response surface models predict crop yield based on crop density and this is an important tool for evaluation competition at different density and hence selection of optimum density based on yield. in order to study intra and inter specific competition in intercropping bean (phaseolus vulgaris) and sesame (sesamum indicum), an experiment was conducted at the agricultural research station, ferdo...

The present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. The behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. Boundedness and dissipativeness of the system are e...

a two-year field experiment was carried out in semi-arid region of southern iran (shiraz), during 2007-2008 and 2009-2010 growing seasons using various mixtures of an early- (cv falat) and a middle-ripening (cv shiraz) winter wheat cultivar to evaluate the beneficial effects of inducing temporal growth heterogeneity on reduction of intra-specific competition during post-anthesis moisture stress...

abstract improving nitrogen use efficiency (nue) is an important objective of the agroecosystem management. a field experiment was conducted to study the effect of different competition patterns on nitrogen balance in the wheat agroecosystem. experimental design was split–plot based on randomized complete blocks with four replications. the main plots consisted of different nitrogen rates (i.e. ...

The CASC competitions among automated theorem provers show that there is no single system that outperforms all other systems in all domains. One reaction to this observation is the combination of several systems in a competitive (e.g., the SSCPA system) or cooperative manner (e.g., the CSSCPA and TECHS systems). Thereby, general-purpose heuristics select promising systems to be executed and pro...
