Abstract:
A field investigation was conducted at experimental field, Department of Horticulture, College of Agriculture, CAU, Imphal, during 2021-22 to study the “Influence of graded levels of inorganic with organics and biofertilizers on growth and yield of turmeric”. The experiment was laid out in RBD (Randomized Block Design) with three replications under 13 different treatments including recommended NPK 100%. Four organics (compost, vermicompost, mustard cake and neem cake), three biofertilizers (Azotobacter chroococcum, Bacillus polymyxa and Fraturia aurantea) and three levels (100%, 75% and 50%) of NPK were included in this experiment along with recommended dose of NPK (150:60:150 kg/ha). Maximum breadth of leaves (18.97 cm) was recorded at 120 days after planting from the treatment combination of Neem cake + NPK 100% + BF. Maximum number of leaves per clump (13.37) at 120 DAP was recorded in Vermicompost + NPK 75% + BF. Mustard cake + NPK 100% + BF recorded the maximum number of primary finger (7.60), clump length (18.76 cm) and clump breadth (13.97 cm). The maximum weight (161.33 g), length (9.22 cm) and breadth (2.43 cm) of primary finger were recorded from the treatment combination of Compost + NPK 100% + BF. The maximum plant height (142.87 cm), number of tillers per clump (2.32) and length of leaves (67.40 cm) at 120 days after planting were observed in Vermicompost + NPK 100% + BF. Similarly, maximum clump weight (327.52 g) and yield per hectare (38.50 t) were obtained from treatment combination of Vermicompost + NPK 100% + BF.
