Effect of Soil Salinity on the Nodulation and Leghaemoglobin in two Variables of (Pisum sativum L)

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 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 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.).
