A field experiment was undertaken at the College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat to study the response of dill seed (Anethum graveolens L.) to irrigation and weed management practices in rabi season during 2002-03 and 2003-04. The experiment comprised of combinations of four irrigation schedules based on critical growth stages viz., I1 (irrigation at vegetative stage), I2 (irrigation at vegetative stage and at 50 % flowering stage), I3 (irrigation at vegetative stage, at 50 % flowering stage and at dough seed stage), I4 (irrigation at 0.40 IW : CPE) and seven weed management practices viz., W1 (fluchloralin 1.0 kg ha-1 as pre emergence), W2 (pendimethalin 1.0 kg ha-1 as pre emergence), W3 (metolachlor 1.0 kg ha-1 as pre emergence), W4 (oxadiargyl 100 g ha-1 as pre emergence), W5 (HW at 3 WAS and earthing up at 6 WAS), W6 : Weed free (HW at 3 and 6 WAS) and W7 (Weedy check). An experiment laid out in Split Plot Design (SPD) with four replications. Application of irrigation at 0.40 IW: CPE ration and twice hand weeding carried out at 3 and 6 weeks after sowing were noted higher growth and yield attributing characters, seed and straw yield, harvest index, test weight with maximum economic return For accruing maximum yield and economic return, dill seed crop should be irrigated either at all the critical crop growth stages or at 0.40 IW: CPE with one common irrigation with one common irrigation at time of sowing to obtain higher yield and net return .
