GROWTH AND YIELD RESPONSE OF CARROT (Daucus carota L.) TO PHOSPHORUS

The experiment was conducted at Horticultural Farm, Sher-e-Bangla Agricultural University, Bangladesh during the period from November 2008 to February 2009 to study the effect of phosphorus on growth and yield of carrot. Four levels of phosphorus viz., P₀: 0 kg P₂O₅/ha (control), P₁: 50 kg P₂O₅/ha, P₂­: 60 kg P₂O₅/ha and P₃: 70 kg P₂O₅/ha using Randomized Complete Block Design with three replications. Most of the characters including yield/ha showed higher results for P₃. The highest marketable yield (35.9 tha^-1) was recorded from P₃ whereas lowest (24.1 tha^-1) from P₀. It can be suggested to use 70 kg P₂O₅ per hectare for higher production of carrot.
