Abstract:
A field experiment employing six elite sugarcane varieties, namely CoP 16437, CoP 112, BO 153, CoP 2061, BO 154 and CoP 9437 along with two different irrigation regimes (IW: CPE ratio 1.0 and 0.3) was conducted during spring season of 2018-19 at Sugarcane Research Institute, RPCAU, Pusa, Bihar to evaluate growth, yield and quality of sugarcane varieties as well as economics under drought condition. The experiment was laid out in strip plot design with three replications having twelve plots in each replication. In this paper, we discussed about only growth parameters. The data revealed that CoP 2061 performed well in terms of highest plant population (87.5× 10³ /ha and 130.8× 10³ /ha) at 60 and 90 DAP, plant height (130.0 cm and 196.0 cm) at 150 and 180 DAP, LAI (0.54, 1.81 and 2.99) at 50, 100 and 150 DAP, respectively. Application of irrigation regimes, IW: CPE ratio 1 showed significantly higher plant growth attributes compared to IW: CPE ratio 0.3 at all growth stages.
