Abstract
Agricultural Research Station, University of Agricultural Sciences, Dharwad
dunng kharif 2003 and 2004 to study the effect of seed tuber sise, haulm
cu tmg, mtra row spacing, nutrient levels, growth retardants and its
methods of application besides micronutrient application and mulching on
growth and yield of potato Cv, Kufri Pukhraj and Kufri Jyoti.
The results indicated that among the varieties, Kufri Pukhraj was
aignincantly superior (19.74 t ha-, over Kufri Jyoti (18.74 t ha-) studied
under Northern Transitional Zone of Karnataka. The per plant (338.18 g)
and per ha (17.94.t) tuber yield was more with medium size (31-40 g) seed
tuber followed by 41-50 g (337.28 g and 17.83 t) and >50 g size seed tuber
(333.11 g and 17.58 t).
Seed tuber treatment with ZnSOr (0.05 %) recorded maximum total
number (8.42) of tubers per plant and total tuber yield (20.62 t) per ha
compared to CuSO, (0.05 %) and MgS04 (0.05 %). The closer intra row
spacing of 5 cm recorded higher total number of tubers per plant (7.89) and
total tuber yield per ha (23,40 t). Further, it was found that the paddy straw
mulch performed better (19.97 t ha->) compared to polythene (19,12 t ha-)
and no mulch (18.64 t ha-i) treatments.
