Abstract

To ensure the healthy growth and development of vegetative and reproductive tissues, all plants must obtain a specific amount of inorganic mineral elements from their surroundings.One of the most crucial elements that regulates the growth and development of floral crops is the availability of mineral nutrients in sufficient quantities. The current study was carried out at the Assam Agricultural University's Horticulture Experimental Farm in Jorhat, Assam, during the 2020–2021 academic year utilising a completely randomised design with seven different treatment combinations and three replications. The findings showed that mineral nutrients had a substantial impact on all growth features. The treatment T5 (RDF+ Ca 500 ppm) was the most effective in boosting all growth characteristics, including plant height (56.27 cm) ,leaf count (12.33, leaf length (53.07cm), leaf width (9.67cm), leaf area (469.23cm2), stem diameter (7.07cm), and number of pseudobulbs (2.80).T2 (RDF+ Zn 750ppm) exhibited the shortest days for inflorescence visibility (50.87), bud development (142.80), days to half bloom (146.30), and days to full bloom (148.77), as well as the greatest value for spike length (66.73cm), floret diameter (9.67cm), stalk girth (3.67cm), number of florets per spike (12.93), number of spikes per plant (2. (22.80g). For Physiological characters, treatment T2 (RDF+Zn(750ppm) was best for increasing total chlorophyll content (1.55 mg g-1 fw,), stomatal number (37.13), and stomatal size (5.80 \(\mu\) m2).
