Kenevir (Cannabis sativa L.) Cannabinaceae familyasına ait, 2n=20 kromozomlu, tek yıllık ve yabancı döllenen bir bitkidir. Bu bitki dünyanın eski kültür bitkilerinden biri olup, günümüzde birçok farklı alanlarda kullanılmaktadır. Ülkemizde kenevir tarımının gündeme gelmesiyle birlikte, pek çok alanda bilimsel çalışmalara ihtiyaç olduğu anlaşılmıştır. Kenevirin lif üretimi amacıyla sera koşullarında ve saksıda üretimi planlandığında uygun ekim sıklığının ne olabileceğinin belirlenmesine ihtiyaç duyulmuştur. Bundan dolayı bu araştırma, Yozgat Bozok Üniversitesi Kenevir Araştırmaları Enstitüsü Ar-Ge serasında 2023 yılında yapılmıştır. Deneme, Tesadüf Parselleri Deneme Desenine göre üç tekerrürlü olarak yürütülmüştür. Denemede 20 lt’lik saksılara (28x26 cm), Narlı ve Fedora 17 kenevir çeşitlerinin tohumları ekilmiştir. Çalışmada saksılara yapılan ekimlerde 8 farklı sıklık (1, 2, 3, 5, 10, 15, 20, 25 adet bitki/saksı) incelenmiştir. Çalışmada, bitki boyu, sap çapı, biyokütle verimi, kuru sap verimi, lif verimi ve lif oranına ait bulgular incelenmiş olup, deneme desenine uygun varyans analizleri yapılarak bulgular değerlendirilmiştir. Çalışmada elde edilen lif verimleri Fedora çeşidinde 18,4-35,0 g/saksı arasında değişim göstermiştir. En yüksek verim 20 bitki sıklığında görülmüştür. Narlı çeşidinin dişi bitkilerinde 14,4-25,1g/saksı arasında değişim göstermiştir. Narlı çeşidinin erkek bitkilerinde ise lif verimi 12,5-21,4 g/saksı arasında değişmiş ve en yüksek verim 20 bitki sıklığında görülmüştür. Sera koşullarında kuru sap ve lif verimi esas alındığında, denemede kullanılan her iki çeşit için de bitki sıklığının saksı başına 20 adet bitki olduğu sonucuna varılmıştır.

Determination of Suitable Sowing Frequency of Cannabis in Greenhouse Conditions

Öz

Cannabis (Cannabis sativa L.) is an annual and foreign fertilized plant with 2n=20 chromosomes, belonging to the Cannabinaceae family. This plant is one of the oldest cultivated plants in the world and is used in many different sectors today. With the introduction of hemp agriculture in our country, it has been understood that there is a need for scientific studies in many sectors. When hemp is planned to be produced in greenhouse conditions and in pots for fiber production, there is a need to determine the appropriate planting frequency. Therefore, this research was conducted in the R&D greenhouse of Yozgat Bozok University Hemp Research Institute in 2023. The experiment was conducted with three replications according to the Coincidence Plots Experimental Design. In the experiment, seeds of Narlı and Fedora 17 cannabis varieties were sown in 20 liter pots (28x26 cm). In the study, 8 different densities (1, 2, 3, 5, 10, 15, 20, 25 plants/pot) were examined. In the study, plant height, stem diameter, biomass yield, dry stem yield, fiber yield and fiber ratio were examined and the findings were evaluated by performing variance analysis in accordance with the experimental design. The fiber yields obtained in the study varied between 18.4-35.0 g/pot in Fedora variety. The highest yield was observed at 20 plant density. In the female plants of Narlı variety, it varied between 14.4-25.1 g/pot. In male plants of Narlı variety, fiber yield varied between 12.5-21.4 g/pot and the highest yield was observed at 20 plant density. Based on dry stem and fiber yields under greenhouse conditions, it was concluded that the plant density for both varieties used in the experiment was 20 plants per pot.
