Efficacy of herbicides on weed suppression in transplanted finger millet(Eleusine coracana)

摘要

A field experiment was conducted during the rainy (kharif) of 2013 at Tirupati, Andhra Pradesh to study the weed management in transplanted finger millet [Eleusine coracana (L.) Gaertn]. Pre-emergence application of oxyflourfen @ 0.1 kg a.i./ha at 3 daysafter transplanting (DAT) followed by (fb) post-emergence application of azimsulfuron @ 20 g a.i./ha applied at 20 DAT resulted in lesser weed density (11/m~2) and weed dry matter (4.5 g/ m~2), which in turn favourably influenced the grain yield (3,383kg/ha) and benefit: cost ratio (2.88) of transplanted finger millet compared to other the weed control treatments. The unweeded check recorded the maximum weed population (295/m~2) and weed dry-matter (239 g/m~2) and hence resulted in drastic yield reduction of about 47% in transplanted finger millet.
