Response of pre-harvest plant bio-regulator applications over the bunch characters and yield traits in banana cv. Poovan under the Cauvery delta

Bananas are one the most important fruit crop which are the major economic source for several fruit growers. Lack of knowledge over the pre-harvest practices and insufficient post-shooting spray could be the contributing factors towards lower productivity in banana. Meanwhile, the inevitable use of plant bio-regulators has become a crucial component of the current cropping system with a view to improving the production of high-quality fruit. Hence, an investigation entitled ‘Effect of pre-harvest sprays with plant bio-regulator on bunch character and yield of banana cv. Poovan’ was taken up to access the impact of certain plant bio-regulators sprays over the bunch development and yield-related traits in banana cv. Poovan. The experiment was laid out in Randomized Block Design (RBD) with six treatments (T1 – GA3 50ppm, T2 – CPPU 2ppm, T3 – 2,4-D 25 ppm, T4 – Brassinosteroid 1 ppm, T5 – Sea weed extract 0.1% and T6 – control) and four replications. Two Bunch spray of treatments were given at the time of opening of last hand and at 20 days later the first spray. The results revealed that the bunch treatment with GA3 at 50 ppm recorded highest yield and found effectiveness over the bunch characters and yield of banana.
