Abstract
The present investigation entitled “Effect of integrated nutrient management on growth and yield of potato (Solanum tuberosum L.)” was carried out in Horticulture Research cum Instructional Farm of Barrister Thakur Chhedilal College of Agriculture and Research Station, Sarkanda, Bilaspur (C.G.), during Rabi season of Nov 2018 to Mar 2019, The field experiment was laid out in randomized block design with 3 replications and 12 different treatment combinations viz. T1 (125% RDF (187:125:125 kg ha-1 NPK), T2 (100% RDF (150:100:100 kg ha-1 NPK), T3 (75% RDF + FYM @ 7.5 t ha-1 (25% N by FYM), T4 (50% RDF + FYM @ 15 t ha-1 (50% N by FYM), T5 (75% RDF + Vermicompost @ 3.75 t ha-1 (25% N by Vermicompost), T6 (50% RDF + Vermicompost @ 7.5 t ha-1 (50% N by Vermicompost), T7 (Tuber treatment with Trichoderma @ 20 g /k + soil incorporation of Trichoderma enriched FYM @ 15 t ha-1 SOIL, T8 (Tuber treatment with Pseudomonas @ 20 g /k + soil incorporation of Pseudomonas enriched FYM @ 15 t ha-1 soil, T9 (Tuber treatment with Pseudomonas followed by Trichoderma @ 20 g /k + soil incorporation of consortia of Pseudomonas & Trichoderma enriched FYM @ 15 t ha-1 soil, T10 (Tuber treatment with consortia of Azotobacter & PSB @20 g /k + soil incorporation of consortia of Azotobacter & PSB enriched FYM @ 15 t ha-1 soil, T11 (50% RDF only FYM @ 15 t ha-1 (50% N by (FYM) and T12 (Local control), T6 (50% RDF + Vermicompost @ 7.5 t ha-1 (50% N by Vermicompost), Integrated use of synthetic fertilizers and organic manures showed the significant impact on growth and yield attributes of potato. has resulted in plant height plant height (44.13 cm), number of green leaves and number of shoots per plant (66.40 and 4.37 respectively), and crop growth rate (2.17g/m2/day,) fresh tuber weight per plant (145.67 g), and number of tuber late per plant (18.67), 70 & 90 DAS and at harvest, respectively) And most of the yield and yield attributing characters viz., number of tuber per plant (10.67) fresh tuber weight per plant (295.67 g) tuber girth (5.05 cm), marketable yield (25.99 t/ha), total tuber yield (27.36 t/ha) were observed significantly higher with the application of 50% RDF + Vermicompost @ 7.5 t ha-1 (50% N by Vermicompost) apart from this the highest net income The highest net returns (Rs. 227218.94) and benefit cost ratio (B:C ratio) (2.03) were recorded with the treatment of T1 (125% RDF (187:125:125 kg ha-1 NPK) and also followed by T6- (50% RDF + Vermicompost @ 7.5 t ha-1 (50% N by Vermicompost) (Rs. 224101.35) and benefit-cost ratio (B:C ratio) (1.78) was also a similar result.

Conclusion
1. The maximum gross return (339393.94 Rs ha-1) and net return (227218 Rs ha-1) were realized under 125% RDF followed by 50% RDF + Vermicompost @ 7.5 t ha-1 T6 and T10 which were approximately similar in gross and net return. 2. The lowest gross return (150841 ha-1) and lowest net return (42409.36 ha-1) were recorded under T9 treatment. 3. In respect of benefit-cost ratio, treatment T1 shows maximum value (2.03) which was similar to the treatment T6i.e. (1.78). Lowest B:C ratio was observed in the T9 treatment showing a value of 0.34. 4. Based on the above findings, treatment T6 stands first in position and T1 stands in second-order of preference. However, treatment T10 comes in next in order. Therefore it may be concluded that treatment 50% RDF + Vermicompost @ 7.5 t ha-1 (T6) may be preferred for nutrient management in potato.
