| Abstract | ||||
| A field experiment was conducted on a calcareous soil at Noubaria region to identify response of sugar beet to fresh or composted farmyard manures (FFYM or CFYM) at rate 10 of ton/fed in combination with 40 kg N/fed added from different sources, i.e., urea, ammonium nitrate and diluted nitric acid. Plant samples were taken after 16 and 25 weeks from planting to define vegetative parameters (plant height, leaf numbers, root length and diameter). Shoots and roots were chemically analyzed to determine chlorophyll A, B, carotene, total soluble sugar and reducing sugar contents. Data obtained showed that applying organic manures (FFYM and CFYM) led to improve many of soil variables such as organic matter content, soil pH, soil salinity, CEC and available NPK, with superiority for CFYM. The combination of CFYM and ammonium nitrate exhibited the best results of vegetative growth parameters, yield, sugar concentration and its purity. Also, a positive correlation was found between sugar purity and potassium content in leaves. Reducing sugar content was more affected by the studied treatments as compared to the total soluble sugar content. | ||||
