Dataset of allelopathic effects of -L leaf aquatic extract on seed germination and growth of selected plant crops.

In agricultural fields that are surrounded by dunes, the tree is usually used as windbreaks. In addition, it plays a significant role in inhibiting nearby vegetation growth. In this dataset, the effect of -L leaf aquatic extract on seed germination and growth of four selected plant crops (Maize, Lentil, Mustard, and Wheat) was tested. Seed germination test and a greenhouse experiment were conducted to study the effects of aquatic leaf extract on seed germination and seedling growth. Various concentrations of leaf extract were used (0, 1.25%, 2.5%, and 5%). Results revealed that aqueous leaf extract of -L affected significantly seed germination of all selected plant crops under laboratory conditions. Both wheat and maize have a comparable reduction in root length at 2.47 cm and 2.45 cm, respectively, but show a remarkable difference in percentage at 92% and 54% respectively under the effect of 5% aqueous solution. Similarly, lentil shows the highest drop in shoot length (SL) of 69% while no significant reduction observed in Mustard (SL) at the same aqueous solution concentration (5%). In the greenhouse experiment, dried leaf powder was mixed with soil in different concentrations (0, 15, 30, and 45 g kg soil). Greenhouse experiments demonstrated that exhibited significant inhibition on wheat germination and seedling characteristics under all treatments. However, soil pH and electrical conductivity (EC) were examined and showed a relative reduction in pH and marked an increase in (EC).
