Abstract

Production potential of potato varietiy ‘Lady Rosetta’ was evaluated at three tuber sizes viz., 20–30 mm (T1), 30–40 mm (T2) and 40–50 mm (T3) with representing the four intra-row (plant to plant) spacings 8 (S1), 12 (S2), 16 (S3) and 20 cm (S4), respectively. Plant vigour in respect of height, number of stems and leaf area index were affected significantly by the varying seed sizes as well as by the intra-row spacing. Among seed sizes, 40–50 mm (T3 treatment) recorded maximum tuber yield (294.6 q/ha), plant height (43.3 cm), leaf area index (2.94), number of stems (6.11) and tubers per plant (7.48) as compared to other treatments. Whereas in the case of spacing intra-row spacing (S1) gave higher tuber yield (274.4 q/ha) but the number of tubers and stems per plant was higher at (S1). Since most of the economic parameters were in favour of the treatments S4 and T1; hence, it proved to be the best treatment followed by others.
