Description The experiment entitled“Effect of seed size, spacing and nitrogen on seedpotato production
cv. Kufri Bahar.” was conducted at Research Farm of the Department of Vegetable Science, CCS
Haryana Agricultural University, Hisar during winter season of 2009-10. The experiment comprising of
three seed size (25-50 g, >50-75 g and >75-100 g), three plant spacing (60x10, 60x15 and 60x20 cm)
and two nitrogen level (100 and 125 N kg/ha) was laid out in a randomized block design with three
replications keeping net plot size 3.6x3.0 m. Ten competitive plants were selected randomly from each
experimental treatment to record data on various parameters, which were influenced significantly by
different seed size, plant spacing and nitrogen levels.
The per cent plant emergence, plant height, leaves/stem, leaf area index, number of tubers up
to 25 g, >25-50 g and >50-75 g grade, total numberof tuber, weight of tuber >25-50 g and >50-75 g
grade were statistically higher with seed size >75-100 g tubers. However, the value for number of
stems per hill, leaves weight per hill, stem weightand weight of foliage, number of tubers per plot >75
g grade, weight of tubers up to 25 and >75 g and total tuber yield was maximum with >50-75 g seed
size tubers. Different plant spacing exhibited significant difference for growth and yield parameters.
The maximum value for plant height, stem/hill, leaves/stem, leaf area index , leaves weight, stem
weight, weight of foliage, number of tubers >50-75 g and >75 g grade, total number of tubers, weight
of tubers up to 25 g, >25-50 g >50-75 g, >75 g grade and total tuber yield were maximum with 60x20
cm plant spacing. However, per cent plant emergencewas found maximum with plant spacing 60x15
cm and number of tubers up to 25 g and >25-50 g grade tubers per plot were found maximum with
plant closest spacing of 60x10 cm. Effect of nitrogen level showed remarkable variation for growth and
yield parameters except per cent plant emergence. Significantly highest value was registered for plant
height, stem/hill, leaves/stem, leaf area index, leaves weight, stem weight, weight of foliage, numberof
tubers up to 25 g, >25-50 g, >50-75 g and >75 g, total number of tubers, weight of tubers up to 25 g,
>25-50 g >50-75 g and >75 g grade, total tuber yield with nitrogen 125 kg/ha. However, plant
emergence found maximum with nitrogen 100 kg /ha.
Kufri Bahar produced highest total tuber yield 437.14 q/ha when >50-75 g seed size
tubers were planted at a spacing 60x20 cm and nitrogen level 125 kg/ha which was followed
by seed size >75-100 g, plant spacing 60x15 cm and nitrogen level 100 kg/ha.
