EFFECT OF GROWING MEDIA ON GROWTH AND YIELD OF POTTED PAKCHOI

Abstract

An experiment was accomplished in the rooftop of Dr. M A Wazed Miah central laboratory of Sher-e-Bangla Agricultural University, Dhaka during the period from December 2020 to February 2021 to study on effect of different growing media on the growth and yield of potted Pakchoi. The experiment comprised of eight levels of different growing media viz., T – Control(100% soil), T 1 – Vermicompost (90%), T 2 ii

0 - Cocodust + Vermicompost (45%+45%), T 3 – Mushroom Spent Compost(90%), T – Vermicompost + Cowdung (45%+45%), T 5 4 – Vermicompost + Mushroom Spent Compost (45%+45%), T

– Vermicompost + Mushroom Spent Compost + Cowdung (30%+ 30%+ 30%) and T 7 – Vermicompost + Biochar (45%+45%). Treatment T was 100% soil and 10% soil were added in rest 7 treatment equally. This experiment arranged in Completely Randomized Design (CRD) with three replications. Data on different growth and yield attributes parameters were taken in which all the treatment showed significant variations. The tallest plant (24.50 cm), the maximum number of leaves (20), the maximum leaf length plant 0 (23.00 cm), the maximum leaf breadth (13.00 cm), the highest fresh weight with root (415.00), the maximum fresh weight without root (410.00 gm), the maximum root length (13.00 cm), the maximum shoot diameter (8.90 cm), the maximum stem diameter (1.10 cm), the maximum stem length (4 cm) were counted in T

(Vermicompost) treatment but the maximum dry weight (12.36 gm) and the maximum root weight (10.00 gm) were found from T (Mushroom Spent Compost) treatment. The highest yield of pakchoi (18.22 t ha 3 -1 ) was recorded from T 1 (Vermicompost) treatment. Significantly higher yield (18.22 t ha ) was recorded from T (Vermicompost) treatment while the lowest yield (1.67 t ha -1 1 ) was recorded from T (Vermicompost + Biochar) treatment. It was apparent from the above results that the treatment of T 7 was more suitable than rest of treatment. The total soluble solids (12.50 0 1 -1 Brix) was higher in T , maximum Vitamin-C (37.30 mg/100g) was recorded in T treatment and maximum moisture percentages (92.42%) were found in T treatment.
