Is there any sowing and harvest inter cropping Implements.(for example Implement cultivated Sorghum and soybean in same time as well as Implement use to harvest them. )
The rotation and intercropping of legumes can have a positive effect on issues of soil impoverishment and also improves the ratios and diets of animals and humans. Under your South Sudan conditions, moisture can be the most limiting factor. Because of this in limiting moist situation crops like cowpea and peanut might be better options. Soybean has fairly high moisture requirements in comparison. In terms of cereal component maize sorghum and millet show increasing ability to deal with periodic drought issues. If you are growing sorghum for intercropping the ability to get good legume results using dwarf sorghum varieties as not to shade out the legume component. In mechanical planting planters which are based on 1 2 and 4 rows would be common depending on your ability to generate traction. Under mechanical planting conditions, alternate rows or boxes are planted with legume and sorghum. Whether you are using machine and/or hand harvest this will facilitate harvest and processing. In machine harvest the large size difference of the sorghum and soybean seed will allow crop separation by sieving. If I would make a recommendation plant in 90 cm row difference and alternate dwarf sorghum and cowpea. In for moisture limiting environment pigeon pea work with millet using the same one to one crop intercropping. Millet will give a crop much before the pigeon pea which will spread out labor and processing efforts.
to optimize your sorghum component you will need 40 days of initial weed control. if you plant with row equipment you can cultivate for organic production. For the legume component pigeon pea or peanut can be used with pigeon pea especially requiring a longer weed free period because of the extended crop season. The use of these legumes will reduce issues with witchweed. There is a push pull intercropping system using desmodium as an intercropped legume and ddsurrding the field with elephant grass. The elephant grass is not a good host for stalk boring worms and the desmodium repels the moths and is not a host for witchweed. For your sorghum or millet intercropping the use of a perimeter of elephant grass would be useful and also provides animal fodder for corraled animals.
I think that Japanese were the most modern civilization in this. Try to browse TABATA machines on the web.... good luck !!
