Eid El-Gizawy, Gamal Shalaby and Esawy Mahmoud( 2013). Effects Of Tea Plant Compost And Mineral Nitrogen Levels On Yield And Quality Of Sugar Beet CropCommunications in Soil Science and Plant Analysis - Decision on Manuscript ID LCSS-2012-0537.R1(in press).
Abstract: A field experiment was carried out during two successive seasons of 2009/2010 and 2010/2011 at Sakha Agriculture Reseach Station, Egypt to study the effects of different application of compost tea (C) under three mineral nitrogen (N) levels and their interaction on sugar yield and juice quality characteristics of sugar beet (Beta vulgaris L.), and soil available nutrients. Results indicated that, the sugar yield and juice quality characteristics of sugar beet were significantly increased with compost tea treatments, especially in the plots treated with compost tea foliar application at thrice batches. A quality percentage of sugar beet was increased about 8.0% in the plots treated with compost tea or interaction between N –mineral and compost tea treatments above control treatment. The interaction between N –mineral and compost tea treatments had a significant effect on sugar yield, sugar percentage, purity and quality of sugar beet and soil fertility.
