Effect of Organic Additives of Okra Cultivated in Unheated Greenhouses on Certain Fruit Characteristics

Abstract EN

The experiment conducted during the winter season 2017-2018 in one of the unheated greenhouse in the Research Station of the Faculty of Agriculture collage - All Muthanna University in the south of Iraq in All Samawah city, in order to study the "Effect of addition cows fertilizer, Water hyacinth compost and spray nanoparticle algae minutes and there impact on some qualities of okra fruits (Hasnawiya cultivar)".

The experiment was contain (27) factor treatments and separated in possible combinations among three levels of bovine fertilizer (0, 2, 4) kg/m2 and three levels of Water hyacinth compost (0, 2, 4) kg/m2 and three concentrations of Organic fertilizer for marine algae nanoparticles extract (0, 0.75, 1.5) ml/L.

The statistical design is split-split plot design and the experiment performed twice for three randomized sections and compared to the averages of the coefficients using the least significant difference test at the probability level (0.05).

The main results are summarized as follows.1.

The addition of bovine fertilizers in the levels of (2, 4) kg/m2 the Significant increase in the percentage of total soluble solids for fruits, by an increase of (8.64, 7.08% ) and dry matter of fruits by an increase (6.04, 9.78)% .

Significant increase in fiber content (0.56 and 0.95% ) compared to the comparison treatment, respectively, while the level of 4 kg/m2 achieved significant increase in fruit content in vitamin C compared to the comparison treatment and an increase of 5.16% .2.

Levels (2, 4) kg/m2 Significant increase in percentage of total dissolved solids Vitamin C increased by 24.85, 42.23% by 20.02 and 27.00% by the percentage of dry matter and by 9.91 and 12.81% , which led to a significant decrease in fiber percentage by 6.28 and 11.78% Comparative treatment, respectively.3.

Spraying with nanoparticle algae minutes in two concentrations (0.75 and 1.5) ml/l significantly increased the percentage of total dissolved solids by (27.13, 53.87)% and in the amount of vitamin C by (24.05 and 50.01% ) and in percentage.

The dry matter of the fruit increased by 5.90 and 12.36% , which resulted in a significant decrease in the percentage of fiber by 3.74 and 1.85% compared to the comparison treatment, respectively.4.

Some bilateral and triple interference showed significant effect in some studied traits.
