Evaluation of Biozyme Granule and Liquid Formulation Application on Tuber Yield and Related Characters in Potato

The present investigation involves evaluation of biozyme application through granules and liquid formulation on yield and related characters of potato. It was observed that due to imbalanced nutrition and non-judicious use of fertilizers potato production is lower than potential one which further led to poor tuber size and number of tubers per plant which greatly hampers tuber yield and quality. To overcome this problem, an On Farm Trial (OFT) was conducted by K.V.K. S.A.S. Nagar (Mohali) in farmers’ field during 2020-21 to evaluate the influence of application of biozyme granule and liquid formulation on tuber yield and related characters in Potato Var. Kufri Pukhraj. The treatment combinations comprised T₁ - FP: Farmers Practice (No treatment), T₂ - Application of 20 Kg biozyme granule at the time of planting and 20 kg at the time of earthing up along with application of biozyme liquid formulation @500 ml/ha at the time of tuber formation. T₃ - Application of 40Kg biozyme granule at the time of planting and application of biozyme liquid formulation @500 ml/ha at the time of tuber formation. The results of the study revealed that yield of T₂ was found best performing (315 q/ha) followed by T₃ (295 q/ha) and T₁ (255 q/ha). It was noted that T₂ was earliest for first harvest (76 d) followed by T₃ (82 d) and T₁ (90 d). Yield increase of T₂ over control was found 23.53 per cent higher while it was higher by 15.69 per cent with T₃ over control. Benefit cost ratio for T₁, T₂ and T₃ was found to be 4.04, 4.58 and 4.33, respectively. The results led to a conclusion that for better growth and yield of potato, the crop may be supplemented with different formulations of biozyme in combination with the recommended dose of fertilizers.
