INFLUENCE OF METEOROLOGICAL PARAMETERS ON THE YIELD AND CHEMICAL COMPOSITION OF COMMON BUCKWHEAT (Fagopyrum esculentum Moench)

Abstract

Common buckwheat (Fagopyrum esculentum Moench) is an annual plant from Polygonaceae family which is well known as pseudocereal with high nutritional value. The yield and quality of the buckwheat`s kernel depend on weather conditions, mainly due to variations in the air temperatures and precipitation during the growing period. The aim of this study was to determine the impact of some metrological parameters on yields and chemical compositions in the kernel of buckwheat. Field experiments were conducted during three years (2011, 2012 and 2013) in the village Donje Selo, near Ilijaš. In this study grain yield, protein content, sludge, fats, mineral matter, cellulose and total phenols were determined. Experimental results suggested that the weather conditions in different years of the research have a significant impact on the yield and the chemical composition of the kernel. The yield of buckwheat varied from the year to year and ranged from 0.98 to 1.29 tons per hectare. Contents of protein and starch were also significantly dependent on the year of the research, as well as the content of phenol in the kernel. High total phenolic content was recorded in the year with the highest average monthly air temperature.

Sensitivity of yellow foxtail (Setaria glauca L.) and barnyardgrass (Echinochloa crus‐galli L.) to aqueous extracts or dry biomass of cover crops

“…Nevertheless, combined sowing of E. crus‐galli and F. esculentum in a previous study led to significant underdevelopment of weed roots 41 . This apparent difference may reflect that allelopathic toxins may be secreted by F. esculentum only under stress conditions such as drought or high temperature, 42 which was not the case in the present study with temperatures only slightly higher than multi‐year average long term and without drought period (data not shown). Although more weakly than Brassicaceae CCs, aqueous extract of G. abbyssinca inhibited weed growth (Table 3), which may reflect its relatively high content of phenolics such as coumarin and gallic acid, which are known to inhibit weed growth and development 43 .…”

Comparison of Plant Morphology, Yield and Nutritional Quality of Fagopyrum esculentum and Fagopyrum tataricum Grown under Field Conditions in Belgium

“…We observed that the yield was maintained despite the hot and dry periods that occurred in summer in Belgium over these last few years. However, meteorological parameters were shown to significantly affect buckwheat yields and drought and high temperature could decrease average yield [ 15 , 36 ]. Although both species could be affected by drought and heat stress mainly regarding reproductive growth, it was shown that they develop resistance mechanisms and that F. tataricum was less affected by water stress than F. esculentum [ 13 , 14 ].…”

“…Buckwheat seeds are known to be rich in high quality carbohydrates, protein and amino acid, fatty acid, vitamins, minerals and bioactive compounds such as polyphenols [ 22 ]. However, the total content of components depends on variety or environmental factors [ 2 , 15 , 36 ]. We observed that both species differed by their protein and mineral content in the seeds ( Figure 1 ).…”

THE INFLUENCE OF SOW DENSITY ON PRODUCTIVITY AND MOISTURE IN BUCKWHEAT GRAIN (Fagopyrum esculentum Moench.) IN CONDITION OF STUBBLE SOWING AND IRRIGATION

“…Omid Beygi et al (2002) studied effects of different nitrogen amounts and sowing density on plants growing, grain yield and rutin content and concluded that density of 100 plants per m -2 and total amount of 100 kgN per ha -1 give the best results. Gavric et al (2018) registered significant influence of sowing density and meteorological conditions on grain yield of buckwheat, too, but not to chemical compose of grain. Increasing sowing rate had positive effect on grain yield, but it had no effect on chemical compose of kernel.…”
