Ground nut, rapeseeds and mustard, sesame, coconut, linseed, sunflower and soybean are the major oil seed crops grown in India. Irrigation of recycled wastewater is also considered as a means for plant fertilization and particularly nutrient supplementation. The flood water remained until the fertile sediment had settled before the engineers returned the surplus to the. This system was discovered in the early 1920s, when the British were constructing a canal between the rivers Ganga and Damodar. The system enables the application of water and fertilizer at an optimum rate to the plant root system. .
A drive system often found near the centre of the wheel line rotates the clamped-together pipe sections as a single axle, rolling the whole wheel line. Sugar cane Sugar cane is the major source of sugar in the country. In artesian wells, water level remains at a high-level because of the natural flow of water due to high pressure. The budgets for these systems were large, and so was the incremental produce that farmers could get by adopting such systems. A tube well cannot be constructed in all places and requires some geographical conditions favouring its installation. It is therefore a disincentive for farmers to adopt technology-intensive micro-irrigation system in the regime of power outages. The yield results as compared to traditional methods are unbelievable.
A reservoir with an area less than five bighas is called a talai, a medium sized lake is called a bandhi and bigger lakes are called sagar or samand.
