Salient features
The technique has been developed for declining apple orchards and consists of:
• Severe pruning in February followed by application of Chaubattia paste on the cut surface.
• Caustic soda (1%) is sprayed during dormancy for management of lichens.
• Trees are supplied with 450 g N : 450 g P₂O₅ : 450 g K₂O/tree before fall.
• Need-based plant-protection measures should be followed during growth and fruiting.
Performance
• This way, the number of dead/infected twigs per tree reduced, and fruit set, number of fruits harvested/tree, fruit yield/tree improved.
Impact and benefits
• Technology is helpful in rejuvenating old, unproductive apple orchards, improving yield potential.
