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...

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...

Agronomic research suggests Australian farmers may increase wheat yields by 13 to 47% and reduce risk of crop failures by sowing crops earlier than is currently practiced. This study investigated the potential to use remote sensing to assist in evaluating changes in farmer sowing date practices in response to research recommendations, using study paddocks in the southern Australian cropping reg...

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 order to evaluation of influence of sulphur fertilizer on grain yield and the some of physiological indices of canola, an split plot experiment based on randomized complete block design was conducted in Research Farm Islamic Azad University, Ardabil branch in 2007. Factors were: sulfur fertilizer at four levels (0 as control, 25, 50 and 75 kg S/ha) in the main plots and canola cultivars at t...
