Introduction
Ancient India, with its diverse agro-climatic zones, witnessed the evolution of sophisticated agricultural practices and profound botanical knowledge. This expertise, accumulated over millennia, formed the backbone of its economy and sustained large populations. From rudimentary ploughing techniques to advanced irrigation systems, and from systematic crop rotation to deep understanding of plant pathology and classification, ancient Indian agriculture and botany were characterized by innovation, sustainability, and a scientific temper, often documented in comprehensive treatises. This rich heritage continues to offer insights into ecological balance and resource management.
Ancient Agricultural Practices
Ancient Indian agriculture evolved significantly from the Harappan period to the medieval era, incorporating diverse techniques suited to varying geographical and climatic conditions.
Plough
- Early Evidence: The earliest evidence of a ploughed field comes from Kalibangan (Harappan Civilization), Rajasthan, dating back to c. 2800 BCE. Terracotta models of ploughs have been found at sites like Banawali (Harappan).
- Vedic Period: The Rig Veda mentions the use of a plough (sira) drawn by oxen. Later Vedic texts like Yajurveda and Atharvaveda detail ploughing, sowing, and harvesting. Initially, wooden ploughs were common.
- Iron Ploughshare: The introduction of iron ploughshares around 1000 BCE (Later Vedic period) significantly boosted agricultural productivity, particularly in the fertile Ganges valley by allowing clearing of dense forests and tilling of hard soil.
Crop Rotation
- Though not explicitly termed "crop rotation" in modern scientific sense, ancient Indian farmers intuitively understood the benefits of varying crops.
- Principle: They practiced intercropping, mixed cropping, and sequential cropping to maintain soil fertility, control pests, and ensure a stable yield. For instance, growing leguminous crops (pulses) after cereals was a common practice to restore nitrogen in the soil.
- Benefits: Reduced soil exhaustion, improved nutrient cycling, reduced pest and disease incidence, and enhanced overall productivity.
Irrigation
- Harappan Period: Evidence of large reservoirs and dams at Dholavira for water harvesting and irrigation. Canals are less evident but might have existed.
- Mauryan Period: Kautilya's Arthashastra describes state control over water resources, construction of dams, canals, and wells, and levying irrigation taxes (udakabhaga). The Sudarshan Lake in Girnar, Gujarat, constructed during the Mauryan period and repaired by Rudradaman I, is a prime example.
- Gupta & Post-Gupta: Continued development of tank irrigation (especially in South India, e.g., Kaveri delta), wells, and artha-kupas (draw-wells). The Pallavas and Cholas were known for extensive tank irrigation systems.
- Methods: Wells (public and private), tanks (rain-fed reservoirs), canals (diversion channels from rivers), and small dams/embankments.
Knowledge of Seasons
- Ancient Indian farmers possessed sophisticated knowledge of meteorology and astronomical cycles.
- Monsoon Dependence: Agriculture was heavily dependent on the monsoon, leading to detailed observations of clouds, winds, and celestial positions for rain prognostication.
- Cropping Seasons: The concept of Kharif (monsoon/autumn crops like rice, millets) and Rabi (winter/spring crops like wheat, barley) seasons was well-established, guiding sowing and harvesting times.
- Panchangas: Traditional calendars provided detailed information on auspicious times for agricultural activities, linked to planetary positions and seasonal changes.
Variety of Crops
- Food Grains: Wheat, Barley (earliest cultivated cereals), Rice (evidence from Lothal, Rangpur), Jowar, Bajra, Millets.
- Pulses: Lentil, Chickpea, Moong, Urad, Arhar.
- Oilseeds: Sesame, Linseed, Mustard.
- Cash Crops: Cotton (Harappan Civilization), Sugarcane, Indigo, Opium.
- Vegetables & Fruits: A wide range of vegetables (gourds, roots) and fruits (mango, banana, pomegranate, grapes) were cultivated.
- Spices: Pepper, cardamom, ginger, turmeric.
