8. Farmers can use new implements
With animals and 8 plough the soil can be prepared better and more quickly. It is also possible to cultivate larger fields.
On a well- prepared soil the seed can be sown in rows. This makes it easier to remove weeds.
By preparing the soil, sowing in rows and weeding, yields can be greatly increased, even doubled.
9. They can apply manure and fertilizers.
Once farmers have used new tools they get a bigger harvest and more money. With the money they earn, the farmers can buy fertilizers.
If the plants are given manure or fertilizer, they will be well nourished. The harvest will be bigger, and the soil keeps its fertility. The same fields can grow crops for a longer time.
Once the farmers use new tools and also apply manure and fertilizers, they are growing upland rice by very modern methods.
10. They can protect the rice against pests.
It is difficult to keep off the rats and the birds. You can have a watchman near the field. Noise can frighten the birds away. Rice fields must be watched especially at the time when the grain begins to ripen.
There are also certain insects that damage rice, for example, rice borers, which lay their eggs on the leaves. When they grow, they eat through the stem. When the stems go white, apply BHC (benzene hexachloride) and Aldrin, a product which can kill these insects. Ask your extension service for this product.
