Abstract

Sustainable agriculture relies on fertilizers as they increase crop output; yet, their proper use is absolutely essential to reduce environmental pollution. From 2022 to 2024, a field experiment was conducted to evaluate the effect of different fertilizers on the growth and yield of Wheat (Triticum aestivum L). cultivated in a field in Kurukshetra, Haryana, India. The experiment was conducted in a randomized block design with 15 treatments and each with three replicates. The highest growth and yield parameters were recorded in plots treated with organomineral made by -50% recommended dose of fertilizers (RDF) + Composted Pond slurry (9 tons/ha) + Azotobacter (4 kg/ha), followed by treatments having Farmyard manure (8 tons/ha) + Poultry manure (8 tons/ha) + Composted Pond slurry (8 tons/ha) + Azotobacter (4 kg/ha) and recommended dose of mineral fertilizers. Organic and organomineral fertilizers positively influenced soil physical properties, resulting in higher nutrient release and improved biological properties. On the other hand, mineral fertilizer applications affect the physicochemical and biological properties of the soil. The study concluded that organomineral fertilizers strengthen the growth and yield attributes of the crops, with the organic fraction of mixed fertilizers being beneficial for soil health.
