Study Effect Different Concentrations of Calcium Sulfate And Boric Acid And Their Interactions on Some Physiological Characteristices of Vigna Ungiculata L. Plant

Abstract

      This experiment was conducating during the season 2023 – 2024 by using the pots in plant garden of agricultural collageto study the effect of foliar spray with calcium sulfat  ( 50 , 100 , 150 )Mg . L.^-1 and boric acid (50 ,100) Mg L.^-1 on some physiological characteristics of cowpea plant , The resuits showed signi ficants increase in plant content of H₂0reach to (4.45)Mo/g fresh wight and proline reach (22.13)Mg/gby treatment with 150 Mg L^-1 .of CaSo₄ to protect the plant from stress while there was significants decrease  in catalase enzyme activity reach (30.14)Abs.unitand Salicylic acid content reach (2.36)Mg/mand vitamin Ereach (0.498)Mg/ginsame concentration , also the resuts showed there was signi Ficant increase in plant content of salicy liy acidreach(4.11)Mg/m and prolinereach(24.60)Mg/g fresh weightat the concentration of 100Mg.L¹ of boric acid while there was signiRicant decrease in cata lase enzyme activity reach (31.01)Abs.unitand plant content of Hydrogen peroxide reach(2.23)Mo/g fresh weightandvitamine E reach (0.467)Mg/gat same concentration also there was significant effect between experimentfactors on most of study traitexeptplant content of salicylic acidthis showed effect of CaSo₄ and boric acid on enzymatic and non – enzymatic plant content to protect cellular component and vital functions of plant this reflects positively on plant growth .
