Exploitative technological the evaluation of the work breaking for cultivation bean (Phaseolus vulgaris L.)

Abstract

 This work was carried out in the UEB "Agricultural" belonging to the Paquito Rosales Benítez Miscellaneous Crops Company of the Yara Municipality, in the province of Granma. It was carried out with the objective of evaluating some technical-exploitative indicators of the Belarus-800 tractor, forming an aggregate with the ADI-3M y AFT-4 disc plows in the preparation of soil for bean cultivation, taking into account productivity by hour of clean time (WTP), per hour of operating time (W02), per productive time (W04), per hour of shift time without failures (Wt), per hour of operating time (W07) all these in (ha·h-1). Having as a result that T2 has the highest productivity values ​​for clean, operational, productive, faultless and exploitative time and the lowest fuel consumption (18.00 L·ha-1) in relation to breakage with the plow of ADI-3M with 20.00 L·ha-1, performing this the lowest working speed 5.42 km·h-1, under the same soil and weather conditions. Likewise, of the higher direct operating expense of 468.65 CUP·ha-1.
