In the present work, olive-crop yields and olive oil physico-chemical quality were studied after three and six years of olive mill wastewater (OMW) spreading at three levels (50, 100 and 200 m3 ha-1 year-1). Olive yield showed improvements with OMW level. Insignificant difference in oil content and oil quality indices of the control and treatments amended by OMW was observed. Moreover, olive oi...

This research examines the energy use patterns and input–output analysis of cotton, groundnut in Gezira Scheme which is largest irrigated scheme Sudan. Inputs sources were determined by a face to questionnaire applied 200 farmers. For cotton crop, inputs output calculated as 27659.28MJ/ha 28084MJ/ha, respectively. Fertilizer was highest input (62.29%), followed water (28.10%). Energy efficiency...
Much animal manure is being applied to small land areas close to animal confinements, resulting in environmental degradation. This paper reports a study on the emissions of ammonia (NH3), methane (CH4), and nitrous oxide (N2O) from a pasture during a 90-d period after pig slurry application (60 m3 ha-1) to the soil surface. The pig slurry contained 6.1 kg total N m-3, 4.2 kg of total ammoniacal...
Community forests provide real benefits, especially the economic value of communities around forest, and a contribution to environmental services. One benefits is vital for survival living things because it has role in regulating micro macro climate. On other hand, forest destruction can cause climate instability. Sustainable management community become necessity due global political changes. F...
this research was conducted at the shahrood agricultural research center in 1382 and 1383 to study the effect of alternate furrow irrigation on potato yield and its economic evaluation. the experimental design was a randomize complete block design and the treatments were: every furrow irrigation (efi), fixed alternate furrow irrigation (fafi), variable alternate furrow irrigation (vafi), fixed ...
Abstract Gully mapping techniques successfully identify gullies over a large range of breadths and depths in complex landscapes but practices for estimating gully volumes need further development. gap-interpolation estimation volume does not often factor landscape microtopography the generation new surface. These approaches can thus overestimate classical volumes, averaging depressions, or unde...
