Bhal region of Gujarat under conserved soil moisture condition in the rabi season of 2018-19-to 2020-21 to determine the effect of levels of nitrogen and seed rate on production of durum wheat with the objective of to find out suitable nitrogen level and seed rate of durum wheat (GADW-3) for Bhal region of Gujarat under conserved soil moisture condition. Moisture received during the rainy season and conserved as such. The experiment was laid out in randomized block design (Factorial) with three replication with twelve (3 levels of seed rate & 4 levels of nitrogen) treatments combination comprising of three treatments of seed rate viz; S1: 90 kg ha, S2: 100 kg ha and S3: 110 kg and four levels of nitrogen viz; N1: 40 kg N/ha (20 kg N basal + 20 kg N at CRI), N2: 40 kg N/ha (8 kg N basal + 16 kg N at CRI + 16 kg N at 45 DAS), N3: 60 kg N/ha (30kg N at basal + 30 kg n at CRI) and N4: 60 kg N/ha (12 kg N at basal + 24 kg N at CRI + 24 kg N at 45 DAS) and apply two restricted irrigation at 21 and 45 days after sowing. Result of three year pooled analysis of experiment recorded significantly higher growth and yield parameters with 90 kg seed rate per hector viz; plant height (cm) at harvest (114.98), tiller conversion index (%) (92.63), ear length (cm) at harvest (10.13), no. of grain per ear (54.84) and test weight (56.33). The same treatment produced significantly higher grain kg per hector (3419) whereas, straw yield was found non-significant but statically higher straw yield kg per hector was reported with S3 treatment (4682). In case of nitrogen levels, 60 kg nitrogen per hector were recorded significantly higher data of plant height (cm) at harvest (116.53), ear length (cm) at harvest (10.51), grain per ear at harvest (56.23), test weight (57.01), tiller conversion index (%) (94.42), grain yield () (3514 kg/ha) & straw yield (4857 kg/ha). As far as economics was concerned, higher net return and BCR were realized with 90 kg seed rate per hector and 60 kg nitrogen per hector under conserved moisture condition with two restricted irrigation.

during the rabi seasons of the years 2017-18 and 2018-19 to determine the response of meteorological indices on seed soaking and foliar sprays of stress mitigating bio-regulators under conserved soil moisture conditions in durum wheat. The experiment comprised of four treatments of seed soaking viz; No seed soaking (S0), Seed soaking with water (S1), Seed soaking with 100 ppm Salicylic acid (S2) and Seed soaking with 500 ppm Thiourea (S3) and four treatments of foliar spray viz; No spray(C0), Water spray (C1), 100 ppm Salicylic acid spray (C2) and1000 ppm Thiourea spray (C3) of stress mitigating bio-regulators on durum wheat var. GADW 3 was conducted in Randomized Block Design (Factorial). The results showed significant response for growing degree days (GDD), Helio thermal units (HTU), Helio thermal use efficiency (HTUE) to attain different phenological stages (emergence, CRI, tillering, flag leaf, heading, milking, dough and maturity). On the pooled basis, significantly higher heat use efficiency of grain yield recorded under seed soaking with salicylic acid (100 ppm) (S2) and foliar spray of salicylic acid (100 ppm) (C2) was 1.31 & 1.28 (kg/ha/ 0 C day) respectively, over no seed soaking (S0) and no foliar spray (C0). However, it was found at par with seed soaking with 500 ppm thiourea (S3) as well as 1000 ppm foliar spray of thiourea spray (C3).
