Buta Singh Dhillon and M.S. Bhullar

Abstract

Turmeric is an important spice crop and India is its largest producer, however, weeds are the major problem in its cultivation. Results of present investgations revealed that integration of paddy straw mulch @ 9.0 t/ha with pendimethalin 1.0 kg or metribuzin 0.70 kg or atrazine 0.75 kg/ha proved very effective in controlling weed and increased fresh rhizome yield by 62.6, 64.8 and 63.0 %, respectively over unweeded control.
