WEED SUPPRESSION IN JUTE FIELD BY GROWING LEAFY VEGETABLES

Abstract

The experiment was carried out at the Agronomy research farm of Sher-e-Bangla Agricultural University (SAU), Dhaka during the period from April, 2013 to August, 2013 to study the weed suppression in jute field by growing leafy vegetables. Thirteen treatment combinations were T1 = Control, jute only, spacing 30 cm, T2 = Jute 30 cm + one line jute between two adjacent line, T3 = Jute 30 cm+ jute broadcast between two adjacent jute lines, T4 = Paired row jute 15 cm apart + jute 15 cm apart between two adjacent paired rows of jute, T5 = Paired row jute 15 cm apart + Broadcast jute between two adjacent paired rows of jute, T6 = Jute 30 cm apart + one kangkong line between two adjacent jute row, T7 = Jute 30 cm apart + broadcast kangkong between two adjacent jute row, T8 = Mixed jute (4 kg/ha) and kangkong (4 kg/ha), T9 = Mixed jute (4 kg/ha) and kangkong (2 kg/ha), T10 = Paired row jute 15 cm apart + Broadcast kangkong between two adjacent paired rows of jute, T11 Paired row jute 15 cm apart + 3 rows kangkong between two adjacent paired rows of jute, T12 = Paired row jute 15 cm apart + 4 rows kangkong between two adjacent paired rows of jute, T13= Mixed jute (6 kg/ha) and kangkong (8 kg/ha), The experiment was conducted in Randomized Complete Block Design with three replications. The results of the experiment revealed that some of the crop characteristics and yield of jute and kangkong were significant due to intercropping systems. The maximum return from jute green vegetable was obtained from T4 (52514 Tk./ha). T12 showed the highest amount of kangkong yield (11581 kg/ha). The highest dry weight of fiber (3166 kg ha-1) was obtained from T10. The treatment T12 gave the highest gross return Tk.307206 per ha. Among the different treatments T12 gave the highest net return Tk.248335 per ha. The benefit cost ratio (BCR) was found to be the highest (4.22) in the treatment combination T12.
