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 changing the ...
Pu, et al., stated that rice engineered to produce human blood protein (HSA) requires a lot of modified rice to be grown. This raised environmental safety concerns about gene flow . They argued that this would not be a problem because rice is a self-pollinating crop, and their test showed less than 1% of the modified gene transferred in ...
AWD method can save water by about 38% without adversely affecting rice yields. [4] This method increases water productivity by 16.9% compared with continuously flood irrigation. [ 5 ] High-yielding rice varieties developed for continuously flood irrigation rice system still produce high yield under safe AWD. [ 6 ]
In the 1960s, rice yields in India were about two tons per hectare; by the mid-1990s, they had risen to 6 tons per hectare. In the 1970s, rice cost about $550 a ton; in 2001, it cost under $200 a ton. [50] India became one of the world's most successful rice producers, and is now a major rice exporter, shipping nearly 4.5 million tons in 2006.
This is a list of obsolete technology, superseded by newer technologies. Obsolescence is defined as the "transition from available to unavailable from the manufacturer in accordance with the original specification." [1] Newer technologies can mostly be considered as disruptive innovation. Many older technologies co-exist with newer alternatives ...
Some of the oldest computer games, like 1962's Spacewar! for the PDP-1 commercial minicomputer, were developed for hardware platforms so outdated that they are virtually nonexistent today. [22] Many older games of the 1960s and 1970s built for contemporary mainframe terminals and microcomputers can only be played today through software ...

Diffusion of an innovation is the concept of how it is picked up by society, at what rate and why. [34] The diffusion of a technological innovation into society can be considered in distinct phases. [35] Pre-development is the gestation period where the new technology has yet to make an impact.
