Effect of variety, planting date and plant population on yield and quality of Snap Bean (Phaseolus vulgaris L.) seed

Creator:: Filgueiras, Tarciso de Sousa
Abstract:: The objectives of these experiments were to determine the feasibility of saving seed from snap bean fields in the Willamette Valley that have been bypassed for canning and freezing, and to study the effects of different seed production methods on yield and quality of snap bean (Phaseolus vulgaris L.). Field...

Effect of seed size, seeding rate and irrigation on yield and yield components of spring wheat (Triticum aestivum L.)

Creator:: Rotta, Benigno
Resource Type:: Masters Thesis
Full Text:: yields were averaged over varieties and seeding rates. Yield increases were due to the production of

Factors affecting stand establishment and yield of meadowfoam (Limnanthes alba Benth.)

Creator:: Nyunt, San
Abstract:: Germination of meadowfoam (Limnanthes alba Benth.) seed is inhibited by warm soil temperatures. This has led to recommendations for planting from early to mid-October when soil temperatures are below about 15°C. Objective data on the effects of planting date on stand establishment and yield are not available. These studies were...

Effect of cereal companion crops on the establishment of red fescue (Festuca rubra L.) for seed production

Creator:: Chastain, Thomas G.
Abstract:: Some perennial grass seed crops such as red fescue (Festuca rubra L.) do not produce a profitable seed crop during the first growing season. The present establishment method in Oregon for red fescue seed crops generally entails spring planting which does not satisfy vernalization requirements for seed production in the...

Effect of seed protein content on plant growth of barley and wheat

Creator:: Lopez, Arturo
Abstract:: The purpose of this study was to evaluate the effect of seed protein content on plant growth of barley (Hordeum vulgare L. ) and wheat (Triticum aestivum L. ). The effects of nitrogen application on chemical and morphological characteristics of the seed were also studied. Seeds of 'Casbon' winter barley...

Establishment of grass seed crops with cereal companion crops

Creator:: DeHaas, Jeroen A. M.
Abstract:: In conventional cropping systems in the Willamette Valley, slow establishing grass species, such as Kentucky bluegrass (Poapratensis L.) are planted in the spring and seed is not harvested until the following year. Due to increasing annual production costs, it is necessary to generate a cash return from each field each...

Effect of production methods on quality of wheat seed

Creator:: Mathenge, Felix Njeruh
Abstract:: The objective of this research was to identify the optimum cultural practices for the production of the highest quality wheat seed in Oregon. The production methods included locations, irrigation, N levels and seeding rates. The seed quality factors studied were seed weight, bushel weight, protein content and seedling vigor. Foundation...

Grass seed quality in relation to time of windrowing

Creator:: Dübbern de Souza, Francisco Humberto
Abstract:: This study was undertaken to obtain information on the quality of grass seed when windrowed at the high moisture levels necessary for obtaining maximum yields. A secondary goal was to monitor moisture and temperature fluctuations in the windrow and to relate their effects to development and deterioration of the seed....

Stimulation of bluegrass seed germination by soaking and drying treatments

Creator:: Onul, Taylan
Abstract:: The objective of this study was to develop a soaking and drying procedure to stimulate faster germination of Kentucky bluegrass (Poa pratensis L.) seed. The seeds were soaked in cheesecloth bags in nine chemical solutions. The effects of temperature and time of soaking and of aeration of the solution were...
