Ipomoea aquatica, widely known as water spinach, is a semi- aquatic, tropical plant grown as a vegetable for its tender shoots. I. aquatica is generally believed to have been first domesticated in Southeast Asia. It is widely cultivated in Southeast Asia, East Asia, and South Asia. It grows abundantly near waterways and requires little to no care.
Farmers planting rice in Cambodia. A paddy field is a flooded field of arable land used for growing semiaquatic crops, most notably rice and taro. It originates from the Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with pre-Austronesian and Hmong-Mien cultures.
An example of deep water culture in lettuce production. Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than ...
In 2015 alone, Sri Lanka’s spice exports amounted to USD 377 million, up from USD 264 million the previous year. Sri Lanka’s most famous export, cinnamon is the island’s premier spice export. Industry insiders classify the spice into two forms, Ceylon cinnamon (Cinnamomum Zeylanicum), and Cassia Cinnamon. Ceylon cinnamon is the costlier ...
Agriculture. The System of Rice Intensification ( SRI) is a farming methodology that aims to increase the yield of rice while using fewer resources and reducing environmental impacts. The method was developed by a French Jesuit Father Henri de Laulanié in Madagascar [ 1] and built upon decades of agricultural experimentation. SRI focuses on ...
Kratky method. The Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. [ 1] Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are ...
The tank cascade system ( Sinhala: එල්ලංගාව, romanized: ellaṅgāva) is an ancient Sri Lankan irrigation system. It is a network of thousands of small tanks ( Sinhala: වැව, romanized: wewa) draining to large reservoirs that store rainwater and surface runoff for later use. They make agriculture possible in the dry-zone ...
Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [ 1] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [ 1] Some common choices of structures to house vertical farming ...
