EFFECT OF SPACING AND HARVESTING INTERVAL ON THE GROWTH AND YIELD OF INDIAN SPINACH

Abstract

Present experiment was conducted at the Horticulture Farm of the Sher-e-Bangla Agricultural University, Dhaka, during the period from March to July 2007. The experiment consisted with two factors. Factor A: Four plant spacing viz. S 1 : 50 cm x 30 cm, S2: 50 cm x 40 cm, S3 : 50 cm x 50 cm and S 4 : 50 cm x 60 cm and factor B: Three harvesting intervals viz. H 1 : 10 days, 1 -12: 15 days and H3: 20 days. In case of plant spacing, the longest plant (34.48 cm), maximum number of branches (6.25) and the highest yield (22.69t/ha) was recorded from S 3 while all the above parameter was lowest at S 1 . For harvesting intervals, the longest plant at harvest (41.63 cm), maximum number of branches per plant (6.01) and the highest yield (21.57 t/ha) was recorded from 11 2 and was the lowest at H1 . For combined effect, the longest plant (44.45 cm). maximum number of branches per plant (6.48) and the highest yield (23.73 t/ha) was from S3 14 2 and all the above parameters were lowest at S1 H1 . So. 50 cmx 50 cm plant spacing and harvesting interval of 15 days were more effective for growth and yield of Indian Spinach.
