Abstract:
In order to know the effect of INM on growth, yield and quality parameters and economics of potato, this study was undertaken at department of vegetable science, College of Horticulture, Mudigere. The experiment was undertaken in RCBD design and the experiment consisted of 14 treatments. The results revealed that the combination of 75% RDF + Azotobacter + PSB + KSB + MgSO4 + Micronutrient mixture resulted in the maximum sprouting (99.33%), plant height (59.33 cm), number of leaves (298), plant spread (45 and 47.33 cm, North-South and East-West, respectively), number of stems (4.79), leaf area (6296.55 cm2). AGR (0.75 g/plant/day), CGR (1.37 g/m2/day), RGR (0.00808 g/g/day), NAR (0.002100 × 10-2 g/dm2/day). Yield parameters like number of tubers per plot (118.33), tuber weight (88.67), yield per hectare (21.50 t/ha), dry matter (22%) were found maximum in the same treatment. The treatment with the combination of 75% RDF + Azotobacter + PSB + KSB + MgSO4 + Micronutrient mixture produced maximum gross income (Rs. 426530) and net income (Rs. 303638) and B:C ratio (2.47).
