Seed coat breakage of field pea (Pisum sativum L.) during harvesting and handling increases dockage and reduces seed quality. A laboratory-scale abrasive dehulling device was used to evaluate seed coat durability of field peas grown in 1983 (20 cultivars, 6 locations) and 1984 (17 cultivars, 5 locations). Analysis of variance revealed significant (P < 0.05) effects due to cultivar and location of growth for both years. Mean cultivar seed coat breakage ranged from 1.5 to 22.3% in 1983 and from 0.6 to 14.9% in 1984. The seed coat breakage of several cultivars in 1983 (MP 913, Line 32, Tipu, MP 926 and MP 942) and 1984 (MP 939 and Sv20565) was greater (P < 0.05) than that of Century, the current standard in the industry. The seed coat breakage of Bellevue was less (P < 0.05) than that of Century in both years. Locations which experienced hot or dry fall conditions produced seed with poor seed coat durability. Broad sense heritability of seed coat durability, based on the components of variance method, was 57.5 and 56.2% in 1983 and 1984, respectively. Seed coat breakage was not correlated (P > 0.05) with seed coat content or thickness, protein, lignin, neutral detergent fiber, hemicellulose content, 1000-seed weight or strength of adhesion between the cotyledons. Cellulose content of the seed coat was negatively correlated (r = −0.77, P < 0.05) with seed coat breakage in 1984, but not in 1983 (P > 0.05).Key words: Pea, Pisum sativum L., seed coat durability

Effect On Yield

Seed lots of field pea (Pisum sativum L.), varying in cooking quality (viscosity of puree) and protein concentration were grown in the field in 1986 and 1987 to determine the effect of those factors on subsequent yield, cooking quality and protein concentration. Under the conditions of the experiments, cooking quality and protein concentration of the seed had no marked effect on yield, 1000-seed weight, cooking quality or protein concentration of the subsequent crop.

Cultivar Description

Bellevue field pea (Pisum sativum L.) was licensed in 1986. It is about 15% higher yielding than the check cultivars Century and Trapper. Bellevue has smooth seeds with yellow cotyledons. It has the le gene for shortened internodes and is about 6 d later maturing than Century and Trapper. Seed weight is about 179 g/1000 seeds, intermediate between Century and Trapper.Key words: Cultivar description, pea (field), Pisum sativum L.

Proximate And Mineral Composition

Field pea seeds from 10 cultivars grown at two locations in Manitoba in 1986 and 1987 were analyzed for proximate and mineral profiles. Cultivars differed significantly in their level of total protein, crude fat, ADF, and all minerals tested. However, differences were not extremely large and were comparable to European reports. Location-year also had a significant effect on the levels of total protein, ADF, and all minerals tested. In most cases, the warmest location-year produced relatively higher levels of minerals, ash, and total protein, and lower seed yield than the coolest location-year.

Weather Parameters

Background: Field pea, Pisum sativum L. is an important winter-season pulse crop. It is subjected to damage by both field and storage insect pests and approximately 10-15 per cent reduction in yield was reported due to the infestation of different insect pests. Among these, pulse aphid (Aphis craccivora Koch.) affects plant physiology directly by removal of nutrients or indirectly by dispersal of various viral diseases. The present investigation has been aimed to study the seasonal fluctuations of aphids and their natural enemies as well as their correlation. Another objective was to know the effect of various weather parameters on pulse aphids and their natural enemies which ultimately would be helpful to develop a forewarning model.Methods: The field experiment was conducted at the A-B Block Farm of Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal using two varieties of field pea (KPMR 935 and IFPD 122) during rabi seasons of two consecutive years of 2017-18 and 2018-19 following a Randomized Block Design with three replications. After recording the total population of both pests (nymphs and adults) and their natural enemies across the season, the mean population was worked out and used for correlation and regression studies along with the weather parameters. Result: Maximum aphid population was noticed during the peak pod formation stage of the crop irrespective of the varieties. The pest population was very strongly correlated with the incidence of coccinellid and ant population in both test varieties. Among the weather parameters, both maximum and minimum temperature and sunshine hour showed a positive correlation with the pest population and their natural enemies but relative humidity and rainfall showed a negative correlation. Regression studies indicated that temperature and relative humidity were the most influencing factors over the incidence of aphid in both the seasons.
