Weed dynamics and productivity of wheat (Triticum aestivum) under various tillage and weed management practices

The reduced yield under conventional tillage is due to more crop-weed competition and more dry matter accumulation by the weeds (Kumar et al. 2018). Due to zero weed competition, weed-free treatments yielded the highest grain yield of all weed management practices. In contrast to this, the lowest grain yield was obtained in weedy treatment due to season-long weed competition. Maximum yield under W8 is due to broadspectrum activity of these herbicides (Sharma et al. 2014, Sunil et al. 2021). The use of zero tillage reduced weed incidence and suppression, leading to higher grain yields. Therefore, zero tillage and metsulfuron 20% wp 4 g a.i./ha + clodinafop propargyl 15% wp 60 g a.i./ha should be practiced for minimizing weed growth and maximizing the yield

Assessing the Influence of Nano Urea on the Growth and Yield of Irrigated Wheat (Triticum aestivum L.) Crop

Wheat (Triticum aestivum L.) is one of the world's most essential cereal crops, serving as a staple food for a significant portion of the global population. In the pursuit of achieving higher yields in contemporary agriculture, the use of chemical fertilizers poses an increased environmental risk. However, the application of Nano urea offers a potential solution to mitigate this risk to a certain extent. To address this objective, a field experiment was conducted during the Rabi seasons of 2022-2023 at the A trial was executed in the rural area of Kanpur district of Mandhana, located 10 km from Kanpur in Uttar Pradesh, during the Rabi season of 2022-23. The experimental design involved two main factors: Factor-1 Nitrogen (at 50%, 75%, and 100% levels) and Factor-2 Foliar Spray (at one time Nano urea and two time Nano urea, with 4 ml/l). A control group was included, and the experiment was laid out in a Randomized Block Design (RBD) with 13 treatments in three replications. The results indicated that the combination of 100% nitrogen along with a foliar spray of 4 ml/L Nano urea had a significant positive impact on growth, yield, and various yield parameters. Treatment 6 demonstrated the highest values for plant height (95.66 cm), Dry matter accumulation (1014.09 g m-2), number of tillers m-2 (417.44), Leaf area index at 90 DAS (4.85), effective ear head per (m-2) (282.66), grains per ear head (65.75), test weight (48.52 g), grain yield (46.15 quintals/ha), and straw yield (57.92 quintals/ha). The study's results demonstrated a generally positive effect of combined Nano urea with traditional NPK nutrient supply on the growth and yield parameters of wheat in irrigated conditions

An Investigation into the Impacts of Preparatory Tillage and Nutrient Management on Barley Yield and Economic Viability in the Context of Water Stress Conditions

A number of field tests were carried out at the Chandra Shekhar Azad University of Agriculture and Technology's Soil Conservation and Water Management Farm in Kanpur, Uttar Pradesh, during the successive rabi seasons of 2020–21 and 2021–22. The gangatic alluvial soil in the study area had a pH of 7.6, which was indicative of its light texture and moderate soil fertility. The study included three different treatments that included preparatory tillage techniques: T1 treatment was one cross plowing with a cultivator; T2 treatment was one disc harrow plowing followed by another cross plowing with a cultivator; and T3 treatment was one disc harrow plowing plus one rotavator pass. The experiment also looked into three different nutrient management strategies: N1, which involved applying 100% of the Recommended Dose of Fertilizers (RDF)—60 kg of N, 30 kg of P2O5, and 30 kg of K2O—through chemical fertilizers; N2, which involved applying 75% of the RDF through chemical fertilizers along with 25% of Farm Yard Manure (FYM); and N3, which applied 50% of the RDF through chemical fertilizers along with 50% of FYM. In addition to applying 50% RDF through chemical fertilizers combined with 50% FYM, the results of the two-year experiment showed that planting barley crops in plots that received one disc harrow plowing and one rotavator pass yielded the maximum values across growth factors, yield attributes (such as grain yield q ha-1, straw yield q ha-1, biological yield q/ha, as well as harvest index), net return, gross return, and the barley benefit-to-cost ratio. This was noted in both years in a consistent manner. The next best results were seen with preparatory tillage, which involved using a cultivator to plough a single cross and applying chemical fertilizers to achieve 100% RDF (N1: 60 kg N ha-1 + 30 kg P2O5ha-1 + 30 kg K2Oha-1)
