Paddy cultivation should not be confused with cultivation of deepwater rice, which is grown in flooded conditions with water more than 50 cm (20 in) deep for at least a month. Global paddies' emissions account for at least 10% of global methane emissions. Drip irrigation systems have been proposed as a possible environmental and commercial ...
Puddling is the tillage of rice paddies while flooded, an ancient practice that is used to prepare for rice cultivation. Historically, this has been accomplished by dragging a weighted harrow across a flooded paddy field behind a buffalo or ox, and is now accomplished using mechanized approaches, often using a two-wheel tractor.
The practice is beneficial as it yields harvests of both rice and ducks. The two are in addition synergistic , as the rice benefits from being weeded and fertilized by the ducks, and having pests removed, while the ducks benefit from the food available in the rice paddy fields , including weeds and small animals.
Subak is the water management (irrigation) system for the paddy fields on Bali island, Indonesia.It was developed in the 9th century.For the Balinese, irrigation is not simply providing water for the plant's roots, but water is used to construct a complex, pulsed artificial ecosystem [1] that is at the same time autonomous and interdependent.

Direct seeded rice (DSR) [2] [3] is a practice of sowing paddy which involves planting rice seeds directly into the field, instead of the traditional method of growing seedlings in nurseries and then transplanting them into the fields. This method significantly reduces the demand for labor, one of the major costs associated with rice farming.
SRI focuses on changing the management of plants, soil, water, and nutrients to create a more productive and sustainable system of rice cultivation. [2] A comparison of SRI grown rice to conventional methods. The methodology has been adopted by millions of smallholder farmers around the world, particularly in Asia and Africa.
The term “upland rice” refers to rice cultivated in non-flooded conditions, and it can encompass various specific definitions. While most of the world's rice is grown in paddy fields or wet environments that require significant amount of water, rice itself does not inherently need flooding to thrive.
Alternate wetting and drying (AWD) is a water management technique, practiced to cultivate irrigated lowland rice with much less water than the usual system of maintaining continuous standing water in the crop field. It is a method of controlled and intermittent irrigation.
