Local markets, local varieties: Rising food prices and small farmers' access to seed por Smale, Melinda, Cohen, Marc J., Nagarajan, Latha

“…This “emergency” agriculture package requires carefully targeted subsidies to ensure increases in production of major foodcrops (rice, wheat, and maize) in favorable environments with good soils, moisture, and market infrastructure. Following the Green Revolution model, delivery of improved varieties of seed, fertilizers, and other inputs, along with targeted, short-term subsidies, would augment production through higher yields rather than area expansion, so that scarce land can be reserved for other crops and uses. …”

Multi-environment genomic selection in rice elite breeding lines por Nguyen, Van Hieu, Morantte, Rose Imee Zhella, Lopena, Vitaliano, Verdeprado, Holden, Murori, Rosemary, Ndayiragije, Alexis, Katiyar, Sanjay, Islam, Md Rafiqul, Juma, Roselyne U., Galvez, Hayde, Glaszmann, Jean-Christophe, Cobb, Joshua N., Bartholomé, Jérôme

“…Results: The elite lines were found to belong to the indica group and more specifically the indica-1B subgroup which gathered improved material originating from the Green Revolution. Phenotypic correlations between environments were high for days to flowering and plant height (33% and 54% of pairwise correlation greater than 0.5 ) but low for grain yield (lower than 0.2 in most cases). …”

Improving nitrogen use efficiency and reducing nitrogen surplus through best fertilizer nitrogen management in cereal production: the case of India and China por Sapkota, Tek Bahadur, Singh, Bijay, Takele, Robel

“…Estimates of maximum N output in the form of crop yield at saturating N input regimes determined from trajectories of N output as a function of total N input for 1961–2013 and 2001–13 revealed that crop and fertilizer N management for rice, wheat, and maize in India and China did not improve significantly since the Green Revolution era. As a large number of studies in India and China show that NUE can be increased by the advancement of technology front in terms of crop and fertilizer management and by reducing the fertilizer N rate without a significant reduction in the yield of crops, recommendations have been given for governments (to frame suitable policies), farmers, extension agencies, and fertilizer dealers.…”
