Filed experiment was conducted to test the effect of saline water and potassium fertilizers rate on proline and water potential of Pisum sativum L. (Var.Senador Cambados ) leaves . Treatments of the experiment included two levels of water salinity( 2, 7 dSm-1) as a main plot and fertilizer rates as a sub plot. Results indicated that irrigation of plant with saline water 7 dSm-1 and fertilization 150 kg/donum increased proline accumulation and water potential 0.31 mmol/g,-17.00 bar at 9 AM morning and 0.62 mmol/g , -21.00 bar at 3 PM afternoon ,Irrigating plant with a 2 dSm-1 and fertilization 300 kg/donum decreased proline accumulation and water potential of leaves 0.22 mmol/g, -16.00 bar at 9 AM and 0.43 mmol/g,-18.00 bar at 3 PM . Irrigation plants with saline water 7 dSm-1 and fertilizer with 150 kg/ Donum K2SO4 increased Root/Shoot to 0.89 ,while 0.41 after irrigation with 2 dSm-1 saline water and fertilization with 300 kg/ Donum K2SO4 . The Na/K ratio increased to 0.53 under 7 dSm-1 of irrigation water and 150 kg/Donum fertilization and decreased to 0.1 under 2 dSm-1 irrigation water and fertilized 300 kg/ Donum . The results lead to the conclusion that potassium fertilization may reduce the inhibitory effect of increasing salinity of irrigation water on pea.

High rates of phosphorus (P) banded with or near the seed did not consistently improve seed yield or cooking quality of yellow field pea (Pisum sativum L. ’Century’) in soils initially moderate to high in P. Triple superphosphate applied at 50 kg ha−1 P2O5 with the seed, in rows spaced 30 cm apart, resulted in small decreases in seedling stands, but generally did not reduce yields.Key words: Field pea (Pisum sativum L.), seeding date, nitrogen, phosphorus, fertilizer placement, cooking quality

Study Results

Field experiment was conducted to test the effect of saline water 2 and7 dSm-1 potassium fertilizer rate 150,300 and 450 kg/donum on nitrogen fixation in Pisum sativum L. nodules. The experiment included anatomy study .Results water salinity ( 2,7 dSm-1) as a main plot and fertilizer rates as a sub plot. Results indicated that irrigation with saline water 7 dSm-¹ caused a significant decrease in N contents especially in the lower parts of the plants. The percentage of the N decreased in lower leaves to (0.01%) under 7dSm-¹ and 300 kg/donum fertilizer; however the percentage increased in the upper leaves to (2.80%) under with 2dSm-¹of irrigation water and 300 kg/ donum fertilizer rate. Fresh weight decreased to 6.26g under 7 dSm-¹ and 450 kg/donum fertilizer rate, but irrigated with 2 dSm-¹ and 300 kg/donum fertilizer rate increased it to 18.87g. The nodules number , fresh and dry weight decreased to( 114 nodule/plant ,2.18 and 1.70 g/plant ) with 7 dSm-¹ salinity water and 150 kg/donum fertilizer, respectively , the results showed that irrigation with 2 dSm-¹ saline water and 300kg/ donum fertilizer increased them to ( 167.6 nodule/plant,5.43 and 2.20 g/plant )respectively. Increasing levels of irrigation water from 2 to 7 dSm-¹ salinity, caused increased vessels thickness in both leaves and root; this is because the salt accumulated on cell wall .whereas cortex cell wall was thicker in root for same reason . Thus of nitrogen fixing symbiosis in pea was more determined with anatomy change in root tissues which caused decreasing in nodules number fresh and dry weight. Accordingly, conclusion could be made that potassium may reduce the inhibitory effect for nitrogen fixation in saline water irrigation condition.

Salinity Water

Field experiment was conducted to test the effect of saline water and fertilizers rate on Pisum sativum L. plants . Treatments of the experiment included two levels of water salinity (2, 7 dSm-1) as a main plot and three levels of potash fertilization K2SO4 (44%K) namely 150 control, 300 and 450 kg/Donum as a sub plot. Results indicated that irrigation of plant with saline water 7 dSm-¹ caused a significant decrease in K and P contents specially in the upper parts of the plants , the percentage of the K increased (2.80%) under 2 dSm-¹of irrigation water and 300 kg/ donum fertilizer rate in the upper leaves, However K decreased(1.10%) in lower leaves under 7 dSm-¹ and 300 kg/donum fertilizer. while P increased in pods under same water salinity but with 150kg/ donum potash fertilizer. although P decreased( 0. 3 %) in pods under 7 dSm-¹ salinity water with 150 kg/donum fertilizer. However the results showed irrigation with 7 dSm-¹ saline water and 150kg/ donum fertilizer increased Ca, Mg and Na percentage ( 3.1 ,0.45 ,1.19 % ) in the roots of plants respectively , the lowest Ca ,Mg percentage was in pods of plants irrigated with 7 dSm-¹ saline water and fertilized with 150kg/ donum (0.39,0.05%), beside Na lowest percentage was ( 0.16 %) in upper leaves after using 2 dSm-¹ saline water and fertilized with 300kg/ donum. Accordingly, conclusion could be made that potassium fertilization may reduce the inhibitory effect of increasing salinity of irrigation water on pea.
