conservation tillage, a fast growing practice in iran, is considered as a means to achieve sustainability in agricultural systems. this study was carried out to determine the effect of tillage systems (no-tillage, minimum tillage and conventional tillage ) on yield and yield components of three irrigated wheat varieties. the field experiment was conducted at the experimental station of the univ...

Crop production process utilizes input energy and produces some biomass energy as output.  During this process, greenhouse gases (GHGs) are also emitted which can make environmental risks. In this study, input and output energies, energy indices, and GHG emissions arising from inputs were estimated for wheat-cotton rotation under different tillage practices in Fars province. The study was condu...

This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...

in order to evaluate the influence of different tillage methods and autumn pea cultivars (arman, hashem, ilc-482) in first cultivation on corn forage yield (variety of single cross-704) in second cultivation, this research has been done. the experiment was conducted as split-plot in rcbd with the replication of 4 in tehran university from karaj in 2012. the main plots included different tillage...

the conservation system is one of the proper methods avoiding the loss of nutrients, soil erosion, and reduce production costs. this research was examined for studying the influences of tillage systems on the three cotton cultivars at karkandeh and hashm-abad stations in gorgan. the experiments were conducted in a randomized completely block design as split plot with three replications with fiv...
