Tilletia species on winter wheat grain

Predicting Grain Protein Content of Winter Wheat

The objective of this paper is to propose to use a new Improved Particle Filtering (IPF) based on minimizing Kullback-Leibler divergence for crop models' predictions. The performances of the method are compared with those of the conventional Particle Filtering (PF) at a complex crop model (AZODYN) to predict an important winter-wheat quality criterion, namely the grain protein content. Furtherm...

Effect of urea foliar feeding on grain protein content and quality in two winter wheat cultivars

Winter Wheat Grain Yield and Grain Nitrogen as Influenced by Bed and Conventional Planting Systems

Bed planted wheat systems offer a new alternative for the traditional wheat producer to provide opportunities for crop rotation, more efficient use of water, and new techniques of nutrient management. This study was conducted to determine if planting winter wheat (Triticum aestivum L.) in Oklahoma on raised beds can maintain grain yields while providing more options in the cropping system. Expe...

Coating seeds with endophytic fungi enhances growth, nutrient uptake, yield and grain quality of winter wheat

The aim of this study was to assess whether seed coating with microbialconsortium based on the arbuscular mycorrhizal (AM) fungus Glomus intraradicesBEG72, Glomus mossae and Trichoderma atroviride MUCL 45632 could improveseedling establishment, yield and grain quality (protein content and mineralcomposition) of wheat (Triticum durum Desf.). As a first step, a laboratoryexperiment was conducted ...

The effect of post-anthesis water supply on grain nitrogen concentration and grain nitrogen yield of winter wheat

The effect of water supply during grain growth on grain nitrogen concentration (GNC) and grain nitrogen yield (GNY) of winter wheat (Triticum aestivum L.) was studied in the field experiment on fertile loamy-clay soil in years 2004–2007. The water regime was differentiated using mobile rain shelter (water shortage, treatment S) and drip irrigation (ample water supply, treatment W); rain-fed cro...
