in order to study of hydropriming, planting depth and nitrogen split application effect on yield and yield components of double cross hybrid of corn, an experiment was carried out as factorial based on randomized complete block design (rcbd) with four replications. nitrogen split application included (400 kg/ha at sowing date, 100 kg/ha at sowing date and 300 kg/ha 25 to 50 days after sowing da...

If the hard seed (seed that is viable but has an impervious coat) content of legumes greater than 20%, scarification should be considered. Scarification nicking coat to allow moisture penetrate [1]. This type treatment before sowing great importance, as it increases yield fodder plants by reducing rate rare and expensive seeds, cost sowing, accelerating germination, increasing percentage germin...

This study evaluated the effect of storage and sowing conditions on seed germination of Styrax japonicus Sieb. et. Zucc, an ornamental tree with seeds that exhibit double dormancy. The germination of freshly harvested seeds was compared with seeds that had been stored dry at 20 C for a year before sowing. After sowing, potted seeds were placed in an air-refrigerated greenhouse maintained 18.5/1...

The most important development period in cereal plants is the initial stage, that is, seed germination and early seedling development. Even if barley thought to be a partially salt-tolerant plant, it may severely affected when exposed salinity at developmental periods. Pre-treatment preparation of seeds before sowing have an agriculture. Nano-seed priming treatment new approach used increase ge...

Bottlebrush squirreltail [Elymus elymoides (Raf.) Swezey = Sitanion hystrix (Nutt.) J. G. Smith] and big squirrel-tail [Elymus multisetus (J. G. Smith) M. E. Jones = Sitanion jubatum (J. G. Smith)] have a broad geographical distribution and have been identified as high priority species for restoration of degraded rangelands in the western United States. These rangelands exhibit high annual and ...
