PERFORMANCE OF BROADCAST AUS RICE+ MAIZE INTERCROPPING AS AFFECTED BY MAIZE POPULATION AND NITROGEN LEVEL (Pages : 19 - 22)

An intercropping experiment involving maize and rice was conducted at On-Farm Research Division, Bangladesh Agricultural Research Institute, Mymensingh during kharif season of 2004 to determine effect of maize as base crop on the productivity and returns from maize-rice intercropping compared with maize and rice grown as monocultures. Broadcast aus rice + maize intercropping at 100 cm×25 cm and 150 cm×25 cm spacing of maize and 0, 4, 80 and 120 kg/ha of N were applied in the study field. The dry matter and grain yield of both intercropped rice and maize increased significantly with increase in N level but maize responded more applied N than rice. Increase in maize spacing reduced the dry matter and grain yield of maize but increased those rice. N uptake in both rice and maize increased significantly with each increment in N application. Wider spacing of maize increased the N uptake of rice with corresponding decrease in the N uptake of maize. The highest land equivalent ratio (1.62), rice equivalent yield (5.31 t/ha) and return above variable cost (Tk 26,840/ha) were obtained at 120 kg N/ha and 100 cm×25 cm spacing which higher than the return (Tk 25,375/ha) and rice equivalent yield of sole maize (4.94 t/ha). Intercropping produced higher return above variable cost than sole rice (Tk 7,523/ha) regardless of spacing and N level. Download
