Comparative study of Abelmoschus esculentus L. and Brassica nigra (L.) W.D. Koch seed germination under Varying ph and nacl Concentrations

This study examined the germination behaviour of Abelmoschus esculentus (okra) and Brassica nigra (mustard) seeds under an array of environmental conditions to dispense information on basic plant growth requirements, germination capacity at different pH and salinity levels, and other associated effects on growth parameters during seedling development. Seeds were sown into Petri dishes containing various concentrations of PH and sodium chloride solutions .In the experiment, distilled water served as control. Germination percentage, root length, shoot length, whole seedling length, root/shoot ratio, shoot/root ratio, and vigour index were assessed by day 7, at 20°C. The study found that germination levels significantly influence vigour and yield performance. Salinity affects both water potential and water availability to germinating seeds. An evaluation of the germination environment revealed that okra differs from mustard in its optimal conditions for germination, with okra exhibiting greater sensitivity to environmental stressors. This research indicates how such findings can enhance our comprehension of the ecological requirements for these economically significant crops and illuminate the impact of abiotic stress factors on seed germination and initial seedling development. These two aspects play a crucial role in establishing crop stands, enhancing agricultural productivity, and building resilience in the face of shifting climate patterns.
