This study was aimed to the examination of the effect of tillage row spacing and bush spacing on the performance and components of Phaseou vulgaris var. (line: cos16). The investigation was conducted as cut terraces and in terms of complete random blocks in three replicates at Brujerd Agricultural Research and Natural Resources in the agricultural year 2009-2010. Here, the main terraces with th...

to study the effect of seed density and plant distance on yield and growth parameters of radish, an experiment was conducted in research of station rice at office rasht in 2008-2009. this study was set in secondary culture after rice by factorial experiment with randomized complete block design with 3 replications. treatments consisted of factorial arrangement of three seed density levels (5, 1...

vernonia galamensis cass is a huge potential industrial crop with very high content of vernolic acid in the seed oil. the experiment was carried out to determine the effect of inter- and intra- row spacing on the yield and yield related traits of vernonia galamensis cas.the experiment was conducted for two years during 2014-2015 on experimental field of wondo genet agricultural research center,...

In this study, four different type seeders were evaluated for seed spacing, depth uniformity, and plant emergence at three forward speeds (3.6, 5.4, and 7.2 km h-1). The planter types were: no-till planter, precision vacuum planter, universal planter, and semi-automatic potato planter. The sowing uniformity of the horizontal distribution of seeds was described by using the multiple index, the m...

there are varying patterns for growing different varieties of branched or non-branched sesame. this experiment was conducted during a two-year period (2000-2001) to identify the optimal practice for cultivation of the uni-branched sesame in the safi-abad agricultural research center, khuzestan province. the statistical design was set up as strip-plot in a randomized complete block with four rep...

The objective of the study was to evaluate performance a vacuum single-seed planter in field conditions optimize some operating parameters maize production. Three forward speed tractor (4.0, 5.4 and 7.9 km h-1) five target seed spacing (102, 147, 195, 247 309 mm) were evaluated by examining mean spacing, coefficient precision miss index, multiple quality feed sowing depth, deviation from row (i...

Stromatolites may be Earth's oldest macroscopic fossils; however, it remains controversial what, if any, biological processes are recorded in their morphology. Although the biological interpretation of many stromatolite morphologies is confounded by the influence of sedimentation, conical stromatolites form in the absence of sedimentation and are, therefore, considered to be the most robust rec...

Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...
