Effect of foliar spray of potassium and zinc on qualitative qualities of okra seeds

الملخص EN

A field experiment was carried out at the College of Agriculture / University of Baghdad to study the effect of spraying different concentrations of potassium sulphate 44%K as a source of potassium element in four concentrations (0,2000,4000,6000) mg K.l-1 and refer to them K0, K1, K2 and K3 respectively and zinc sulphate 22% Zn as a source of zinc element in three concentrations (0, 30, 60) mg Zn.l-1 and refer to them Zn0, Zn1 and Zn2 respectively for the spring season 2017.

Split plot experiment in Randomized Complete Block Design (RCBD) with three replicates was adapted where potassium factor represented main plot and zinc factor in sub-plot .The means were compared at least significant difference (L.S.D) at 0.05 probability level.

Resulted showed that spraying of potassium K3 significantly increased germination percentage to 92.22%, speed germination to 10.28 day, Specific gravity to 98.09 seed.5g-1 , oil percentage to 21.82%, carbohydrate percentage to 33.98% protein percentage to 22.01%.

While Zn2 significantly increased germination percentage to 90.67%.

Speed germination to 9.99 day, Specific gravity to 97.93 seed.5g-1 , oil percentage to 20.66%, carbohydrate percentage to 33.42% protein percentage to 21.70% compare to control.
