Effect of Different Levels of Nitrogen (N) And Phosphorus (P) Fertilizer on Growth and Yield of Lettuce in Coastal Zone of Bangladesh

The experiment was conducted at the Agriculture Field laboratory of Noakhali Science and Technology University, Noakhali, Bangladesh during period from December 2020 to February 2021 observe effect different levels nitrogen (N) phosphorus (P) fertilizer on growth yield lettuce. comprised two factors. Two inorganic fertilizers like level viz; nitrogen-control 0 kgha-1 (N0), 100 (Nı), 150 (N2) 200 (N3) phosphorus-control (P0), 50 (P1), 62.5 (P2) 75 (P3). laid out in Randomized Complete Block Design (RCBD) with three replications. Application significantly influenced plant height, leaves number plant-1, leaf area, fresh gross yield, dry matter content maximum were obtained application kg N ha-1. On other hand, P ha-1 found. In case treatment interaction, N3P3 (200 + ha-1) produced highest (32.2 tha-1) lowest (16.11 found control treatment.
