The Rayalaseema region of Andhra Pradesh is characterized by a semi-arid climate, posing challenges for the cultivation of marigolds, especially in terms of achieving optimal growth, flowering quality, and yield. Marigold (Tagetes spp.) is a popular ornamental plant known for its vibrant flowers and significant economic value, especially in the floriculture industry.

Plant growth regulators (PGRs) are known to influence various physiological processes in plants, including cell division, elongation, flowering, and stress tolerance. By applying specific PGRs, it is possible to enhance the growth and development of marigolds, potentially leading to better flowering quality and higher yields.

This study aims to evaluate the efficacy of different PGRs on Marigold cv. L3 grown in the Rayalaseema region. The focus will be on determining the optimal concentration and application method of PGRs to achieve significant improvements in plant height, number of branches, flower size, flower weight, and overall yield.

The research will involve a controlled field experiment where marigold plants will be treated with various PGRs, including auxins, gibberellins, and cytokinins, among others. The performance of the plants will be measured and compared to a control group that receives no PGR treatment.

By understanding the response of Marigold cv. L3 to PGRs under the specific conditions of the Rayalaseema region, the study aims to provide practical recommendations for farmers and floriculturists to optimize their marigold production, contributing to increased profitability and sustainability in the region
