Abstract

An experiment was conducted within (R. C. B. D.) design with three blocks,at the experimental field design with three blocks, at the experimental field of agric. college of Al-Anbar univ., during 2002 / 2003 and 2003 / 2004 to study the effect of concentrations of Al-Nahrain solution on growth and yield of pea Pisum sativum L. Enword Cv., the seeds were socked for one hour presewing in several concentrations of Al-Nahrain solution (control, 5m1 / L, 10m1 / L, 15m1 / L).
The results showed that the concentration of 5ml / L was superior in germination percentage (76.6 & 85.4) %, germination rate (12.4 & 11.7) day, plant length (65.5 & 60.8) cm, leaf area (124.4 & 91.2) cm2, plnat yield (0.90 & 0.80) kg and total yield (1.1 & 1.0) ton / d, as compared with concentration 15ml / L (62.3 & 68.2) %, (13.4 & 13.0) day, (55.0 & 50.1) cm, (79.4 & 71.4) cm2, (0.61 & 0.55) kg and (0.77 & 0.64) ton / d for both seasons respectively, Also,the concentration of 5ml / L was superior in dry matter percentage/plant (41.7 & 42.0) % branch number / plant (3.4 & 3.8) and bod length (7.9 & 7.5) cm as compared with control (34.8 & 32.7) %, (1.8 & 2.2) branch and (6.7 & 6.3) cm for both seasons respectively. While concentration of 10ml / L was superior in bod wet weight (4.6 & 4.5) gm as compared with control (3.3 & 3.5) gm for both seasons respectively.
