Abstract:
The present experiment was laid out in the field of the experimental area of ICAR-CPRI-RS, Maharajpura, Gwalior (M.P.) during the rabi Season of two consecutive years i.e 2020-2021 and 2021-2022. The experimental material for this study comprised 5 Hybrids and 6 controls as treatment viz., MS/11-664, CP-4409, MS/14-505, MS/14-1381, MS/13-527, Kufri Khyati, Kufri Pukhraj, Kufri Mohan, Kufri Lalit, Kufri Sindhuri. Kufri Neelkanth. The experiment was laid out in a randomized block design with three replications of each treatment. Nitrogen, phosphorus, and potassium were applied, through ammonium sulfate & urea, single super phosphate, and muriate of potash respectively. A uniform dose of 180 kg N ha-1, 80 kg P ha-1, and 120 kg K ha-1 was applied to all the plots. Haulm uprooting of the potato crop was done at 60 DAP, 75 DAP, and at senescence for the evaluation of red-skinned potatoes as per Days of emergence, Final emergence % at 30DAP, Number of stems per plant, Plant height(cm), Diameter of the stem(cm), and yield attributing parameters. At 75DAP hybrid, MS/14-505 recorded (43.11t/ha.) significantly higher tuber yield. At 90DAP hybrid MS/14-505 recorded a significantly higher tuber yield (52.92 t/ha.). At senescence, Hybrid MS/14-505 recorded a significantly higher tuber yield (73.06 t/ha.). It is also concluded that among controls at 75 DAP Kufri Lalit recorded the highest tuber yield 40.36t/ha while at 90DAP and senescence Kufri Khyati recorded the highest tuber yield 50.15t/ha. and 64.89t/ha., respectively ratio among controls at 90DAP and senescence, respectively. Hence it is concluded that Hybrid MS/14-505 was spotted best among different hybrids and controls followed by hybrid MS/14-1381 for the cultivation of red-skinned potatoes in the north central plains of India.
