Online Published on 11 January, 2024. Abstract A field experiment was carried out at the Organic Research Farm, Karguan ji, Jhansi, Department of Horticulture, Institute of Agricultural Sciences, Bundelkhand University, Jhansi, Uttar Pradesh, India during rabi season 2020-21 to study the “Effect of organic nutrition on growth, yield and economics of knol-khol cv. Pusa Virat”. Application of 33 per cent each of mustard cake + PSB + Azotobacter (T6) resulted in significantly maximum growth and yield attributing parameters, consequently yield of knol-khol. The higher plant height (35.21 cm), leaves per plant (28.97), knob length (24.11 cm), knob breadth (6.59 cm), biological yield (181.79 kg ha−1), weight of knob (132.58 g), volume of knob (112.35 cc), yield of knob (148.06 q ha−1), with net return Rs. 131632 ha−1 and 2.62 B:C ratio were recorded in the above treatment. The second best treatment was T7 having 33 per cent each of neem cake + PSB + Azotobacter which yielded 143.27 q ha−1 knob i.e., 4.79 q ha−1 less as compared to T6 treatment. The knob yield in the control treatment was only 90.64 q ha−1 with a net income Rs. 92570 ha−1. Top Keywords Organic nutrition, Knol-khol, Pusa Virat. Top |
