The experiment was conducted during the winter season of 2017-2018 and 2018-2019 at directorates of agriculture in Al-Zubair district, Basrah, Iraq to study the effect of sodium nitroprusside (SNP) at four concentration (0, 50, 100 and 150) ?M with number of sprays (once and twice) and three cultivars (Pruktor F1, Luna and Rain ball F1) on mineral content of Nitrogen (N), Phosphorous (P), Potassium (K), Sodium (Na), Potassium/Sodium (K+/Na+) ratio, Chloride (Cl-), Sulfur (S) and Iron (Fe) of leaves. Split-Split Plot design was used with three replicates per treatment. The means of treatments were compared by L.S.D. at 0.05 probability. Results indicated that Pruktor F1 had the highest percentage of N, P, K, K+/Na+ ratio for both growing seasons while the highest accumulation of Na and Cl- in Rain ball F1 cultivar. Plants sprayed twice with SNP had a significant increase in P, K, K+/Na+ ratio, S, and Fe comparing with once spray for both growing seasons. PruktorF1 sprayed with SNP at 100 ?M twice time was superior in P, K, K+/Na+ ratio, S and Fe, whereas, the same cultivar at 150 ?M concentration was superior in N for both growing seasons, same cultivar at 100 and 150 ?M sprayed twice time gave the lowest percentage of Na+ and Cl–, respectively. Also Rain ball F1 at control treatment had the highest accumulation of Na and of Cl-.

ABSTRACT Variations in plasma renin activity and urinary aldosterone excretion were studied in normal subjects submitted to salt restriction and simultaneous inhibition of ACTH production with a new synthetic steroid, 6-dehydro-16-methylene hydrocortisone (STC 407). At a dose of 10 mg t. i. d. this preparation exerts an inhibitory effect on the pituitary comparable to that of 2 mg of dexamethasone. In subjects maintained on a restricted salt intake, STC 407 does not delay the establishment of an equilibrium in sodium balance. The increases in endogenous aldosterone production and in plasma renin activity are also similar to those seen in the control subjects. A possible mineralocorticoid effect of STC 407 can be excluded. Under identical experimental conditions, the administration of dexamethasone yielded results comparable to those obtained with STC 407.

Abstract A laboratory experiment regarding germination and seedling growth test was conducted with three black gram genotypes tested under three salinity levels (0, 75 and 150 mM), for 10 days, in sand culture within small plastic pot, to investigate the germination and seedling growth characteristics. Different germination traits of all black gram genotypes, like germination percentage (GP), germination rate (GR), coefficient of velocity of germination (CVG) greatly reduced, as well as mean germination time (MGT) increased with increasing salt stress. At high salt stress, BARI Mash-3 provided the highest GP reduction (28.58%), while the lowest was recorded (15.79% to control) in BARI Mash-1. Salinity have the negative impact on shoot and root lengths, fresh and dry weights. The highest (50.32% to control) and lowest reduction (36.39%) of shoot length were recorded in BARI Mash-2 and BARI Mash-1, respectively, under 150 mM NaCl saline conditions. There were significant reduction of root lengths, root fresh and dry weight, shoot length, shoot fresh and dry weight in all genotypes under saline condition. The genotypes were arranged as BARI Mash-1 > BARI Mash-3 > BARI Mash-2, with respect to salinity tolerance.
