Abstract

The experiment was conducted over three consecutive years (2015-16, 2016-17, and 2017-18) during the spring season at Agricultural Research Station, Kota (Rajasthan) to evaluate the impact of ethrel and Gibberellic acid (GA3) on the germination, growth, productivity, and economic aspects of sugarcane cultivar CoPk 05191 (Pratap Ganna 1). The experimental soil was classified as clay loam, with moderate organic carbon content (0.52%), medium availability of phosphorus (25.30 kg/ha), and high levels of available nitrogen (354 kg/ha) and potassium (320 kg/ha), and a pH of 8.19. The present investigation was laid out in randomized block design with three replications. Sugarcane sets was planted in March and harvested after a 12-month at maturity. The application of growth regulators such as ethrel and gibberellic acid significantly influenced various growth and yield parameters throughout different stages of the crop. Treatments involving the planting of two budded setts soaked overnight in ethrel solutions of 50 ppm and 100 ppm (T3, T4, T7, and T8) showed marked superiority over conventional planting (T1) and soaking in water (T2) in promoting germination. Specifically, soaking setts in 50 ppm and 100 ppm ethrel resulted in comparable enhancements, significantly improving germination rates by 38.64-39.41% within the first 10 days of planting, tiller production by 28.98-29.47%, plant height by 16.13-16.62%, dry matter accumulation by 19.73-20.31%, and milleable cane yield by 22.74%-24.46% compared to the control group, for sugarcane cv CoPk 05191 (Pratap Ganna 1)

Conclusion

The mean data of three years on growth and yield of cane indicted that, germination, tillers, plant height and dry matter accumulation recorded at different stages under overnight soaking in 100 ppm ethrel solution was significantly superior to conventional and overnight soaking in water. Planting of two budded setts after overnightsoaking in ethrel solution (100 ppm) + spraying of GA3 (35 ppm) at 90,120 and 150 DAP exhibited significantly higher germination (38.64%), higher number of tillers (204.34 thousand ha-1), cane height (259.11cm), dry matter accumulation (340.57 g plant-1) and millable cane yield (98.88 t/ha-1) as compared to conventional planting
