Efficiency of Fertilizer Nitrogen in Cereal Production: Retrospects and Prospects
Weed Management in Direct‐Seeded Rice
How extensive are yield declines in long-term rice-wheat experiments in Asia?
Improving the Productivity and Sustainability of Rice-Wheat Systems of the Indo-Gangetic Plains: A Synthesis of NARS-IRRI Partnership Research
India M.N. Saha, Central Research Institute for Jute and Allied Fibres; A.K. Bhardwaj, B. Mishra, R.P. Pareek, R.K. Sharma, P.P. Singh, U.S. Singh, Y. Singh, P.C. Srivastava, R.S.L. Srivastava, G.B.…
Biological nitrogen fixation: An efficient source of nitrogen for sustainable agricultural production?
For farming systems to remain productive, and to be sustainable in the long-term, it will be necessary to replenish the reserves of nutrients which are removed or lost from the soil.
Rhizobia inoculation improves nutrient uptake and growth of lowland rice.
The results indicate that certain strains of rhizobia can promote rice growth and yield, most likely through mechanisms that involve changes in growth physiology or root morphology rather than BNF.
Chlorophyll Meter– and Leaf Color Chart–Based Nitrogen Management for Rice and Wheat in Northwestern India
Overapplication of N in cereal crops leads to low N recovery efficiency and risk of NO 3 pollution of ground water. The chlorophyll meter, also known as SPAD meter, is a simple, portable diagnostic…
Rhizobial Inoculation Influences Seedling Vigor and Yield of Rice
These studies indicate that certain strains of nonphotosynthetic diazotrophs, including rhizobia, can promote growth and vigor of rice seedlings, and this benefit of early seedling development can carryover to significantly increased grain yield at maturity.
