Abstract

Experiments conducted at Coimbatore during kharif 1973 revealed that a weed free condition upto 35 days was required for getting economic yield in direct sown irriga- ted Bajra (var HB. 3). Application of atrazine at 0,5 kg a. i.fha as pre-emergence spray was found to be the best effective and economic weed control treatment under irrigated condition. For dry crop, pre-sowing application of atrazine 0.5 kg o. 1/he is recommended. Post-emergence application of 2, 4-D at 1 kg a. i/ha was not effective in controlling weed in both irrigated and dry crop.
