Productivity and performance of irrigated wheat farms across canal commands in the Lower Indus Basin AgEcon
Hussain, Intizar; Marikar, Fuard; Jehangir, Waqar Ahmed.
A study of the enormous differences in agricultural productivity that exist across farms and regions in Pakistan, where, for example, recent farm-level data from Sindh, indicates that irrigated wheat output per hectare varies from 0.5 to 5.4 tons across farms. Looks at the central goal of agricultural policy in the country, viz. improving and sustaining productivity, narrowing the existing productivity gaps, and enhancing resource use efficiencies to meet food requirements of a rapidly growing population.

RESOURCE USE AND FARM PRODUCTIVITY UNDER CONJUNCTIVE WATER MANAGEMENT IN PAKISTAN AgEcon
Jehangir, Waqar Ahmed; Ashfaq, Muhammad; Christen, Evan.
The paper describes a study of canal and supplemental ground water used by 544 farmers for wheat crop in the Rechna Doab catchment of Pakistan. The main objective was to assess the on-farm financial gains through conjunctive water use. For econometric analysis, a linear relationship between the wheat production and different determinant variables was assumed. The results highlighted the problem of increased use of tubewells water in the saline zones that had resulted in the deterioration of the groundwater quality and led to the problem of permanent upconing of saline groundwater. Conjunctive water management increased the farm income by about Rs. 1000 and 5000 per hectare compared to only using the canal and tubewell water, respectively The results of...
