Improving Cereal Storage Facilities with Gas Sensing
Storage of cereal crops and other foodstuffs is an essential part of ensuring a sustainable and robust food supply. Cereal crops are typically harvested between mid-July to mid-September but with careful storage can be kept for periods longer than a year.1 Successful storage of cereals involves the balance of a variety of environmental conditions to ensure the maintenance of quality and the ...

Growth and yield response of rice varieties to foliar application of Boron | JBES 2020 @environmentalxpart
Abstract A field experiment was conducted during the Kharif season of 2018-19 at Rice Research Station Bahawalnagar on the calcareous sandy loam soil to assess the effect of foliar application of boron on growth & yield components of rice varieties (Kissan & Punjab Basmati 2016).The foliar application of boron aqueous solution was used as treatments comprised of control, 0.5kg/ha, ...

Managing Moisture: Navigating Drydown Decisions
This season has been, without a doubt, one of the wettest since 2009. In many states, the excessive rain led to flooding and late planting. On my family farm in North Central Iowa, like on many farms throughout the Corn Belt, it was so wet that we couldn’t get into the field to plant on schedule. And the continued wet weather means that now high and variable grain moisture levels are ...

Detecting salinity stress in crops
Salinity inhibits growth and development in crops. Due to the extent of damage salinity causes to agriculture, it is identified as a major threat to food production. Therefore, practices to deal with the effects of salinity on crops are receiving a lot of attention. To be able to provide proper recommendations that are also sustainable, it is first necessary to find out how salinity affects ...

Yield Data Errors Today, Yield Costs Tomorrow
Regardless of whether your yield data comes from your combine, grain cart, or from truck scales, each source has shortcomings that will not only influence your farm decisions but may also have a negative financial impact. This harvest growers will spend significant time and money chasing down accurate yield data from combine yield monitors, grain carts and/or truck scale tickets. Each of these ...

Hormonal changes caused by the xenia effect during grain filling of normal corn and high-oil corn crosses
The xenia effect results from the cross-fertilization of nonrelated lines of crops, which causes a grain to produce a germ or embryo that is much larger than average. It is a significant genetic component in TopCross grain production systems, which can affect grain yield and quality. This study measured hormone variations during grain filling of normal corn (Zea mays L.) hybrids, and normal corn ...

Effects of the chromosome region including the Gpc-B1 locus on wheat grain and protein yield
The recent cloning of the Gpc-B1 gene from Triticum turgidum ssp. dicoccoides (Körn. ex Asch. and Graebn.) Thell. (DIC hereafter) chromosome 6BS revealed that modern wheat varieties have a nonfunctional allele. The DIC allele accelerates senescence and increases grain protein concentration (GPC) relative to the nonfunctional allele, but its effect on yield is not known. Here we describe the ...

Maize morphophysiological responses to intense crowding and low nitrogen availability: an analysis and review
Mounting concerns over the cost and environmental impact of N fertilizer combined with progressively higher plant densities in maize (Zea mays L.) production systems make progress in maize N use efficiency (NUE) and N stress tolerance essential. The primary objectives of this 3-yr field study were to (i) evaluate the N responsiveness, NUE, and N stress tolerance of multiple modern maize genotypes ...

Effect of variation for major growth habit genes on maturity and yield in five spring wheat populations
Segregation at major genes controlling plant height, photoperiod response, and vernalization response in wheat (Triticum aestivum L. em. Thell.) may have pleiotropic effects on several traits. Allelic variation at these loci can be monitored using polymerase chain reaction (PCR) markers. The effect of segregation at these loci on maturity and agronomic traits was measured for sets of recombinant ...

Relationships between large-spike phenotype, grain number, and yield potential in spring wheat
Our objective was to investigate the physiological basis of grain number per square meter (GN) and yield in two CIMMYT spring wheat (Triticum aestivum L.) lines of large-spike phenotype (LSP), LSP1 and LSP2, and one check cultivar, Bacanora, when grown as single plants in the growth room and at normal sowing densities in high radiation, irrigated field conditions. In the growth room, rachis ...

Mapping of QTL associated with maize weevil resistance in tropical maize
The maize weevil (MW), Sitophilus zeamais (Motsch.), is an important pest of stored maize (Zea mays L.) in tropical areas. Quantitative trait loci (QTL) associated with MW resistance were analyzed. A total of 163 F2 progeny derived from the cross CML290 (susceptible) x Muneng-8128 C0 HC1-18-2-1-1 (resistant), were genotyped with 151 molecular markers. Resistance was evaluated using bioassays on ...

Production of dryland barley for human food: quality and agronomic performance
Grain β-glucan content is the most important attribute for barley (Hordeum vulgare L.) varieties destined for the human food market. This trait is important because of the blood glucose and cholesterol-reducing properties of β-glucans. High levels of grain protein content, test weight, and seed size and endosperm color may also add value. Seed yield potential, in part, determines the ...

Wheat grain quality response to tillage and rotation with field Pea
Preceding spring wheat (Triticum aestivum L.) with field pea (Pisum sativum L.) can enhance wheat grain yield in a wheat-pea (WP) rotation compared with continuous wheat (WW). The pea-rotation benefits to wheat grain quality are uncertain. A 6-yr study was conducted to determine (i) if grain protein content, kernel weight, and test weight were enhanced for wheat in a WP rotation compared with WW, ...

Breeding effects on grain filling, biomass partitioning, and remobilization in mediterranean durum wheat
This work assesses the changes resulting from durum wheat (Triticum turgidum L. var. durum) breeding in Italy and Spain during the 20th century on grain filling, biomass production, and allocation at anthesis, and the remobilization of preanthesis photosynthates to the grain of main stems. Field experiments, involving 12 Italian and 12 Spanish cultivars released at different periods, were ...

Rice seeding and nitrogen rate effects on yield and yield components of two rice cultivars
Field research was conducted for 2 yr to investigate the relationship between rice (Oryza sativa L.) seeding rate and preflood nitrogen (N) rate utilizing long-grain rice cultivars planted into clay and silt loam soils. Rice cultivars included ‘Cheniere’ and ‘Wells’ seeded at 162, 323, and 646 seeds m–2. Nitrogen was applied before flooding at 67, 134, and 202 kg ha–1. No response to soil texture ...

White wheat grain quality changes with genotype, nitrogen fertilization, and water stress
The production of hard white winter (HWW) wheats (Triticum aestivum L.) with acceptable protein content and quality over different environments requires the correct combination of genotypes and management practices. The objectives of this study were to evaluate moisture deficit and N management on grain protein and quality of seven HWW and two soft white winter (SWW) genotypes, and to identify ...

Seeding rate and nitrogen management effects on spring wheat yield and yield components
Seeding rate, N level, and N application timing are key management factors for spring wheat (Triticum aestivum L.) production in North Dakota. Experiments were conducted under dryland (Casselton, ND) and irrigated (Carrington, ND) conditions in 2003 to 2005 to determine the optimum combination of seeding rate and N management to maximize yield of hard red spring wheat (HRSW). Treatments consisted ...
