Three mathematical models were developed to describe: the efficiency of dehulling, unshelled grain and damaged grain of an experimental model to dehull the castor capsules. The model was validated with the experimental data. The variable of the model was the slack of the disc and the concave. In addition, the moisture content of the capsules was determined, with an average of 5.43%. A high cor ...

In the Central Valleys of Oaxaca, Mexico, farmers produce plants, animals and fungi in both traditional agroecosystems called milpa and highly mechanized agricultural systems. In Mexico there is a belief that highly mechanized agricultural systems are the most efficient since they have high yields of agricultural products. For this reason, an energetic analysis of both agroecosystems was carri ...

Technification and agricultural technological development have an impact on the food security of the population. The development of models that consider the use of water in crops, considering the availability of adequate water to the variation of climate and soil in the irrigation areas, are the key to mitigate the effects of a changing climate and bad practices. In the Mexican Republic, the i ...
