Performance of Plant Spacing Using Cut Seed Tubers of Different Varieties on Growth Parameters, Yield Attributes and Yield

Aim: Potato is one of the most prominent crops to eliminate hunger and poverty at the global level. It is one of the world's most widely consumed and important food crops, providing a significant portion of the world's dietary energy and nutrients.

Methodology: The study was carried out at the research farm of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University- Hisar, India during the rabi season of the year 2021-22. The field experiment was conducted in a split-plot design with three potato varieties (Kufri Neelkanth, Kufri Bahar and Kufri Lima) and four different spacing (60×10 cm, 60×15 cm, 60×20 cm with cut tuber and 60×20 cm with whole tuber).

Results: Among different spacings and varieties, spacing 60×20 cm with whole tuber and Kufri Neelkanth was found best for plant height at 60, 75 and 90 days after planting, number of leaves/hill, leaves weight/hill (g), stem weight/hill (g), weight of fresh foliage (kg/m2) and and total tuber yield (q/ha), biological yield (q/ha), respectively. Whereas, Kufri Bahar was found maximum for the number of stems/hill (7.22) and Kufri Lima for total marketable tuber yield (374.4 q/ha).

Conclusion: The present study opens up new doors to the farmers and researchers for sustainable production of potatoes. The findings can be useful for farmers and researchers in developing effective strategies for improving the production of potato, which can have significant economic and nutritional benefits.
