Tuberose (Polianthes tuberosa L.) stands tall as a global icon in the realm of cut flowers, cherished for its captivating fragrance and ornamental beauty. Originating from the illustrious Amaryllidacea family, this exquisite flower not only graces gardens but also holds significant economic promise in the cut flower and volatile oil industries.

Beyond its aesthetic allure, tuberose boasts a rich tapestry of utility. Its flowers find a coveted place in the perfume industry, lending their intoxicating fragrance to a myriad of fragrances. Moreover, tuberose is hailed for its medicinal properties, serving as both an emetic and diuretic agent. In traditional practices, tuberose bulbs have been utilized for their curative properties, particularly in treating pustules in infants. From vases to bouquets, tuberose flower spikes find diverse applications in floral arrangements, adding a touch of elegance to any setting.
In the quest for optimal growth and yield, horticulturists and farmers turn to natural stimulants to augment their cultivation practices. Among these, chitosan emerges as a frontrunner, offering a wealth of benefits for plant growth and health. Magarsakthi, a unique chitosan polysaccharide derived from marine ecosystems, takes center stage as a biofertilizer designed to elevate soil structure and stimulate plant growth.

Magarsakthi operates through a multi-faceted approach, leveraging its chitosan composition to enhance microbial chitinase activity. This enzymatic activity disrupts chitin-containing pests such as nematodes, insects, and fungi, tipping the rhizosphere equilibrium in favor of beneficial microorganisms while impeding pathogens. Magarsakthi’s enzymatic degradation ensures minimal impact on beneficial rhizosphere biota, fostering symbiotic interactions between plants and microbes. By bolstering the plant’s defense mechanisms and facilitating nutrient uptake, Magarsakthi promotes robust growth and resilience against pests and diseases.
Experimental data elucidates the profound impact of Magarsakthi on tuberose growth parameters. The number of days to flowering decreases gradually under the influence of Magarsakthi, signaling accelerated flower initiation and development. Additionally, plants treated with Magarsakthi exhibit enhanced height, spike length, and floret count per spike compared to untreated counterparts. These improvements translate to a significant boost in tuberose growth and yield potential, underscoring the efficacy of Magarsakthi as a potent growth stimulant.

In conclusion, Magarsakthi represents a paradigm shift in tuberose cultivation, harnessing the power of chitosan to unlock unparalleled growth and yield potential. As farmers and horticulturists embrace this natural biofertilizer, they embark on a journey towards sustainable agriculture, where productivity harmonizes with ecological stewardship. With Magarsakthi as a cornerstone of tuberose cultivation, the future holds promise for bountiful harvests and thriving landscapes adorned with the resplendent beauty of tuberose blooms.
