it is well known that sugar beet is sensitive to salinity stress at the germination stage. three separate experiments were conducted to study the effects of salinity on seed germination, plant establishment, and yield of sugar beet genotypes for screening purposes. these included: (a) a laboratory study using four water salinity levels (with ec values < 0.1 as the control, 16, 20, and 24 ds m-1...

This paper uses the establishment of federal agricultural experiment stations to provide new evidence on the effects of university research on long-term regional development. Our analysis of county-level agricultural census data from 1870 to 2000 reveals that station establishment increased local crop revenue per acre for 30-40 years, but localization effects do not persist to the present day. ...

management of a companion crop is critical to successful establishment of perennial forages (Albrecht and Hall, Weed control during alfalfa (Medicago sativa L.) establishment is 1995). a primary concern of forage producers. Companion crops and clearWeed management is important for decreasing comseeding with an herbicide are commonly used methods for establishing alfalfa. This study evaluated an...

Seeds are central to crop production, human nutrition, and food security. A key component of the performance of crop seeds is the complex trait of seed vigour. Crop yield and resource use efficiency depend on successful plant establishment in the field, and it is the vigour of seeds that defines their ability to germinate and establish seedlings rapidly, uniformly, and robustly across diverse e...

Two field experiments, organized in randomized complete block design, were conducted in 2005 and 2006 farming seasons at Nyankpala in the Northern Region of Ghana to investigate the effects of planting depth (1, 2, 4, 6 and 8 cm) and land preparation methods (flat field, mounding and ridging) on crop establishment (percentage number of established plants) and grain yield of soybean (Glycine max...

A recently completed (Nov. 2009), Cornell University project that focused on controlling weeds in strawberries during the establishment year by transplanting dormant berry plants into a killed cover crop showed great promise, but revealed a barrier. Most growers had difficulty planting through the cover crop. This resulted in slower establishment during the first month and possibly caused skips...

Rice receives a large amount of water during land preparation and the growing period, causing poor crop water productivity and lower net benefits. In wheat, excessive tillage operations delay its sowing, resulting in low yields and net returns. Dry seeding of rice and zero tillage in wheat can be expected to reduce water inputs and tillage costs compared with the conventional system of rice-whe...
