This is the most important topic of agriculture which is relevant to biology so in many topics related to biology students need assistance of tutors to understand that topic in a easy way. Online tutors help is one of the best tricks to get best knowledge in particular subject and to get assignment help also in that subject and others. For example Biology assignment help is also provided by them using best techniques.
A new technique to grow rice could save hundreds of billions of cubic metres of water as increasing food security, along with a study by World Wildlife Foundation.
With a center on India – a country which faces a major water crisis, thus far has the world’s largest rice cultivated region – the learning found that the system of rice intensification (SRI) method has helped add to yields by over 30% — four to five tonnes per hectare in its place of three tonnes per hectare, while via 40% less water than conventional ways.
The system is based on eight standards which are dissimilar to conservative rice cultivation. They comprise developing nutrient-rich and un-flooded nurseries in its place of flooded ones; ensuring wider spacing between rice seedlings; preferring manures or dung to synthetic fertilizers; and managing water cautiously to avoid that the plants’ roots are not flooded.
The report proposes that major rice-producing countries — for example India, China and Indonesia — convert as a minimum 25% of their current rice farming to the new system by 2025. This would not only particularly reduce the use of water but also help make sure food security. In addition, this will decrease significant amount of methane emissions. SRI Fields do not produce methane as is the case with the more conservative system of growing rice.
WWF is concentrating on sustainable agriculture endeavors for cotton, sugar and rice, a number of the most consuming crops for which optional techniques can result in a strong yield and water savings.
