Sowing Dates

A field experiment was conducted to study the effect of sowing dates and weed management practices on weed growth and nutrients depletion by weeds and uptake by wheat. The results revealed that crop sown on 15th November significantly reduced the weed density and its dry matter was compared to crop sown on 25th December. Among weed management treatments, ready mix application of sulfosulfuron + metsulfuron at 30 g/ha + 2 g/ha followed by metribuzin (210 g/ha) showed significantly lowest density and dry weight of weeds. Wheat crop sown on 15th November showed significantly lowest nutrient depletion by weeds and highest yield, nutrients uptake by wheat crop. Significantly lowest nutrient depletion by weeds, highest growth parameters, yield attributes, yield and nutrient uptake by wheat crop were recorded with the ready mix application of sulfosulfuron + metsulfuron at 30 g/ha + 2 g/ha. Regression equation revealed that unit increase in the weed control efficiency increased the grain yield by 25.56 kg/ha. Bangladesh J. Bot. 50(2): 311-318, 2021 (June)

Long-term field trials are essential for monitoring the effects of sustainable land management strategies for adaptation and mitigation to climate change. The influence of more than thirty years of different management is analyzed on extensive crops under three tillage systems, conventional tillage (CT), minimum tillage (MT), and no-tillage (NT), and with two crop rotations, monoculture winter-wheat (Triticum aestivum L.) and wheat-vetch (Triticum aestivum L.-Vicia sativa L.), widely present in the center of Spain. The soil under NT experienced the largest change in organic carbon (SOC) sequestration, macroaggregate stability, and bulk density. In the MT and NT treatments, SOC content was still increasing after 32 years, being 26.5 and 32.2 Mg ha−1, respectively, compared to 20.8 Mg ha−1 in CT. The SOC stratification (ratio of SOC at the topsoil/SOC at the layer underneath), an indicator of soil conservation, increased with decreasing tillage intensity (2.32, 1.36, and 1.01 for NT, MT, and CT respectively). Tillage intensity affected the majority of soil parameters, except the water stable aggregates, infiltration, and porosity. The NT treatment increased available water, but only in monocropping. More water was retained at the permanent wilting point in NT treatments, which can be a disadvantage in dry periods of these edaphoclimatic conditions.

Abstract To study the effect of sodium Selenite application different methods on the yield of spring wheat varieties, depending on the conditions of water supply, a series of vegetation experiments in accordance with the methodology were carried out. The object of the study is spring wheat of the Zlata variety (Triticum aestivum L.). It was found that the effect of selenium on the yield of wheat of the Zlata variety depended on the method of its application and the conditions of water supply. With optimal water supply, the positive effect of selenium on the yield of spring wheat plants was revealed with both methods of applying sodium selenite. It was found that in conditions of drought, the positive effect of selenium was obtained with both methods of using sodium selenite. The greatest efficiency of selenium is obtained in foliar processing of plants. The increase in grain weight in this variant was 1.4 times. The increase in the share of the agronomic significant part of the wheat crop yield to 36% is shown, which indicates the decrease in the negative effect of drought on the formation of spring wheat yield when using foliar processing of plants.

Sunflower (Helianthus annuus L.) is grown in rotation with wheat (Triticum aestivum L.) in the upper midwest of the U.S.A. However, volunteer sunflower is often a problem in wheat planted the year following sunflower. Wheat yields as influenced by wheat seeding date and sunflower density, duration of sunflower competition and rate of sunflower control were determined in the field. Season-long sunflower competition at densities of 3, 9, and 23 plants per square metre reduced yield of the following wheat crop by an average of 11, 19, and 33%, respectively, averaged over seeding date and location. Sunflower was more competitive with wheat seeded in late than in early May, particularly at the lower sunflower densities. Wheat yield was reduced 22% when 24 sunflower plants/m2 were allowed to compete until the wheat flag-leaf stage. Wheat yields obtained were similar when volunteer sunflower was controlled by postemergence MCPA [[(4-chloro-o-tolyl)oxy] acetic acid], bromoxynil (3,5-dibromo-4-hydroxybenzonitrile), or bromoxynil plus MCPA despite the slower rate of control with MCPA compared to bromoxynil or bromoxynil plus MCPA. This research indicates that wheat following sunflower should be planted early and sunflower densities of nine plants per square metre or higher should be removed before the flag-leaf stage to prevent yield reductions.Key words: Density, duration, bromoxynil, MCPA, Helianthus annuus, Triticum aestivum
