| This study uses data from a 2001 survey of Great Plains farmers to explore the adoption, usage patterns, and perceived benefits of computers and the Internet. Adoption results suggest that exposure to the technology through college, outside employment, friends, and family is ultimately more influential than farmer age and farm size. Notably, about half of those who use the Internet for farm-related business report zero economic benefits from it. Whether a farmer perceives that the Internet generates economic benefits depends primarily on how long the farmer has used the Internet for farm business and for what purposes. |

| ABSTRACT: Weeds affect crop growth, health and yield by competing for resources, and they serve as refuge for insect pests. Mulches of different materials have been found to control weeds and insect pests. A field study was conducted at the village of Mang, Haripur, Khyber Pakhtunkhwa, Pakistan, to explore the effect of various mulch materials on weed suppression in maize fields under rain-fed conditions in 2013. Eight mulch materials treatments were used: control (no mulching), wheat straw mulch, dry leaves of eucalyptus, rice straw mulch, grass clippings, living mulch (soybean crop), black plastic mulch and the herbicide Primextra were investigated under a randomized complete block design with four replications. Statistical analysis of data showed... |
