Abstract

This research was carried out in a private organic farm in 10th of Ramadan Association, Ismailia Governorate, and Laboratory of the Horticulture Department, Faculty of Agriculture, Suez Canal University during two successive seasons of 2019-2020 and 2020-2021, to investigate the effects of organic farming systems on the growth, yield and the biochemical attributes, such as sugars, phenolic and betalains, macro-elements content of leaves and roots (N, P and K) and micro-elements content of roots (iron, copper, zinc, manganese) of table beet plants (Beta vulgaris L.) “cv. Detroit dark red”. The experiment included four treatments, which were 100 % of the recommended fertilization dose (RFD) in the form of organic manure (poultry manure), 75 % RFD as organic manure (poultry manure) + 25% NPK, 50 % of the fertilization recommended dose as organic manure (poultry manure) + 50% NPK)and 100 % of the fertilization recommended dose in the form of chemical fertilizers organic manure (100% NPK) . The results showed that 75% organic farming system gave the highest values of the vegetative growth attributes, roots yield, sugars, betalains, phosphorus, potassium and micro-elements, under sandy soil conditions.
