Background & aim: Saline lands can be utilized by planting native medicinal plants tolerant to salinity. The quantity and quality these plants are changed during various seasons in agriculture systems. Thus, this study carried out under salinity stress in order to examine the effect of sowing in two seasons on growth characteristics and essential oil  components of ajowan (Carum capticum </...

To improve the adaptability and precision of slider-hole-wheel seed-metering device to meet requirements sowing, single factor simulation experiments three factors levels orthogonal were carried out based on discrete element method. The rotation speed seeding shaft, shape hole, depth hole set as experiment factors. results showed that qualified rate was highest when shaft 30 r/min, oval, 9 mm. ...

We have identified five recessive allelic mutations, mori1-1 to mori1-5, which drastically modify the shoot architecture of rice. The most remarkable feature of mori1 plants is a rapid production of small leaves and short branches. The mori1 plants are about 5 cm in height even 7 months after sowing. No reproductive growth was attained in mori1 plants even if inductive short-day treatment was a...

The physiochemical characteristics and lipid composition in fast and slow germinating sunflower (Helianthus annuus L.) seeds were studied. The quantity of phospholipids, glycolipids and sterols in cotyledons and embryonic axes in fast germinating seeds (FG embryo emerged within 24 h after sowing) increased progressively between the 1st 6th days after sowing (DAS) compared with the slow growing ...

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...

The study of the phenology of crops, although quite popular, has limitations, mainly because of frequent changes to crop varieties and management practices. Here, we present data on the phenology and yield of winter rye in western Poland collected between 1957 and 2012 from a long-term field experiment. Data were examined for trends through time and compared to climatological factors using regr...

Best management practices are often used to mitigate nutrient exports from agricultural systems. The effectiveness of these measures can vary depending on the natural attributes of the land in question (e.g., soil type, slope, and drainage class). In this paper we use a Bayesian Network to combine experiential data (expert opinion) and experimental data to compare farm-scale management for diff...
