To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...

Filamentous species of Ulva are ideal for cultivation because they are robust with high growth rates and maintained across a broad range of environments. Temperate species of filamentous Ulva are commercially cultivated on nets which can be artificially 'seeded' under controlled conditions allowing for a high level of control over seeding density and consequently biomass production. This study ...

Oedema disease is one of the major diseases in pigs during the nursery period. It is caused by Shigatoxin 2e producing strains of Escherichia coli. In order to combat the disease, the metaphylactic use of colistin sulphate and zinc oxide is widely spread. Additionally, special feeding regimens such as the reduction of the amount of crude protein and the increase of the amount of crude fibre are...

succinea putris l. (mullousca: pulmonata:succineidae) were collected from the rice nurseries in mazandaran province during 2005. this species by feeding on rice seedlings leaves is another pest of growing rice in nursery. symptoms of early feeding are a row of circular continuous holes on lamina and eventually led to leave loss.the high density of snails in the nursery cause loss of large numbe...

Purpose This study provides a detailed, process-based life cycle greenhouse gas (GHG) inventory of an ornamental tree production system for urban forestry. The success of large-scale tree planting initiatives for climate protection depends on projects being net sinks for CO2 over their entire life cycle. However, previous assessments of urban tree planting initiatives have not accounted for the...

Guayule seedlinos were received fromi the federal nursery of the Emergency Guayule Project at various times of the year for use in a general study of the growth of this species under greenhouse conditions (1). Stock removed from the nursery at different times of the year showed markedly different powers of regenerationi when transplanted to soil in the greenhouse. The best growth was obtained f...

Piglets (n = 240, 11.0+/-0.1 d old, 3.93+/-0.05 kg) were allotted to one of four treatments in a 2 x 2 factorial arrangement to examine the effects of diet physical form and nursery environment during the first 14 d after weaning on growth to market weight. During the treatment period, pigs were housed (10 pigs/ pen) in either a conventional hot nursery (30 degrees C) or a segregated-temperatur...

Production of nursery crops in the US is accomplished in containerand field-growing conditions, with propagation and seedling-rearing carried out in greenhouses; 11% of the US national farm-product is represented by these crops. Container-grown crops represent 60% of the US market and represent a highly labor-intensive and thus costly segment of ornamental crop production. The USDA, NASA and th...

In pig (Sus Scrofa) production, within-batch variation in bw gain of piglets during the nursery period (up to 10 wk of age) can be high and is of high economic importance. Homogeneity of BW within batches of animals is important as it influences the efficiency of use of the grower and finisher facilities, and provides an extra value for the fattening farms. In the current study, factors for a l...

The process of diagnosis of genetic syndromes in the newborn period is carried out in the context of parental anxiety and the grief following an often-unexpected outcome after a long pregnancy. The nursery staffs invariably have a strong interest in giving the family proper information about prognosis. This article is intended to focus on an approach to the diagnosis of genetic syndromes and to...
