“…in both seasons, while the lowest one recorded for 20 kg K 2 O, these results may be due to the beneficial influence of increasing level of potassium on the growth of sugarcane plants in respect to millable cane length, number of millable cane m 2 and diameter of millable cane Table (1, 2 and 3), which reflected on cane yield /fed. These results are in accordance with those obtained by Taha et al, (2003) El Tilibet al, (2004), and Abd El-Kader (2017. The interaction effect between the two studied factors was significant in the two seasons.…”

“…The positive effect of the highest potassium level may be due the most important element for sugar cane. Taha et al, (2003) reported similar results.Also, data revealed that the interaction effect of the two studied factors was significant in the second season. The highest values of this trait obtained by 22 irrigations with 60 kg K 2 O/fed., while the lowest ones produced by 16 irrigations treatment with 20 kg k 2 o/fed.…”

“…Juice quality parameters and sugar yield were increased with the application of 50 and 75 kg K 2 0/fed., respectively. Taha et al(2003) found that potassium application significantly increased stalk diameter ,millable cane yield and sugar yield / fed. In general, all traits were increased by increasing K levels application compared to the control.…”

A field experiment was carried out at private farm in Aswan Governorate, Egypt during 2013/ 2014 and 2014/2015 seasons to study the effect of number of irrigations, potassium fertilizer levels and their interaction on sugarcane. The experiment included fifteen treatments represent three irrigation (22, 19 and 16 irrigations) and five potassium levels (20, 30, 40, 50 and 60 kg K 2 O/fed.). A spiltplot design with four replications was used in both seasons. Irrigation treatments were allocated in the main plots, while potassium fertilizer levels were randomly distributed in the subplots. The experimental unit area was 21 m 2 with 6 ridges of 3.5 meters in length and 1.0 meter apart. The commercial cane variety of G.T.54/9 was planted during the first week of March using dry method in both seasons.The results revealed millabel cane length, number of millable cane /m 2 , diameter of millable cane, millable cane yield(ton/fed.), sugar yield (ton/fed.), total soluble solids, sucrose percentage and sugar recovery percentage were significantly affected by irrigation treatments in both seasons. Twenty-two irrigation produced the highest values for the previous traits. It was found that potassium level of 60 kg K 2 O /fed.significantly increased these characters in the two seasons. The interaction effect between irrigation treatments and potassium levels was significant for all studied traits except no. of millable cane /m 2 in both seasons. Fertilized sugarcane with 60 kg K 2 O /fed. with 22 irrigations produced the highest valuesfor the previous traitsin the two seasons.The data revealed that irrigation treatments attained a significant effect on purity percentage and reducing sugar percentage in both seasons, the highest purity percentage resulted from 19 irrigations treatment in both seasons. On the other hand, -158 -the highest reducing sugar percentage resulted from16 irrigations treatment. Increasing potassium fertilizer level caused decrease in purity percentage and reducing sugar percentage in both seasons.In conclusion, cultivation of the commercial sugarcane variety G.T. 54/9 at Aswan Governorate with applying 22 irrigation during the growing seasons and fertilizing sugarcane plants with 60 kg K2O /fed. cleared positive response to improve yields of cane and sugar and maximized production of sugarcane crop.
