Mineral fertilizer management of maize on farmer fields differing in organic inputs in the West African savanna (2006, unknown): “Monitoring INS, IPS, and IKS every 5–10 years with nutrient-omission plots in farmers’ fields proposed by Dobermann et al. (2003) could serve to readjust this nutrient management strategy, i.e., focusing on infields and mineral fertilizer N doses of 50–100 kg N ha 1.”
Improving nitrogen fertilization in rice by sitespecific N management. A review (2010, background): “The 1.5 t ha−1 average N response across all experiments is very low compared with the average N response of 3.0 t ha−1 observed under tropical conditions (Dobermann et al., 2003).”
Strategies for overcoming low agronomic nitrogen use efficiency in irrigated rice systems in China (2006, result): “The yield level of the zero-N control at IRRI was similar to the reported values for farmers’ fields in the Philippines and in other rice-growing countries in the tropics (Dobermann et al., 2003).”
Improving Nitrogen Fertilization in Rice by Site-Specific N Management (2011, unknown): “der tropical conditions ( Dobermann et al., 2003 ).”
Need based nitrogen management using the chlorophyll meter and leaf colour chart in rice and wheat in South Asia: a review (2010, background): “In on-farm experiments conducted at 155 locations in seven domains of Asia, Dobermann et al. (2003) observed that about 50% of rice soils had INS [53 kg ha-1 and thus no basal N application was required, while only 25% of the soils had INS \41 kg ha-1 and responded to basal N application.”
Soil Test Based Fertilizer Application Improves Productivity, Profitability and Nutrient Use Efficiency of Rice (Oryza sativa L.) under Direct Seeded Condition (2021, background): “Furthermore, fertilizer use requires knowledge of the expected GY response, which depends upon the crop nutrient requirements, nutrient supply from indigenous sources, and the fate of fertilizers applied to the soil in the short and long term [17].”
On-farm evaluation of leaf color chart for need-based nitrogen management in irrigated transplanted rice in northwestern India (2007, background): “INS represents N available from all sources (soil organic matter, organic materials, crop residues, rhizosphere N fixation, irrigation water, rainfall, etc.) to rice during the growing season (Dobermann et al. 2003).”
Establishment of threshold leaf colour greenness for need-based fertilizer nitrogen management in irrigated wheat (Triticum aestivum L.) using leaf colour chart (2012, background): “Justes et al. (1997) reported decrease in N concentration as wheat plants grew from MT stage to boot stage due to dilution of N with structural Varinderpal-Singh et al. / Field Crops Research 130 (2012) 109–119 113 differ c D b t w 3 t ( a L n ( r N a r w a i o a N season (Dobermann et al., 2003).”
Assessment of the nitrogen management strategy using an optical sensor for irrigated wheat (2011, background): “It is expected that in lighter textured soils, with potentially higher leaching problems, the three- or four-way split could be more efficient than the two-way split ( Chaudhary and Katoch 1981 ).”
