Irrigation water was calculated based on the ratio of irrigation water (IW) to cumulative pan evaporation (CPE) measured with USWB Class-A Open pan. The six treatments were: I_0 (no irrigation /control), I_1 (only one irrigation in the first week of plantation), I_2 (I_1 + late irrigation at IW:CPE = 0.25), I_3 (I_1 + late irrigation at IW:CPE = 0.50), I_4 (I_1 + late irrigation at IW:CPE = 0.75), and I_5 (I_1 + late irrigation at IW:CPE = 1.00). The germination rate of sugarcane eye buds in the irrigated plots was significantly higher than that in the non-irrigated/controlled plots. At 60 days after planting (DAP), I_3, I_4, and I_5 receiving 2 irrigation amounting 20 cm recorded significantly (P\u003c0.01) the 28- 34% higher germination rate over the plots receiving only one irrigation/no irrigation. Treatment I_4 resulted in the highest germination rate (56.6%) and I_0 resulted in the lowest rate (37.91%). Treatment I_5 produced significantly (P\u003c0.01) large number of tillers (212.58x10^3 ha^\u003c-1\u003e) following I_4 and I_3 which was 10.9- 42.0% higher over I_0 (149.29x10^3 ha^\u003c-1\u003e). The highest millable cane (124.46x10^3 ha^\u003c-1\u003e) was obtained from I_4 following I_3 and I_5 but the millable canes of these treatments were statistically identical and were significantly (P\u003c0.05) higher (41.9%) over I_0 (72.22x10^3 ha^\u003c-1\u003e). Tiller mortality was higher (51.80%) in the control (I_0) than that in the irrigated canes (36.6-40%). However, irrigation did not significantly influence the sucrose content of the cane. There was a favorable influence of irrigation on the cane yield. The highest cane yield (114.42 t ha^\u003c-1\u003e), which is 40% higher than that with no irrigation (72.22t ha^\u003c-1\u003e) was produced by I_4 receiving 60-cm irrigation water. I_4 also produced significantly large quantity of sugar (12.32 t ha^\u003c-1\u003e), which was 42.6 % higher than that of the I_0 (7.07 t ha^\u003c-1\u003e). The total water used by the sugarcane increased linearly as the irrigation frequency increased. However, cane yield did not increase linearly with increasing water use. The highest WUE (0.70 t ha^\u003c-1\u003ecm^\u003c-1\u003e) was obtained from the irrigation treatment I_3 and the lowest (0.47 t ha^\u003c-1\u003ecm^\u003c-1\u003e) was obtained in I_0. Premonsoon irrigation of sugarcane with 48.5 cm water at IW:CPE ratio of 0.6 resulted in the highest cane yield (110.42 t ha^\u003c-1\u003e) and sugar production (11.82 t ha^\u003c-1\u003e) with WUE of 0.70 t ha^\u003c-1\u003ecm^\u003c-1\u003e and total crop water use of 157.74 cm.", "subitem_description_type": "Other"}, {"subitem_description":
