Nutrient use efficiency and crop productivity of rice as influenced by dates of planting and nutrient management practices

Maize productivity and nutrient use efficiency in Western Kenya as affected by soil type and crop management

Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...

Influence of Crop Residues under Rice Planting and Nutrient Management on Soil Microbial Dynamics and Productivity of Chickpea in Vertisols

Nutrient Management for Increased Crop Productivity and Reduced Environmental Impacts

Careful management of plant nutrients is more important than ever because of volatile grain/fertilizer price ratios and public concerns about water quality impairment due to excess nutrient loss from fields. The management concepts most relevant to increase the efficacy of crop production while limiting water quality impairment are different for nitrogen (N) than for less mobile nutrients such ...

Crop Cycle Time, Yield and Quality of Maitake Grifola Frondosa as Influenced by Nutrient Supplements

Wheat bran, rye, millet and corn meal supplements used alone or in various combinations with mixed oak sawdust significantly influenced crop cycle time, biological efficiency (BE) and basidiome quality of maitake (Grifola frondosa). The combination of 10% wheat bran, 10% millet and 10% rye and the combination of 10% wheat bran plus 20% rye gave the highest and most consistent yields. The shorte...

Maximizing root/rhizosphere efficiency to improve crop productivity and nutrient use efficiency in intensive agriculture of China.

Root and rhizosphere research has been conducted for many decades, but the underlying strategy of root/rhizosphere processes and management in intensive cropping systems remain largely to be determined. Improved grain production to meet the food demand of an increasing population has been highly dependent on chemical fertilizer input based on the traditionally assumed notion of 'high input, hig...
