PERIODE KRITIS KACANG HIJAU (Phaseolus aureus L.) AKIBAT PERSAINGAN DENGAN GULMA DAN MACAM PENGOLAHAN TANAH PADA TANAH MEDITERAN MERAH DI DESA SOCAH KECAMATAN SOCAH BANGKALAN
Abstrak: Mung bean is one of
leguminose plants planted in the third
order after soy bean and ground nut.
The presence of weeds on certain growth periode (critical periode) and
at certain population can cause to reduce the yield of this plant. This research aimed to study the critical
periode of mung bean as the affected by the presence of weeds on different soil
tillage. The study was carried out on
horticulture station research, Socah District, Bangkalan Regency with red
mediteran (Alfisol) soil type. The research was arranged in a randomized block
design with two factors. The first factor was the clear away weed consisted
of 8 levels and the second factor was
soil tillage method consisted two levels.
Result showed that there were significant interaction between the way in
clearing away weeds and soil tillage treatment on the plant height, leaf area,
leaf number, fresh and dry weight of plant, pod number, and dry weight of seed
of plant. Moreover, the longer weeds present in assosiation with
mung bean plant was the higher the effect of the weeds to reduce the yield. The
higher yield was resulted from plant growing on the tilled soil. The critical
periode of mung bean plant growing in the competition with weeds on untilled
and tilled soil respectivelly was between 2 and 4 weeks after planting and
between 6 and 8 weeks after planting.
