Data collected on plant growth parameters in field experiments.

Plant growth parameter	Mode and duration of assessment
Plant height (cm)	Measured with the meter rule for shorter plants and tape measure for taller plants at 5, 8, and 11 weeks of treatment application
Number of leaves	Leaves of 6 record plants were counted after 5, 8, and 11 weeks after emergence on each plot and the mean number of leaves per plot was determined for each treatment
Plant girth (cm)	Plant girth was measured with the digital micrometer screw gauge at 5 and 8 weeks after application of treatments
Chlorophyll content	Chlorophyll content index (CCI) was measured with SPAD-502Plus electronic chlorophyll meter (Konica Minolta Optics, Japan) at weeks 5 and 8
Number and weight of fruits	Number of fruits for each plot was counted individually. The weight of the fruit for each plot was weighed on a scale
Shoot fresh weight (g)	After week 13, the plants were uprooted, shoots were separated from the roots, attached soil was washed off, and then, it was allowed to air dry for five minutes and then weighed on the weighing balance
Shoot dry weight (g)	Shoot fresh weights taken after week 13 were dried in the oven at 70°C for 72 hours and weighed
Root fresh weight (g)	After 13 weeks, the roots were abscised from the shoots and washed thoroughly then allowed to dry for five minutes and weighed on a balance
Root dry weight (g)	Root fresh weights taken after week 13 were dried in an oven at 70°C for 72 hours and weighed
