The experiments were conducted in the Instructional farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal in two successive Rabi seasons of 2005-06 and 2006-07with an objective to study the incidence of saw fly (Athalia lugens proxima Klug.) as influenced by level of irrigation and fertilizers on mustard c.v. NC-1 (Jhumka) of Brassica campestris var. yellow sarson. Highest saw fly population (0.26 larvae/plant) was recorded on the crop grown without irrigation and medium level of fertilizers (60:30:30 Kg NPK ha-1) while lowest population level (0.10 larvae/plant) was observed at highest level of irrigation (three) coupled with medium level of fertilizers (60:30:30 kg NPK ha-1) and two irrigations coupled with lowest level of fertilizers (40:20:20 Kg NPK ha-1).
