Safflower (<em>Carthamus tinctorius</em> L.) is an oilseed crop adapted to arid and semiarid regions. In this study, an experiment was performed to evaluate the effects of water deficiency on plant height, 1,000-grain weight, seed yield, harvest index, relative water content (RWC), oil yield, and oil content in 15 safflower genotypes. A split-plot randomized complete blocks design was arranged with three replications. Safflower plants were grown under normal irrigation and water deficit conditions in Sarvestan, Fars Province, Iran during 2016 and 2017 growing seasons. Combined analysis results indicated that water deficit stress had negative effects on all measured indices. Average seed yield declined by 65.91% (2,337.91 to 796.79 kg ha<sup>−1</sup>) due to water deficit stress. Genotype also had a significant effect on evaluated indices, and the interaction between genotype and irrigation significantly influenced all indices except plant height. Under both conditions, highest RWC, seed yield, and oil yield were observed in Dincer and PI-537598 genotypes. Maximum plant height and 1,000-seed weight in both irrigation conditions were observed in the Dincer genotype. In the normal irrigation condition, maximum harvest index and oil content were observed in the CW-74 genotype. Thus, Dincer and PI-537598 were classified as the best genotypes (based on seed yield, RWC, and oil yield) under both normal irrigation and water deficit stress conditions.

Water-deficit stress is an important concern worldwide that reduces crop yield and quality. Mustard is an important oilseed crop of India which is adversely affected by water-deficit stress in terms of growth and yield. Tolerance to water-deficit stress is correlated with the redox regulatory and antioxidant system. To mitigate negative effect of water-deficit stress, field experiment was conducted at Dholi (Muzaffarpur), Bihar during 2019-20 with an aim to study the effect of microbes on antioxidant systems in mustard grown under water-deficit stress vis-à-vis normal irrigated conditions. Pre-screened contrasting genotypes (tolerant ‘NPJ 214’ and sensitive ‘TM 179’) were sown in the experimental farm using factorial experiment in randomized block design with three replications. The treatments (12) comprised of two factors viz., genotypes (2) and microbial inoculants along with control (3) sown under normal ‘irrigated’ and ‘water-deficit stress’ conditions. Soil inoculation microbes Bacillus subtilis and Trichoderma viride was done 35 days after sowing and was compared with non-inoculated control. Results revealed that the activity of antioxidative enzymes viz., catalase and peroxidase increased under water-deficit stress; the increase was reduced by the application of B. subtilis and T. viride in both tolerant and sensitive genotypes, and more pronounced in the sensitive genotypes. Similar results were recorded with respect to lipid peroxidation and proline content. Increase in concentration of stress-induced metabolites was less in colonized plants of mustard indicating modulation of antioxidant system. The maximum ameliorating effect was observed with application of T. viride which could be an important tool in alleviating the adverse effects of water-deficit stress in mustard.

Winter Rapeseed

In order to group winter rapeseed cultivars according to evaluated traits, an experiment was conducted in the Research Greenhouse of Agriculture Faculty, University of Tabriz - IRAN. In the experiment were included 12 cultivars of winter rapeseed and 3 levels of water deficit stress. Gypsum blocks were used to monitor soil moisture. Water deficit stress was imposed from stem elongation to physiological maturity. According to the principal component analysis, five principal components were chosen with greater eigenvalue (more than 0.7) that are including 81.34% of the primeval variance of variables. The first component that explained the 48.02% of total variance had the high eigenvalue. The second component could justify about 13.64% of total variance and had positive association with leaf water potential and proline content and had negative relationship with leaf stomatal conductivity. The third, fourth and fifth components expressed around, 10.18, 4.83 and 4.68% of the total variance respectively. The third component had the high eigenvalue for plant dry weight. The fourth component put 1000-seed weight, seed yield, Silique per Plant and root dry weight against plant dry weight, chlorophyll fluorescence and leaf water potential. The fifth component had the high eigenvalue for root dry weight, root volume and 1000-seed weight.
