How does increasing soil salinity (NaCl) concentration (0g /L, 5g /L, 10g /L, 20 g /L, 30 g/L (±0.01 g)) affect the growth of maize (Zea mays) measured through stem height in cm in 15 days?SL

Criteria Feedback
- The research question is clear, measurable and focused, specifying IV (five NaCl concentrations), DV (stem height in cm) and timeframe (15 days).
- Explicit linkage between soil salinity, osmotic stress and maize yield is explained, contextualized with Trans-Nzoia farmers and national food security.
- Introduction provides extensive local and global context, quantifying salinity-affected land and yield losses with multiple references.
- A minor inconsistency in the pH change description (“increasing from 5.8–6.0 to less than 5.8”) needs verification.
- One citation in the introduction is incomplete and some statistics lack full referencing, slightly weakening the scholarly apparatus.

Criteria Feedback
- Method is detailed and repeatable with clear volumes, masses and timing, capable of generating sufficient data.
- Sampling strategy is justified, with five replicates per treatment and rationale for salinity levels (mild, moderate, high) and control treatment.
- Control of variables (soil mass, watering schedule) is outlined in a structured table.
- Risk and ethical considerations are omitted; handling of NaCl solutions and ergonomic hazards are not addressed.
- Control variables table lists “Water” twice and omits units for light intensity; standardization and specification (e.g., µmol·m⁻²·s⁻¹) are needed.
