Abstract
This study attempts to provide a better understanding of
factors affecting rice farm productivities in the Krian rice growing
area. It also supplies additional material for the regional study of
one of the oldest irrigation schemes in Malaysia.
The application of multiple regression analysis to sample
cross-section input-output data resulted in the explanation of a
statistically significant percentage of variation in gross padi production.
Conventional analysis merely makes statements of management
effects. The differences between average and frontier production
function underscores differences in managerial ability of farmers
operating on the frontier compared to those operating on the outer
bound. This analysis takes cognizance of management effects by way of
management entered as explicit variables. The theoretical consideration
therefore means that average and frontier functions are the same;
any differences that exist are due to differences in management ability
and random disturbances. The inclusion of management ability
marginally improved the fit of the Cobb-Douglas function. Significant
and substantial resource productivity differences were found between
management groups. As such, extension induced technical change to
increase farm output is likely to widen this gap and accelerate the
degree of relative performance, given the existing technique of the
extension programme. Extension strategies and programmes therefore
must take cognizance of this fact. The reluctant adopters of modern
technology must not be neglected in favour of the much more advanced
adopters. The recognition should also be given to land, soil and
irrigation quality which contribute the major share of the explanation
in variation. The strategy therefore is to identify areas where productivity
can be increased. Fertiliser and management ability factors
seems the obvious choice. Research needs to be conducted to further
improve fertiliser productivity. Extension strategies developed should
likewise aim at improving the management ability of all farmers, with
special attention given to the less modem farmers. Religious, social
and other economic factors must also be analysed to provide a general
framework of understanding of factors apart from those already discussed.
