Thus, soil amendment of biochar from crop straw could be adopted as a unique ecological engineering measure to reduce N2O emission while enhancing soil fertility and sustaining rice productivity in rice ecosystems.
Efficient introgression of resistance genes (Bph1, bph2, Bph3, Bph14, Bph15, Bph18, Bph20, and Bph21) into elite rice cultivars by marker-assisted selection together with strategic deployment of these genes can be an important approach to develop stable resistance to BPH and sustain rice production in the tropical and temperate rice growing regions.
"The 3000 genomes will help us explore new genes needed to create new adaptive varieties; this is becoming increasingly important to sustain rice productivity and to ensure food security under the impact of climate change," says Hei Leung, a plant geneticist at the International Rice Research Institute (IRRI) in Los Baños, the Philippines, and one of the scientists involved in the project.
Sustaining rice production relies on the intelligent use of rice diversity.
Consequently, breeding cultivars with multiple disease resistance would help sustain rice productivity.
Women are provided trained in business management and life skills to sustain rice-selling businesses.
First, the higher YN in hybrid rice cultivars was driven more by higher Y0 than by ∆YN, and therefore greater use of N fertilizers is not needed for more hybrid rice production so much as making improvements in soil fertility should be the focus for sustained hybrid rice production.
In order to sustain Basmati rice cultivation, it is pertinent to continuously improve the iconic rice variety such as PB 1121, and efforts are already underway to pyramid resistance to bacterial blight, blast and bakanae diseases.
Nor were there vast marshes, like those which sustain the rice plantations of lowland Carolina, or cane fields, as in Louisiana.
