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...

Optimum seeding rate and row spacing are important for uniform crop establishment harvest of quality seed. Field experiment was conducted at three locations in 2014 2015 to study the influence seed on multiplication factor yield durum wheat. Triplicate split plot design used. The highest found a 125 kg ha−1 with 10 cm but not significant rates 100 spacing, 75 20 2014, 150 Debre Zeit. At Chefe D...

Cultural management practices that reduce the off-site transport of herbicides applied to row crops are needed to protect surface water quality. A soybean [Glycine max (L.) Merr.] field study was conducted near Stoneville, MS on Sharkey clay to evaluate row spacing (50 cm vs. 100 cm) effects on metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(methoxy-1-methylethyl) acetamide] transport. One ...

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). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...

Subsoiling to a depth of 35 cm under the planting row for 3 consecutive years increased annual yields of seed cotton by 50 to 200%. Annual subsoiling was essential for maximum yields. The application of a nematicide, 1,2-dibromo-3-chloropropane (DBCP) or aldicarb, reduced the population of Hoplolaimus columbus but did not increase seed-cotton yields over subsoiling alone. Subsoiling reduced H. ...

Dry direct-seeding of rice is rapidly increasing in China, but variable planting depth associated with machine sowing can lead to low seedling emergence rates. Phenotype analysis of 621 rice accessions showed that mesocotyl length (ML) was induced by deep soil covering and was important in deep-sowing tolerance in the field. Here, we performed and compared GWAS using three types of SNPs (non-sy...

 Homand Absard Rangeland Research Station is located 70 km northeast of tehran and 15 km southeast of Damavand with an altitude of 1972 m a.s.l., an average annual rainfall of 333 mm,  and a cold semi-steppe climate. In order to compare  the seed production of Vicia villosa under different cultivation seasons and methods, the seeds were initially collected from natural habitats similar to the m...
