Effect of yeast and micronutrients foliar application on leaves and racemes growth, yield and fruit quality of loquat (eriobotrya japonica lindl.) treeslh[electronic resource].

Includes references.

To improve the growth, yield and fruit quality of loquat, an experiment was conducted on "Advance" loquat trees grown at Tawfikia village, Damietta Governorate, Egypt, during 1999 and 2000 years. Solutions of active yeast at 1.25 or 2.5 g/l and micronutrients mixture (Fe, Mn and Zn sulphate, 250 ppm of each) either alone or in combinations were foliar applied at both full-bloom (Fb) and after 7 weeks from Fb. The most tested treatments significantly increased leaf area, raceme length, fruit number/cluster at harvesting, leaf chlorophyll (b and total) and yield/tree compared with the control. Application of yeast at 2.5 g/l alone or with micronutrients significantly surpassed yeast at 1.25 gil and micronutrients alone in that respect. Key words: loquat, yeast foliar application, leaf cWorophylls content, leaf micronutrients and phosphorus, growth, yield, fruit quality, total reducing sugars, fruit proteins content
