Item GROWTH AND YIELD OF CARROT AS INFLUENCED BY MULCHING AND POTASSIUM(DEPT. OF HORTICULTURE, 2008) FERDOUSI, FATIMAThe experiment was conducted in the Farm of Sher-e-Bangla Agricultural University, Dhaka, during October 2006 to march 2007 to find out the eulèct of mulching and potassium on growth and yield of carrot. The experiment consisted of two factors. Factor A: Four levels of mulch viz. M 0 : Control, M 1 : Black polythene, M2 : Water hyacinth and M 6 : Saw dust; Factor B: Four levels of potassium viz. K Control, K1: 180 kg K 2 0/ ha, K 2: 200 kg K 20/ ha and K 3: 220 kg K 2 0/ ha. The experiment was laid out with randomized complete block design (RCBD) with three replications. In case of mulching, plant height and fresh weight of root is significant for growth stage. The highest (36.35 t/ha) marketable yield was obtained from M 1 , while the minimum (31.57 t/ha) marketable yield was recorded from M 0 . In case of potassium, plant height and dry matter content of roots is significant for growth stage, K 2 produced the highest (36.20 t/ha) marketable yield of carrot while control plots produced the lowest (30.05 t/ha). For combined effect, plant height, length of root, diameter of root and fresh weight of root is significant for growth stage and M1K.2 produced the highest marketable yield (38.93 t/ha). while M 0K0 gave the lowest (25.14 t/ha). So, black polythene mulch with application of 200 kg K 2O/ha is suitable for better growth and yield of carrot
