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 ...

A root-zone soil regime of wheat: physiological and growth responses to furrow irrigation in raised bed planting in northern China

Different irrigation methods in wheat (Triticum aestivum L.) result in different water and nutrient use efficiencies and, ultimately, plant growth. A field experiment was conducted during the 2006–2007 and 2007–2008 crop cycles to investigate the effects of furrow irrigated raised bed planting and the effects of flood irrigated conventional planting on growth and productivity in winter wheat. In ...

Effects of green manure and compost of pea plant on wheat

Cereal based cropping systems have been established for food security in many countries where farmers use plenty of chemical fertilizers, but adoption of leguminous crop in the system is not popular. Excessive use of fertilizers is responsible for health and environmental hazards. Adoption of legume in cereal based cropping systems and improvement of organic fertilizer are needed to reduce ...

Relationship between Phosphorus and Nitrogen Concentrations in Spring Wheat

Efficient management of P in crop production requires the development of tools to quantify the P status of plants. Our objectives were to establish the relationship between P and N concentrations of spring milling wheat (Triticum aestivum L.) during the growing season and, in particular, to determine the critical P concentration required to diagnose P deficiency. Shoot biomass and P and N ...

Effect of exo-polysaccharides producing bacterial inoculation on growth of roots of wheat (Triticum aestivum L.) plants grown in a salt-affected soil

Abstract: Effect of soil salinity on physico-chemical and biological properties renders the salt-affected soils unsuitable for soil microbial processes and growth of the crop plants. Soil aggregation around roots of the plants is a function of the bacterial exo-polysaccharides (EPS), however, such a role of the EPS-producing bacteria in the saline environments has rarely been investigated. Pot ...

Cattle gain and crop yield for a dryland wheat-sorghum-fallow rotation

Increasing pumping costs and declining well capacities in the U.S. Southern High Plains have led to greater reliance on less productive and inherently riskier dryland cropping systems. Dryland wheat (Triticum aestivum L.) and grain sorghum [Sorghum bicolor (L.) Moench] are typically grown in a 3-yr wheat-sorghum-fallow (WSF) rotation that may be intensified by integrating cattle (Bos taurus) ...

Leaching and utilization of nitrogen during a spring wheat catch crop succession

An experiment covering a 2-yr spring wheat (Triticum aestivum L.) catch crop succession was conducted in lysimeters to account for the losses of N due to leaching. We sought to relate these losses to the N uptake of the main crop and to integrate the estimated N loss and uptake into a balance. The non-winter hardy catch crops [yellow mustard (Sinapis alba L.), Phacelia (Phacelia tanacetifolia ...

Occurrence of condensed Tannins in Wheat and feasibility for reducing pasture bloat

Bloat can be a serious problem for ruminant livestock grazing pastures of winter wheat (Triticum aestivum L.) in the southern Great Plains. Tannins in forage can reduce the incidence and severity of bloat. We measured the content and variability of total phenolics and condensed tannins (CT) in forage extracts from wheat varieties and experimental lines (ExpLines) to assess the feasibility of ...

Potassium induced salinity tolerance in wheat (Triticum aestivum L.)

Water culture experiments were conducted to study the response of ten wheat genotypes to external K application (10 mmol KCI dm_3) at seedling stage under saline condition (0 and 100 mmol NaCl dm_3). The data showed that there was an increase in the shoot and root length with the application of external K. The increase was more pronounced under control than under saline conditions. The better ...

Post Harvested Stored Wheat Grain: Fungal Infestation and Nutrition

The wheat grain production in any country varies from year to year and hence the grains should be stored strategically from years of overproduction for the use in year of under production. Also grain must be stored for several other reasons such as point of ...

Spatial analysis of early wheat canopy normalized difference vegetative index

Efficient use of real-time canopy sensors requires knowledge of the scale (resolution) of variation in the measured canopy property. Knowing the amount of needed optical data requires estimation of the optimal combination of physical sensor density (number of sensors along the applicator boom) and sensor output density (sensor readings per unit distance along the travel path). The objective of ...

Genotypic and environmental interaction in advanced lines of wheat under salt-affected soils environment of Punjab

Wheat cultivars of diverse origin including approved varieties of different provinces of Pakistan i.e. Punjab, NWFP and Sindh were tested against different salinity levels in laboratory as well as in naturally saline fields in different ecological zones. Initially, 16 genotypes were studied for germination test at 6 different salinity levels ranging from 0-25 dS/m (2, 5, 10, 15, 20, 25, EC= ...

Winter wheat and maize response to urea ammonium nitrate and a new urea formaldehyde polymer fertilizer

Slow release N fertilizers have potential to improve yield and nitrogen use efficiency (NUE) in winter wheat (Triticum aestivum L.) and maize (Zea mays L.). A slow release urea formaldehyde polymer (UFP) was compared with aqueous urea ammonium nitrate (UAN) [(NH2)2CO, NH4NO3] during a 2-yr field experiment in North Carolina. Crops were grown on Candor (sandy, siliceous, thermic Grossarenic ...

Sensitivity analysis of the CERES-wheat model for variations in CO₂ and meteorological factors in Northwest Turkey

Plant growth is very sensitive to variations in atmospheric factors. Possible effects of climate change on plant growth can be estimated and evaluated using the crop growth simulation models. In this study, the CERES (Crop Environment Resource Synthesis)-wheat model was applied to two consequent growing seasons (1997–1998 and 1998–1999) in order to determine the model sensitivity on the changes ...
