Abstract

Proper nutrition is essential for satisfactory crop growth and production. A field experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, to evaluate yield and quality of Grand Rapids lettuce using various levels of phosphorus and boron. Treatment combination of 120 kg ha-1 of phosphorus and 2 kg ha-1 of boron has significantly increased plant height, leaf number, leaf length, plant canopy, capsules plant-1, seeds capsule-1, seeds number plant-1, seed yield ha-1, germination (%), planting value (%), moisture (%), purity (%), dry matter (%) and 1000 seed weight. Most of the treatment combinations performed better than control treatments in all parameter. The finding could be helpful to determine the precise levels of phosphorus and boron to improve the yield and quality of lettuce.
