GROWTH AND YIELD OF CARROT AS INFLUENCED BY POTASSIUM AND PLANT PER HILL

Abstract

The experiment was carried out to study the effect of different levels of potassium and number of plant per hill on growth and yield of carrot at the Horticultural Farm, Shcr- e-Bangla Agricultural University, Dhaka during the period of November 2006 to March 2007. The experiment consisted of two factors. Factor A- four levels of potassium viz. K () = Control, K| = 180 Kg, K 2 = 200 Kg, K^ = 220 Kg K 2 0/ha respectively. Factor B- Number of plant per hill viz P| = 1 plant per hill, P 2 = 2 plants per hill, = 3 plants per hill. The experiment was laid out with randomized complete block design (RCBD). Incasc of potassium highest yield (25.23 t/ha) was obtained from K and lowest (18.25 t/ha) from k 0 2 . Incase of number of plant per hill the highest yield (22.32 t/ha) was found from P* and lowest (19.27 t/ha) from P|. For combined effect of K 2 P? produced the highest (26.24 t/ha) yield and the lowest yield (13.81 t/ha) obtained from K 0 P| Considering the above findings, application of 200 kg k 2 0/ha with three plants per hill appeared to be suitable for cultivation of carrot.
