| Summary: | The objectives of this research are to investigate the dynamic of weeds
community in the intecropping system corn-peanut and the land use efficiency.
Sequential cropping system at intercropping change the weeds community among a
growing crops, and the broad leaf weeds replace the dominant spesies of sedges and
grases. The weeds community grows among monoculture cropping corn differs from
the weeds community among monoculture cropping peanut and intercripping of cornpeanut.
A field experiment in replacement series was carried out with a randomizet
complete block design with five treatments and three replications. The treatments
consisted of : p0 (monoculture peanut), p1 (75% peanut + 25% corn), p2 (50% peanut
+ 50% corn), p3 (25% peanut + 75% corn) and p4 (monoculture corn).
Result of the study showed the following conclusions. Groundnut and corn
intercropping had an effect on weed succession, from initial domination of grases weed
at 3 weeks after planting groundnut (WAPG), to sedges domination at 6 WAPG, and
then broad leaves.
