Response of Williams banana plants to application of EM and yeast [electronic resource].

Includes reference.

This study was conducted at a privet orchared located in AIwasta district, Assiut Governorate during 2005 / 2006 and 2006 / 2007 growing seasons to evaluate the effects of soil application of active dry yeast at (15 ,30 and 60 g /plant / year ) and EM, a commercial biostimulant at (150 ,300 and 600 ml /plant / year) as well as a combined of 60 g dry yeast and 600 ml of EM / plant /year on the height and girth of pseudostem, total leaf area of the plant , leaf N P K, bunch weight, weight of hand and finger, number of hands per bunch, pulp/peel as well as percentages of starch, total soluable solids, total and reducing sugars of Williams banana. fruit .The soil applicaation was added at three equal doses (end of May ,June and July). Results indicated that supplying Williams banana plant with active dry yeast and EM biostimulant either alone or in combination was responsible for enhancing growth aspects ,nutritional status of plants , yield as well as physical and chemical characters of the fruits compared to untreated plants .Using 60 grn /plant !year of active dry yeast considerably increased all the studied prameters compared to the other dry yeast applications, also this increment was observed with using 600 ml EM biostimulant compared to the other EM treatments . The best results with regard to pseudstem length and girth, leaf area, bunch and hand weights, number of Ilands per bunch fruit physical and chemical properties as well as leaf N , P and K % were detected due to using a mixture of 60 g /plant / year active dry yeast and 600 ml / plant / year EM biostirnulant divided to equal three doses at the end of May ,June and July.
