Abstract:
A field experiment was conducted to study the effect of integrated nutrient management practices on the growth and yield performance of African marigold cv. Pusa Narangi Gainda during Rabi 2021-22. The experiment was laid out in a randomized block design with twelve treatments replicated trice viz, 100% RDF (Inorganic), 100% RDF through FYM + Ghanjeevamrit + Azotobacter + PSB, 75% RDF + 25% FYM, 75% RDF + Ghanjeevamrit, 75% RDF + Azotobacter + PSB, 75% RDF + 25% FYM + Ghanjeevamrit, 75% RDF + 25% FYM + Ghanjeevamrit + Azotobacter + PSB, 50% RDF + 50% FYM, 50% RDF +Ghanjeevamrit, 50% RDF + Azotobacter + PSB, 50% RDF + 50% FYM + Ghanjeevamrit, 50% RDF + 50% FYM + Ghanjeevamrit + Azotobacter + PSB. Maximum growth parameters viz., plant height (99.60 cm), plant spread (63.80 cm E-W and 61.33 cm N-S), number of leaves plant^-1 (39.84), leaf area plant^-1 (75.67 cm²), number of branches (22.60 and 26.47, primary andsecondary, respectively), floral characters viz., number of flowers plant^-1 (53.20), flower diameter (55.92 mm), period of flowering (61.98 days), fresh weight of flower (320.26 g plant^-1), flower yield (8.01 kg plot^-1 and 200.17 q ha^-1) and minimum days for first flower bud appearance (48.79), days for 50% flowering (57.97 days), were recorded with application of 75% RDF + 25% FYM + Ghanjeevamrit + Azotobacter + PSB, which was on par with the application of 75% RDF + 25% FYM Ghanjeevamrit, 100% RDF (Inorganic), 100% RDF through FYM + Ghanjeevamrit + Azotobacter + PSB, 50% RDF + 50% FYM + Ghanjeevamrit + Azotobacter + PSB and 50% RDF + 50% FYM + Ghanjeevamrit but significantly superior over rest of the treatments.
