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]
Paddy is cultivated at least twice a year in most parts of India, the two seasons being known as Rabi and Kharif respectively. The former cultivation is dependent on irrigation, while the latter depends on the Monsoon. The paddy cultivation plays a major role in socio-cultural life of rural India.
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.
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]
Nigerian Books of Record (NBR) is a reference / Official Book of Record of the Federal Republic of Nigeria for documenting good records held by Nigerians. It is a collection of human achievements categorized into education, literature, agriculture, medical science, business, sports, nature, adventure, radio and cinema etc. [ 1 ] [ 2 ]
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.
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.
