Microgreen production: A potential urban horticultural agribusiness

Abstract

The “micro-greens” refers to the stage of growth at which they are harvested, usually when their first true leaves appear. They are smaller than baby green but larger than sprouts. Measuring upto 1-3 inches in height. They are tender, immature greens that need light for photosynthesis, growing medium (soil or nutrient solution medium) and represent a 7-28 days growth cycle. Microgreens, which are young, edible plants harvested at their first true leaf stage are known for their intense flavors, vibrant colors and exceptional nutritional content. Their cultivation is particularly well-suited to urban settings due to minimal space requirements, fast growth cycles and adaptability to vertical farming systems. Compared to the baby green and mature green stages of the plant, microgreens have the highest levels of bioactive components. Maximum fresh weight, dry weight and germination percentage in radish microgreens grown using the aquaponic system plus peat moss treatmentWater soaking of seed had positive effect on all growth and yield parameters than the without soaking. Among various growing media, Soil + Coco peat (1:1) found superior in some growth parameters like, days for germination, days required for harvest, yield (g/m2) and more number of harvesting cycles. The production of microgreens presents a promising opportunity for both conventional farmers as well as aspiring entrepreneurs. It promotes healthier lifestyle and a more sustainable food system. The future of microgreens productions holds opportunities in various areas such as sustainable agricultural practices like vertical farming technology, innovative packaging solutions and expanding markets.
