Effect of different mulching materials on the yield of cucumber (Cucumis Sativus L.)

Magistritöö Aianduse õppekavalHarilik kurk on erinevalt paljudest teistest köögiviljadest soojanõudlikum kultuur. Eestis ei anna harilik kurk korralikku saaki katteloori kasutamata, isegi sel juhul sõltub saagikus oluliselt ilmastikust. Peale katteloori kasutamise aitab kurgi soojusnõudmisi täita erinevate multšide kasutamine peenral. Käesoleva töö eesmärk oli välja selgitada erinevate multšide (valge/must ja must kile, põhk) mõju avamaakurgi saagikusele. Tehti põldkatse leidmaks, kui suurel määral katses olnud multšid mõjutasid hariliku kurgi saagikust võrreldes kontrollvariandiga. Hariliku kurgi sordiks valiti ´Dirigent F1´. Katse jaoks rajati kolm rida peenraid, millest igal real oli kaheksa katselappi. Iga katselapi pikkus oli 3 m ja laius 75 cm. Pool katsealast kaeti pärast istutust kattelooriga, mida hoiti peal kuni esimese saagikorjeni. Multšidena kasutati valge/musta kilet, musta kilet ja põhku. Hariliku kurgi saagikust mõjutas enim must kilemultš kattelooriga variandis, kust saadi saaki 6,98 kg/m², mida oli keskmisest saagist (3,51 kg/m²) kaks korda rohkem. Kattelooriga variantidest koristati saaki kokku 3,99 kg/m², ilma katteloorita variantidest 3,04 kg/m². Seega saadi katteloori kasutades 31,1% rohkem saaki kui ilma katteloorita.Cucumber (Cucumis sativus L.) is more sensitive vegetable than many others. In Estonia cucumber does not give decent yield without using row-cover materials and even then weather is essential variable to influence yield. In addition to row-cover materials using different types of mulch helps to fulfill cucumber’s temperature requirements. The purpose of this study was to find out how different types of mulch (white on black- and black plastic, straw) influence cucumber’s yield. Field experiment was conducted to find out how much used mulches had effect on cucumber yield compared to control study. Cucumber variety ’Dirigent F1’ was used. Three beds were made for the field experiment, each had eight trial plots. Half of the field experiment was covered with non-woven fleece cover after planting and it was removed before the first yield. Used mulches were white on black plastic, black plastic and straw. The yield of cucumber was most influenced by using black plastic mulch and non-woven fleece cover together, which gave productivity of 6,98 kg/m² that was almost twice as average productivity (3,51 kg/m²) of experiment. Total productivity while using non-woven fleece was 3,99 kg/m² and without row-cover material productivity was 3,04 kg/m². Thus using nonwoven fleece gave 31,1% more yield than not using row-cover
