Roles of Biostimulant (Agrispon) on Sugarcane (PC) at the Heavy Clay Soils “Vertisols”, Kenana Sugar Company, Sudan (Published)
A field experiment was conducted over two consecutive plant-cane seasons (2017/2018 and 2018/2019) at the Research and Development Farm of Kenana Sugar Company, Sudan, to evaluate the influence of the biostimulant (Agrispon) applied at five dose rates (0.00, 0.50, 1.00, 1.50, and 2.00 L/hec) on growth, yield, and quality parameters of sugarcane variety CO 6806. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications. Results demonstrated highly significant effects of bio-stimulant (Agrispon) on morphological and yield traits. Stalk height, stalk diameter, and internode number increased progressively with dose escalation, reaching maxima of 354.00 cm, 2.52 cm, and 26.50 internodes, respectively, at 2.00 L/ha. Similarly, stalk population (126.32 × 10³ stalks/hec), cane yield (127.15 TC/hec), and sugar yield (19.28 TS/hec) were maximized at the highest dose, representing improvements of 15.6%, 20.5%, and 18.6% over the control, respectively. In contrast, juice quality parameters include (Brix%, Pol%, fibre content, extractable reducing sugar content (ERSc), purity, and moisture) were unaffected by Agrispon treatments, suggesting that the biostimulant enhanced biomass accumulation without altering sucrose metabolism. These findings advocate the integration of Agrispon at 2.00 L/hec into sugarcane production systems on Vertisols as a sustainable yield-enhancement strategy.
