Evaluating the Competitive Abiliy of Semi-leafless Field Pea (Pisum sativum L.)
Field pea (Pisum sativum L.) is an important grain legume in western Canada. Growers can, however, be reluctant to include pulse crops such as field pea in their rotation because they are poor competitors with weeds. This thesis research was conducted to determine whether competitive differences …

HORMONAL AND GENETIC BASIS OF HEAT RESPONSE IN FIELD PEA (PISUM SATIVUM L.)
Field pea (Pisum sativum L.), a cool-season legume crop, is known for poor heat tolerance. Over the last decade, progress has been made in the understanding of the physiological damage of pea plants caused by heat stress (HS), however, knowledge of the hormonal and genetic basis of heat stress …

The isolation, modification and evaluation of field pea proteins and their applications in foods
Field pea {Pisum sativum L.) is a well established crop around the world and over the last ten years, the production of this grain has been increasing in Australia. As with other grain legumes, field pea proteins contain high levels of lysine which may be important in balancing the deficiencies of …

The effect of field pea (Pisum sativum L.) basal branching on optimal plant density and crop competitiveness
Field pea is an important crop in western Canada. The current recommended seeding rate in field pea is 88 plants m-2. As certain pea genotypes have the ability for increased branching, it may be possible for a producer to seed at a lower plant population without reduced yield or to choose a highly …

BIOCONTROL OF ROOT ROT COMPLEX IN FIELD PEA AND LENTIL AND COMPLETE GENOME ANALYSIS OF BIOCONTROL BACTERIA
… destructive disease of legumes, most notably to field pea (Pisum sativum L.) and lentil (Lens culinaris L.). It commonly occurs as root rot complex (RRC) along with other soil-borne pathogens, including Fusarium avenaceum and F. oxysporum, which collectively result in significant crop damage …

Effect Of Field Pea And Multicarbohydrase Enzymes Inclusion On Growth, Diet Digestibility, And Greenhouse Gas Emissions Of Finishing Pigs And Their Manure
Introduction of field pea into a crop rotation cycle can reduce the use of nitrogenous fertilizers. Nitrogen fertilizer production and application is one of the largest greenhouse gas (GHG) emission sources from crop production. Multicarbohydrase enzymes improve diet digestibility by breaking down …

EFFECTS OF CO-INOCULATION OF ARBUSCULAR MYCORRHIZAL FUNGI AND RHIZOBIUM ON THE TRIPARTITE ASSOCIATION WITH FIELD PEA (Pisum sativum) AND LENTIL (Lens culinaris) UNDER SASKATCHEWAN FIELD CONDITIONS
… western Canada as a commercial biofertilizer for field crop production. Mycorrhizal inoculant use is an established practice in land reclamation and horticultural activities; however, it is only an emerging interest in agricultural systems. Key questions need to be answered regarding its impact on …

Estimation of the ideal standardized ileal digestible Tryptophan:Lysine ratio in 10 to 20 kg pigs
… to the SID of AA in SBM. The SID of AA in field peas was similar to that of corn, however each were somewhat lower (P < 0.05) than the SID of AA in SBM and CGM. Possibly because of overheating, the SID of AA in HP DDG was lower (P < 0.05) than the other ingredients, especially in Lys. The …

The effect of depth of placement of phosphorus fertiliser on the growth and development of field peas / by Mohammadali H. Derafshi.
… reports on the results of 3 glasshouse and 3 field experiments. The glasshouse experiments measure the effects of depth of placement and level of phosphorus (P) on the growth of field peas (Pisum sativum L. cv. Alma). The results of all the experiments suggest that placing P fertiliser 4-5 cm …

Drivers and Barriers to Producer Adoption of Climate Resilient Pea Varieties in the Western Canadian Prairies
… and drought affect the relative advantage of field pea production, and the severity of these challenges is exacerbated by a changing climate. Advances in crop breeding offer potential solutions in the form of new varieties that address these biotic and environmental stressors, but producer …

Physiological and genetic investigations of iron deficiency in field peas (Pisum sativum L.).
… the long term for all sensitive crops including field peas. The present study was conducted to investigate various aspects of the genetic tolerance of field pea cultivars Santi and Parafield, in particular, with the objective of providing the information to implement an efficient breeding …

Crop Canopy Effects on Kochia Establishment in Crop Fields
… address the issue of resistant kochia in crop fields, we carried out studies to understand the biology of kochia in different crop environments. The goal of this study was to quantify the effect of crop canopies, tillage and residue on kochia germination, survival and seed production in order …

ROTATION EFFECT OF PULSE CROPS ON NITROGEN FIXATION AND CARBON INPUT TO SOIL
… and C input to soil by various pulse crops (chickpea, lentil and field pea) grown in rotation with pulse crops and non-pulse crops. Soil cores from three crop rotations (chickpea-wheat, lentil-wheat and pea-wheat) were collected from Swift Current, SK. Additional soil cores from two rotations …

Belowground Contributions of Pea and Canola to Soil Nitrogen Pools and Processes
… crop grown across the Canadian prairies—namely, field pea and canola, respectively. Using continuous 15N2 labeling, the input of fixed-N to rhizosphere soil from pea plants amounted to less than 2% of the total plant N assimilated via fixation. Nodulation and root 15N enrichment were positively …

Evaluation of X-ray Fluorescence Spectroscopy as a Tool for Element Analysis in Pea Seeds
… XRF for use in element analysis of field pea seeds for quantification of macro- (K and Ca) and micro- (Mn, Fe, Cu, Zn, Se) elements. Pea seed samples were ground into fine flour and pellets were prepared to collect XRF peak intensities. Seventy-three pea seed samples were selected to …

Diversifying crop systems by developing intercropping breeding strategies for improving forage yield and quality in oat-legume mixtures
… (Avena sativa L.) is commonly intercropped with field pea (Pisum sativum L.) to improve forage performance. Despite these advantages, breeding progress for forage mixtures remains slow due to the logistical challenges of evaluating numerous genotype combinations under field conditions. To address …

Examining the effect of rotation sequence on biological nitrogen fixation of pulse crops
… before and after a pulse crop was grown. In the field study, an interaction between site and stubble affected BNF, where pulse crops grown on cereal stubble generally had higher BNF except at Biggar in 2017, and at Davidson and Theodore in 2018; BNF in these pulse crops was higher when grown on …

Evaluation of Yield and Agronomic Performance of Leafed and Semi-leafless Pea Blends
Field pea has two distinct leaf morphologies: leafed (L) and semi-leafless (SL). The leafed pea is more susceptible to lodging, but it may have high yield potential when lodging is prevented. In contrast, the semi-leafless pea is bred for lodging resistance and has greater yield stability. However, …
