  To study the effect of sowing dates on the yield and yield components of different wheat varieties an experiment was conducted at Malakandhar Research Farm of NWFP Agriculture University Peshawar during 1999-2000. Statistical analysis of the data revealed that different dates sowing and varieties had a significant effect on emergences m-2, number of productive tillers m-2, number of unproductive tillers m-2, spike length, grain yield and biological yield. While number of unproductive tillers m-2, days to heading and biological yield were significantly affected by interaction between different sowing dates and varieties. Mean value of the data revealed that emergence m-2 (179). spike length (11.33 cm). grain yield (3611.11 kg ha-1) and biological yield (10370.00 kg ha-1) was maximum in those plots which were sown on November 1st when compared with other sowing dates. Similarly variety Tatara-96 recorded maximum emergence m-2, days to heading, number of productive tillers m-2, spike length and grain yield when compared with other varieties under study.

  An experiment to determine the effect of date of transplanting on the agronomic and morphological parameters of rice crop was conducted at Agricultural Research Institute, Dera Ismail Khan during Kharif season of 2003. A total of six transplanting dates; divided into two groups (early and late) were used. Most of the yield and yield contributing parameters (days to 50% heading, leaf folder, stem borer incidence, plant height, tillers hill-1, 1000 grain weight, sterility % and harvest index %) were significantly affected by the two group of dates of rice transplanting. Highest paddy yields (4.53, 4.03 and 4.53 t ha-1) were obtained in early transplanted rice group while seedlings transplanted late were heavily infested by stem borer thereby reducing yield to a larger extent (1.56, 1.94 and 2.24 t ha-1). It has been concluded that early sown rice is a significant contributor towards farmers` livelihood status by giving them increased paddy yields as compared to late transplanted rice.

  A two years study was carried out to see the effect of various herbicides and hand weeding on weed control in wheat. For weed density and grain yield highly significant differences were recorded between treatments and weedy check. The lowest weed density was observed in hand weeding (3.50) which was statistically at par with Puma super + 2,4-D (5.38), Puma super + Buctril M (5.63), Dicuran MA 60 (6.13) and Tolkan (6.75) while the highest weed density was observed in the weedy check (42.38). The maximum grain yield of 2957 Kg ha -1 was obtained in hand weeding and was statistically comparable with the yields of Puma super combined with 2,4-D (2649 Kg ha -1) and Buctril M (2612 Kg ha -1) and Dicuran alone (2556 Kg ha -1). The lowest yield was exhibited by weedy check (1606 Kg ha -1) and was statistically at par with Panther (2003 Kg ha -1).

  Studies on the feasibility of intercropping sunflower (SF) in sugarcane (SC) under different geometrical patterns and fertilizer doses were conducted. Experiment comprised of three fertilizer levels viz., 140:100:100, 160:120:150 and 180:140:200 and seven geometrical pattern viz., sole sugarcane (SC), one row of sugarcane + one row of sunflower (SC 1 row + SF 1 row), SC 2-row strip + SF 1 row, SC 2-row strip + SF 2-rows, SC 3-row strip + SF 2-rows, SC 3-row strip + SF 3-rows, and sole SF. The main effect for fertilizer doses were statistically significant for all the parameters examined. The best performance for all the parameters was shown by the fertilizer application at the rate of 180:140:200 (NPK kg ha-1). The planting geometries differed significantly in affecting the yield parameters of the component crops. The planting geometry of 1SC+1SF gave the second highest net return of Rs.51307 after the sole crop of sugarcane in 1995 and the highest net return of Rs.51084 in 1996 followed by sole crop of sugarcane with net return of Rs.50296. This geometry produced the highest net return and caused the highest reduction in weed biomass thus it helped in avoiding weed control through chemicals, which bring about environmental pollution and hence it is recommended in autumn planted sugarcane for higher income.
