A review on axle torque sensing devices for energy harvesting of tractor implement combination

Agricultural machines contribute a major portion of the total cost of crop production. Proper matching of tractors and implements is crucial for maintaining high operational efficiency on the farm. If the implementation is specified, the draft will be a function of travel speed for a given soil condition and a cultivation depth. Operating costs for any given tractor or implement can be minimized by selecting an optimum...

Comparative study on agar and cassava gelled media in in-vitro propagation of ginger

Ginger is propagated vegetatively using underground rhizomes. Most farmers use planting materials saved from previous harvest. These materials could have been sold for cash. Contingent on this, many farmers are reluctant to use healthy succulent rhizomes for planting. These are rather sold thereby resulting in acute shortage of planting materials. Tissue culture technique can be applied to mass-produce seedlings for...
