The impact of projected global warming on crop yields has been evaluated by indirect methods using simulation models. Direct studies the effects observed climate change growth and yield could provide more accurate information for assessing production. We analyzed weather data at International Rice Research Institute Farm from 1979 to 2003 examine temperature trends relationship between rice irrigated field experiments conducted 1992 2003. Here we report that annual mean maximum minimum...
Rice production in China has more than tripled the past five decades mainly due to increased grain yield rather planting area. This increase come from development of high-yielding varieties and improved crop management practices such as nitrogen fertilization irrigation. However, stagnation rice been observed ten years China. As its population rises, will need produce about 20% by 2030 order meet domestic needs if consumption per capita stays at current level. is not an easy task because...
ABSTRACT Since the release of IR8 in 1966, 42 additional indica rice ( Oryza sativa L.) cultivars developed by International Rice Research Institute (IRRI) for irrigated and favorable rainfed lowlands have been released Philippines. The maximum yield has reduced about 2 Mg ha −1 during past 30 yr. Empirical breeding population improvement within germplasm resulted maintenance potential tropics 10 . To break barrier, several approaches are being explored. These include development a new plant...
World population will increase 35% by 2050, which may require doubling crop yields on existing farm land to minimize expansion of agriculture into remaining rainforests, wetlands, and grasslands. Whether this is possible depends closing the gap between yield potential (Yp, without pest, disease, nutrient or water stresses, Yw under water-limited rainfed conditions) current average in both developed developing countries. Quantifying therefore essential inform policies prioritize research...
Abstract Chlorophyll meters are widely used to guide nitrogen (N) management by monitoring leaf N status in agricultural systems, but the effects of environmental factors and characteristics on estimations still unclear. In present study, we estimated relationships among SPAD readings, chlorophyll content per area for seven species grown multiple environments. There were similar between readings groups, relationship varied groups. A significant impact light-dependent chloroplast movement was...
China produces 28% of global rice supply and is currently self-sufficient despite a massive rural-to-urban demographic transition that drives intense competition for land water resources. At issue whether it will remain self-sufficient, which depends on the potential to raise yields existing land. Here we report detailed spatial analysis production in evaluate scenarios 2030. We find likely assuming current yield consumption trajectories no reduction area. A focus increasing double-rice...
Abstract Future rice systems must produce more grain while minimizing the negative environmental impacts. A key question is how to orient agricultural research & development (R&D) programs at national global scales maximize return on investment. Here we assess yield gap and resource-use efficiency (including water, pesticides, nitrogen, labor, energy, associated warming potential) across 32 cropping covering half of harvested area. We show that achieving high yields efficiencies are...
Abstract The chlorophyll meter provides a simple, quick, and nondestructive method to estimate leaf N status of rice ( Oryza sativa L.), but the linear relationship between concentration on dry‐weight basis dw ) reading differs depending developmental stage genotype. objective was determine whether prediction with can be improved by simple correction for specific weight (SLW). Leaf estimated (SPAD‐502) measured directly micro‐Kjel‐dahl procedure. Specific calculated as ratio dry area. In one...
Genetic improvement in grain yield has been intensively studied wheat ( Triticum aestivum L.), barley Hordeum vulgare oat Avena sativa maize Zea mays and soybean [ Glycine max (L.) Merr.]. Such information is limited rice Oryza L.). The objective of this study was to determine the trend cultivars–lines developed since 1966. Twelve were grown at International Rice Research Institute (IRRI) farm Philippine during dry season 1996. Seven IRRI 1998. Growth analyses performed key growth stages,...
