Effect of molybdenum and nitrogen on Phaseolus vulgaris L., Cicer arietinum L. and Lens culinaris M. seedlings grown under salt stress

Abstract

The leguminous constitute an important food diet component especially in developing countries, they represent 90% of the global consumption, and they are very rich in proteins and relatively adapted to the Mediterranean climate. Soil nutrient deficiencies and salinity are the main factors which reduce plant production in the semiarid and arid areas around the world. The plant material used is composed by three species from Fabaceae; Phaseolus vulgaris L., Cicer arietinum L. and Lens culinaris M. seedlings that were grown in pots under different concentrations of NaCl (3 g/l, 6 g/l, 9 g/l), molybdenum (0,2 ppm) added as ammonium molybdate and nitrogen added as potassium nitrate (0,02 g/l). The fresh shoot, chlorophyll content and nitrate reductase activity were analyzed in order to estimate the effect of molybdenum (Mo) and nitrogen (N) on salt stressed plants. The effect of both molybdenum and nitrogen on lentil has not been well studied and especially for Algerian legumes This work shows the importance of molybdenum and nitrogen added to irrigation water to avoid the negative effect of sodium chloride and to enhance legume species tolerance to salt stress.

Role of Micronutrients in Providing Abiotic Stress Tolerance

“…The supplementation of Mo also improved the cold tolerance in cauliflower seeds (Rihan et al 2014) and in wheat (Al-Issawi et al 2016). The application of Mo reduced the salt stress in Phaseolus vulgaris L., Cicer arietinum L. and Lens culinaris M. by enhancing the seedling growth, development, nitrogen metabolism and yield attributes (Salha and Chaabane 2016).…”
