A. Sowing of seeds: One of the important parts of crop production is sowing. Good quality seeds are selected and are sown in prepared soil with the help of various tools like traditional tools and seed drill.
Tradition tools: The shape of this tool is like a funnel which is filled with seeds, then the seeds are passed down through two or three pipes having sharp ends and these ends pierce into the soil and place seeds there.
Seed drill: Nowadays, a traditional tool has been replaced by seed drill. This tool is used for sowing with the help of tractors and it sows the seeds uniformly and at proper distances and depth, it also ensures covering of the seeds from soil after sowing, so that seeds could not get damaged by birds and by other organisms. Sowing by using a seed drill saves times and labour.
B. Threshing: In the harvested crops, the grain seeds are separated from the chaff, this process is called as threshing, this is carried out with the help of the machine called as a 'combine' which works as harvester and thresher both.
