Crop raiding has been reported in many parts of Punjab as a result of an overabundance of nilgai antelopes (Boselaphus tragocamelus) and farmers are constantly battling to save their crops. In the present study, various management strategies such as physical deterrents (nylon rope, nylon net and garden net), visual repellents (scarecrow and reflective ribbon), chemical repellents (different concentrations of Neelbo and Ecodon (based on ricinoleic acid) applied by spraying, soaking jute rope, soaked in wood shavings packed in plastic bags and paper cups) and biological deterrents (bioacoustic device and different concentrations of faecal solution of horse, tiger and Himalayan black bear) were evaluated to minimize the damage caused by nilgai. Nylon net was the most promising method, providing complete protection against nilgai, which can be used for protecting crops at vulnerable stages with a one-time cost. The nylon rope and garden net provided partial protection from nilgai damage. The bioacoustic device and reflective ribbon were also effective for a short period of time. Neelbo was found more effective as chemical repellent against nilgai. The faecal solution of horse and Himalayan black bear remained effective as repellent for 10 days. It is thus concluded that while comprehensive damage prevention may be difficult, animal management devices can help reduce nilgai damage at vulnerable stages of the crop. The employment of a range of management devices at the proper time can be part of a cost-effective system to keep nilgai damage at acceptable levels.
