                       Dry land agriculture
                       Growing of crops under rainfed condition is known as dry land agriculture. Most fifty percent kpk
                       is rainfed. Depending on the amount of rainfall dry land agriculture is divided into three
                       categories. Dry farming, Dry land farming and Rainfed farming
                       Dry farming
                       Cultivation of crop in those areas where rainfall is less than 750 mm annually.
                       Dry land farming
                       Cultivation of crop in those areas where rainfall is greater than 750 mm .
                       Rainfed farming
                       Where rainfall is greater than 1100 mm.

                                                          Types of climate

                       Tropical
                       Climate is hot or temperature is high throughout the year.
                       Temperate
                       Summer is spring like while winter is freezing less than zero.
                       Subtropical
                       Summer very hot
                       Spring spring like
                       Winter is mild.
                                                       On the basis of rainfall
                       Humid
                       Rainfall is greater than 1000 mm per year.
                       Sub humid
                       That area where rainfall is between 600-1000mm.
                       Arid
                       Where rainfall is less than 250 mm.
                       E.g.  thar in cholistan, thal in miawali.
                       Semi arid
                       Subtropical like temperature
                       250 mm to 600 mm rainfall per year.

                                              Four types of barani cultivation practices.
                       1.  Rainfed cultivation
                       2.  Flood water cultivation or silabah farming
                       3.  Rod kohi
                       4.  Run off farming or khush kaha
