ABSTRACT

Bangladesh is a small country having huge population. Day by day, it is required to produce more food to meet the demand of growing population. To fulfill the demand, we have to increase crop yield by adopting the high farming techniques. Maize is one of the most important cereal crops in the country and the leading crop of the world after rice and wheat. Maize has the highest potential for carbohydrate production. In Bangladesh, it occupies 1.68 lac hectares land and produces10.38 lac metric tons with an average yield of 6.27 t/ha. In Dinajpur district maize has been planted 79,402 hectares. For increasing corn yield we have designed a machine named power operated hilling corn with double wheel hoe. Corn hiller is farming implement used to create hills or ridges of soil around corn plants. It improves water drainage and prevents erosion. It can also help to conserve moisture in dry season. Manual weeding is common in Bangladesh, but this method is labor intensive and is one of the major farming problems in Bangladesh. The additional work of the machine is to remove weeds from corn field by allowing the soil working components to penetrate into the soil and cut or uproot the weeds between the crops rows and also bury the weeds. It is a useful tool for the improvement of soil health and maximizes the corn yield. The travelling speed of the machine was found 1.75 km/hr. The theoretical field capacity was found 0.08 ha/hr and the effective field capacity was 0.067 ha/hr. The field efficiency of the machine was 83.75%. The turning loss and weeding efficiency of the machine was 15.34% and 61.58% respectively.
