Abstract. The object of this study is knowing the effect of tea black waste and Disper vital compound on the Chemical qualities, the growth and the yield For (of)  Zea mays L. In the spring of 2022 , an agricultural experiment was conducted in Kerbala , Alhindia city . Three replications , two factors , and a randomized complete block design ( RCBD ) were used to build up the factorial experiment. The first factor was Disper vital compound spraying ( control , 1.56 2.87 gm L¹ ), the second factor was black tea mixed with soil ( control , 20 , 30 , 40 gm L ' ) . The medicines were administered in two dosages , and after monitoring all growth indicators , the plants were harvested when fully mature . The results refer to the impact of the black tea wastes when mixed with soil of higher significance in increase the NH , N , Na , mg , Ca , Cl and ph of soil from 27.73 mg.kg , 29.23 , 2.78 , 4.87 , 5.91 mm.L¹ 7.99 in control to 29.23 mg kg 3.89 , 3.92 , 5.95 , 6.87 mm L. and 7.36 in treatment ( 40gm / kg ) respectively , as well the black tea wastes of higher significance in increase Zinc , protean , oil percentage and grain yield and Weight of 1000 in treatment ( 40gm / kg ) , As for spraying with Disper vital compound It has a significant effect in increasing the proportion of both Zinc , protean , oil grain yield and Weight of 1000 in treatment ( 2.87 gm L ) .

A pot assay on the plastic container of the wire sunshade in the University of Kerbala's Agricultural Division was conducted to research the impact of potassium treatment, the salinity of irrigation water and ascobin sprinkling, just as their connections, on the some plant hormones activities (auxin, gibberellin and abscisic acid) in developing Zea mays crops in a soil with sandy texture during the farming fall period of 2017-2018. The trial was planned as a factorial one with three factors, Potassium adding are 0, 100 and 200 Kg K.ha-1. the irrigation water salinity are 1, 3 and 6 ds.m-1 ; and the third factor incorporates foliar application with 0, 300 and 600 mg.L-1 ascobin (ascorbic acid + citric acid 2:1) at two phases: the main stage at 6 leaves and 21 days after germination and the second stage at 12 leaves and 70 days after germination. This test included 81 exploratory units dependent on a complete randomized design (CRD) with three recreates. The outcomes show that variables engaged with this experiment and their associations significantly affect the some plant hormones activities , which increment when the foliar ascobin application focus increment. The outcomes likewise show the chance of utilizing saline water for Zea mays irrigation when the foliar ascobin and potassium are adding .
