Zero-tillage technology and farm profits : a case study of wheat growers in the rice zone of Punjab

This study presents the results from a field survey of the wheat growers in the rice-wheat zone of Punjab. At present, more than eighty thousand hectares of wheat are sown with zero-tillage drill technology. The results of multiple regression analysis confirmed that the zero-tillage technology enhances water and fertiliser use efficiency. However, sufficient evidence was not present to prove any positive or adverse effect of the technology on the incidence of weeds in wheat crop. It is suggested that this aspect of zero-tillage technology be focused on more in future research. (Pak Development Rev/DÜI)
