Green manure is a soil management technique which provides several benefits to agroecosystems, improving the chemical, physical and biological quality of soil, allowing them provide different ecosystem services. Thus, purpose this work was select green manures compose multifunctional agroecosystems that services in semi-arid environment through addition biomass, C N, nutrient cycling. 29 treatm...

land degradation is a major danger which restricting different areas of iran. systematic description of the environmentfor detection of environmental changes and the human-related causes and responses is essential in land cover changestudy. use of land cover data allow detection of where certain changes occur, what type of change, as well as how theland is changing. existing systems for classif...

soil compaction has become a widespread problem in the world and is one of the factors involved in land degradation and declining crop yields, especially in the arid and semi-arid agriculture. the purpose of this study was to investigate the effects of subsoil compaction on morphological, physiological and agronomic aspects of wheat .the research was carried out in the experimental farms of anb...

BACKGROUND AND AIMS The timing of flowering and summer dormancy induction plays a central role in the adaptation of Mediterranean geophytes to changes in the length of the growth season along rainfall gradients. Our aim was to analyse the role of the variation in the responses of flowering and summer dormancy to vernalization, daylength and growth temperature for the adaptation of Poa bulbosa, ...

ABSTRACT Given the lack of information on use spontaneous plants from Caatinga biome as green manure to produce grains, present work aimed agronomically and economically optimize cowpea production for grains their components when fertilized with equitable biomass amounts hairy woodrose (Merremia aegyptia L.) roostertree (Calotropis procera Ait.) in two cropping seasons a semi-arid environment. ...

soil erosion by water is the main factor of land degradation, particularly in semi-arid regions where soil productivity is usually low and lowering soil quality can severely decrease crops yields. this study was done in an area of 900 km2 in the semi-arid agricultural region of hashtroud in northwestern iran to determine the relationship between soil productivity and soil erodibility. wheat gra...
