Considerable work has been done on the root nodules and leg-haemoglobin contents of different leguminous plants (Wilson, 1970; Singh et al, 1973; Balsubramanian and Sinha, 1976a, b; Kumar and Garg, 1980; Batra and Bhardwaj, 1981; Gupta and Varshney, 1999).In the present study, an effort has been made to assess the effect of soil salinity on The Short the growth and leg-haemoglobin content of nodules in two varieties of field pea (Pisum sativum Linn.).The study was conducted in soil beds (size 1 m2) under natural conditions, in Botanical garden of Gangasheel Mahavidyalaya, Faijullapur, Nawabganj, Bareilly (U.

P.).Three replicates were taken Tank Tops for each treatment (control EC 8 CE 8) of both varieties (Var.Pant pea 42 and Pant pea-66).

The seeds were sown with gap of equal distance (1 ft.) in soil bed.The result indicates that variety Pant pea-42 is more salt tolerant than Pant pea-66.The number and size of nodules decrease with increase in salinity level in both varieties at all stages of growth (leafy, flowering and maturity).

Leg-haemoglobin decreases with the increase level of soil salinity.This study concludes that soil salinity decreases the number of nodules, size of nodules and leg-haemoglobin contents of Field pea (Pisum sativum Linn.).
