K2O LEVELS ON GROWTH AND YIELD OF CARROT (Daucus carota L.)

An experiment was carried out in the Department of Horticulture, Sher-e-Bangla Agricultural University, Dhaka, during October 2006 to March 2007, to evaluate the influence of K₂O on growth and yield of carrot. The study consisted of four levels of mulch, viz., K₀, 0 Kg K₂O (control); K₁, 180 Kg K₂O per ha; K₂, 200 Kg K₂O per ha and K₃, 220 Kg K₂O. The experiment was done with randomized complete block design (RCBD) with three replications. However, all of growth and yield related traits showed the significant variation.  Therefore, highest (36.2 t/ha) marketable yield was obtained from K₂, while the lowest (30.0 t/ha) marketable yield was recorded from K₀. In case of economic analysis, cost benefit ratio showed that maximum (2.1) cost benefit ratio was in K₂ and minimum (1.7) found in control (K₀) for economic yield of carrot production.
