  Field experiment was conducted during 1998-99 at Malakandher Research Farms, NWFP Agricultural University, Peshawar, Pakistan to study the effect of seed rate on the yield and yield components of wheat cultivars under irrigated conditions of Peshawar. Statistical analysis of the data revealed that the plots treated with 150 kg ha-1 seed rate had higher emergence m-2 (56.00 plants m-2), number of tillers m-2 (264.37), number of productive tillers m-2 (252.62 tillers m-2), plant height (98.25 cm) and grain yield (2345.90 kg ha-1). Days to maturity were maximum in those plots, which were seeded with 100 kg ha-1. Number of grains spike-1 and thousand grain weight were more in those plots seeded with 50 kg ha-1. Mean value of the data also indicated that in case of cultivars emergence m-2 (48.88 plants m-2), plant height (96.75 cm) and thousand grains weight (43.50 g) was maximum in plots seeded with Inqilab-91. Number of tillers m-2 (272.25), number of productive tillers m-2 (263.75) days to maturity (153.50 days), number of grains spike-1 (44.00) and grain yield (2530.37 kg ha-1) was higher in plots sown with Bakhtawar-92.

  The research work was conducted to study the effect of nitrogen (0, 40, 80 and 120kg ha-1) and sulphur (0, 30, 60 and 90kg ha-1) on the yield and oil contents of canola variety Dunkled. Data were recorded on number of branch plant-1, pods plant-1, seeds pod-1, 1000 grain weight, grain yield (kg ha-1) and oil content. The effect of nitrogen was significant on all the parameters. Plots that received highest dose of N (120 kg ha-1) had maximum number of branches plant-1 (14), pods plant-1 (760), seeds pod-1 (28.04), thousand grain weight (3.15 g) and grain yield (2653 kg ha-1), while minimum oil content (42.1%). Different doses of sulphur had significantly increased number of branches plant-1 (12), pods plant-1 (582), grain yield (1683 kg ha-1) and oil content (44%), but had not significantly affected seeds pod-1 and 1000 grain weight. Grain yield was significantly higher at the highest levels of both the nutrients applied.

  The research was conducted to study the effect of nitrogen (0, 40, 80 and 120kg ha-1) and sulphur (0, 30, 60 and 90kg ha-1) on the yield and oil contents of canola (Dunkled vareity). The effect of nitrogen was significant on grain yield, oil content erucic acid, but had not significantly affected glucosinolate content. Plots that received highest dose of N (120kg ha-1) had maximum grain yield (2653kg ha-1) but minimum oil content (42.10%) and erucic acid (0.31%). Different doses of sulphur had significantly increased grain yield (1683kg ha-1), oil content (44%) and erucic acid (0.50%) but had not significantly affected glucosinolate content. Grain yield was significantly higher at the highest levels of both the nutrients applied while oil contents decreased with increase in level of sulphur to 90kg ha-1 (43.19%) and nitrogen to level of 120kg ha-1 (42%). The result indicated that glucosinolate is not effected by the two nutrients i.e., N and S.

  All the parameters i.e., days to emergence, days to flowering, days to physiological maturity, number of pods per plant, number of seeds per pod, 100-seeds weight, biological yield, grain yield were significantly affected by sowing dates. Less days to emergence (6.6), less days to flowering (40) and less days to physiological maturity (75.7) were recorded. Biological yield was maximum for June 15 (6000 kg ha-1) followed by July 01(5439 kg ha-1). Number of pods per plant, number of seeds per pod, 100-seeds weight (g), grain yield (kg ha-1) got highest value of 30.2, 5.1, 4.26 and 825 respectively for July 01 sowing. Effect of the various mashbean varieties was significantly different for number of pods per plant, number of seeds per pod, biological yield and grain yield. Among these parameters highest number of pods per plant (20.6) for NARC Mash-1, higher number of seeds per pod (4.9) for NARC Mash-3, greatest biological yield (4400 kg ha-1) for NARC Mash-4 and more grain yield (557.1 kg ha-1) for NARC Mash-1. Interaction between varieties and sowing dates did not significantly affect any parameter. It may be concluded that July 01 sowing date and NARC Mash-1 variety appeared to be suitable for irrigated condition of Peshawar valley.

  Field experiment was conducted at Agricultural Research Station Serai Naurang, Bannu to find out the effect of two weedicides, i.e., Ronstar @ of 3 kg ha-1 and stomp 330E @ 4 lit ha-1 along with hand weedings, i.e., 2 and 4 times, keeping the required intervals in onion crop. Onion cultivar transplanted was Swat-1. The data were recorded on fresh yield with leaves; dry yield with leaves and bulb yield without leaves tons ha-1. From the analysis of data, using LSD test, it was observed that fresh yield, dry yield and bulb yield tons ha-1 of onion were significantly increased with the application of Ronstar @ of 3kg ha-1 which produced 30.51, 26.33 and 25.19 tons ha-1, respectively. Four times hand weeded plots followed the Ronstar treated plots and produced fresh yield, dry yield and bulb yield of 27.66, 23.71 and 22.10 tons ha-1, respectively.

  The wheat crop is more important than other crops, where the year 1998 was declared as wheat year (Economic Survey, 1997-98). In this paper an efforts has been made to highlight necessary variables for increasing the production (grain yield) of wheat. The best subset model was identified with “all possible regression” approach based on selection criteria R2-adjusted. For analysis, data was taken from the experiment conducted at Malakandher farm NWFP Agricultural University Peshawar during the Rabi season 2000-01, to assess the contribution of different agronomic variables on grain yield of wheat (Ghaznavi-98). The best subset model selected was the model having spikelets spike‾1 as predictor because it contributes 82.2% of the variation in the grain yield. The plant heights showed zero% variation in the grain yield.
