Effect of Environmental Variations Influence on Plant Growth in Different Protective Structures and Growing Mediums

Spinach (Spinacia oleracea L.), renowned for its nutritional content and health benefits, is widely cultivated worldwide. Traditional farming faces challenges such as heavy rain, thunderstorms, excessive solar radiation, and uncertain climates, making it difficult to feed the global population. Protected cultivation, employing structures like greenhouses, shields crop from adverse weather, ensuring stable yields. This research investigates how environmental variations influence plant growth in different protective structures and growing mediums. Experiment sites include open field, polyhouse, and net house environments, chosen for their diverse conditions. Various media, such as garden soil, cocopeat, and a blend of both, are used to fill earthen pots. Semi-savoy spinach seeds are sourced from the local market and soaked for 24 hrs before planting. The dibbling method ensures consistent seed spacing in pots. Environmental parameters like temperature, humidity, and light intensity are monitored regularly using instruments like thermometers and lux meters. Plant height, leaf quantity, and yield are measured to assess growth and productivity. After harvesting, the shoot portion is dried in an oven to determine dry weight, providing insights into yield. Data collection includes observations from different climate scenarios to evaluate the impact on plant characteristics. This comprehensive approach aims to understand how protective structures and growing mediums interact with environmental conditions to affect plant growth, offering valuable insights for agricultural practices and crop management strategies.
