Effect of different Sources and Rates of Organic Fertilization on Sugar Beet (Beta vulgaris var. Saccharifera L.) Yields and its Quality Grown under Newly Reclaimed Sandy Soils

Abstract

At Kalabsho Experimental Farm, Dakahlia Governorate, Sugar Crops Research Institute, Agricultural Research Center, two experiments were done in the field throughout seasons of 2016/2017 and 2017/2018 to decide the effect of sources of organic fertilizers (farmyard manure FYM, compost CO and poultry manure PM) and its rates ( 0, 3, 5 and 7 t fed-1) on yields and its components and quality of sugar beet cv. Plino under newly reclaimed sandy soil conditions. A strip-plot design with 3 replications was used in these experiments. The obtained results showed that organic fertilizing of sugar beet plots with PM induced a gradual increment and produced in the utmost values of all studied yields and its components and quality parameters as contrasted with supplementary treatments within the two growing seasons. Application the utmost rate of organic fertilizers (7 t fed-1) formed the utmost values of yield and yield components and N, P and K contents in roots and foliage in mutually seasons. Although, the utmost values of sucrose and quality percentages resulted from using the organic fertilizers at 3 t fed-1 and the utmost values of sodium percentage were resulted as of control treatment in mutually seasons. Thus, it is suggested that fertilizing sugar beet fields with poultry manure (PM) at 7 t fed-1 would get the most out of sugar beet over the environmental circumstances of newly reclaimed sandy soils in Kalabsho distract, Dakahlia Governorate, Egypt.
