| Title : | ENERGY USE IN MECHANIZED PRODUCTION OF SILAGE |
| Abstract : | The paper presents the results of tests of machines in silage corn. The experiments were carried out under production conditions in 2012/2013 on the farm of the family Cunmuljaj in the village of Podhum, Tuzi, the periphery of Podgorica in Montenegro. The main objective was the assessment of the optimal parameters of productivity, work quality, and energy consumption in manufacturing and storing of silage. Working speed of the machine and tractors aggregate (TMA) was studied; its productivity, as well as energy and fuel consumption. To review the effectiveness of the various tests chronometric method was applied. Hand-held stopwatch was used for the speed measuring of the individual farming operations: basic tillage, application of mineral fertilizers, supplemental tillage, sowing, cultivation of crops, weed control and plant disease, irrigation, silage of plant mass, transport of silage mass and compaction of silage. Sowing of corn silage is done with the tractor aggregate (P=28kW), with the row spacing between the plants of 70cm; the distance 18 cm; 75000 plants per hectare, with the average of 28 l ha-1; energy consumption of 1148 MJ ha-1. In the tillage the diesel fuel consumption amounted of 12.8 l ha-1, 524.8 MJ ha-1 respectively. With the application of mineral fertilizers, the average consumption of diesel fuel stood at 0.55 l ha-1; 22.55 MJ ha-1 respectively. The highest consumption of diesel fuel was achieved with the ensiling of plant mass, which was in average 88.6 l ha-1, which represents the energy consumption of 3632 MJ ha-1. The total consumption of diesel fuel amounted 213 l ha-1; 8741.2 MJ ha-1, with the yield of 66.840 kg ha-1, and the energy value of 374 304 MJ. |
