dc.description.abstract | The experiment entitled “Effect of spacing and nitrogen levels on seed production of potato cv. Kufri Khyati.” was conducted at Research Farm of the Department of Vegetable Science, Regional Research Station, Karnal during winter season of 2016-17. The experiment comprising of three plant spacing (60x15, 60x20 and 60x25 cm) and three nitrogen level (100, 125 and 150 N kg/ha) was laid out in a random block design with three replications keeping net plot size 3.6x3.6 m. Five competitive plants were selected randomly from each experimental treatment to record data on various parameters, which were influenced significantly by different plant spacing and nitrogen levels. The per cent plant emergence, plant height, number of shoots per hill, number of tubers >25-50 g, >50- 75 g and >75 g grade, yield of tuber up to 25 g, >25-50 g, >50-75 g and >75 g grade, weight of foliage, yield of seed size tuber, dry matter content of foliage and tubers were statistically higher with nitrogen dose of 150 kg/ha. However, the value for number of tubers per plot up to 25 g grade and harvest index were maximum with nitrogen dose of 125 kg/ha. Different plant spacing exhibited significant difference growth and yield parameters. The maximum value for plant emergence, plant height, number of shoots per hill, weight of foliage, number of tubers up to 25 g, >25-50 g, >50-75 g and >75 g grade, yield of tubers up to 25 g, >50-75 g and >75 g grade, dry matter content of foliage and tubers, yield of seed size tubers were maximum with 60x20cm plant spacing. However, yield of tubers >25-50 g was found maximum with plant spacing 60x25 cm and harvest index found maximum with plant spacing 60x15 cm. Significantly highest value was registered for leaf area index, total number of tubers per plot, total number of tubers per hectare, total tuber yield and biological yield with nitrogen 150 kg/ha in combination with spacing of 60x20 cm. Effect of spacing and nitrogen level showed remarkable variation for growth and yield for all the parameters. Kufri Khyati produced highest total tuber yield (305.75 q/ha) when tubers were planted at a spacing 60x20 cm and nitrogen level 150 kg/ha which was followed by total tuber yield of 298.06 q/ha at plant spacing 60x25 cm and nitrogen level 150 kg/ha. | en_US |
