Answer:
Explanation:
1. The first step before growing a crop plant is the preparation of soil for sowing of seeds, the soil has to be loosened so that the roots of plants may penetrate deep into the soil, the loosening of soil allow the roots to breathe easily because loosened soil promotes growth of organisms like earthworms and microbes.
2. Take a beaker or mug filled with water in it.
Put all the seeds on the cup of water.
Let all the seeds to settle down.
The seeds which settles down are the healthy seeds.
And the seeds that floats on the water are spoil or damaged as they are porous and defected.
3. Farmers dump plant and animal wastes in pits at open places and allow them to decompose. The decomposition is caused by some micro-organisms. Over a period of time, the decomposed matter converts into manure.

4.Crop rotation is the practice of growing a series of different types of crops in the same area across a sequenced of growing seasons. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pest and weeds.
5.Water is one of the most important inputs essential for the production of crops. Plants need it continuously during their life and in huge quantities. It profoundly influences photosynthesis, respiration, absorption, translocation and utilization of mineral nutrients, and cell division besides some other processes.
