Abstract: A field experiment was conducted at Agricultural Research Station, Anand Agricultural University, Dhandhuka (Gujarat) during two consecutive rabi seasons of 2017-18 and 2018-19 to determine the effect of seed soaking and foliar spray of stress mitigating bio-regulators on productivity of durum wheat under conserved soil moisture condition. The experiment was laid out in randomized block design (factorial) with four replications under conserve moisture condition with sixteen treatment combinations comprising of four seed soaking treatments viz; S0:no seed soaking, S1:seed soaking with water, S2:seed soaking with salicylic acid @ 100 ppm and S3:seed soaking with thiourea @ 500 ppm; and four foliar spray treatments viz; C0: no spray, C1: foliar spray water spray, C2:foliar spray with salicylic acid @ 100 ppm and C3: foliar spray with thiourea @ 1000 ppm, twice at tillering stage (40-45 DAS) and at ear emergence (65 -70 DAS) stage. Results of the two years experiment showed that seed soaking with salicylic acid @ 100 ppm recorded significantly higher growth parameters viz; plant height (at 60 and 90 DAS and at harvest) and dry matter accumulation (at 60 and 90 DAS and at harvest). Likewise, yield attributes viz, tiller conversion index, length of spike per plant, number of spikelet per spike, number of grains per spike and test weight were recorded significantly higher under seed soaking with 100 ppm salicylic acid. The same treatment produced significantly higher grain and straw yield. However, it remained at par with seed soaking with 500 ppm thiourea treatment. Foliar spray twice at tillering stage (40-45 DAS) and at ear emergence (65 -70 DAS) stage with salicylic acid @ 100 ppm observed significantly higher growth parameters viz; plant height (at 60 and 90 DAS and at harvest) as well as dry matter accumulation (at 60 and 90 DAS and at harvest). In the same way, foliar spray with 100 ppm salicylic acid, being at par with foliar spray with 1000 ppm thiourea, reported significantly higher yield attributes viz, tiller conversion index, length of spike per plant, number of spikelet per spike, number of grains per spike and test weight over no spray and water spray. The same treatment produced significantly higher grain and straw yield. As far as economics was concerned, higher net return and BCR were realized under seed soaking with 100 ppm salicylic acid and foliar spray with 100 ppm salicylic acid, followed by seed soaking and foliar application with thiourea @ 500 ppm and 1000 ppm, respectively.
