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...

introduction lentil (lens culinaris medik.) is an important legume in the mediterranean area. high protein content in lentil seed (about 22-28%) makes it as a good food source for developing countries and low-income people. in the west of iran such as kermanhah province, it is the most important pulse in rainfed systems cultivated traditionally in rotation with wheat and barley. lentil is grown...

Low temperature during reproductive stage of spring wheat causes sterility of pollen grains and reduced yield. Field experiment was conducted during the winter season in the farm of Indian Agricultural Research Institute with wheat crop to study the effect of temperature on phenology and pollen sterility of spring wheat crop. Lower mean temperature during the crop growth period led to enhanced ...

Beekeepers who use honey bees (Apis mellifera L.) for crop pollination services, or have colonies making honey on or in close proximity to agricultural crops, are concerned about the reductions of colony foragers and ultimate weakening of their colonies. Pesticide exposure is a potential factor in the loss of foragers. During 2009-2010, we assessed changes in the field force populations of 9-10...

Water Footprint Assessment is a fast-growing field of research, but as yet little attention has been paid to the uncertainties involved. This study investigates the sensitivity of and uncertainty in crop water footprint (in m3 t−1) estimates related to uncertainties in important input variables. The study focuses on the green (from rainfall) and blue (from irrigation) water footprint of produci...

Tehran is one of the densely populated metropolises located in earthquake-prone regions. Tehran, the population of which surpasses 8 million people, is the most populated area in Iran. There are historical evidences confirming that catastrophic earthquakes have destroyed the city in past years. In the present paper, our study covers all parts of Tehran because there is the potential of signific...

Suggested citation IARI (2012) Crop residues management with conservation agriculture: Potential, constraints and policy needs. Indian Foreword India being an agriculture-dominant country produces more than 500 million tons of crop residues annually. These residues are used as animal feed, for thatching of homes, and as a source of domestic and industrial fuel. A large portion of unused crop re...

An article in the Botany section of The Scientific Ravi 2012 entitled Risk Assessment of Genetically Modified Crops perpetuates a number of common myths that there are different environmental and health risks associated with genetically modified crops, including dangers of eating foreign DNA. Such viewpoints are promulgated by fringe studies and web sites that are rejected by the overwhelming m...

The food-allergy risk assessment for transgenic proteins expressed in crops is currently based on a weight-of-evidence approach that holistically considers multiple lines of evidence. This approach recognizes that no single test or property is known to distinguish allergens from nonallergens. The stability of a protein to digestion, as predicted by an in vitro simulated gastric fluid assay, cur...

The status of damage by vertebrate pests to growing and stored agricultural crops is reviewed in the light of changing patterns of agricultural practice and land use within the UK. Significant problems and existing management techniques are briefly discussed. The results of recent research by the Agricultural Department and Advisory Service (ADAS) of the Ministry of Agriculture, Fisheries and F...
