Effect of sucrosin bio stimulant on early growth of sugarcane (Saccharum officinarum L.) var. CM 2012

A study was carried out to study the effect of sucrosin bio stimulant application on the early growth of sugarcane (Saccharum officinarum L.) var. CM 2012 at the PT Perkebunan Nusantara XIV Arasoe Sugar Factory, Bone Regency, South Sulawesi from June to September 2019. The sucrosin was applied by immersing three segments of sugarcane cuttings (three eyes) for 30 minutes, then planted in a separate block from control treatment, with an area of 3 ha, respectively. Plant sampling was carried out diagonally on 10 rows of plants with a line length of 10 m per row. Data analysis was carried out using t test at α=0.05 level, correlation, and regression analysis to compare the growth parameters of sugarcane shoots, and to determine the relationship between shoot growth and the sucrosin treatments. The results show that the application of sucrosin to sugarcane cuttings significantly increased the early growth of sugarcane indicated by increase in shoot height, shoot and tillers number, and the number of leaf chlorophyll. The variable value of sucrosin treatment was highly correlated with the control indicated by the highest correlation value in the leaf chlorophyll number (0.996) and the lowest in the shoot height increase (0.991). The increase of the sucrosin treatment value in the regression equation is greater than the control, means, for each addition of one control value, the value of sucrosin treatment increased by 4.39, 10.70, 8.11 and 1.99 in the parameters of shoot height, number of primary shoots, number of tillers, and leaf chlorophyll number of sugarcane, respectively.
