THE EFFECT OF SALICYLIC ACID, FERTILIZER NPKZn AND WATER STRESS ON THE PEPPER PLANT, CAPSICUM ANNUUM L.

An experience blastic pots of 8 kg capacity in the agricultural season of 2016-2017 was carried out in the green house of Department of Biology, College of Education for Pure Science, Ibn AL-Haitham, Baghdad University. The aim of this experiment is to study the effect of NPKZn fertilizer at 160 kg and salicylic acid with concentrations (20, 30 mg.L-1). In addition to the treatment of control of both factors and their interactions under the effect of water stress (irrigation every day and every 6 days and every 12 days) in some qualities [chlorophyll content and the effectiveness enzyme of (SOD, CAT, POD) (unit mg protein(-1)) and proline content (mu g dry weight-1)) in the pepper shoot. The design experiment was design of sectors for full randomisation (RCBD) and three replications, the results confirmed that the water stress was significantly increased all studied traits except recipe chlorophyll content has been reduced, fertilization and spraying salicylic acid and reduced their interaction moral qualities of all except chlorophyll content rose compared with the control treatment.
