Apre-sowing treatment was applied to black cumin (Nigella sativa L.) seeds, which were surface-sterilized and soaked for 5, 10 or 15 h in 10–6, 10–5, or 10–4M aqueous solution of gibberellic acid (GA). The potted plants were then analysed at 50, 70 and 90 days after sowing for leaf chlorophyll (Chl) content, stomatal conductance (gs), carbonic anhydrase (CA) activity, nitrate reductase (NR) act...

The objective of this study was to evaluate the effects of sowing procedures and the seed sowing rate of kudzu (Pueraria phaseoloides cv. ‘Comum’) in corn on corn plant development, forage dry matter production, weed infestation and soybean plant development and yield. The kudzu seeds were either broadcasted over the terrain or sown in furrows (in the main plots) at rates, in both cases, of 400...

Forage production is primarily limited by weather conditions under dryland production systems in Brazilian semi-arid regions, therefore sowing at the appropriate time is critical. The objectives of this study were to evaluate the CSM-CERES-Pearl Millet model from the DSSAT software suite for its ability to simulate growth, development, and forage accumulation of pearl millet [Pennisetum glaucum...

In order to elucidate the effect of sowing date on oilseed rape (Brassica napus L.) yield and yield components, three varieties including Tower, Rafal and Global were sown from November 7 to December 22, 1998-99 in four dates with 15day intervals in Dezful region. A split-plot design based on randomized complete blocks with four replications was used in which levels of sowing dates and cultivar...

introduction bean is one of the most important legumes worldwide for direct human consumption and is a rich source of protein and carbohydrates. bean is weak to compete with weed because of the retard growth at the early stages. therefore, weed control at this time plays an important role to gain high priduction. yield crop depends on weed number, and size after germination. weed control depend...

NEDKOV, N., 2007. Research on the Effect of Pre-sowing Treatment on Seed Germination of Hypericum perforatum L. Bulg. J. Agric. Sci., 13: 31-37 Trials were carried out for improvement of seed germination of St. John's Wort (Hypericum perforatum L.) based on studies of main sowing properties after treatments as follows: soaking, soaking and heating and combined seed stratification. Recommendatio...

This study investigates the hypothesis that tomtits are significantly less susceptible to 1080 poison operations when cereal rather than carrot bait applications are used, both at relatively low sowing rates. We made counts of territorial male tomtits along transects during standard 1080 possum control operations in 2001 to 2003. The transects had 3–5 kg ha sowing rates of either carrot or cere...

Studies on the function of root traits and the genetic variation in these traits are often conducted under controlled conditions using individual potted plants. Little is known about root growth under field conditions and how root traits are affected by agronomic practices in particular sowing density. We hypothesized that with increasing sowing density, root length density (root length per soi...

-An analysis of occupational incidence data for malignant melanomas and squamous-and basal-cell carcinomas of the skin in England and Wales from 1970 to 1975 is reported. The occupational pattern for melanomas of the trunk and limbs differed markedly from the pattern for melanomas of the head, face and neck. Office work was associated with a large excess of melanomas of the trunk and limbs. In ...

In view of the uneven artificial sowing, low sowing, as well as the fact that the existing seeders cannot meet the sowing requirements of Pteris vittata, this paper designed an automatic plug seeder by using the method of spraying and sowing after mixing spores and water. In order to obtain the optimum working parameters of the seeder, response surface method (RSM) was employed to desi...
