EFFECT OF KINETIN IN GROWTH PEPPER IRRIGATED WITH DIFFERENT SALINE WATER
AbstractA Plastic pot experiment was conducted in agreenhouse conditions during the autumn season to study the effect of kinetin in the growth of capsicum which irrigated by different saline water type (syzar).The study included two factors:the first was salinity of Irrigation water in four levels (1.1,2,4 and 6) dS m-1 have the symbbl (S0,S1,S2 and S3) respectively and the second factor was spray with growth regular (kinetin) on plant with four levels (0,50,100 and 150) mg L-1. The results refers to: Decrease of plant high, one plant yield, Phosphoeous and potassium coucent ration in shoot part from 33.39 cm,35.27 g plant-1,4.9 g kg-1,19.6 g kg-1 respectively at control treatment to 23.21 cm, 24.53 g plant-1, 3.2 g kg-1, 17.4 g.kg-1 respectively. While nitrogen conceutration in shoot part was increased from 13.3 g kg-1 at control treatment to 17.7 at highest level of salilinty Irrigation water. The spray with rinetin at the level 100 mg L-1 achieved highest results in plant high, one plant yield, Phosphorous concentration in shoot part 31.40 cm, 35.21 gm plant-1,4.3 g kg-1 respectively compard to that of control 25.64 cm, 27.80 gm plant-1,3.8 g kg-1 respectively, while spray with 150 mg L-1 achieved high rest valve for Phosphorous and potisum concentration in shoot part 16.2 and 18,7 g kg-1 compared with control treatment 14.6 and 18.2 g kg-1. The interaction between stady factor was significant and the high value of the most characteristics was achieved by spray with 100 mg L-1 from kinetin and Irrigated with 1.1 dS.m-1 water, This treatment gave 37.27 cm, 41.17 gm plant-1 5.0 g kg-1, 19.7 g kg-1 for plant high, one plant yield, Phosphorous and potassium concentration compared with out addition kinetin and irrigation with 6 dS m-1 saline water 18.80 cm , 20.68 g plant-1, 2.9 g kg-1, 17.1 g kg-1 respectively.
