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.
The risk of yield variability is cited as a critique as SRI methods can be more susceptible to yield variability than traditional methods of rice cultivation. This is because SRI involves more precise plant spacing and nutrient management, which can be affected by weather conditions and other factors that are difficult to control. [59]
Agricultural sustainability in Northern Nigeria requires flexibility in both ecological management as well as economic activity. [1] The population densities of the rural area in this region climbed from 243 to 348 people per square kilometer between 1962 and 1991, but the land area under permanent cultivation remained approximately the same.

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.

A water tube/pipe made of PVC is usually used to practice AWD method. The main purpose of the tube is to monitor the water depth. The tube allows measuring water availability in the field below the soil surface. The usual practice is to use a pipe of 7–10 cm diameter and 30 cm long, with perforations in bottom 20 cm.
