🔆 Allelopathy in Irrigated Cropping Systems
📍 What is Allelopathy?
✅ Allelopathy is a biological phenomenon where plants release biochemicals (allelochemicals) that influence the germination, growth, survival, or reproduction of nearby organisms.
📍 Role in Cropping Systems
✅ Helps in weed control by releasing allelochemicals from leaves, roots, seeds, or stems.
✅ Supports natural herbicide development — eco-friendly compared to synthetic chemicals.
✅ Can improve crop yield and replanting success (e.g., in rice-wheat systems).
✅ Reduces soil sickness and autotoxicity when managed scientifically.
✅ Used in straw mulching for sustainable agriculture.
✅ Promotes low phytotoxic residue in water and soil — supports water recycling and treatment.
📍 Significance
✅ Offers eco-friendly weed management in irrigated zones.
✅ Reduces dependency on chemical herbicides.
✅ Aligns with sustainable agriculture and climate-resilient farming goals.
✅ Enhances crop protection and agronomic efficiency.
📍 Conclusion
✅ Allelopathy is a sustainable and innovative tool for addressing the challenges of food security, chemical-free farming, and crop health in major irrigated cropping systems.

🔆 Key Facts About Pulses in India 🌾
📍About Pulses
✅ Edible seeds of leguminous plants (Fabaceae).
✅ High in protein, fiber, nutrients, low in fat.
✅ Nitrogen-fixing → improves soil fertility.
✅ Long shelf life when dried.
📍Climatic Needs
✅ Temp: 20–27°C, Rainfall: 25–60 cm, Sandy-loamy soils.
✅ Rabi Pulses (60%) – Gram/Chana, Masoor → need mild cold.
✅ Kharif Pulses – Moong, Urad, Arhar → need warm climate.
📍India’s Production
✅ Largest producer (25%), consumer (27%), importer (14%) globally.
✅ Top states: Madhya Pradesh, Maharashtra, Rajasthan, UP, Karnataka.
✅ Pulses = 20% of grain area but only 7–10% output.
✅ Gram dominant (40%), followed by Tur (15–20%), Urad & Moong (8–10%).
📍Imports (2024-25)
✅ Record imports: 7.3 mt, USD 5.5 bn.
✅ Sources: Canada, Russia, Australia, Mozambique, Tanzania, Myanmar, US.
✅ Imports spiked due to El Niño drought → output fell to 24.2 mt (2023-24), partly recovered to 25.2 mt.
📍Challenges
✅ MSP bias towards rice/wheat; weak procurement of pulses.
✅ Climate vulnerability (rainfed, drought/monsoon shocks).
✅ Low productivity: 660 kg/ha vs world avg 909 kg/ha.
✅ Small holdings, poor R&D, soil & pest issues.
✅ High post-harvest losses (5–10%).
📍Govt Initiatives
✅ NFSM-Pulses, PM-AASHA, NMSA, RKVY, Mission on HY Seeds.
📍Way Forward
✅ Promote HYVs & biofortified varieties (iron-rich lentils, pigeon pea hybrids).
✅ Expand micro-irrigation, rice-fallow pulses, precision farming.
✅ Reform MSP/procurement, rebalance subsidies, incentivize diversification.
✅ Strengthen storage, processing, FPO linkages.
✅ Boost R&D + extension services (KVKs, IPM, intercropping).
✅ Maintain 2.5–3 mt buffer stock, regulate imports dynamically.
📍Conclusion
✅ India must tackle policy bias, climate risks, and import dependence.
✅ With reforms, R&D, procurement & storage, pulses can ensure farmer incomes + food security.
