documenting the production process in agriculture includes providing all information and activities that shows the course of production from seedbed preparation stage to harvest stage. for this purpose, in present investigation all management operations performed from seedbed preparation stage to harvest stage in the studied wheat fields in 2007 and 2008 were recorded through farms survey. in t...

experiment was conducted in 2011 to evaluate the efficacy of reduced herbicide rates in combination with false seedbed for selective weed control in common bean. the experiment was carried out with a completely randomized factorial design. factors were herbicide dose (post-emergence application of imazethapyr at the rates of 0, 25, 50, 75, and 100 g a.i. ha-1) and seedbed preparation (false see...

the increasing needs for energy, its high price and its environmental impact on greenhouse gases emission and limited energy resources due to increased research on energy balance in crop production systems. the objective of this research was to compare seedbed preparation and sowing methods in wheat production in kordkoy region with respect to energy use and efficiency. fifteen wheat fields wer...

the seedbed preparation and cereal residue present due to limit of maize (zea mays l.) growing period are a major challenge in double cropping after winter cereals in iran as: shahrekord. in this research, effects of various seedbed preparation methods and crop residuea managements on vegetative growth and yield of forage maize (ksc 704) were studied in a barley-maize double cropping during 200...

the aim followed in tillage operations is the preparation of a suitable seedbed. the clod mean weight diameter (mwd) is one of the important tillage quality factors. in this study six sigma methodology was employed to improve the mwd index on the experimental farm of the university of tehran. six sigma is considered as one of the new improving process methods that has gained wide applications i...
