  Contribution of different factors responsible for the increase of sorghum production viz fertilizer, insecticide and weed control were studied in Kharif 1998 and 1999 under agro-climatic conditions of D.I.Khan (NWFP). The investigation measured the average maximum gap between the farmer`s practices and that of improved practices as 2058Kg ha -1, showing an increase of 136 percent over that of farmers practices. The highest share was contributed by fertilizer 45.29 percent followed by insecticide 41.71 % and weed control 12.91 %. The highest net return and value cost ratio (VCR) of Rs.5202 ha -1 and 1:2.26, respectively were found for fertilizer. The minimum net return of Rs.922 ha -1 was obtained for weed control.

  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.

  An experiment was conducted to study the effect of different times of application of herbicides on the yield and yield components of rice under direct wet seeded culture during 1999 and 2000. Results showed that time intervals of herbicide application only affected the dry weed biomass (g m-2) during both the years. While significant differences were observed for number of panicles (m-2) and 1000-grain weight 2 (g) during 1999 and for spikelets per panicle and sterility percentage during 2000 only due to different application times. Results indicated that herbicides application resulted in significant differences of paddy yield and all the yield parameters including straw yield during both the years, except harvest index that was affected by the herbicide application during 1999 only. Curtly it is concluded that herbicides application boosted the paddy yield during both the years.

  Contribution of different factors responsible for the increase of millet production viz: improved variety, fertilizer, seed rate and method of sowing were determined in Kharif, 1996 and 1997 under the agro-climatic conditions of D.l. Khan, Pakistan. The investigations measured the average maximum yield gap between the improved practices and that of the farmer’s practices as 929 kg ha–1, showing an increase of 202.83 percent over that of farmer’s practices. The highest share was contributed by method of sowing, 24.77 percent; followed by improved variety, 24.42 percent, fertilizer, 22.84 percent and seed rate, 7.3 percent. The highest net return and Value Cost Ratio (VCR) of the Rs. 2255.34/ha and (1:5) respectively, were found for improved variety, followed by method of sowing as Rs. 2053.94/ha and 1:3.68 (VCR) respectively. The minimum net return of Rs. 682.84/ha was observed for seed rate.
