“…2019 (Sidney) with ‘Nette 2010’ yellow field pea seed from PULSE USA (https://www.pulseusa.com/seed). Seeding rate of FP targeted 77 pure live seed (PLS) m −2 for all site‐years, following previously recommended seeding rates for the region (Koeshall et al., 2020; Stepanovic et al., 2018). The FP was seeded with a SRES experimental plot planter (https://kincaidseedresearch.com/equipment/planters-drills/) with a row spacing of 24 cm and eight total row units.…”

Integration of field pea (Pisum sativum L.) (FP) into dryland cropping systems has increased due to ecological and economic benefits, paired with a growing market for pea-derived products. Challenges exist in the High Plains that limit the integration of crop rotations to replace fallow periods with FP in wheat (Triticum aestivum L.)based systems. This experiment compares chemical summer fallow to FP in a fallowwheat rotation at two locations in western Nebraska. Soil water content, soil fertility, N mineralization, FP yield, and subsequent hard red winter wheat (HWW) yields were recorded. Subsequent HWW yields were not different between crop sequences (P = .42). The interaction of site-year with crop sequence explained the HWW yield differences (P = .0005), mostly due to precipitation variability among site-years. Most soil parameters tested only showed a main effect of date due to temporal changes in soil nutrient cycling. Replacing summer fallow with FP resulted in reduced soil water content, however, that did not result in long-term moisture deficiency due to crop sequence type. System annualized gross revenue was equal to or greater for 2 site-years for FP compared with fallow, with an average increase of US$113.15 ha -1 . Pea-wheat reduced annualized net losses in 1 site-year by $70 ha -1 compared with fallow-wheat in the "average" pricing model. Among 3 site-years and three pricing models, pea-wheat resulted in greater net profit or reduced net losses compared with fallow-wheat in 5 site-year comparisons.

Montana is the leading producer of field peas (Pisum sativum L.) in the United States. A density of 8 to 10 plants ft−2 is recommended when growing field peas in that state, but this recommendation is based on work done elsewhere. Field experiments were conducted in central Montana from 2021 through 2023 and at three additional locations in the final year to determine the yield and the economically optimum plant population (EOPP) when growing field peas for grain. The semi‐leafless, yellow‐cotyledon variety Montech 4152 was planted at five rates (5, 7, 9, 11, and 13 pure live seed [PLS] ft−2) in all 3 years with two additional rates (3 and 15 PLS ft−2) added in the final year. A minimum plant density of 6 to 8 plants ft−2, or planting field pea at 7 to 9 PLS ft−2, produced a grain yield comparable to or greater than amounts produced at other seeding rates. The minimum EOPP across the six experiments ranged from 3 (2.8) to 7 (6.4) plants ft−2, corresponding to a seeding rate of 3 to 7 PLS ft−2. However, more weeds were observed when field pea was planted at 3 PLS ft−2 than at higher rates in one of the experiments. A field pea density of 6 to 8 plants ft−2 is sufficient to optimize grain yield and economic returns in Montana and similar dryland environments.

The inclusion of pulse crops in Canadian rotations has the potential to improve cropping system efficiencies, reduce the overall amount of applied nitrogen, provide economic opportunities for producers, and reduce the overall carbon footprint of the cropping system. Although primarily grown in western Canada, many pulse species – field pea in particular, are well suited to temperate growing conditions in the Maritime region of Canada. A study was conducted over two years at Harrington, Prince Edward Island, and consisted of four field pea varieties including of two yellow varieties (AAC Lacombe and CDC Saffron) and two green varieties (CDC Limerick and CDC Raezer) were planted at three plant population densities - 75, 100 and 125 plants m-2. The study also measured the effects of nitrogen fertilizer applied pre-plant (0 vs. 15 kg ha-1) and applied plant available sulfur (0 vs. 25 kg ha-1). Overall, yellow pea varieties were higher yielding than green pea varieties, and there was a linear increase in yield with increased seeding rate. There were no significant effects of pre-plant nitrogen fertilizer on yield, although it did slightly increase seed protein. Applied sulfur had a positive effect on yield and a slightly negative effect on thousand seed weight. This experiment provides a recommendation for the optimal seeding rate (100 plants m-2) and fertility recommendations to achieve profitable yields growing field pea in the Maritime region of Canada.
