Crop yield is the measure of crop produced per area of land. It is an important metric to understand because it helps in food security and explains why crop produce can cost more than one year and less the following year. Crop quality indicators can be used as the measure of crop health and yield potentiality. Crop canopy and its geometric characteristics are the key indicators of crop growth and productivity.
The popularity of biostimulants in agriculture is associated with the possibility of obtaining higher yields without the need to discontinue the production of ecological crops. According to numerous scientific studies, biostimulants have a positive effect on yielding plants. The yield is usually determined as the amount of fruit obtained from one plant or plot. The yield depends on the type of biostimulant used, the dose, the method of application, and the plant variety. Increased yield is often associated with improving the quality of vegetables or fruits.
The agriculture sector of the global economy will continue to be critical to the livelihoods of individuals and the stability of the overall global economy. Since the number of arable acres is expected to decline, agricultural producers are expected to become more efficient and productive to create enough food for a growing world population. At the same time, crop production will continue to be subject to unpredictable climates, from drought to flooding to intense heat, along with other stresses.
According to FAO, the demand for cereals for food and animal feed uses is projected to reach 3 billion tonnes by 2050. Also, the advent of biofuel can cause a shortage of food in the future as it would compete heavily for agricultural produce. To meet the future productivity goals, considering environmental safety will require significant advancement of technology and products, such as biostimulants. Biostimulants can be treated as an additive to fertilizers and support the uptake of nutrients, promote plant growth, and increase tolerance to abiotic stress.
Biostimulants are the subset of biologicals that offer growers yield lift potential because nearly all crop loss is due to weather and other uncertain conditions of the environment. Biostimulants are preparations made from natural raw materials. Some of them are plant extracts such as rosemary, which stimulates the growth of tomato plants with a concentration of 1,000 ppm. It acts as a catalyst for natural metabolic processes and enhances the performance of crops in its environment by increasing plant tolerance to abiotic stress factors such as drought, extreme heat, and biotic factors such as weeds, insects, etc.
Biostimulants may be used in soil preparations (powders, granules, or solutions added to the soil) or as liquid foliar application products. Biostimulants containing humic substances and nitrogen compounds are often applied directly onto the soil, whereas various extracts from plants and seaweed are used in the form of foliar applications. Biostimulants can be introduced into the irrigation system and taken up by plants along with water.
Thus, biostimulants increase crop quality and yield by increasing nutrient uptake, tolerance to abiotic stress, and promoting physiological benefits in plants while compelling government regulation for food safety and environmental concern. These benefits increase the adoption of biostimulants across the globe, thereby driving the growth of the global biostimulants market.
Henceforth, the growing need to increase crop yield and quality has been is expected to accelerate the demand for biostimulants. The biostimulants market is expected to grow at a CAGR of 12.4% in the next seven years to be valued at $5.9 billion by 2028, according to the latest publication of Meticulous Research®.
