Summary: Recently an increasing application of power harrow in
secondarytillage is apparent.Measurements show that power requirement
inrelation to peripheral velocity of harrow tines is of linear
typedependence.It is also found that optimal quality of work could
beachived selecting proper combination of working speed,workingdepth and
peripheral velocity of harrow tines.Statisticalanalysis shows that there
are 6 equal combinations of v and hthat achive equal work evaluated by
means of weight diameter ofclods.The best one is v3 h1 u3 with regard to
energy requirementas well as to field effect.This combination in comparison
withalternative v2 h1 u3 requires 18.0% less energy and gives 47.0%higher
field effect.

Summary: Six various systems of tillage were tested in wheat
production insame working conditions.The aim was to compare energy and
labourrequirements for each system.Conventional system was comparedwith
five systems of reduced tillage.Results indicate thattillage with one pass
of rotary cultivator could be a promissingsolution,because energy
requirement is 30.0% lower than in caseof conventional tillage.Second
ranked is system with plough andmultitiller which required 14.0% less
energy in comparison withstandard tillage.Systems which include combination
of chiselplough and powered implements had higher energy requirement
thanconventional tillage,but these were more effective in savinglabour
requirements than conventional tillage.Furtherinvestigations will give us
opportunity to make final conclusionsof each tested tillage system.

Summary: Using unadequate tillage system can cause unnecessary
consumptionof energy ,but every as small as possible saving of energy
issignificant especially if we know that tillage is done on
hugeacreage.Using of proper implements equipped with necessarysupplements
in comparison with unadequate implements can cause upto 30.0% different
energy consumption.For instance one bottomplough without disk coulter
,ploughing soil with high percentageof clay requires significantly more
energy than plough equippedwith coulter.This higher energy requirement can
reach up to31.7%.System of tillage with maximum reduction in
normalconditions requires 138.0 MJ/ha.But other reduced tillage systemswith
lower degree of reduction and usage different seedbadpreparation implements
can cause up to 34.0% differences inenergy requirement.

Summary: For moldboard ploughing, depth of ploughing, plough
construction features, speed of ploughing, soil type and previous crop are
the most important factors that influence energy requirement.This paper
includes investigations that have been carried out from 1987. to
1992.Results of investigation indicate that absence of plough coulter
significantly increase resistance of ploughing.In case of single bottom
moldboard plough, absence of coulter increase resistance for 31.7 % in
comparison with plough that is eqipped with coulter.Every increase of
ploughing speed for 1.0 km/h increase energy requirement for 6.95 %.
Compaction of soil and soil texture directly influence energy
requirement.Texture influence on energy requirement is of linear dependence
type.Compaction of soil with respect to thicknes of packing by Renger, like
texture, influence energy requirement with linear dependence
type.Increasing compaction of soil increase energy requirement.

Summary: Six various tillage systems including five systems of
reduced and conventional system as control were tested in production of
wheat, oilseed rape and maize on silty loam in region western Slavonia. The
aim of investigation was to compare energy and labour requirements of each
system and also influence on yield. Results indicate that tillage system
with single pass of rotary cultivator with integrated drill is one with
lowest energy and labour requirement in wheat production. In oilseed rape
production, single pass of rotary cultivator with integrated drill achieved
the lowest energy and labour requirement, but also achieved the highest
yield. Maize production showed that three systems are more favourable than
others. These are chisel plough+P.T.O. driven rotary harrow, chisel
plough+rotary cultivator and rotary cultivator with integrated drill.
Previously mentioned systems were energy and labour saving systems, but
also achieved good yields.

Summary: Six various systems of tillage were tested in oilseed rape
production in the same working conditions. The aim was to compare energy
and labour requirements for each system. Conventional system was compared
with five systems of reduced tillage. Results indicate that compound
implements consisted of rotary tiller and drill is according to energy
requirement and labour requirement real competitor to conventional tillage,
because mentioned system of tillage has 45.7 % lower energy requirement per
hectare and 51.7 % lower energy requirement per tonne of yield. Four of
five reduced systems are better in energy requirement than conventional
system. In spite of all previously mentioned it must be said that all
reduced tillage systems, except combination chisel plough and rotary
cultivator have 27.0 - 43.0 % lower labour requirement than conventional
tillage system.

Summary: This paper deal with power and energy requirement of
rotarycultivator with two tines arrangement;flat and steep spiral;anstwo
tines shape(L- curved tines and straight
tines.Besidesmentioned,investigation take into account influence of vo/v
ratioand depth of tillage on power and energy requirement.Results showthat
shape of tines and ratio vo/v are more significant factorsof power and
energy requirement than are arrangement of tines anddepth of tillage.On the
contrary shape and arrangement of tinesand depth of tillage show no
influence on final soil conditionwhile ratio of vo/v shows significant
influence on final soilcondition.Straight tines require less power and
energy than Lcurved tines,achieving similar or even better final
soilcondition.
