Application : This system is basically used                Sickles  :
               in  the  desert  region  where  the  water                  crop.
               availability  is  scarce  and  rainfall  is  also

               uneven.
               (ii) Drip system :

               Design  :  It  also  consists  of  a  main  pipe
                attached  to  several  lateral  pipes.  The
                difference is in the location of nozzles on                                Sickles
                the lateral pipes, in the case of  drip system            By hands directly :
                the nozzles are located near the roots of                  are plucked by hands.
                plants.

               Working : Water is drawn by a pump to the
                main pipe.




                   Then to the lateral pipes.

                                                                                      Harvesting by hand
                                                                    (b) Harvesting through machines : Harvesting
               From the lateral pipes water is allowed to               becomes fast and easy by using specially
                fall drop-by-drop very close to the roots of
                                                                        manufactured agricultural equipments and
                the plants.
                                                                        machines.
                                                                          By  tractor  :
                                                                           attached to the tractor and then crops

                                                                           like  wheat,  paddy  can  be  harvested
                                                                           easily.




                                 Drip system

               Application : Useful for watering fruit, trees
                and gardens.

            5.  Harvesting : The process of cutting down of
            mature crops is called harvesting                                  Tractor                  Harvestor

            Methods of harvesting :                                 Threshing and winnowing : After cutting down
            (a) Manual  harvesting  :  Harvesting  can  be          of crops, the next step of harvesting  includes
                done manually by using :                            separation of grains from the crops. It can be




            Chaff is the outer part of grain such as wheat. It is removed before the gain is used for food. Stem of the crops
            together with chaff is called fodder. Fodder forms the cattle feed.
