Cultivators is the percentage of cultivators in the agricultural workforce (cultivators and agricultural labourers).

Irrigation is the percentage of cultivated areas which are irrigated. It does'nt inform us about the intensity of the irrigation, i.e. the number of irrigated cultures per year, knowing for example that an irrigation by tubewell makes it more possible to get rid of the climatic constraints than an irrigation by tank.
