Effect of Chemical and Cultural Weed Management Practices in Groundnut (Arachis hypogaea, L.)

摘要

A field investigation was carried out on integrated weed management in groundnut. In groundnut the results revealed that application of pendimethalin @ 1000 g a.i. ha~(-1) fb imazethapyr @ 75 ga.i. ha~(-1) fb 1 inter cultivation at 35 days after sowing effectively reduced the weed density and weed dry weight at all the stages there by recording higher weed control efficiency. It also recorded significantly higher yield attributes in groundnut over all other treatments viz., pod yield (21.81 q ha~(-1)), haulm yield (24.96 q ha~(-1)) and B:C ratio (3.17) against weedy check.
