Answer 1

Hint: The artificial application of water for the purpose of supplying moisture essential to plant growth is called irrigation. There are various methods of irrigating crops (including both traditional and modern). Dhekli, moat, etc. are traditional types, while drip irrigation is included in modern types of irrigation.

Complete step by step answer: Irrigation is very crucial for crops. It is practised by the farmers in areas where the rainfall is very uncertain. Chain pump irrigation is a type of irrigation that consists of two large wheels which are connected by an endless chain and the buckets are attached to it, the bucket empties the water in the field and from there, it is supplied to the field. Different areas opt for different irrigation methods according to their convenience; they are.
i) Dhekli method is one of the oldest methods used in rural areas. It consists of a rope through which a container is attached, and this container goes inside the well and loads water inside it and then it is pulled manually to water the crops.
ii) Moat: It is also an old and traditional method of irrigation in which water is pulled from the well with the help of animals like cow, buffalo, ox, etc.
3) Drip irrigation: it is the most efficient method of irrigation. It involves the discharge of water through pipes which are buried inside the soil, so it saves water as it reduces the chance of unnecessary evaporation.
Hence, the correct answer is option A.

Note: Drip irrigation method was developed by Israel. It is a very efficient method not for irrigation but also for placing fertilizers and herbicides. Herbicides and fertilizers are applied to crops by solubilizing them into the irrigation water called herbigation and fertigation respectively.
