Abstract
Basem Mohamed Mohamed Bakr: Effect of Some Organic and Biofertilizers on Productivity and Fruit Quality of Balady Mandarin Trees. Unpublished M.Sc. Thesis, Department of Horticulture, Faculty of Agriculture, Ain Shams University, 2009.
This trial was carried out during the two successive seasons (2005 and 2006) on 25 years old Egyptian Mandarin trees budded on sour orange rootstock grown in loamy soil which were fertilized with nitrogen at 1000 g/tree in different organic sources (cattle, chicken and compost) alone or enriched with biofertilizer application. Fruit set %, fruit DROP %, yield / tree, fruit quality and leaf mineral content were determined in both seasons. The obtained results showed that fertilizing trees with mineral and organic N sources accompanied with biofertilizer or organic source as chicken or cattle manure at 75 % with biofertilizer as well as 100 % without biofertilizer significantly increased fruit set, yield as number of fruits and weight Kg/ tree , fruit quality and leaf mineral content. So, it seems that yield and fruit quality of Egyptian Mandarin trees could be improved by fertilizing with 75% mineral N (3.6kg ammonium sulfate) + 25% organic N (14.5 kg cattel manure) + 0.5 kg biofertilizer as micropen under the conditions of El-Kalubia Governorate.
