Abstract:
The study was undertaken to demonstrate the management of Brown plant hopper (BPH), Nilaparvata lugens in rice with formation of Alleyways of 20 cm for every 2 metre, recommended dose of nitrogenous fertilizers (100 kg of N/ha), alternate wetting and drying, spraying of Azadiractin (1500 ppm)@ 5ml/l and Spraying of Buprofezin@1.6ml/l for control of brown plant hoppers. Results were compared with farmers practice plots, the BPH population was lower in the demonstrated plots with 5.6, 6.6 and 8.7 adults/ hill at 60 DAT and 13.4, 15.1 and 15.4 adults/hill at 75 DAT with increased yield of 13.2, 5.9 and 5.1 percent during Kharif 2018, Kharif 19 and Kharif 2020 respectively. The benefit cost ratio was higher 2.5:1, 2.67:1 and 1.96:1 in technology demonstrated plot and lower in farmers practice plots with 2.17:1, 2.43:1 and 1.73:1 during kharif 2018, kharif 2019 and kharif 2020 respectively.
