IMPACT OF SOME TREATMENTS ON GROWTH AND YIELDING OF PEA PLANTS GROWN UNDER SALINE RECLAIMED SOIL CONDITIONS
The possibility of improving growth and yielding of pea plants grown under reclaimed soil conditions which having salinity level of about 5000 ppm was investigated in a private Farm, Fayoum, Egypt, during the two successive seasons of 2007/2008 and 2008/2009. For achievement this aim, the calcium paste treated-seeds of pea were sown in beds fecundated with ground sunflower heads. The producing pea plants were sprayed with ascorbic acid at the rates of 0, 100, 200,300 and 400 mgL-1. Significant positive influences of calcium paste plus ground sunflower heads applied alone or in combination with all ascorbic acid treatments used under this study were observed on growth, yield of green pods and seeds as well as the tested chemical constituents. In comparison with untreated seeds sown in non-fecundated beds, the plants producing from the calcium paste treated-seeds sown in beds fecundated with ground sunflower heads represented significant increases in growth traits (i.e. plant height, No. of branches plant-1 and shoot dry weight plant-1) and green pods yield and its components (i.e. No. of green pods plant-1, pod weight and green pods yield feddan-1) as well as green seeds yield and its components (i.e. No. of green seeds pod-1, 100-seed weight and green seeds yield feddan-1). In addition, the concentrations of some chemical constituents (i.e. total chlorophyll, total carotenoids, ascorbic acid, free proline, total soluble sugars, total phenols, N, P, K, Ca, Ca/Na ratio, Fe, Mn and Zn in shoots of plants besides, starch%and protein% were increased with the shortage in total soluble sugars% in green seeds). As for ascorbic acid foliar application, plants sprayed at all studied rates (i.e. 100, 200, 300 and 400 mgL-1) revealed significant increases in all investigated parameters (i.e. growth traits, green pods and seeds yields and their components as well as chemical constituents of plant shoots and green seeds) as compared with untreated plants. Ascorbic acid treatment at the rate of 300 mgL-1 combined with calcium paste treated-seeds sown in beds fecundated with ground sunflower heads proved to be the best and may counteracted the inhibitory effects of salinity on pea plants.
In view of above mentioned results, it has been concluded that spraying pea plants "cv. Master-B", producing from calcium paste treated-seeds sown in beds fecundated with ground sunflower heads, with ascorbic acid at the rate of 300 mgL-1 could be counteracted the adverse conditions particularly, salinity up to 5000 ppm and consequently, economic green pods and seeds yield is obtainable.
