The 1960S

The grain yield of field pea (Pisum sativum L.) between 1959-60 and 1991-92 was examined in selected Hundreds in important peagrowing regions of South Australia. Over the 33 years, the rates of increase in grain yield have been substantial, ranging from 20 to 48 kg/ha.year. The rate of increase in the State average for the same period was 22 kg/ha. year. The largest rates of increase have occurred mainly in the Hundreds in the higher rainfall areas. Yields have increased irregularly. During the 1960s grain yields rose relatively slowly, but from the mid 1970s to the mid 1980s, large increases occurred. Since then, yields have increased relatively little or, in some Hundreds, declined. With one exception, grain yield was positively and significantly correlated with seasonal (April-October) rainfall in each Hundred, but there were few significant correlations with rainfall in individual months. Yield was often correlated with winter and autumn rainfall but not with spring rainfall. The efficiencies of seasonal water use in the Hundreds ranged from 2.7 to 4.8 kg/ha.mm; these were lower than the maximum values recorded for other winter grain legumes, suggesting that water use efficiencies can improve substantially.

Clustering Pattern

The experimental material consisting of forty advance genotypes including two checks (Rachna and Shikha) was evaluated in Randomized Block Design with three replications for eleven characters by using Mahalanobis’s D2 statistic. The clustering pattern of genotypes showed no definite relationship between genetic divergence and geographical distribution of genotypes. The genotypes were grouped into seven clusters. The maximum ten lines were put cluster IV, it had maximum intra-cluster distance while inter-cluster distance was highest between I and II. Cluster means indicated that none of the clusters was superior for all the characters studies; however hybridization between genotypes belonging to different cluster (viz. Ist and IInd) is suggested for development of superior genotypes in field pea.

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.
