Salicylic acid and thiourea mitigate salinity and drought stress in wheat (Triticum aestivum)

Water and salinity stresses are the major environmental concerns limiting crop production, particularly in arid semi-arid ecologies. Focused research is required to develop mitigating strategies manage such stresses. Application of plant-bioregulators (PBRs) may be an effective option water Therefore, a field experiment was conducted during 2016–17 2017–18 at saline site NW (north-western) India assess effectiveness salicylic acid thiourea easing out adverse effect variable deficit irrigation regimes. Increasing its significantly (P<0.001) reduced all studied growth parameters, viz. plant height, stand, no. tillers, leaf area index relative rate; yield attributes like spike length, grains/spike, grain weight/spike, 1000-grain weight, specific weight. either or improved parameters comparison control proved more effective. Thiourea application by 3.96 17.36%, biological 4.21 14.82%, tillers 3.77 11.91%, weight/spike 2.83 15.17%, weight 3.72 12.66% 2.04 8.84% compared control, respectively. This might due better nutrient uptake, relations, enhanced CO2 fixation partitioning assimilates. Thus, wheat found as under stress.
