Integrated Nutrient Management’s Impact on Dahlia Cultivation (Dahlia variabilis L.) cv. Zail Singh
Published in Sustainability and Agricultural & Food Science
The experiment was conducted during the winter season of 2022–2023 at the Horticultural Research Centre, SVPUA&T, Meerut, to evaluate the impact of Integrated Nutrient Management (INM) on Dahlia variabilis L. cv. Zail Singh using a Randomized Complete Block Design (RCBD) with 19 treatments and three replications. Significant differences (P < 0.05) were observed among treatments for vegetative growth, flowering, and soil parameters. Treatment T12 (50% RDF + poultry manure + Azotobacter + VAM) recorded the maximum number of primary branches (9.75), leaf area (97.75 cm²), leaf area index (0.048), chlorophyll index 55.45 mg/m²), and nitrogen index (26.62 mg/m²), showing approximately 81% improvement over the control (100% RDF). T17 (25% RDF + vermicompost + Azospirillium + VAM) produced the largest stem diameter (14.30 mm), stalk diameter (10.30 mm), and flower diameter (18.00 cm). T5 enabled early color break (6.58 days), T10 extended vase life (7.10 days), while T6 and T7 significantly enhanced soil nutrient availability, and T14–T15 improved soil organic carbon, EC, and pH. In contrast, the control (T1) consistently recorded the lowest values across traits. These findings demonstrated that integrating organic manures and bio-inoculants with reduced levels of chemical fertilizers significantly enhanced crop performance and soil health, offering a sustainable strategy for ornamental horticulture.

I am currently serving as an Assistant Professor at the Meerut Institute of Technology, Meerut. I have also served as a peer reviewer for reputable scientific journals, reviewing three manuscripts in agriculture and plant sciences. I hold a Ph.D. in Horticulture with a specialization in Floriculture and Landscaping Architecture, reflecting a strong academic foundation and a commitment to advancing agricultural sciences.
With a distinguished academic and research profile, I have received three prestigious international awards recognizing my scientific contributions, and I hold three patents that demonstrate my innovative approach and dedication to developing practical horticultural solutions. My scholarly output includes 24 research and review papers published in reputed national and international journals, 27 popular science articles, 11 book chapters, and authorship of 8 books—collectively showcasing my expertise and passion for knowledge dissemination.
Beyond publications, I have actively participated in 15 national and international conferences, where I presented my research, shared insights, and collaborated with experts from across the world. My commitments also extend beyond academics, as reflected in my Course on Computer Concepts (CCC) certification, 6 Month DLC (diploma in Landscaping in CAD), and National Service Scheme (NSS) participation, highlighting both my technical proficiency and dedication to community service.
