in order to evaluate row spacing and microelements spraying on yield and some morphological traits ofpeppermint, a split plot experiment was conducted based on randomized complete block design with fourreplications in sari agricultural sciences and natural resources university during 2010-2011. threelevels of row spacing (50 × 10, 50 × 20 and 50 × 30 cm) and two levels of microelements (no spra...

according to the contradictory reports of researchers, tillers may have positive or negative effect on wheat yield. thus, this study was conducted to investigate the role of tillers on wheat yield under two row spacing of 12.5 and 25 cm and four plant densities of 125, 250, 375 and 500 plants per m2, at gorgan university of agricultural sciences and natural resources farm in anbare-ololum reign...

a field experiment was conducted at wondo genet agriculture research center under irrigated condition to determine the effect of intra and inter-row spacing on growth and yield of artemisia (artemisia annua l.) during the two successive seasons of 2013 and 2014. factorial combinations of four intra-rows (40, 60, 80, 100 cm) and four inter-row plant spacing’s (60, 80, 100, 120 cm) were laid out ...

The light deficiency in the canopy is not the main factor limiting maize (Zea mays L.) production but the lower radiation use efficiency (RUE). Conservation tillage planting patterns were used to construct a sustainable agricultural system for soil protection and higher RUE. On these bases, we tried to create more uniform light distribution in crop canopy for increasing radiation use efficiency...

Low density plantings complemented by natural regeneration is an increasingly common reforestation technique to ensure growth of a sufficient number of trees from desired species while maintaining natural processes such as succession. One such form of low density planting that aims at lowering establishment costs—oak clusters—has been developed as an alternative to row planting since the 1980s ...

introduction intercropping as a common method in sustainable agricultural systems, plays an important role in increasing productivity and yield stability to improve utilization of resources )alizadeh et al., 2010). studies in different countries showed that intercropping causes increase in diversity, production and more efficient use of water resources, land, labor and nutrients and also reduce...
