Abstract
Mustard (Brassica sp.) is one of the main oilseed crops of Rabi season in Punjab. Mustard covers an area of 60 thousand ha with yield of 62 thousand tons in Punjab. The present study was undertaken to analyse the avian diversity at different growth stages of the mustard crop and to evaluate the efficacy of integrated bird pest management. The study was carried out at two locations i.e. Punjab Agricultural University, Ludhiana and University Seed Farm (USF), Ladhowal in district Ludhiana during 2020-21 in Rabi season. A total of 40 species of birds were observed during the study at the selected locations (Punjab Agricultural University, Ludhiana and University Seed Farm, Ladhowal). Out of these, 36 bird species were found to be insectivorous and out of total bird species observed, 57% belongs to order Passeriformes. Damage assessment was done at sowing and ripening stage of the mustard crop at both the locations by using different management methods viz: bird protection Net, Jute Rope, CD and Reflective Ribbon. Percentage of germination of plants were more in net, then in jute rope, followed by CD further followed by reflective ribbon. It was found that number of damaged plants were less for experimental plot in comparison to control plot and the difference was statistically significant. Similarly, damage was assessed at ripening stage by counting the number of damaged pods and intact pods in the crop. Moreover, in case of pods, among all the experimental field installed with different management methods, damage was found to be less in net, followed by CD, further followed by reflective ribbon and jute rope. It was concluded that use of net was found to more effective among all other management methods used at sowing and ripening stages of the mustard crop.
