Response of some pea cultivars to supplementary irrigation under rainfall conditions [electronic resource].

Includes references.

The productivity of pea was determined under calcareous soil and rainfall conditions at El-Hammam region in Nort.lJ Western Coastal Zone (NWCZ) of Egypt. Treatments of supplementary irrigation and bacterial inoculation were applied to improve yield for two cultivars (Lincolin and Mastar B) of pea plants. To achieve the goal of study, the experiment was conducted through two growing seasons i.e. 2005/2006 and 2006/2007. The treatments were the combination between 4 treatments as supplementary irrigation i.e. rainfall, rainfall + 60 mm/fed, rainfall + 90 mm/fed and rainfall +120 mm/fed and 2 inoculation treatments (Rhizobium and Phosphorus dissolving bacteria P.D.B.) or without inoculation, which were applied on two cultivars of pea. Growth characters and yield and its components as well as chemical compositions of pea were determined. The results were summarized as follows:- 1- Rainfall + 120 mm supplementary irrigation treatment led to obtain the maximum significant values for all characteristics under study: plant height, number of leaves and branches per plant, fresh and dry weight per plant, except dry matter percentage which gave the highest value with rainfall treatment. Also, yield and its components (number of pods per plant, pod length, fresh weight of pod, 100 seeds weight, pods yield /plant and per fed.), were increased significantly with increasing the rate of supplementary irrigation. The content of nitrogen, phosphorus, potassium, protein and carbohydrates in pea seeds, showed the same previous trend. 2- Master B cultivar exceeded Lincolin cultivar for all the characteristics under study.
