Influence of planting geometries on tuber yield and profitability of seed potatoes (Solanum tuberosum) in north-western plains of India

The present field experiment was conducted during winter (rabi) seasons of 2018–19 and 2019–20 at ICAR-Central Potato Research Institute, Regional Station Jalandhar, Punjab to find out the suitable planting geometry dehaulming date for enhancing seed potato (Solanum tuberosum L.) yield profitability under north-western plains India. According study strongly influenced size tuber quality. Among different geometries, paired row bed significantly increased number tubers when done after 80–90 days. Maximum gross income, net returns benefit:cost ratio also observed over conventional geometry. Paired by 21.7% 18.6% control. Hence, it is concluded from that found maximizing numbers, as well getting maximum economic returns.
