The relation between agriculture and energy is very close. Agricultural sector itself is an energy user and energy supplier in the form of bio-energy (Alam et al., 2005). It uses large quantities of locally available non-commercial energies, such as seed, farmyard manure and animate energy, and commercial energies directly and indirectly in the form of electricity, diesel fuel, chemical fertili...

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 sludg...

abstract methods of tillage and organic matter affect root growth and distribution and therefore nutrient uptake by plant and its growth. this study was performed consecutive two years. tillage treatments included disk harrowing + two disk harrowings as reduced tillage (15 cm plowing depth) and moldboard plowing + two disk harrowings as conventional tillage system (30 cm plowing depth). also, t...

Experiment was conducted during 2007 growing seasons at the Field of College of Agriculture, Tarbiat Modares University, Tehran Province, Iran to study the effect of biofertilizers (Azosporillum and Azotobacter), nitrogen fertilizer (N) and farmyard manure (FYM) in various rates on the grain and biological yield, seed protein content as well as seed oil content and fatty acid composition in sun...

In cotton and cereals production systems, the most important cause of soil fertility degradation is the inappropriate crop residues management. In a long-term experiment carried out from 1982 to 2012, the effects of crop residues management (CRM) during 30 years on soil chemical properties and crops yields were evaluated in a cotton-cereals rotation. The experimental design was nonrandomized bl...

This study was conducted to investigate direct short-term impact of vermicompost on some soil biological properties by monitoring changes after addition of vermicompost as compared to farmyard manure in an alkaline soil with high lime content from semiarid Mediterranean region of Turkey. For this purpose, mixtures of soil and organic fertilizers in different doses were incubated under greenhous...

Finger millet (Eleusine coracana (L.) Gaertn) is a staple food crop grown by subsistence farmers in the semi-arid tropics of South Asia and Africa. It remains highly valued by traditional farmers as it is nutritious, drought tolerant, short duration, and requires low inputs. Its continued propagation may help vulnerable farmers mitigate climate change. Unfortunately, the land area cultivated wi...

Sorption of atrazine on soils subjected to three different organic amendments was measured using a batch equilibrium technique. A higher K(F) value (2.20 kg(-1)(mg L(-1))(-N)) was obtained for soil fertilized with compost, which had a higher organic matter (OM) content. A correlation between the K(FOC) values and the percentage of aromatic carbon in OM was observed. The highest K(FOC) value was...

recently, biological fertilizers extensively recommended because of over application of chemical fertilizer and their effects on environment and production resources. in order to study the effect of inoculate phosphate solubilization microorganisms (psm) and plant growth promoting rhizobacteria (pgpr) on nutrient use efficiency in corn [zea mays (l.) cv. sc 604] an experiment was conducted in 2...
