iran is a major producer of saffron in the world. about 255 tons of saffron is produced on 70 thousands hectares of land, of which 125 tons are exported. production is practiced on small holding, using traditional cultivation practices. one of the major problems associated with saffron cultivation is soil fertility depletion during the first cultivation period, the effects of which extends for ...

A field study was conducted at three sites (S1-S3) of 500m longitudinal transect along the drain, where soil was irrigated by toxic metal rich brass and electroplating industrial effluent in suburban area of Moradabad, India. Spatial and seasonal variations of total heavy metal content in soil and their effect on physico-chemical and biological properties were studied in soil samples taken from...

the fire as one of the ecological factor has positive or negative effects on ecosystems components. therefore, this study was evaluated the effect of fire on some soil physico-chemical properties in winter rangelands of behshahr. so that two burned sites were selected in rangelands and changed rangelands to wheat and barley with two control areas (unburned) in each of them. the soil sampling wa...

The quality of roadside soil along the NH3 highway of high traffic density at MorenaM.P. was studied during 2010-11 at 12 different locations. The roadside soil was found to be highly contaminated. This is evident from the modification of the soil pH, Electrical conductance, Water holding capacity and other Physico-chemical properties when compared to natural soil. The presence of heavy metals ...

Rangeland degradation is one of the global concerns affecting the pastoralists and those who suffer from its negative environmental consequences. Grazing exclosure has been extensively used among the techniques implemented by the government to protect the fertility of threatened rangelands. The impact of exclosure has been a controversial issue; therefore, it is important to understand its effe...

The effect of soil properties like adsorption, desorption, movement and distribution of endosulfan (1, 2, 3, 4, 7, 7-hexachlorobicyclo (2, 2, 1)-2-heptene-5, 6-bisoxymethlene sulfite) in two tropical soils, sandy loam and sandy clay soil from Mysore, Karnataka state were studied respectively. The results indicated that soils with different physico-chemical properties have different effects on t...

the study comparatively assessed the impacts of farm activities on the abundance and diversity of soil arthropods and soil physico-chemical parameters of the practical year training programme (pytp) farmlands, university of ibadan, south western nigeria. soil arthropods were collected from september, 2010 to february, 2011 in five sampling sites of pytp farmlands using berlese tullgren extracti...

the oil extracted from three major canola cultivars (hyolla401, hyolla420 and rgs003) grown in golestan province was analyzed for physico-chemical properties, fatty acid composition, minerals content, and stability during 16 weeks of storage. according to the results, the highest iodine value and refractive index belonged to hyolla401. the highest saponification value was observed in hyolla420....

This research was conducted to study and classify the physico-chemicalproperties of soil, yield components of wheat and to determine the significance ofthese parameters on the grain yield formation. In this research, seven statisticalmethods consisting of simple correlation analysis (SCA), multiple linear regression(MLR), stepwise regression (SR), factor analysis (FA), principal componentanalys...
