Effect of 1mM Nicotinamide adenine dinucleotide (NAD) applied as a pre-, post- or pre+post- plant drench application on plant height of tomato (Solanum lycopersicon L.) cv. HM1823 in the greenhouse; pre = NAD treatment 1 day before transplanting; post = NAD treatment 1 day after transplanting; pre+post = NAD treatment 1 day before and 1 day after transplanting; DAT = days after transplanting. Factor levels sharing the same letter within each time point do not differ significantly (P-value > 0.05), according to Tukey’s HSD.

Effect of Nicotinamide adenine dinucleotide (NAD) on soil root-knot nematode, Meloidogne incognita population in fumigated and non-fumigated beds, field trial, fall, 2020. Factor levels sharing the same letter do not differ significantly (P-value > 0.05), according to Tukey’s HSD.

Effect of Nicotinamide adenine dinucleotide (NAD) on early tomato (Solanum lycopersicon L.) fruit production at 77 DAT in fumigated and non-fumigated beds; field trial spring 2020; DAT = days after transplanting. Factor levels sharing the same letter do not differ significantly (P-value > 0.05), according to Tukey’s HSD.
