Sugarcane, Saccharum spp. L., is an important commercial crop for its white crystal sugar and biofuel. High production of sugarcane depends on planting high-yielding variety and quality seed cane. Therefore, a field experiment was conducted with the objectives of evaluating the effect of the time gap between seed cane cutting to the planting of sugarcane varieties on growth parameters and yield of sugarcane during the 2018–2019 cropping season at Finca'a Sugar Estate, Ethiopia. The treatments consisted of eight durations of time gap between seed cane cutting to planting (fresh (0), 24, 48, 72, 96, 120, 144, and 168 h stale seed cane) and two sugarcane varieties, namely N14 and D42/58 using randomized complete block design (RCBD) in a factorial arrangement with three replications. The time gap between seed cane cutting to planting significantly (P ≤ 0.05) affects sprout %, number of tillers, and number of millable cane. However, cane height and weight, and node length had significantly (P ≤ 0.05) influenced by sugarcane variety. The main factors and their interaction had a non-significant effect on cane girth, the number of nodes, leaf area index, and specific leaf weight. The maximum value of seed cane and sugar yield was recorded from fresh seed cane. The higher value of sprout % (75.5), tiller population (10.09 × 104 /ha), and the number of millable cane (14.88 × 104 /ha) recorded from seed cane stale for 24 h before planting. Planting N14 sugarcane variety resulted in significantly higher internode length (12.32 cm), stalk height (206 cm), cane weight (1.49 kg), cane yield (1.84 × 102 t/ha), and sugar yield (20.921 t/ha). Planting seed cane which did not stale more than 24 h was more beneficial to get the high number of sprout, tiller count and the high number of millable cane, cane yield and sugar yield. N14 was recorded high yielder than D42/58 sugarcane variety. Planting seed cane of N14 sugarcane variety which could not stale (time gap between seed cane cutting to planting) more than 24 h is recommended to get high yield in the area. [ABSTRACT FROM AUTHOR] |
