Hulled Wheats

The objective of this study is to compare the yields and qualities of the hulled wheats emmer (Triticum dicoccum Schübl.) and spelt (Triticum aestivum L. ssp. spelta) with the commonly cultivated naked wheats common wheat (Triticum aestivum L. ssp. vulgare) and durum wheat (Triticum durum Desf.). Three years of field experiments were carried out from 2015 to 2017 in the Lubelskie province (Poland) on rendzina soils. The experimental results indicate that the hulled wheats, even when cultivated with advanced technology, produced lower yields compared to the common and durum wheats (reduced by 30–56%). In spite of their lower yields, emmer and spelt retained appropriate technological parameters. Higher ash, protein, and wet gluten yields were characteristic of the hulled wheats; however, the high gluten spread of emmer (13.3 mm) may limit its application as a raw material in some food processes. In summary, hulled wheat species can be recommended for modern agricultural production as an alternative source of high-quality materials for the agricultural and food industries.

The effects of different densities of volunteer wheat (Triticum aestivum L. ’Neepawa’) on the yield of canola (Brassica campestris L. ’Tobin’ and B. napus L. ’Westar’), and the seed yield of the volunteer wheat were determined in field experiments conducted at Vegreville, Alberta and Scott, Saskatchewan. Hyperbolic models provided a good fit to the data in most instances and indicated that volunteer wheat can severely reduce canola yield. A model pooled over locations and years indicated that volunteer wheat populations as low as one plant m−2 reduced canola yield by approximately 1%. Yield loss predictions from the models were used to determine the economics of volunteer wheat control with herbicides. In some cases, revenue losses due to reduced canola yield could be alleviated when the value of the volunteer wheat was considered.Key words: Volunteer wheat, canola, rectangular hyperbola, multiple regression, economic threshold, volunteer cereals

A field experiment was conducted in Kanan region, province of Diyala, Iraq during the winter season 2016-2017 to screen herbicides for wheat cultivation. Six herbicides viz., Salix, Cronus, Pallas, Granstar, Topic and Atlantis were sprayed as post-emergence with second irrigation 54 days after crop sowing. Wheat growth parameters viz Crop height, Spike length and number of grains per spike were a higher in Granstar&Topic (105.2 cm, 12.6 cm, 51.4) respectively, 1000 grain weight were noted with Atlantis (40.9 g). followed by Granstar&Topic (39.2 g), Number of plants / m2 was a higher in Atlantis (430), Grain yield g \ acre was significantly increased in Granstar&Topic (1848 g) weeds growth parameters like Number of weeds / m2, Dry weight of weeds g, Weed control % and Weeds inhibition % were lower in Salix&cronos (0.0,0.0 g,100%,100%) respectively.

A field experiment was conducted to study the effect of different weed control practices on weed dyanamics, nutrient uptake and yield of wheat (Triticum aestivum L.) in rabi seasons of 2010-11 and 2011-12 at Crop Research Centre of SVPUAandT, Meerut. The treatments comprising pre-emergence application of pendimethalin @ 1000 g/ha, post emergence application of isoproturon @1200 g/ha, isoproturon+2,4-D @ 1200+600 g/ha, isoproturon+metsulfuron methyl @ 1200+4 g/ha, fenoxaprop -p-ethyl @ 80 g/ha, fenoxa prop -p-ethyl +2,4-D @ 80+600 g/ha, fenoxa prop -p-ethyl +metsulfuron methyl @ 80+4 g/ha, clodinafop propargyl @ 60 g/ha, clodinafop propargyl+2,4-D @ 60+600 g/ha and clodinafop propargyl+metsulfuron methyl @ 60+4 g/ha were tested with weed free and weedy check. Among the herbicides, application of clodinafop propargyl+ metsulfuron (60+4 g/ha) though statistically on par with clodinafop propargyl+ 2,4-D (60+600 g/ha) reduced the weed population significantly than weedy check (97.2%), clodinafop propargyl alone (88.0%), fenoxaprop -p-ethyl alone (83.0%), isoproturon alone (80.0%), isoproturon+metsulfuron (72.2%), pendimethalin (71.4%), isoproturon+2,4-D (53.8%), fenoxa prop -p-ethyl +2,4-D (53.8%) and fenoxa prop -p-ethyl + metsulfuron (40.0%) at 60 days after sowing stage. Among the herbicides, application of Clodinafop propargyl+ metsulfuron methyl (60+4 g/ha) as post emergence resulted into highest grain yield of wheat (49.28q/ha) which was on par with weed free and clodinafop propargyl+2,4-D @ 60+600 g/ha but statistically significant than rest of the treatments. Highest NPK uptake by grain and straw of wheat was recorded in weed free conditions compared to the herbicidal treatments, except lodinafop propargyl+metsulfuron methyl and clodinafop propargyl+ 2, 4-D. Highest removal of NPK (63.6 kg/ha) by weeds was recorded in weedy check whereas, the minimum NPK uptake (28.4 kg/ha) was noticed with the application of clodinafop propargyl+metsulfuron methyl due to efficient control of weeds (weed control efficiency 84.7%), which resulted in lowest weed dry matter in this treatments.

Increased crop competitiveness may complement existing weed control methods. The objective of this research was to establish whether spring wheat (Triticum aestivum L.) genotypes with contrasting competitive abilities respond differently to weed control levels. Four sibling genotypes differing in competitive ability were grown under simulated weedy conditions and subjected to four weed control levels. The competitive genotypes were superior to the less-competitive genotypes in grain yield under weedy and partially weedy conditions.

Soft White Spring Wheat

Field experiments were conducted over four growing seasons in southern Alberta to develop improved irrigation and nitrogen fertilizer recommendations for soft white spring wheat (Triticum aestivum L.). Irrigation to provide available water in the root zone to maturity maintained acceptably low protein content of soft wheat fertilizer-N plus soil test NO3-N levels from 140 to 208 kg ha−1. Nitrogen fertilizer increased protein content in all 4 yr of the study and increased yields each year except 1981 when the soil contained a high level of NO3-N. The protein content was not raised above the level considered acceptable for the domestic Canadian market (10.5%, moist basis) unless fertilizer rates in excess of the economic optimum level were applied. Fertilizer-N response curves were developed for each cultivar, irrigation treatment, and year combination. These were used to show the relationship between yield and the level of fertilizer N plus soil NO3-N which would result in economic optimum yields of soft white spring wheat of acceptable protein content. The results suggest N rates can be increased about 30 kg ha−1 for each t ha−1 increase in the target yield of the producer.Key words: Wheat (soft white spring), Triticum aestivum L., irrigation, nitrogen fertilizer, protein, target yield
