Improvement in Food Resources

River lift systems

River lift systems directly draw water from rivers using pumps to supply irrigation in areas close to rivers. This method is used when canal flow is insufficient or irregular. Canal systems receive water from reservoirs or rivers but distribute through a network of canals. Tank systems store rainwater runoff in small reservoirs. Well systems (dug wells and tube wells) extract groundwater from underground water-bearing layers.

Better utilization of nutrients and pest control

Intercropping involves growing two or more crops simultaneously in definite patterns (alternating rows). The main advantages are: 1) Different crops have different nutrient requirements, ensuring maximum utilization of soil nutrients, 2) Prevents pests and diseases from spreading to all plants of one crop, 3) Provides insurance against crop failure, 4) Increases overall productivity per unit area. Examples include soybean + maize or finger millet + cowpea. This method is more efficient than growing single crops.

Xanthium (gokhrou)

Weeds are unwanted plants that grow in cultivated fields and compete with crops for nutrients, space, light, and water. Xanthium (gokhrou) is a common weed mentioned in the chapter, along with Parthenium (gajar ghas) and Cyperinus rotundus (motha). These plants reduce crop growth and yield by taking up valuable resources. Wheat, rice, and maize are important food crops, not weeds. Effective weed control is essential for good harvest.

Milk production and farm labour

In India, cattle farming serves two primary purposes: 1) Milk production - female cattle (milch animals) like cows and buffaloes produce milk for dairy products, 2) Draught labour - cattle are used for agricultural work such as tilling fields, irrigation, and carting. Indian cattle include Bos indicus (cows) and Bos bubalus (buffaloes). While cattle may provide other products, the main traditional purposes in Indian agriculture are milk and farm work assistance.
