GROWTH AND YIELD OF LOCAL CULTIVAR MUNG BEAN

Abstract

A field experiment was conducted during spring season of 2016 in Al- Zidan district,Abu-Graib,Baghdad to study the effect of spraying three concentrations of dry yeast (0,5 and 10 g.L-1) and three concentrations of licorice (0, 5 and 10 g.L- 1) on the growth and yield of the local cultivar of mung bean (Vigna radiate). A factorial experiment was done according to R.B.C.D with three replicates. The first factor was the concentrations of the dry yeast and the second was the three concentrations of licorice extract. The results show High concentrations of yeast and licorice extracts were superior for most studied traits, since 10 g.L-1of yeast extract achieved the highest mean ofplant height, number ofbranches, pod length, number ofpods (32.2 pods plant-1) number of seeds perpod (9.4 seeds pod-1) and seed yield (1078,9 kg ha-1) the highest concentration of licorice extract achieved highest number of branches, leaf area, pod length, number of pods (30.7 pods plant-1), number of seeds perpod (8.7 seeds pod-1) and seed yield (1076,7 kg ha-1). Interaction between yeast and licorice extracts concentrations significantly affected most studied traits. Plants sprayed with the highest concentrations of yeast and licorice showed the highest mean of leaf area, number of pods per plant, number of seeds per pod, pod length and seed yield for unit area while plants of control recorded lowest means of aforementioned traits.
