Abstract:
The present research "Effect of date of sowing and weed management on nutrient uptake by crop, nutrient depletion by weed and economics of linseed (Linum usitattissimum L.) was carried out at Experimental Farm, Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab during Rabi season of 2019-20. The experiment was laid out in split plot design with fifteen treatment combinations with three main plot treatments of Date of sowing (25th October, 04th November and 15th November) and five sub plot treatment of weed management (weed free, weedy check, pendimethalin @ 1 kg a.i./ha, clodinofop @ 60 g a.i/ha and imazethapyr @75 g a.i./ha) and all the treatments were replicated thrice. The maximum nutrient uptake by crop, gross return (₹/ha), net return (₹/ha) and B:C ratio was recorded under 04th November sowing and this was at par with 25th October sowing. However, the minimum nutrient depletion by weeds was observed under 25th October sowing which was at par with 04th November sowing. In weed management, maximum nutrient uptake by crop, minimum nutrient depletion by weeds, gross return, net return and B:C ratio was recorded under W4 - Imazethapyr @ 75 g a.i./ha which was at par with W3 - Clodinofop @ 60 g a.i./ha. However, minimum nutrient uptake by crop, maximum nutrient depletion by weeds, minimum gross return, net return and B:C ratio was observed under 15th November sowing. In weed management, weedy check plot recorded minimum nutrient uptake by crop, economics and maximum nutrient depletion by weed.
