Land surface modification and crop diversification for enhancing productivity of a Vertisol
Vertisols occur extensively in centralIndiaand have high production potentials. Because of the high clay content (40-60% or more), high bulk density (1.5-1.8 Mg m-3) and related properties, these soils have high moisture storage capacity. Conversely, these soils become very hard when dry and very sticky when wet. Since last two decades, scientists, farmers and also the policy makers have be...
متن کاملRice Production and Nutrient Management in India
The demand for rice in India is projected at 128 million tonnes (M t) for the year 2012 and will require a production level of 3,000 kg/ ha...significantly greater than the present average yield of 1,930 kg/ ha. This low level of productivity can be increased substantially by growing high yielding varieties/hybrids and by increasing both the area under balanced fertilizer use and application ra...
متن کاملMaize 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...
متن کاملEnhancement of copper availability and microbial community changes in rice rhizospheres affected by sulfur.
The role of sulfur on the availability of Cu and the bacterial community in rice rhizospheres was investigated by pot experiments. With sulfur addition, pH in rhizosphere soil decreased and Mg(NO₃)₂ extractable Cu increased significantly. The bacterial community composition also changed with sulfur addition. Some specific clones having high similarity to Thiobacillus, which indicated that sulfu...
متن کاملProductivity Management in Iranian Railway by Data Envelopment Analysis
Study of various transportation indicators could be an appropriate criterion in evaluating the performance of the existing railways throughout the globe. This study was carried out to investigate the performance of rolling stock of Iranian railway using productivity analysis. In order to solve the problems, some solutions were provided by productivity management cycle steps. At the first step, ...
