Green waste compost and steer manure did not increase potato petiole nitrate at early bulking and vine maturity (data not shown) compared to the fallow treatment, suggesting that nitrogen in these amendments mineralized too slowly for a single application to benefit a potato crop (table 3).
On the 15th DAS, germination began with the protrusion and elongation of the cotyledon petiole, with successive differentiations into primary root, leaf sheath, emerging on the side opposite to the one from where the root emerged, and the first eophyll.

Completely randomized design was used with 4 factorial (2 x 5 x 3 x 2) (Medium: MS x B5, TDZ 5 concentrations x Explants: petiole, leaf, node x Source of explants: field, in vitro) shoot regeneration experiment.
Other traits such as petiole length, leaf length and width, flower diameter, and pedicel length, though had a fairly narrow range, differed significantly (p < 0.001) among the accessions, indicating highly significant variation among the accessions.
