Estimating Productivity Gap and Contribution of Wheat Production in Sindh Pakistan

Abstract

Shaheed Benazirabad farmers were divided into groups named high yield group, medium yield group and low yield group. The farmers applied an average of 45.27 kg, 45.82 kg and45.18 kg seed per acre respectively. Though, there is not a very large difference in average seed used by both farmer groups but the later used less quantity of wheat seed per acre to some extent. The impact of different factors on these groups was measured through multiple liner regression models. It was found that there exists a yield gap of 17.84 mounds per acre between high yield group and research station. The yield gap between medium and high group was 8.02 Mds per acre while the yield gap between medium group and low yield group was 5.93 Mds per acre. The standard error of estimates F-statics and R-square for high yield group was 0.0623, 2.470 and 0.398 respectively, for medium yield group 0.0314, 3.231 and 0.486 respectively and for low yield group 0.056, 1.342 and 0.345 respectively. The other objective of the study was to calculate the growth rate of wheat in District Shaheed Benazirabad Sindh. The exponential function was used to calculate the growth rate. It was found during study that the growth rate of wheat in Pakistan was 2.59%, 2.94% growth of wheat in Sindh and in District Shaheed Benazirabad was -1.17%, 9.75% respectively.
