Fifteen tubers, five each representing small
(100g) size per
sample were drawn randomly from low (140 kg ha-1)
and high (210 kg ha-1) N treatments. Rest of the soil
nutrients particularly P and K were kept at the level
of sufficiency. Each tuber was measured for
maximum length (L), width (W) and thickness (T)
representing three different planes. Measurements
were made by using a simple potato gauge in
centimetre (cm). Maximum value across a particular
plane was taken and potato shape index (PSI) was
calculated using the formula: PSI=((L)2 /(W x T))
x100. Results showed that tuber shape did not
deviate in two doses of nitrogen and 75-80% tubers
retained oval shape followed by longer ones.
Findings suggest that tuber shape is relatively stable
at varied levels of nitrogen availability.
