Impact of some soil organic improvements on soil fertility and plant growth on cucumber plant (cucumis sativus)‎ under greenhouse condition in Sulaimaniyah governorate

Abstract EN

For this goal, four types of soil improvements were used (Industrial biological fertilizer, such as dry yeast (Saccharomyces cerevisiae) in three concentrations (3, 6, 9 g-L), Biofertilisers with one concentration, organic matter, such as humic acid and folic acid with one concentrations as well as control.

These seven applications were administered to Cucumber plant in an R.

design with three different replicationsThe outcomes show that when use the results show that using dry yeast (6 g-L) has a significant difference in (P0.05) on the soil PH that decreased to 6.8 as well as Nitrogen contain 4.8% ; available phosphorus 40.5ppm; potassium 2.9ppm.

Humic acid has a statistically significant (P0.05) influence on EC, P, O.

, Biofertilisers have a statistically significant effect (P0.05) on Ca (22.04ppm) soluble, Folic acid made a significant (P0.05) effect on soils E.

C.

( 0.73ds-m), A comparison between effects of the treatments on cucumber yield and number of days until harvesting, green group system, root group system, and TSS (total soluble solid) it become clear that Yeast 3g-L give the significant difference (P0.05), treatments Humic acid, Biofertilisers, Yeast 3g-L give a significant difference (P0.05) on green group system and root group system.
