EXPLOITATION OF EM.1-TREATED BLEND OF ORGANIC RESOURCES AND HUMIC ACID FOR ORGANIC BERSEEM (Trifolium alexandrinum L.) PRODUCTION

Ihsanullah DAUR , Awad Osman ABUSUWAR, Fahad ALGHABARI

Abstract

A field trial was conducted to evaluate blends of organic resources and humic acids, in order to enhance organic berseem forage production. The objective of this study was to compare an EM.1 (effective microorganisms)-treated blend of organic resources with an untreated blend of organic resources, and thereby evaluate the usefulness of humic acid as an organic fertilizer. The two types of blends,each with 4 application levels(0, 15, 30, and 45 t·ha−1 ), and humic acid (4 application levels: 0, 15, 30, and 45 kg·ha−1 ) were evaluated using a randomized complete block design with a split-plot arrangement (blend types were the main plot factor and humic acid a sub-plot factor). Except for the difference in EM.1 inoculation, both blends were prepared by co-composting cow manure, poultry manure, and kitchen waste (2:1:1 ratio by volume, respectively). The differences among treatments with respect to fresh and dry yield, as well as mineral composition were recorded. The blend treated with effective microorganisms was found to be a more effective fertilizer than the untreated blend. Additionally, heavier application of both types of organic resource blends and humic acid enhanced both fresh and dry yields, and improved the mineral composition of the crop. These findings are valuable for organic growers and it may open a new avenue for researchers worldwide.

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
