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 method was developed by a French Jesuit Father Henri de Laulanié in Madagascar [1] and built upon decades of agricultural experimentation. 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 ...

A paddy field is a flooded field of arable land used for growing semiaquatic crops, most notably rice and taro.
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.
No-till farming (also known as zero tillage or direct drilling) is an agricultural technique for growing crops or pasture without disturbing the soil through tillage.No-till farming decreases the amount of soil erosion tillage causes in certain soils, especially in sandy and dry soils on sloping terrain.
A farmer and his cow. The majority of herders in African countries are livestock owners. Livestock farming is a part of Nigeria's agriculture system. In 2017, Nigeria had approximately over 80 million poultry farming, 76 million goats, 43.4 million sheep, 18.4 million cattle, 7.5 million pigs, and 1.4 million of its equivalent. [26]
It is a method of controlled and intermittent irrigation. A periodic drying and re-flooding irrigation scheduling approach is followed in which the fields are allowed to dry for few days before re-irrigation, without stressing the plants. This method reduces water demand for irrigation and greenhouse gas emissions without reducing crop yields.
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.
