abstract
The experiment entitled, “Effect of micronutrients and humic acid on growth, yield and quality of french marigold (Tagetes patula L.) cv. Local” was carried out at the Instructional Farm, Jambuvadi, Department of Floriculture and Landscaping, College of Horticulture, Junagadh Agricultural University, Junagadh (Gujarat) in season of rabi during the year October 2024 to February 2025. The experiment was laid out in as per Randomized Block Design with factorial concept with three replication and twelve treatment combinations consisting, four levels of micronutrients i.e., M0 (micronutrients grade IV 0%), M1 (micronutrients grade IV 0.5%), M2 (micronutrients grade IV 1%) and M3 (micronutrients grade IV 1.5%) and three levels of humic acid i.e., H0 (humic acid 0%), H1 (humic acid 0.2%) and H2 (humic acid 0.4%). The result of experiment revealed that among the different levels of micronutrients, (M3) micronutrients grade IV (1.5%) recorded better result for the growth and flowering parameters as compared to other treatments. Among the humic acid acid levels, (H2) humic acid (0.4%) recorded better result for the growth and flowering parameters as compared to other treatments. In case of interaction, treatment combination of micronutrients (1.5%) with humic acid (0.4%) well performed in plant height (37.12 cm).
