A field study was carried out for two consecutive years (2022–23 and 2023–24) at the Horticultural Research Station, Mondouri, BCKV, to assess the influence of nano NPK on yield attributes, soil fertility, and leaf nutrient status of turmeric cv. Suguna under the agro-climatic conditions of West Bengal. The experiment was arranged in randomized block design with three replications and eight treatments. Different levels of conventional NPK fertilizers were integrated with foliar sprays of 0.4% nano NPK at 45 and 90 days after planting based on treatment combinations. Among the treatments T8 [40% N+75% P (Basal) → 0.4% nano NPK at 45 DAP→ 0.4% nano NK at 90 DAP] recorded the maximum weight of primary fingers (270.50 g), breath of secondary fingers (2.03 cm), weight, length and breadth of clump (394.44 g, 23.59 cm and 16.50 cm respectively), available soil nitrogen (241.84 kg ha-1), leaf nitrogen (1.74%), phosphorus (0.42%) and potassium (3.19%) content. The treatment also recorded maximum projected yield (34.95 t ha-1) in contrast the plants solely grown under conventional fertilizer (T1:40% N+100% P as basal→ 30% N+50% K at 45 and 90 DAP) recorded minimum yield (24.31 t ha-1), soil and leaf nutrient contains. The study indicated that combining nano fertilizers with conventional fertilizers improved yield traits while sustaining soil fertility in turmeric cultivation.
