Abstract:Gamma irradiation is a form of pure energy which is currently used most widely for food and waste irradiation. To evaluate the potential of gamma irradiated sludge for its suitability as a soil amendment in agriculture, field experiments were carried out in a root crop, carrot (Daucus carota). Treatments consisting of three sources of manure (Farmyard Manure (FYM), gamma‐irradiated sewage sludge and non‐irradiated sewage sludge), each at three different levels (5, 10 and 15 t ha−1), were compared. The growth parameters and yield of carrot was not significantly influenced by the three sources of manure or their different levels. Values for EC, pH, organic carbon, total N, available P and K, metallic micronutrients (Zn, Mn, Fe, Cu) and heavy metals (Ni, Cd, Pb, Co) indicate no adverse effect on soil properties.

- The objectives of International Journal of Environment and Waste Management are to establish an effective channel of communication between policy-makers, government agencies, academics and research institutions, and professionals working in the field, and to provide a forum for them to disseminate information. The international dimension is emphasised in order to overcome cultural and national barriers and to meet the needs of accelerating technological change and changes in the global economy. It will serve as a vehicle for the documentation and dissemination of what government bodies, research agencies, international bodies, universities, aid agencies, industries, and environmental scientists and professionals are doing in the areas of environmental and waste management.
