“…This procedure results in a smoother surface and a more uniform shape and promotes the weight and size of seeds, which can be utilized both in the field and in the greenhouse, thereby exploiting seed planting productivity [ 39 ]. Generally, the weight increase or build-up increase after the coating is more than film coating and ranges from 8–500% ( Figure 3 ).…”

Seed germination and stand establishment are the first steps of crop growth and development. However, low seed vigor, improper seedbed preparation, unfavorable climate, and the occurrence of pests and diseases reduces the germination rate and seedling quality, resulting in insufficient crop populations and undesirable plant growth. Seed coating is an effective method that is being developed and applied in modern agriculture. It has many functions, such as improving seed vigor, promoting seedling growth, and reducing the occurrence of pests and diseases. Yet, during seed coating procedures, several factors, such as difficulty in biodegradation of coating materials and hindrance in the application of chemical ingredients to seeds, force us to explore reliable and efficient coating formulations. Biochar, as a novel material, may be expected to enhance seed germination and seedling establishment, simultaneously ensuring agricultural sustainability, environment, and food safety. Recently, biochar-based seed coating has gained much interest due to biochar possessing high porosity and water holding capacity, as well as wealthy nutrients, and has been proven to be a beneficial agent in seed coating formulations. This review presents an extensive overview on the history, methods, and coating agents of seed coating. Additionally, biochar, as a promising seed coating agent, is also synthesized on its physico-chemical properties. Combining seed coating with biochar, we discussed in detail the agricultural applications of biochar-based seed coating, such as the promotion of seed germination and stand establishment, the improvement of plant growth and nutrition, suitable carriers for microbial inoculants, and increase in herbicide selectivity. Therefore, this paper could be a good source of information on the current advance and future perspectives of biochar-based seed coating for modern agriculture.

“…Encrusting is the process of covering seeds with a small amount of adhesive and inert material to empower precise mechanical seed metering. It built a smoother surface, more uniform shape and increases size and weight of seeds that Microbial Seed Coating-An Emerging Strategy towards Organic Vegetable Production: A Review can be used in the greenhouse or the field, thus enhancing seed sowing/planting efficiency (Szemruch and Ferrari, 2013). This method is mostly adopted on crops requiring single placement of seeds and not requiring post-emergence thinning (Rui et al, 2016).…”

New revolutions have been taking place in agriculture since pre-historic times to increase agricultural production and meet the demands of rising population. The last revolution or green revolution has increased the overall production of all agricultural components but has led to several long-term environmental problems. Almost 62% of vegetables and 82% of fruits are found to have pesticide residues, which can affect our health in different ways. This have arisen the fear of eating raw fruits and vegetables and led to sublethal effects on natural enemies and pollinators. So, it is the very need of hour to look for sustainable approaches to control the plant diseases. Most of the plant pathogens are seed borne and disseminated. Thus, they affect the plants during pre-emergence stage or cause seedling damping off resulting in 100% crop loss. Under sustainable practices, microbial seed coating is an evolving precision technology. It enhances the shelf-life and activity of beneficial microbes and thereby decrease the use of harmful chemical pesticides and fertilizers. Natural products such as biochar, chitosan, peat, acacia gum, natural dyes from flowers Phutuka, Polash, Khoyar, Kodam can be used to manufacture microbial seed coats manually. Agribusiness firms Incotec, Novozymes and Monsanto have also led to developing of coated seeds laced with promising microbes. Thus, adoption of microbial seed coating can be a cost effective and efficient strategy in organic horticultural production.

“…Based on the laboratory results on germination and plantability, four coating materials (polymer A, polymer B, zeolite, and lime) at 30 and 35% buildup levels were selected for the field trails at Prosper, ND. Coating of sunflower achenes was found to improve the achene physiological quality and chemical protection (Szemruch and Ferrari, 2013). At both Prosper and Minot locations, all the coated seed treatments resulted in significantly higher live seed emergence and grain yield than XL achenes.…”

Extra‐large (XL) hybrid confection sunflower (Helianthus annuus L.) achenes are popular among snack food consumers, but these achenes perform poorly with precision planters; therefore, the option of planting coated seed from XL achenes was evaluated in this study. The objective of this paper was to evaluate the effect of various coating materials and buildup levels on live seed emergence, precision planting, stand establishment, and crop performance under field conditions. Based on the laboratory results on germination and plantability, four coating materials (polymer A, polymer B, zeolite, and lime) at 30 and 35% buildup levels were selected for the field trails at Prosper, ND. A separate smaller field study was conducted at Minot, ND, to verify the performance of coated seed under different growing conditions. At both Prosper and Minot locations, all the coated seed treatments resulted in significantly higher live seed emergence and grain yield than XL achenes. Live seed emergence of all the coated seed (93–99%) was significantly higher than the XL achenes (88%), and similar or higher than the large achenes (94%) at Prosper. Laboratory singulation of all the coated seed was superior to both XL achenes and large achenes, which contributed to uniform seed spacing in the field for the coated seed. Overall, this study showed that coating the hulled seeds substantially increased seed plantability and crop performance compared with XL achenes and even large achenes. A successful outcome of this study may extend this research to other sunflower seed sizes and possibly other crops.
