Abstract:
Rice (Oryza sativa L.) is the most important cereal crops in the tropical and subtropical region of the world. Rice crop is affected by many fungal, bacterial, viral and nematode diseases. Among the fungal diseases the bakanae disease is an emerging disease of rice and cause severe losses. Bakanae disease causing pathogen produces different type symptoms on rice, such as; seedlings elongation, foot rot, seedling rot, chaffy grains and grain discoloration. Management of this disease includes chemicals, bio-agents and other cultural practices. Since chemical management has its own certain drawbacks like environmental pollution. There is a more scope to develop suitable package of cultural practices to manage the bakanae disease. Among cultural practices, one of the important practices is application of balanced fertilizer. Therefore, a study was undertaken to look at the effectiveness of nutrients on foot rot disease of PB- 1121 variety of basmati rice. In field condition, in respect of different doses of fertilizers, minimum 2.68% disease incidence was observed in recommended dose of NPK+ Z_nSo₄ + FeSO₄ + Carbendazim (0.1%) followed by double dose of K & recommended dose of N&P with 3.38% disease incidence. Maximum (9.12%) disease incidence was observed in double dose of Nitrogen and recommended dose of phosphorus and potash over the control (9.94%). So, it can be concluded that use of Carbendazim with recommended dose of balanced fertilizer may be useful for eco-friendly management of bakanae disease of rice.
