Magnitude of osmotic adjustment (i.e. leaf water, osmotic and tugor potential) was lowest and highest under FI, DI and PRD, respectively. However, PRD had lower shoot biomass and grain yield per plant as compared to FI but higher than the DI. Despite improving the WUE, PRD tended to compromise the yield of wheat crop but PRD is recommended instead of DI. Results imply that PRD treatment can be an ...

The salt-tolerant and salt-sensitive genotypes, V07096 and V05003, respectively were then grown in soil medium. Lower plant sodium contents in soil medium were also observed in V07096 variety under salt stress treatments than V05003. Salt tolerant variety also showed higher potassium contents and photosynthetic rate in salt stress soil medium. Thus plant Na+, K

Results showed that wheat in weed-free conditions had maximum biomass, and leaf area index in both the growing season as compared to weeds (A. fatua and S. Marianum) infested wheat. Therefore, management of these weeds i.e., A. fatua and S. marianum is highly desirable to a...

In this research, the net radiations were estimated as 27,428 Wm−2 throughout the wheat growth period (WGP), including (118.3 Wm−2) as shortwave and (34.63 Wm−2) as longwave radiation. Latent, soil and latent heat fluxes were estimated as 3324 Wm−2, 16,549 Wm−2, and 7554 Wm−2, respectively. Water stress during the complete WGP ranged between 0.5838 and 0.1218 from the start to t...

Photoinhibition is a significant and extremely complex phenomenon, which is basically light-induced damage to the photosynthetic machinery that principally affects the Photosystem II complex and leads to less photosynthetic productivity. A light-independent photosynthetic activity restricts the consumption of electrons produced in the early photoreactions, which appears to be the principal cause of photoinhibition by vi...
