Due to the increasing presence of industrial hemp (Cannabis sativa L.) and its multiple possibilities use, influence different light several biopreparations based on beneficial fungi bacteria hemp’s morphological physiological properties were examined. Different their combinations inoculated seed and/or substrate grown under blue white light. A completely randomized block design was conducted in four replications within 30 days. For biopreparation treatment, vesicular arbuscular mycorrhiza...

There has always been a specific focus on nitrogen fertilization in sugar beet production due to its important effect root yield and quality. For stable growth satisfactory quality, balanced N is crucial. Thus, this study aimed investigate spring two seasons as the following treatments: N0—control, N1—only pre-sowing fertilization, N2—pre-sowing with topdressing. Four different genotypes were included (Serenada, Colonia, Fred, Danton). The experiment was set up plain area, belonging...

Industrijska konoplja se uzgajala prvenstveno kao sirovina za izdvajanje vlakna iz stabljike. Proizvodnja industrijske konoplje u Hrvatskoj zauzimala je prvoj polovini 20. stoljeća između 8.000 i 12.000 hektara. Najveće uzgojne površine bile su 1949. godine kada industrijska na oko 21.000 ha. Šezdesetih godina prošlog uzgajana prosječno 7.165 ha, s prosječnim prinosom suhe stabljike 5,81 t ha-1 od 0,88 ha-1. U narednom desetljeću (1970.-79.), smanjile 2.331 a još manje bilo zasijano...

This study analyzes the dynamics of sugar beet root, crown, and leaves fresh dry matter (FM DM, respectively) accumulation per plant their mass ratio at different densities nitrogen fertilization. The biennial field trials were set as four planting (60,000, 80,000, 100,000 140,000 plants ha-1) three methods application in spring: control – without fertilization (N0), presowing only (N1), with topdressing (N2). Close to maturation, mean DM whole on September 20, 2014 amounted 28.8, 7.3 4.0 t...

In the past, Croatia had industrial hemp cultivation mainly for fiber obtainment. Recently, interest in seed and flower production has risen worldwide. Industrial is interesting many aspects, so study evaluates current status potential of using a SWOT analysis. The average harvested area under was around 1,000 ha (2014 – 2023), with yield 0.8 t ha-1. addition to favorable agroecological conditions, considerable num-ber products medicinal properties plant provide most strength production....

Soil acidity is one of the most common problem in cultivating plants open field. Dolomite enriched with nitrogen, phosphorus and potassium (trade name Fertdolomite: 24% CaO + 16% MgO 3% N 2.5% P2O5 K2O) was applied autumn 2011 four rates (0 t*ha-1, 3.56 7.14 t*ha-1 14.25 t*ha-1). Aim this experiment testing 5-year residual impact Fertdolomit on acid soil maize winter wheat grain yield quality, as well changes properties. Five year after application, has shown positive long term effect pH...

The aim of this study was to determine the influence different pH values water solution (pH 4.5, 5.5, 6.5, 7.5 and 8.5) temperatures (10, 15 20 ºC) on fibre flax seed germination seedlings morphological characteristic (seedling root stem length total seedling length). conducted in controlled conditions by rolled filter paper 4 replicates for 7 days. average rate 84%. highest found at ºC (88%) which very significant (P<0,01) as compared 10 where it decreased 9%. share normal determined 5.5...
