Abstract

A field experiment was conducted during the Rabi seasons of 2019–20 and 2020–21 at CPRI RS Gwalior (Madhya Pradesh) to study the morphological, growth, and yield characteristics of twenty-one (11 hybrids and 10 controls) Columba, MCIP/12-185, MS/12-2116, MS/10-1529, PS/06-88, P-12, MS/8-1148, PS/6-39, P-28, MS/9-2196, J/7-37, and 10 control varieties K. Bahar, K. Khyati, K. Lalima, K. Pukhraj, K. Pushakr, K. Lalit, K. Garima, K. Mohan, K. Ganga, and K. Neelkanth potato hybrids and varieties in RBD with three replications. The objective of this work was to evaluate tuber yield at medium maturity. Keeping this view in mind, the present study set out to select suitable and improved varieties of potato having superior growth and yield characteristics and better economic variability for commercial production in the Chambal region. Results revealed that the control K. lalima recorded the lowest (5.50 days) to emergence, while the highest (8.33 days) to emergence were recorded in the hybrid P-28. Final emergence among hybrids and varieties differed significantly and ranged from 91–93%. The highest stem or plant was recorded in K. Pushkar (8 stem), and the lowest stem was recorded in hybrid PS/6-39 (4.27). Maximum compound leaves/plant was recorded in control K. Pushkar (79.17), and minimum compound leaves/plant were observed in hybrid MS/8-1148 (49.72). Control Kufri Neelkanth produced the maximum (30.17 cm) leaf length, while Control K. Khyati (17.47 cm) recorded the maximum leaf width. Plant height was greatest in hybrid MS/12-2116 (75.85 cm) and lowest in hybrid Columba. The hybrids MS/12-2116, PS/06-88, and control K. Lalima (5.0) (scale 1–5) recorded the highest plant vigour, while hybrid MS/10-1529 (4.33) recorded the lowest plant vigour. The hybrid P-12 (10.75 mm) obtained the maximum diameter of the stem, while the minimum was recorded in the hybrid Columba (5.94 mm). Control K. Khyati and control K. Lalima showed maximum canopy cover (1466.67 cm2), and minimum canopy cover was recorded in control variety K. Ganga and hybrid Columba (1341.67 cm2). The hybrid P-12 recorded the minimum days (98.50 to 70% maturity), while the hybrid K. Neelkanth (104.17) recorded the maximum days. At 75 days, the maximum total and marketable tuber yield with the highest net return and B:C ratio was obtained in Hybrid MC/12-2116 (Rs. 155355 and 1.95 ) and in control K. Neelkanth (Rs. 166485 and 2.08). At 90 days maximum total and marketable tuber yield with highest net return and B: C ratio was obtained in hybrid P-28 (Rs. 202253 and 2.17) and in control K. Lalit (Rs. 235039 and 2.30). At senescence, the maximum total and marketable tuber yield with the highest net return and B: C ratio was obtained in hybrid P-28 (Rs. 377278 and 2.74) and in control K. Lalima (Rs. 359467 and 2.67). Hybrid MC/12-2116, hybrid P-28, and controls K. Neelkanth, K. Lalit, and K. Lalima were found to be suitable for cultivation in the Chambal region of Madhya Pradesh.

Conclusion

The result of the current study revealed that potato varieties and hybrids significantly affected all the treatments, which clearly indicates hybrid MC/12-2116, control K. Neelkanth, for 75 days, hybrid P-28 and control Kufri Lalit for 90 days, and hybrid P-28 and K. Lalima at senescence were most suitable for higher yield and net income. The cultivation of these hybrids and varieties will meet the requirements of potatoes located in this region, which will bring a remunerative return to the farmers.
