Explanation

Neem (Azadirachta indica) is a major source of azadirachtin, a plant-derived biopesticide that disrupts insect feeding, growth and reproduction, and is widely promoted as an eco-friendly pesticide [1]. Various neem by-products, notably neem seed cake and residues, are used as organic amendments and biofertilizers to improve soil fertility and crop yields in integrated farming systems [2]. Neem has also been reported to possess spermicidal and anti-fertility properties and related bioactive compounds have been investigated for contraceptive uses, giving it relevance as an anti‑fertility source in industrial applications. Additionally, neem derivatives (e.g., neem-coated urea) reduce nitrogen leaching and improve nutrient use efficiency, reinforcing its fertilizer-related industrial role [3].
