Impact of Climate Change on Bulb Crops Production and Mitigation Strategies

In the twenty-first century, global warming due to climate change is the main concern of mankind. Because of shortened form of atmosphere, creation of plant crops particularly vegetables will be seriously influenced by the results of environmental change, for example, high precipitation, high temperature, dry spell, saltiness, an unnatural weather change, and so forth. Temperature plays a crucial role in various physiological process and increasing pest and disease population; hence the production of vegetable crop is temperature-dependent. The yield of bulb crop decreases by 3.5–15% as 1 °C increases in temperature and it also influences the development of seed stalk. Under such a situation price of vegetable, crop rise at a higher rate because they are highly perishable nature and affected by uninterrupted weather shifting situation. Vegetables, especially bulb crops are loaded with various antioxidants that fight against various heart disease, inflammation, reduce cholesterol level, high blood pressure, and protect against blood clots. A higher concentration of CO2 in bulb crop affect dry matter production in leaves, stems and bulbs. Various crop improvement practices like biotechnology, genetic engineering, molecular breeding and agronomic practices like cultivation under protected conditions, organic farming, and conservative tillage have potential to increase the quality as well as production under adverse conditions.
