Study the Effect of Tea Black Waste and Disper Vital Compound on the Chemical Qualities, and Growth Yield of Zea Mays L.

Abstract

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 ) .
