| Abstract | ||
| This investigation was carried out at Shandweel Research Station. Sohag Governorate in the two successive seasons of 1997/1998 and 1998/1999 to evaluate the effect of nitrogen (150.190 and 230 kg N/ fed) and potassium (48 and 96 kg K20/fed) on yield and quality of two sugar cane promising varieties (G. 85/37 and G. 84/47). The results showed that sugar cane variety G.85-37 attained a superiority in plant height, cane and sugar yields over G. 84-47 variety. Increasing nitrogen level up to 230 kg N/fed increased stalk height, stalk diameter, cane and sugar yields of sugar cane varieties compared with the lowest dose (150 kg N/fed). Juice purity and sugar recovery percentages were adversely affected by increasing the applied N-level. Applying potassium fertilizer had no significant effect on stalk height, stalk diameter, purity and sugar recovery percentages. The results showed that increasing potassium level from 48 to 96 K20 significantly affected cane and sugar yields in the 1st season. | ||
