Genotypes variation of Medicago sativa (L.) seed yield components in acid soil under conditions of cross - fertilization

Abstract

Alfalfa (Medicago sativa L.) is the most important forage plant species in Bosnia and Herzegovina. In this study, conducted in Banja Luka, the investigated ten alfalfa genotypes originated from different regions of USA and Europe. The study objective was to determine their grain yield per plants and four morphological properties. The interactions analyses provided to select individual genotypes that are shown the highest stability and yield potential in different production conditions. Genotype with the highest yield shown lower stability level. The influence year and genotype on GYP - the grain yield per plants for investigated alfalfa genotypes was significant (Fexp=7.54* and Fexp= 8.34*). The highest average value for investigated parameter in the first research year had genotypes G53 and G44 and in second research year genotype G2. The lowest value in both research years had genotype G100 (0.28 kg ha-1 and 0.30 kg ha-1. Positive and strong correlations were found between the grain yield per plants and the number of pods per plants (r= 0.74**) and the grain yield per plant and the number of flower per inflorescence (r= 0.51*). On the basis of the obtained values, we conclude that we have excellent genotypes G2, G44, G53 and G51 for successful breeding work in order to obtain new high-yielding varieties of alfalfa.

The effect of fertility control on soil conservation as a basic resource of sustainable agriculture

“…Plant nutrients can be provided by mineral, organic or organo-mineral fixation or the weathering of soil minerals (Milunović et al, 2022;Lakić et al, 2022;Kosev et al, 2022;Bakmaz et al, 2023;Vasileva et al, 2023). The fertilizer industry produces mineral or manufactured fertilizers which content nitrogen, phosphorous and potassium, (or NPK), which are the primary nutrients in plant nutrition and also in manufactured fertilizers.…”

Impact of agro-ecological conditions and fertilization on yield and quality of triticale on pseudogley soil

“…Unfavourable weather conditions (high and low temperatures, high amounts of precipitation with stormy and strong winds, drought, acidic and salty soils) have a strong negative impact on the production of triticale and represent a great risk, because they limit the manifestation of the maximum genetic potential of the cultivated crop (Fraś et al, 2016;Dubis et al, 2017;Kizilgeci and Yildirim, 2017;Bielski et al, 2020;Dražic et al, 2021;Kosev et al, 2022;Milunović et al, 2022;Lakić et al, 2022). Due to climate change, Laidig et al (2022) point out that increased efforts of breeders are needed to create new lines and varieties of triticale that would be tolerant to diseases and lodging.…”

Environment and Digestate Affect on the Oats Quality and Yield Parameters

“…The meteorological conditions, monthly precipitation and air temperatures for 2021 and 2022 during the trial were taken from the Hydro-meteorological service of Republic of Serbia, Pancevo (Table 1). Precipitation have a decisive influence on the yield components (Howarth et al, 2021;Lakić et al, 2021;2022a;2022b;Ljubičić et al, 2021;2023;Nikolić et al, 2022;Dražić et al, 2022;Rakaščan et al, 2021;Dimitrijević et al, 2022;Filipović et al, 2022;Milunović et al, 2022;Popović et al, 2011;2020a-b;Kosev et al, 2022). Average temperatures in the growing season were 19.25°C in 2021. and 19.03°C in 2022., while total precipitation in 2022 was 351.4 mm and it was higher by 23 mm then in 2021, figure 1.…”
