in order to evaluate the effect of sugar beet sowing date, planting density and cultivar on solar radiation interception, a study was conducted in kamal-abad agricultural research station of sugar beet seed institute (sbsi) in 2005 and 2006. the experimental design was split-split plots based on randomized complete block design (rcbd) with three replications with two sowing dates as the main pl...

Deep-sowing is an effective measure to ensure seeds absorbing water from deep soil layer and emerging normally in arid and semiarid regions. However, existing varieties demonstrate poor germination ability in deep soil layer and some key quantitative trait loci (QTL) or genes related to deep-sowing germination ability remain to be identified and analyzed. In this study, a high-resolution geneti...

With the increasing pressure on crop production from the evolution of herbicide resistance, farmers are increasingly adopting Integrated Weed Management (IWM) strategies to augment their weed control. These include measures to increase the competitiveness of the crop canopy such as increased sowing rate and the use of more competitive cultivars. While there are data on the relative impact of th...

Mulching and nitrogen are critical drivers of crop production for smallholders of the Loess Plateau in China. The purpose of this study was to investigate the effect of mulching and nitrogen fertilizer on the soil water content, soil nitrate-N content and vertical distribution in maize root-zone. The experiment was conducted over two consecutive years and used randomly assigned field plots with...

Dryland winter wheat (Triticum aestivum L.) production plays an extremely important role in the southeast of Loess Plateau. Planting patterns have great influence on improving soil water storage and yield, should be matched with different seeding rates. In order to assess effect sowing methods drought resistance stable yield dryland wheat, a field experiment was conducted Wenxi County Wheat Exp...

introduction determining the proper time for planting under different climate depends on the factors such as rainfall, temperature and length of day which are the most important aspects of crop production. its importance is because of the severity of these effects on different genotypes to achieve potential production. because different genotypes respond differently to planting delays. sowing d...

Seed enhancement methods are applied to eliminate or decrease adverse environmental stresses effects and increase seed germination rate and vigor of rangeland plants. The aim of this study was to assess different methods of seed coating effects on germination speed of Onobrychis sativa at different sowing depths and soil moisture levels. The experiment was conducted at growth chamber to apply a...

In general, the quality of fruits depends on local conditions experienced by the fruit during its development. In cotton, fruit quality, and more specifically the quality of the fibre in the fruit, depends on interactions between fruit position in the plant architecture, temperature and agronomic practices, such as sowing time, mulching with plastic film and topping of the plant's main stem and...
