Concerted efforts are being made at micro as well as macro
levels in Pakistan to increase farm production and raise productivity in
the agricultural sector. For diagnostic purposes and for formulation of
general guidelines for an intelligent decision making, at micro and
macro levels, it is important to identify and quantify the contribution
of various factor inputs, especially of those factors whose supplies can
be more easily changed in the short run. Satisfactory quantitative
estimates of resource productivity in the pro¬duction of major crops in
Pakistan are generally not available. Except for a few studies carried
out on wheat [2], not much is known about the contribution of various
factor inputs, such as farm labour, fertilizers, etc., to the final
output. The main objective of this paper is to estimate and analyse the
resource pro¬ductivity of various factor inputs obtaining in the
Punjab's agriculture. The estimates are derived from production function
analysis performed on the major crops of the province, i.e. Mexi-Pak and
local wheat, Basmati rice, IRRI rice, Jhonna rice, maize (corn), cotton
and sugarcane. The marginal product¬ivities of various farm inputs in
the production of various crops are computed from the estimated
production functions.
