ABSTRACT
Contribution of different factors responsible for the increase of Maize production viz: weeds control, insect/pest control and fertilizer were determined in Kharif, 1996 and 1 997 under the agro-climatic conditions of Dera Ismail Khan, Pakistan. The investigations measured the average maximum yield gap between the improved practices and that of farmer`s practices as 2443 kg/ha, showing an increase of 193.88 % over that of farmer`s practices. The highest share contributed by improved fertilizer dose, was 38.48 %; followed by insect/pest control, that was 26 %. The lowest share was contributed by weeds control, 22 %. The highest net return and Value Cost Ratio (VCR) of Rs. 3974.65 and (1:2.2) respectively, were found for fertilizer. The minimum net return of Rs. 1 576.20 with VCR (1:1.47) was obtained for insect/pest control.
