The greater Indus valley was home to Neolithic cultures starting from 7000 BCE. They formed the antecedents of the urban Harappan civilization, whose rise and decline are dated to 2600 BCE and 1900 BCE respectively. At its peak, the Harappan civilization covered an area of more than a million square kilometres, making it the largest urbanized civilization of the Bronze Age.
Among the abiotic stresses, drought is a serious limiting factor that reduces rice production and yield stability in rainfed ecosystems. Conventional breeding for drought resistance is slow in attaining progress due to poor understanding of genetic control of drought resistance.
Experiments were conducted to determine the efficacy of various vermicomposts produced from agro- and distillation-waste of medicinal and aromatic crops on hatching of eggs of Meloidogyne incognita (Kofoid and White) Chitwood and root-knot disease development in tomato.
Water characteristics of Kandla creek, monitored seasonally from 2002 to 2006 at four locations (mouth, cargo jetty, oil jetty and junction), indicated significant increases in nutrients, petroleum hydrocarbons (PHc) and phenols from anthropogenic additions, while increases in turbidity, total suspended solids (TSS) and salinity from natural effects.
India has a long coastal line of over 7500 km supporting vast habitats such as lagoons, backwaters, estuaries, coral reefs and mangrove swamps. Among them, the mangrove ecosystem commands the highest importance because of its biological productivity and specialized diversity. After coral reefs, mangrove forests have the highest productivity among the coastal wetlands.
Climate change has received unprecedented attention of the world leaders and media as well as activists, industrialists and ordinary citizens. The scientific community and the Intergovernmental Panel on Climate Change (IPCC) in particular have been pleading for action to halt global warming and the resulting climate change.
A multiple drug-resistant (amoxycillin + clavulanic acid, ampicillin, ceftazidime, ceftriaxone) Salmonella enterica serovar Virchow was detected in a fresh milk sample out of the 58 samples collected from different dairies in and around Bareilly. Although present only in one
Following the publication of the Expert Committee II (EC-II) report and the Genetic Engineering Approval Committee (GEAC) decision, approving Bt brinjal for cultivation in India, there has been considerable discussion on the topic in public fora and the media. Surprisingly, there has been very little scientific debate or discussion on this topic in India. (Correspondence)
Millets are small grained, annual, warm weather cereals that includes 8000 species within 600 genera, of which only 35 species comprising 20 genera have been domesticated. Finger millet is grown as an important food crop in many developing countries of the tropical region; mainly in Africa and Asia. It is known as ragi and mandia in Bastar region of Chhattisgarh. Millets offer both nutritional and livelihood security for human being and fodder security for diverse livestock population in dryland regions of rural India.
Study of beach morphological changes during monsoon and development of capabilities towards its prediction is of vital importance in coastal zone management. A study of the beach erosion/accretion processes during south-west monsoon and its numerical modelling is attempted in this communication for a micro-tidal and high-energy beach. Comprehensive
