SEED PRIMING EFFECTS ON YIELD AND BIOCHEMICAL ATTRIBUTES OF CORN PLANTS UNDER SALINE WATER IRRIGATIO

In dry and semi-arid locations, salinity is a significant challenge for plant productivity.

The purpose of this plot experiment in a greenhouse was to see how seed priming with NaCl affected the growth performance, plant chemical composition, and yield of a newly selected single corn hybrid, SC. 166, at various salt levels.

Methodology: In plot tests, primed and unprimed seeds were seeded and irrigated with varied salt levels.

The findings demonstrated that irrigation with saline water had an impact on soil salinity. Corn cob yield was considerably (p 0.05) reduced by rising saline levels, similar to stover and grain yields. When comparing un-primed seed to primed seed exposed to various salinity levels, the yield drop was more pronounced in un-primed seed. As salt stress rose, the salt index (SI) decreased exponentially. However, at 2, 4, and 6 g/L NaCl, the rate of decrement was more plentiful, but at 6 and 8 g/L NaCl, the rate of decrement was reduced. SI dropped by 77.28, 70.42, and 63.00 percent on average at each salinity level, compared to 51.75 percent at the higher level. Salinity levels and seed priming had a substantial impact on the harvest index, which ranged from 23.49 to 36.44 for treatments irrigated with saline water ranging from 0 to 8 g/l NaCl, respectively.

Conclusion: The findings revealed that plants generated from primed seeds produced more chlorophyll, potassium, and proline, implying that they were more salt resistant.

To maximise germination, early growth, and yield of corn seeds, primed seeds should be placed in saline media before cultivation.
