Effect of bread yeast and mammoth on growth and yield of cabbage (Brassica oleraceae L.)‎

الملخص EN

This study was carried out at the vegetative research farm of the Faculty of Agriculture, University of Duhok, on cabbage plants during 2014-2015 season, to study the effect of three concentrations of bread yeast (0, 4,8 g.l-1), three concentrations of mammoth (0, 1, 2 ml.l-1) and their interaction on cabbage (Gunma F1).

The results showed that spraying with bread yeast significantly increased in leaves number, leaf area, stem length, dray weight, fiber, carbohydrate and total yield.

Mammoth led to positive significant differences in leaves number, leaf length with petiole, leaf area, stem length, root length, protein, vitamin C, total sugar, carbohydrate and total yield as compared to untreated plants.

The interaction between bread yeast and mammoth significantly enhanced all detected traits, since cabbage plants received 4g.l-1bread yeast and sprayed with 2 ml.l-1 of mammoth were characterized by the highest values of leaves number, leaf breadth, leaf area, stem length, vitamin C, TSS and total yield.
