CROP STRUCTURE Crop structure Jack is an application software developer recently he has been assigned to a new project for crop management by the government. Actually, his task is to develop an app which will maintain the crop details like required rainfall, the temperature suitable for the growth of the plant, sow date, and harvest date. The Government would need to plan the budget for crops during the start of the financial year, for which required water quantity, pesticide, infrastructure to maintain temperature all are factors that affect harvest date of a crop. So help Jack in building filters by temperature and rainfall and sort the crops by sow date, harvest date. This will help the government to plan budget according to the sow and harvest date.

Crop Rotation Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in sequenced seasons. It is done so that the soil of farms is not used for only one set of nutrients. It helps in reducing soil erosion and increases soil fertility and crop yield. In crop rotation technique, there are four strategies. Out of those, 1) Two field system 2) Three field system are popularly followed. Two Field System: Under a two-field rotation, half the land was planted in a year, while the other half lay fallow. Then, in the next year, the two fields were reversed. Three-field system: Dividing available lands into three parts. One section was planted in the autumn with rye or winter wheat, followed by spring oats or barley; the second section grew crops such as peas, lentils, or beans; and the third field was left fallow. The three fields were rotated in this manner so that every three years, a field would rest and...
