Studies on the Field Performance of True Potato Seed of Different Entries under Telangana Conditions

Abstract

The quality of seedlings obtained from a nursery influence re-establishment in the field and the eventual production of crops. The present investigation was conducted for two consecutive seasons during rabi, 2021-22 and rabi, 2022-23 at Mulugu, Sri Konda Laxman Telangana State Horticultural University for evaluation of the field performance of true potato seed. The same seedling raised media showed better performance in the main field of experiment, among the treatments, T1 i.e KP-15C3 X D-150 + Cocopeat : Vermicompost : FYM (2:1:1) was recorded the significantly highest growth parameters like plant height (25.15 cm and 47.61 cm), number of compound leaves per plant (15.05 and 28.13), leaf length (8.85 cm and 20.13 cm), leaf width (6.68 cm and 14.23 cm), leaf area (27.94 cm2 and 51.48 cm2) and stem diameter (0.60 cm and 0.82 cm) at 30 and 60 DAP respectively. Results related to yield attributing characters like number of micro tubers per plant (11.77), fresh weight of micro tubers per plant (16.21 g), number of small tubers per plant (7.46), fresh weight of small tubers per plant (44.03 g), number of medium tubers per plant (5.89), fresh weight of medium tubers per plant (171.40 g), number of large tubers per plant (2.84), fresh weight of large tubers per plant (115.28 g), total number of tubers per plant (27.95), tuber yield per plant (346.92 g), tuber yield per plot (20.82 kg/ 6 m2) and tuber yield (34.69 t/ha) was maximum in T1 treatment. It concluded that successfully tuberlets yield can be produced from seedling raised from TPS method.
