    Treating the soil with balanced and appropriate fertilizers is vital for obtaining optimum yield and maintaining soil health in a sustainable manner. One of the bottlenecks to sustainable agricultural production is soil depletion due to unbalanced fertilization. To overcome these problems, a pot experiment was carried out, to explore the potential of composts and mineral fertilizers on the soil health, yield and NPK uptake in wheat in calcareous soil. NPK were supplemented through different sources including T1: Control, T2: 100% NPK as compost I (CI), T3: 100% NPK as compost II (CII), T4: 50%NPK each as CI and mineral fertilizers, T5: 50%NPK each as CII and mineral fertilizers, T6: 100% NPK as mineral fertilizers (120: 90: 60 kg ha-1). Significantly taller plants of (92.6 cm), higher spike length (11.60 cm), thousand grain weight (47.54 g), biological yields (9706.2 kg ha-1) and grain yield (4070 kg ha-2) were recorded at T5. Similarly, maximum leaves N content (1.54%) and P content (0.19%), soil mineral N (192.8 kg ha-1), nitrogen use efficiency (36.1 higher over control) and minimum soil pH (7.76) were also recorded were also observed at in pots treated with (50% NPK each as CII and mineral fertilizers) while the organic matter was highest in pots treated with full dose of CI. Therefore, application of NPK 50% each as mineral fertilizers and compost (CII) is recommended for obtaining optimum crop yield and improved soil and crop quality under calcareous soils.

    Drought stress adversely affects plant growth, development, and yield. It can decrease seed germination, biomass accumulation, root proliferation, chlorophyll contents, and stomatal conductance. To overcome this critical issue, researchers suggest employing environmentally friendly approaches. The exogenous application of alanine (AL) acts as an osmolyte, which helps balance the cellular water under drought stress. It can also improve root architecture, biomass accumulation, and plant fertilizer use efficiency. Applying biochar can improve soil structure, water, and nutrient retention in soil, which are allied factors in enhancing plant growth under drought stress. Furthermore, the enrichment of potassium (K) in biochar also increases its availability to plants, directly regulating the stomatal conductance to alleviate drought stress. That's why the current study aims to explore the combined effect of AL and potassium-enriched biochar (KBC) on fenugreek cultivated under drought stress. Four levels of AL (control, 2mM, 4mM, and 6mM) were applied with 0%, 1%, and 2% KBC in three replicates. Results showed that 2mM AL + 2%KBC showed significant improvement in plant length (5.24%), plant fresh weight (25.36%), plant dry weight (16.23%), chlorophyll a (7.80%), chlorophyll b (15.83%), total chlorophyll (10.65%) over the control under drought stress. A significant increase in shoot N, P, and K concentration compared to control under drought stress also validated the effectiveness of 2mM AL + 2%KBC. In conclusion, 2mM AL + 2%KBC is an effective amendment for alleviating drought stress in fenugreeks. Under drought stress, growers are recommended to apply 2mM AL + 2%KBC to achieve better fenugreek growth.

    Nano-Priming as Seed Priming Technology for Sustainable Agriculture
    (Apple Academic Press, 2025-02-21) Fatih Çiğ; Rojin Özek; Murat Erman; Sipan Soysal; Özge Uçar; Zeki Erden; Mustafa Ceritoğlu; Çağdaş Can Toprak; Sönmez Özbey; Muhammad A. Raza; Javeed A. Lone; Saifullah Abro; Muhammad Arshad; Mehmet Efe
    Agriculture is threatened by climate change and by the depletion of resources and biodiversity. Exploring new farming methods is needed to increase crop production and ensure food quality and safety in a sustainable way. Nanotechnology is an emerging trend that contributes to sustaining agricultural production. Seed nano-priming helps improve seed germination, seedling emergence, growth, and yield by resisting various plant stresses. Nano-priming is a more effective method than any other seed preparation method. Studies have shown several benefits of using seed nano-priming. By regulating biochemical pathways and the balance between reactive oxygen species and plant growth hormones, nano-priming helps increase resistance against stresses and diseases with the limited use of pesticides and fertilizers.Moreover, nano-priming prevents the continued damage caused by conventional agriculture, resulting in an environmentally safer system for farmers and consumers. The present review provides an overview of developments in the field, showing the challenges and possibilities of using nanotechnology in seed nano-priming to contribute to sustainable farming practices.

    Organic weed management can improve rice-maize rotation performances under conservation agriculture
    (Pakistan Journal of Botany, 2024-11-14) Subhra Sahoo; Dhirendra Kumar Roy; Shivani Ranjan; Sumit Sow; Smruti Ranjan Padhan; Alaa Baazeem; Omer Konuşkan; Zeki Erden; Çağdaş Can Toprak; Ayman El Sabagh
    A two-year field experiment was carried out to ascertain the influence of organic weed management (OWM) on the crop performance and productivity of rice–maize rotation under conservation agriculture. The experiment comprised of four tillage practices as main plots and five OWM treatments as subplots arranged in split-plot design with three replication. The tillage management treatments included ZTR fb ZTM: zero-tillage (ZT) direct seeded rice (DSR) followed by (fb) ZT-maize, PBDSR+R fb PBDSM+R: DSR fb maize both in permanent bed (PB) with residue incorporation, PBDSR-R fb PBDSM-R: DSR fb maize both in PB without residue and CTR fb CTM: conventionally tilled rice fb maize. In OWM, five treatments were as follows: UC: unweeded weed control, VM: vermicompost mulching, PVM: phosphorous (P) enriched VM, LM: live-mulch of Sesbania spp. in rice and Pisum sativum in maize, WF: weed-free check. The PBDSR+R fb PBDSM+R obtained a significantly higher plant height (18.9–19.7%), leaf area index (LAI) (24.0–24.6%), dry matter accumulation (DMA) (10.8– 11.3%) and crop growth rate (CGR) over CTR fb CTM in both rice and maize in all the growth stages. Moreover, PBDSR+R fb PBDSM+R recorded significantly higher grain yield (63.6 and 66.0 q ha-1) in rice and in maize (93.02 and 94.31 q ha-1) over other treatments in both years. Among the various OWM, LM reported significantly superior growth attributes viz. plant height, number of tillers m-2, leaf area index and dry matter accumulation in rice and maize and grain yield by 12.3–16% in rice and 7.4–8.5% in maize over VM across the years of study. The PBDSR+R fb PBDSM+R recorded and LM recorded significantly the highest net return and benefit-cost ratio throughout the study. The study highlights that residue incorporation under rice–maize rotation in PB led CA system along with LM enhanced productivity and profitability.
