Mean values within the same column for each trait with the same lowercase letter are not significantly different according to Duncan’s new multiple range test at . Control: untreated, CaN: calcium nitrate, CaB: calcium boron, CaCl: calcium chloride, CaChe: chelated calcium, wt: wet, and gf: gram force.
