Stand establishment in pulse crops

1988
There are specific optimum requirements for each group of crops, and sometimes for individual crops or genotypes, with respect to tillage and seedbed preparation. Tillage practices affect the seed and root environment and so the germination and seedling emergence of crops, as well as plant growth and yield. The factors affected include soil temperature,

Management Options for Sugarbeet Stand Establishment

Journal of Sugarbeet Research, 1992
A large part of a sugar beet (Beta vulgaris L.) grower's cost of production is the cost of obtaining an adequate stand of weed-free sugarbeet. Field experiments were conducted at four locations in Wyoming during 1990 to demonstrate the economic benefits of planting to stand and sequential preplant and postemergence herbicide treatments com­ pared to ...

Economic analysis of stand establishment for Scots pine

Canadian Journal of Forest Research, 2006
Experimental data, a process-based forest growth model, and stand-level economic optimization were combined to investigate financial returns from investments for establishing Scots pine (Pinus sylvestris L.) stands in southern Finland. Four regeneration methods (planting, sowing, and natural regeneration with 25 or 100 seed trees·ha–1) and three ...

Stand Establishment of Winter Wheat in Oklahoma: A Survey

Journal of Production Agriculture, 1996
Timely and adequate stand establishment of winter wheat (Triticum aestivum L.) is critical in the southern Great Plains, where wheat is frequently grazed by livestock in the winter followed by grain harvest. Poor stands reduce forage yield potential.

Considerations for Stand Establishment and Early Seedling Growth in Cotton

Crops & Soils, 2022
Obtaining an adequate plant stand is an important first step towards realizing the yield potential of cotton. The stand establishment phase of crop development involves a number of different processes and can be influenced by multiple factors, some that are within the grower’s control and some that are not.

Lettuce Stand Establishment with Improved Seed Pellets

Transactions of the ASAE, 1983
ABSTRACT IN a comparison of seven new commercial lettuce seed pelleting materials Splitkote, Splitkote D, and Seedcoat showed significantly faster rates of emergence than others tested. For each day the emergence period is shortened in Imperial Valley, there are potential savings of $139,500 and a probability of more uniform sized heads at harvest.

Herbicide and Variety Effects on Sugarbeet Stand Establishment

Journal of Sugarbeet Research, 1990
(…) A possibility of a preplant herbicide X variety interaction was noted in 1988, so the number of preplant treatments and locations was expanded in 1989, with all treatments planted at one depth and treated with postemergence herbicide. (…)

Establishing Standing and Walking Behavior in a Physically Handicapped, Retarded Child

Physical Therapy, 1975
A physical therapist using reinforcement procedures worked for three months with minimal success on pulling to standing and pushing off to walk as target behaviors for a physically handicapped retarded child. The physical therapist then changed his role and used an attendant staff to work on the target behaviors in a two-and-one-half month treatment ...

Establishing Climate Change Standing: A New Approach

Pace Environmental Law Review, 2019
Climate change is one of the thorniest political, legal, and economic issues of our time. Therefore, a new legal approach to the issue is required. This Note proposes a streamlined approach for climate change standing, one that assumes injury in fact and causation for a class of discernible climate change harms.

Reforestation of burned stands: The effect of ectomycorrhizal fungi on Pinus pinaster establishment

Soil Biology and Biochemistry, 2011
The area occupied by Pinus pinaster in Portugal is rapidly diminishing because of forest fires. Ectomycorrhizal fungi form obligate, mutually beneficial associations with P. pinaster which improve plant growth and resistance to adverse conditions. The aim of this work was to assess whether native ectomycorrhizal fungi could be a useful tool in the ...
