Seaweed or Marine macro-algae are often regarded as an underutilized bioresource, many have been used as a source of food, raw materials for industry, and therapeutic and botanical purposes for decades. Moreover, several plant growth-stimulating compounds found in seaweed and products derived from seaweed have made them popular supplements to crop production systems. This article provides an in-depth analysis of how different seaweed species and seaweed products affect the plant growth and development of fruit crops. They also increase plants' biochemical components and can alleviate abiotic stress.

As a major commercial sector of agriculture, floriculture has emerged. One of the most often used types of jasmine that is grown commercially in India is Jasminum sambac. Time and rate of fertilizers applications can be a part of a successful, economical, and eco-friendly nutrient management plan. Given the aforementioned information, the current experiment was conducted with the aim of determining the impacts of split N, P, and K fertilizer application on the economics of jasmine (Jasminum sambac) production. The experiment was depicted under Randomized Block Designed with five replications and five treatments i.e. 50%N+100%P+100%K at last week of December and 50%N in last week of June (T1), 50%N+75%P+75%K in last week of December + 25%N+25%K in last week of March + 25%N+25%P in last week of June (T2), 50%N+50%P+50%K in last week of December + 25%N+25%P+25%K in last week of March + 25%N+25%P+25%K in last week of June (T3), 50%N+50%P+50%K in last week of December + 25%N in last week of March + 25%N+50%K+50%P in last week of June (T4) and 50%N+50%P+50%K in last week of December + 25%N+50%P+50%K in last week of March + 25%N in last week of June (T5) at Navsari Agricultural University, Gujarat, India on Jasminum sambac variety Baramasi during the year 2018-19. The highest net returns (Rs. 4,11,729/ha) and Benefit cost ratio (2.71) and were recorded with the application of (T3). The application of application of RDF (120:240:120 kg/ha) in three splits (application of 50%N+50%P+50%K in last week of December + 25%N+25%P+25%K in last week of March + 25%N+25%K+25%P in last week of June) increased yield with highest net return and BCR and therefore, was economically deduced best for the production of Jasminum sambac.
