“…Of the two most widely cultivated buckwheats, tartary buckwheat has higher rutin content than common buckwheat (Chauhan et al 2010;Gupta et al 2012); however, on account of its bitter taste, tartary buckwheat is rarely consumed. Korea, China, and Japan are the main growing areas of common buckwheat due to its use as a functional food (Kim et al 2001;Jung et al 2015).…”

Buckwheat is an important grain crop known for its nutritional value and content of bioactive compounds, particularly rutin. In this study, we characterized diverse Fagopyrum esculentum Moench germplasm for the diversity of agro-morphological characteristics and the rutin and quercetin content in seeds under the spring cultivation. Of the 251 germplasm accessions assessed, 193 had red stems, 182 had a pale brown seed coat color, and 238 had ovate seeds. The times taken to reach 50% flowering and 80% maturity ranged from 38-45 to 73-95 days, respectively. The 1000-seed weight (TSW) varied from 21 to 42 g. Overall, the content of rutin and quercetin ranged from 7.22-47.86 to 0-1.22 mg/100 g DW, respectively. The number of days to flowering and maturity showed negative correlations with TSW and rutin and quercetin content. However, we found that at 73-80 days after sowing, early-maturing germplasm had significantly higher mean rutin content than either intermediate-or late-maturing germplasm.The TSW weight showed a positive correlation with the content of rutin and quercetin. We identified promising accessions based early maturity (\ 80 days), higher seed weight (C 35 g) and higher content of rutin (C 35 mg/100 g DW) and quercetin (C 1 mg/100 g DW). These accessions will help to enhance grain yield and the rutin and quercetin content in existing buckwheat cultivars for spring cultivation.

“…Again, despite the interaction, higher values for FNN were seen in November, December, January and February compared to October, March, April and May, with a gradual reduction towards October and May. Variability in the number of nodes between buckwheat cultivars and between sowing dates was found by Jung et al (2015) in Central Korea. In Brazil, in the same place as the present experiments, Rocha et al (2018) found that the final number of nodes in soybeans varies with the photoperiod to which the plant is exposed during the vegetative phase (emergence until the appearance of the last node) and differs between cultivars, with the lowest values seen in early sowings (September) and late sowings (January and February).…”

“…The buckwheat plant is sensitive to frost, heat, water deficit and photoperiod (Jacquemart et al, 2012), and genotypes have shown different development in different environments (Facho, Farhatullah, Khalil, Khan, & Ali, 2016;Fesenko, Romanova, & Fesenko, 2012;Jung et al, 2015). Therefore, varying the conditions of temperature, insolation, solar radiation, photoperiod and rainfall between sowing dates can influence vegetative development in the plant.…”

“…The final number of nodes and the period of node emission, between emergence and emission of the last node, are important in helping to characterise the vegetative development of the plants. Research involving aspects related to node emission and sowing dates has been carried out on buckwheat (Fesenko et al, 2012;Jung et al, 2015;Mikhailovich, 2019) and soybeans (Martins, Radons, Streck, Knies, & Carlesso, 2011;Rocha et al, 2018), showing different plant responses to environmental variations, and highlighting the direct association between the number of nodes and leaf area, responsible for intercepting solar radiation and biomass accumulation (Xue, Weiss, & Baenziger, 2004).…”

The aim of this study was to determine the rate of node appearance (RNA), the final number of nodes (FNN) and the period of node emission (PNE) in two buckwheat cultivars (Fagopyrum esculentum Moench) for different sowing dates, and to check variability in the RNA, FNN and PNE between the cultivars and sowing dates. The IPR91-Baili and IPR92-Altar cultivars were evaluated for 29 and 31 sowing dates from October to May in the 2017/2018 and 2018/2019 agricultural years respectively. In each experiment, a completely randomised design with five replications was used. The number of nodes (NN) on the main stem was counted twice a week in each plant (replication), from emission of the first node until the end of the cycle. The linear regression (y = a + bx) of the number of nodes (NN, y) was adjusted for each plant based on the number of days after emergence (DAE, x). The rate of node appearance (RNA), in days node-1, was determined from the inverse of the slope of the linear regression between NN and DAE (RNA = 1/b). The RNA was calculated for the period of node emission (PNE, in days), i.e. from emergence to emission of the last node. The final number of nodes (FNN) was counted at the end of node emission. Variability was found in the rate of node appearance (RNA), the final number of nodes (FNN) and the period of node emission (PNE) between the cultivars and sowing dates. The rate of node appearance ranges between 2.20 and 8.23 days node-1, the final number of nodes between 2.20 and 17.20, and the period of node emission between 16.60 and 49.20 days. Plants of the IPR91-Baili and IPR92-Altar cultivars show better vegetative development (lower RNA, higher FNN and greater PNE) when sown in November, December, January and February, compared to those sown in October, March, April and May.

“…In this manner, the plants will be of high yield if they can significantly use the production elements and store more assimilates in their organs with regard to their growth conditions. In a test in Korea, the effect of planting time on growth and yield of buckwheat was investigated and reported that grain yield was 1190 kg ha -1 in spring and 1580 kg ha -1 in summer [63]. Kalinova and Dadakova (2009) presented the yield of 1500 kg ha -1 for the buckwheat [64].…”

In order to evaluate the active ingredient, grain yield of common buckwheat (fagopyrum esculentum) affected by sowing date, planting pattern and nitrogen in summer cultivation, a field study was conducted during 2018 and 2019 in Agricultural Research Institute of Arak, Iran. The experimental design was regarded as the randomized complete blocks in the form of split-plot factorial with three replications. Planting pattern treatments as the primary factors included two levels of 50 cm mound with two 20cm sowing rows (P1) and 60cm mound with three 15cm sowing rows (P2). Sowing date treatments included four levels of 20 th June (D1), 5 th July (D2), 20 th July (D3) and 5 th August (D4) and nitrogen treatments included four levels of 0 (N1), 50 (N2), 100 (N3) and 150 (N4) kg ha -1 considered as secondary factors. Results showed that the effects of planting dates, nitrogen and planting patterns have been significant on grain yield, rutin percent rates of leaves, stem, grain and flower. So, the highest rates of grain yield as 1967 kg ha -1 , leaf, stem, grain and flower rutin percent as 0.99, 0.37, 0.007 and 1.35 mg per 100 g of dry matter have been observed for the treatments of P2D1N3, P2D4N4, P1D4N4, P1D4N3 and P1D 4 N 3 ; respectively. Therefore, buckwheat with nutritional characteristics, adaptation, good yield as a new medicinal plant can enter the cultivation patterns in different regions of the world.
