Fertilizer effect on some basil bioactive compounds and yield

Abstract

Basil (Ocimum basilicum L.) is an annual plant that belongs to the Lamiaceae family. It is used as an aromatic and medicinal plant. Basil is grown in different regions with varying climates; the productivity and quality are influenced by both abiotic and biotic factors. This study was aimed to determine the impact of the application of different types of fertilizers on the yield and contents of some bioactive components in basil. The treatments consisted of three different types of fertilizers (mineral, organomineral, and organic) and control (without fertilization). The yield per plant and the essential oil content with fertilizer treatment were better than that in control. The highest fresh yield (450.9 g per plant) and oil content (0.94 mL 100 g-1) were recorded in basil cultivated using mineral fertilizers. Furthermore, the fresh yield (333.9 and 327.8 g per plant) and oil content (0.87 and 0.85 mL 100 g-1) were higher after the application of organic and organomineral fertilizers compared to that in the control treatment. There was no significant effect of fertilizer application on the total phenolics, total flavonoids, and antioxidant capacity. This study demonstrated a suitable practical application of organomineral fertilizers as a nutrient source in basil crop production in areas where the use of mineral and organic fertilizers is limited.

Response of Basil (Ocimum basilicum) Growth and Yield to Planting Densities and Row Arrangements in Tomato-Basil Intercropping System

“…This could be since at wider row spacing, the competition between the plants reduces, and hence, each plant has more space and produces more leaves. In addition, the essential oil content of plants under high light was more than that of plants grown with low light as biosynthesis of essential oil is highly dependent on light conditions (Gavrić et al 2021). In line with this, Mirjalili and Poorazizi (2014) reported that two-row cultivation of basil, with low density, resulted in a higher yield of essential oil.…”

Factibility of growing basil as an alternative crop for adaptation to climate change in Bosnia and Herzegovina

“…Plants grown in Butmir were 40% taller, and their yield was 2.5 times higher than those in Kakanj. Nurzynska-Wierdak et al (2011), Al-Huqail et al (2020), and Gavrić et al (2021 state that air temperature and soil fertility are the most important factors affecting growth and yield of basil plants. Analysis of these traits in our study indicated that the air temperature had no effect on growth and yield of basil ---g plant -1 ---mL 100 g -1 mg GAE g -1 µM Fe plants, whereas soil properties influenced these studied traits.…”

“…Plant extracts were prepared according to the cold extraction method (Gavrić et al, 2021). In brief, 0.5 g dried and powdered aerial parts were transferred to flasks and mixed with 50 mL 60% ethanol.…”

“…The quality and medicinal value of basil depend on bioactive phytochemical components such as phenols, flavonoids, alkaloids, and tanins (Zareen et al, 2014). Although the contents of these components in the plant are regulated by genetic processes, they are also strongly influenced by many abiotic factors, including growing location, weather conditions, UV radiation, altitude, salinity, etc., that cause changes in the growth of plants, as well as the quantity and quality of their bioactive phytochemical components (Gavrić et al, 2021). Due to its resistance to high summer temperatures and an expected future increase in temperature in Bosnia and Herzegovina caused by climate change, our hypothesis is that basil may be considered as an alternative to traditional crops, since in the future, with the continued global warming, favorable environmental conditions still exist in Bosnia and Herzegovina for growth and development of basil.…”

ENHANCEMENT OF GUAR GROWTH AND PRODUCTIVITY BY BradyrhizobiumINOCULATION UNDER DIFFERENT NPK FERTILIZATION LEVELS

“…Nitrogen (N), phosphorus (P) and potassium (K) are essential nutrient elements in plant development and growth as will as they are involved in nucleic acid metabolism, protein synthesis, photosynthesis, carbohydrate metabolism, enzyme activity and nitrogen fixation (Thakur and Sharma, 1997;Barbulova et al, 2007;Qin et al, 2012). Gavrić et al (2021) pointed out that the herb fresh and dry yield per plant with fertilizer NPK fertilization (7:20:30) treatment were better than control (unfertilized basil plants). Among the different NPK treatments, the application of NPK fertilization at 6:3:3 rates gave the highest values for growth traits, root parameters and greenness level of Salvadora persica plant (Lasheen et al, 2021).…”
