Effect of integrated nutrient management on growth, flowering and yield of African marigold (Tagetes erecta L.)

Abstract

An experiment was entitled “Effect of Integrated Nutrient Management on Growth, Flowering and Yield of African Marigold (Tagetes erecta L.)” was carried out during rabi, 2024-25 at Instructional Farm, School of Agricultural Sciences, Dabok, Udaipur. The experiment comprised of ten treatments viz., T1 (Control), T2 (100% RDF), T3 (75% RDF + FYM 10 t ha-1), T4 (75% RDF + Vermicompost 5 t ha-1), T5 (75% RDF + FYM 10 t ha + Bio fertilizer (Liquid consortia)), T6 (75% RDF + Vermicompost 10 t ha-1 + Bio fertilizer (Liquid consortia)), T7 (50% RDF + FYM 10 t ha-1), T8 (50% RDF + Vermicompost 5 t h-1), T9 (50% RDF + FYM 10 t h-1 + Bio fertilizer (Liquid consortia) and T10 50% RDF + Vermi compost 5 t h-1 + Bio fertilizer (Liquid consortia) with replicated three in Randomized Block Design. Marigold variety Yellow-307 was used as a test crop. The results reveled that during experiment use of different nutrient on growth, flowering and yield its effect among all treatments T6 (75% RDF + Vermicompost 10 t ha-1 + Bio fertilizer (Liquid consortia) was found to significantly increase growth, flowering, yield parameters, yield as well as economic of African marigold. It was found that maximum value of growth parameters viz., The maximum plant height (35.68 and 68.65 cm) at 60 DAT and 90 DAT, number of primary branches plant-1 (14.71), number of secondary branches plant-1 (26.55), and stem girth (1.47 cm), flowering parameters viz., minimum days taken to bud initiation (35.63 days), minimum days to 50% flowering (50.63), maximum duration of flowering (54.23), highest flower diameter (5.38 cm), The maximum number of flowers plant-1 (51.11), yield parameters and yield viz., the highest flower yield plant-1 (285.45 g)., maximum flower yield plot-1 (5.14 kg), maximum flowers yield ha-1 (21.15 t ha-1), economic parameters viz., maximum net return of (₹ 282981 ha-1) was found under T6 (75% RDF + Vermicompost 10 t ha-1 + Bio fertilizer (Liquid consortia)] and maximum B-C ratio (2.91) was found under T2 (100% RDF).
