Abstract:
A field experiment entitled “Comparative study on yield of different varieties of potato (Solanum tuberosum L.) in Manipur condition” was conducted during rabi season of 2014-15 at the Research Farm of College of Agriculture, Central Agricultural University, Imphal, Manipur. The treatment consists of Kufri Jyoti (T₁), Kufri Kanchan (T₂), Kufri Himalini (T₃), Aberchaibi (T₄), Kufri Giridhari (T₅) and Kufri Shailja (T₆) with four replications under Randomized Block design. Observations on yield parameters such as number of tubers per plant, fresh weight of tubers per plant (g), tuber yields (q/ha) and Harvest index (%) were recorded for testing the significance of variance of the different treatments. The number of tubers per plant was significantly higher in Kufri Kanchan (T₂), which was recorded 10.86 followed by Kufri Jyoti (T₁) which was recorded 10.49 at the time of harvesting. The highest fresh weight of tubers per plant was observed in Kufri Kanchan (130.86 and 264.15) and followed by Kufri Jyoti (121.39 and 248.70) and Kufri (110.88 and 235.35) at 60 and 90 DAS respectively. Among these varieties highest yield was obtained from Kufri Kanchan (176.10 q/ha) and the highest harvest index was recorded in Kufri Jyoti with a value of 65.94%.
