Abstract
An experiment was conducted at Agricultural Research Farm, NWFP Agricultural University Peshawar during spring 2007. The experiment was laid out in randomized complete block design having four replications. The tillage systems consisted of no-till (NT), conventional tillage (CT) and deep tillage (DT). Maize type sweet corn (Swat local) was sown on April 23, 2007. The net plot size of 30 x 20 m2 was used. The crop was sown as broadcast with seed rate of 60 kg ha-1. Phosphorus and nitrogen were applied at the rate of 90 and 120 kg ha-1, respectively. Weed density and diversity were significantly higher for NT followed by RT and DT. Higher fresh and dry weights of weeds were also noted in NT followed by RT and DT. RT resulted in higher fresh fodder yield followed by DT and NT. Similarly, RT resulted in higher gross income and gross margin. However, comparison showed that NT with less fuel consumption could be a viable economical alternative when the efficiency coefficients are taken into account which was 1:4 for NT.
