Abstract

Field siudies conducted at ICAR Research Complex for NEH region, Shillong during 1983 and 1984 revealed that use of alachlor 3.0 kg/ha pre-emergeoce in soybean controlled weeds (81.7% WCE) and enhanced soybean seed yield by 68 and 127% over manual weeding (1908 kg/ha) and weedy (1136 kg/ha). Pre-plant incorporation of fluchloralin and pre-emer-gence application of alachlor at reduced rates did not prove effective. Use of alachlor (3.0 kg/ha) saved 189.5, 6 1, 142.2 kg/ha NP and K, respectively as a result of effective weed control.
