Effect of natural farming bioformulations on growth andquality of potato (Solanum tuberosumL.)

Abstract

The present study was carried out during the rabi season of 2025-26 in the organic field of theHorticultural Research cum Instructional Farm, Department of Vegetable Science, College ofAgriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh, India. The experiment wasconducted on potato (Solanum tuberosumL.) cv. Kufri Khyati and laid out in a Randomized BlockDesign (RBD) comprising seven treatments with three replications. The treatment consisted of differentcombination of ghanjeevamrit, jeevamrit and cow urine. Among the evaluated treatments, maximumplant emergence (93.33 %), plant height at 45, 60 and 75 days after planting (DAP) (27.30, 41.31 and48.13 cm), number of shoots per plant (4.93), fresh haulm weight (163.83 g plant-1), dry haulm weight(21.30 g plant-1) was recorded under the treatment T6(Ghanjeevamrit @ 2 t ha−1+ Jeevamrit @ 500 Lha−1+Cow Urine 20% spray at 20 days interval). Among quality parameters, total soluble solids (5.11ºbrix) was significantly higher under this treatment, while reducing sugar (0.34%), non-reducing sugar(0.30%) and total sugar (0.64%) were numerically highest but statistically non-significant among treat-ments. The lowest value for growth and quality attribute was found under treatmentT1(control). Thecombined application of jeevamrit, ghanjeevamrit and foliar application of 20% cow urine may haveenhanced microbial activity, promoted nutrient mineralization and improved nutrient availability to thecrop. These synergistic effects resulted in improved growth and quality attributes of potato.
