Abstract: Weed control is the most difficult task on an agricultural farm. Three methods of weed control are commonly known in agriculture. They are mechanical, chemical and biological. Mechanical weed control is easily adopted by farmers once they get convinced of its advantage. Various types of mechanical weeders have been developed. This project is involved in construction and evaluation of integrated secondary tillage implement for harrowing after discovering that tools such as, traditional plow, spike tooth harrow, hoes require high drudgery, time consuming and high labor force with poor efficiency, used for preparation of seed bed before plantation. As a solution of this problem, mechanical integrated secondary tillage implement for harrowing is developed. This implement is made by integrating cultivator and spike tooth attached back and forth on trapezoidal frame. The cultivators cut the soil and uproot the weed roots, and the spike tooth harrow, pulverizes the soil and collects the uprooted weed roots. The developed integrated harrowing implement was tested on the primarily tilled field and the relevant data were collected and collected and statically analyzed. The field efficiency of the implement was 0.78% and has field capacity of 0.043 ha/hr. for clay soil. Thus, based on performance indicator taken to evaluate the treatments it can be concluded that the developed ISTI (integrated secondary tillage implement) has shown good result as compared to that of traditional plow.

Abstract: Threshing is a key part of agriculture that involves removing the seeds or grain from plants from the plant stalk. In most threshing operations the next steps are separation and cleaning seeds from material other than grains. The operation of separation refers to separating threshed grains from bulk plant material such as straw. Most of the topography of the western Oromia farm lands is not affordable for hiring combine harvesters. Nowadays, Different research centers including regional and federal have been manufacturing different models of stationary multi crop threshers. Even though, an effort made to develop and manufacture multi crop thresher is so encouraging most of can’t thresh efficiently more than two crop types. The performance of the multi crop thresher was tested at three different drum speeds of (DS1= 750, DS2 = 800 and DS3= 850 rpm and DS1= 480, DS2 = 530 and DS3= 580 rpm), three different feed rates of the crop (FR1 = 1250, FR2 = 2500 and FR3 = 3745 kg/hr. and FR1 = 915, FR2 = 1830 and FR3 = 2745 kg/hr) for wheat and maize crop respectively. Threshing capacity, threshing efficiency, cleaning efficiency and grain loss for wheat crop and shelling capacity, shelling efficiency, cleaning efficiency and mechanical damage for maize crop of the prototype machine were monitored at different drum speeds and feed rates. The maximum threshing capacity of 2066.01 kg/hr was observed at drum speed of 800 rpm and feeding rate of 3750 kg/hr. The maximum shelling capacity of 1817.4 kg/hr was observed at drum speed of 530 rpm and feeding rate of 2745 kg/hr followed by 1803.4 kg/hr at 480 rpm with the same feeding rate.
