Effect of Different Levels of Potassium Sulphate Fertilizer on Growth, Yield and Quality of Sugarcane Ratoon one in Two Sites in Sudan

Abstract

Research have been conducted in two sites in Sugarcane Research Center Farm in Guneid-Sudan from January, 2019 to September, 2020 in two sites. The study aimed to evaluate the effect of potassium sulphate fertilizer doses on the growth of sugarcane ratoon one. The variety tested was Co 6806. The treatments consist of five doses of potassium sulphate (SOP) fertilizer which contains (50%K2O and 18%S); K1: 0.0, K2: 40, K3: 80, K4: 120 and K5: 160 kg SOP kg ha-1 arranged in randomized complete block design (RCBD) replicated three times. The results obtained that there was a significant effect on sugarcane ratoon one growth, yield and all quality parameters due to the application of different levels of potassium sulphate fertilizer in the two sites. Statistically, the treatment K3: (80 SOP kg ha-1) recorded significantly the highest cane and sugar growth, yield and quality values compared to the other potassium sulphate levels and the control in the two different experimental sites.
