“…In the total turnover of all grains in the world, wheat participates with 50%, while in production with 30% [18]. Therefore, this crop represents one of the most important crops in the world economy, and its market and prices often have a significant impact on the global economy and trade.…”

For this research we are selected three indicators of wheat: yield (t/ha), producer price (USD/t) and share of the harvested area under wheat in relation to the total land area of country (%). The mentioned indicators were analyzed for the period 2006-2021 in thirty-two European countries. The purpose of the research is to determine which of the mentioned indicators achieve average annual growth/decrease rates, what is the correlation between them, how European countries are grouped with their similarities and differences. The research examines the impact of the COVID-19 pandemic on the mentioned indicators in a two time phases: Phase I, before the pandemic (2006-2019); Phase II, during the pandemic (2020-2021). The methodological approach to the research topic involved the application of descriptive statistics, as the method of principal components analysis (abbr. PCA) with graphics. A positive correlation exists only between the yield of wheat and the share of the harvested area under wheat in the total area of the land (0.291). PCA method showed that countries are grouped differently depending on the observed indicator and the analyzed time phase.

“…Wheat is an important food crop in more than 40 countries contributing to the staple needs of one-third of the global population ( Kavamura et al., 2021 ; Nahid et al., 2022 ). It is widely cultivated in India with a total area under cultivation of 30.31 million ha, production of over 100 million tonnes, and productivity of 3314 kg per ha.…”

Core microbiota of wheat rhizosphere under Upper Indo-Gangetic plains and their response to soil physicochemical properties

Wheat is widely cultivated in the Indo-Gangetic plains of India and forms the major staple food in the region. Understanding microbial community structure in wheat rhizosphere along the Indo-Gangetic plain and their association with soil properties can be an important base for developing strategies for microbial formulations. In the present study, an attempt was made to identify the core microbiota of wheat rhizosphere through a culture-independent approach. Rhizospheric soil samples were collected from 20 different sites along the upper Indo-Gangetic plains and their bacterial community composition was analyzed based on sequencing of the V3-V4 region of the 16S rRNA gene. Diversity analysis has shown significant variation in bacterial diversity among the sites. The taxonomic profile identified Proteobacteria, Chloroflexi, Actinobacteria, Bacteroidetes, Acidobacteria, Gemmatimonadetes, Planctomycetes, Verrucomicrobia, Firmicutes, and Cyanobacteria as the most dominant phyla in the wheat rhizosphere in the region. Core microbiota analysis revealed 188 taxa as core microbiota of wheat rhizosphere with eight genera recording more than 0.5% relative abundance. The order of most abundant genera in the core microbiota is Roseiflexus> Flavobacterium> Gemmatimonas> Haliangium> Iamia> Flavisolibacter> Ohtaekwangia> Herpetosiphon. Flavobacterium, Thermomonas, Massilia, Unclassified Rhizobiaceae, and Unclassified Crenarchaeota were identified as keystone taxa of the wheat rhizosphere. Correlation studies revealed, pH, organic carbon content, and contents of available nitrogen, phosphorus, and iron as the major factors driving bacterial diversity in the wheat rhizosphere. Redundancy analysis has shown the impact of different soil properties on the relative abundance of different genera of the core microbiota. The results of the present study can be used as a prelude to be developing microbial formulations based on core microbiota.

“…Primarily wheat is being used to make chapattis (Bread) but it also contributes to other bakery products. Wheat utility and high nutritional value made it the staple food for more than 1/3 rd population of the world [3]. depend very much on the agronomic practices, seed rate (plant population) and crop geometry (spacing and plant distribution pattern) play a significant role in influencing the physical, physiological and general health of the seed.…”

Wheat (Triticum aestivum L.) is the world's most essential staple food. It is the most important crop in Himachal Pradesh during the winter season in the state's low and mid hills. Manipulation of agronomic practices such as planting pattern/geometry and seed rate is regarded as the first stage in achieving optimum plant distribution over cultivated area, resulting in greater utilization of above and below ground natural resources. A field and laboratory investigation was undertaken to study the effect of different planting patterns and seed rates on its quality in wheat by evaluating the quality parameters. The experiment with twelve treatment combinations comprising of four planting patterns (P1-15 cm, P2 -23 cm, P3 -15 x 15 cm and P4 -23 x 23 cm) and three seed rates (S1 -100, S2 - 120 and S3 -140 kg/ha) was conducted in Randomized Block Design with four replications during Rabi season of 2015-16 at experimental farm of CSKHPKV, Palampur, Himachal Pradesh, India. Observations showed that 23 × 23 cm planting patterns produced significantly (2.96%) higher 1000 seed weight, (8.08%) seedling length, (6.01%) seedling dry weight, (8.34%) vigour index –I and (6.58%) vigour index- II over normal planting patterns (23 cm), whereas other planting techniques had no appreciable impact on germination percentage. Different seed rates had no appreciable impact on 1000 seed weight, germination rate, seedling length, seedling dry weight, and vigour index. Criss cross sowing (23 x 23 cm) with 140 kg per hectare is the best combination for quality seed production of wheat.
