  • Livestock sector and green-house gases emission: Issues and options

    Leading organisations working on environmental protection, food security and climate change have realised the role of livestock in GHG emission. There are two major types of GHG emission through livestock animals. Direct GHG emission is the portion evolved directly through animal body by enteric fermentation in ruminants and urine discharge. Moreover, the decomposition of manure is also part of it. Indirect GHG emission involves the emission through fertilizer application and production AGRICULTURE IS ever augmenting sector globally and biggest contributor t…Read More

  • Weed management under changing climate

    Climate is long term aggregated conditions of weather elements prevailing in a particular region over a specified period of time. Unfortunately, man has accelerated the degradation and over-exploitation of natural-resources due to which the global climate is fluctuating at an alarming rate. Ever rising population is adding a lot of problems offering the ease to changing climate. Deforestation, industrialization, urbanization and release of green house gases have changed the temperature of the universe. These changes are offering a deviation in cropping patterns, farming systems, pests, diseases and weeds of agricul…Read More

  • Improving allelopathic potential of crops

    Allelopathy is a prominent ecological phenomenon playing a vital role in ecosystem sustainability and productivity. Scientists have recognized that it could be improvised to get benefits in crop production. Weed management, disease control, pest management, stress tolerance and growth promotion are its major fronts in agronomic preview. It is necessary to alter the innate tendency of crops to produce and release allelochemicals for better crop management. Interest is developing among researchers to modify cultivars for high allelopathic potential. Natural weed management is inevitable because of resistance agains…Read More

  • Growing vitality of phytoweapons

    WE ARE rushing through second decade of 21st century where problems are different and complex. Most of the intellectuals of the past indicated that human survival during this era will be a challenge. Present day social and economic issues of the world are justifying those alarming predictions. All the threatening forecasts are being realized in a very drastic manner. Focusing the trembling economies of modern world and devastating environmental regimes, it becomes painfully clear that humanity is at the verge of destruction. A huge portion of human population is devoid of basic needs like food, clothes and shelter. E…Read More

  • Artificial photosynthesis

    THE ROOTS of human evolution are closely linked with plant existence. The most important chemical process running in biological regimes is photosynthesis. The significance of this process can be assessed by the fact that biggest machinery providing food and oxygen to the world is dependent on this particular phenomenon. Each year green plants use to produce about one thousand billion metric tons of organic matter and over 700 billion metric tons of oxygen by using carbon dioxide. That organic matter is used as food by each and every secondary consumer including human beings. And oxygen is the only source for the process of breathing on planet. In this way phot…Read More

  • Biological nitrification inhibition – a breakthrough

    NITROGEN IS the most important element in plant nutrition beyond any doubt. Its multifunctional nature places it to the most distinguished rank among nutrients. It plays a vital role in plant metabolism, physiological activity, defense mechanism, growth, development and efficiency by influencing a number of key enzymes, precursors and metabolites. Nitrogen is most abundant gas in air (about 79 per cent) but unfortunately plants are unable to use this atomic N and thus uptake from root zone fixed in the form of nitrates, ammonium and organic acids. Major portion utili…Read More
