  In order to study the effect of foliar versus broadcast application of various nitrogen levels on the yield and yield components of barley, an experiment was conducted at Malakandher Research Farms, NWFP Agricultural University, Peshawar during 1999-2000. Statistical analysis of the data revealed that various doses of nitrogen and their methods of application had a significant effect on plant height, days to heading, days to maturity, number of grains spike-1, productive tillers m-2, spike length, thousand grains weight, grain and biological yield. Plant height and days to heading was maximum when nitrogen was applied at the rate of 140 Kg ha-2. When the effect of application method was taken into account, it was observed that foliar application of nitrogen had a profound effect on plant height, days to heading, days to maturity, number of productive tillers m-1, number of grains spike-1, thousand grains weight, grains yield, biological yield and harvest index. Foliar application of nitrogen resulted in taller plants, heavier grain and maximum grain yield and biological yield.

  In order to study the effect of different irrigations levels on chickpea, an experiment was conducted at Malakandher Research Farms, NWFP Agricultural University, Peshawar during 2000.Statistical analysis of the data showed that irrigations levels had a significant effect on emergence unit area -1, days to flowering, days to maturity, pods plant -1, grain yield and biological yield. Maximum emergence unit area -1, pods plant -1, plant height, grain yield, biological yield and harvest index in most of the cases were recorded in those plots, which were given two irrigations, when compared with other treatments. In case of varieties, maximum emergence unit area -1, pods plant -1, grain yield, biological yield and harvest index were recorded in NIFA-95 while CM-72 gave minimum emergence unit area -1, grain yield, biological yield and harvest index. The highest biological yield was obtained from plots treated three times, while the lowest biological yield was obtained from control plots. Maximum grain yield was produced by plots irrigated two times, while minimum grain yield was produced by control plots. Maximum harvest index was obtained from control plots and seeded with CM-72, while minimum harvest index was recorded in plots sown with CM-72 and applied three irrigations.

  The study was conducted to determine the frequency of various N levels, lodging and seed quality in wheat, at Malakandher Research Farms, NWFP Agricultural University, Peshawar, during 2000. Statistical analysis of the data revealed that various levels of nitrogen had a significant effect on all parameters except seed vigor. Plots fertilized with 170 kg N ha-1 had maximum productive tillers m-2, spikelet spike-1, grains spike-1, grain yield and harvest index. Whereas minimum biological yield was recorded in plots fertilized with 200 kg N ha-1. Nitrogen levels of 140 kg ha-1 significantly increased germination %age and seed size by weight. In case of nitrogen application frequencies, plots applied with nitrogen in 2 split doses i.e., 50 % at seeding time and 50 % at 2nd irrigation significantly increased number of productive tillers m-2, spikelets spike-1, grains spike-1, grain yield, harvest index, germination % age and seed size by weight. However, nitrogen applied in full at 2nd irrigation recorded maximum biological yield.

  This experiment was conducted to study the beneficial effect of legumes and inorganic quantities of N on maize crop. Different levels of nitrogen i.e. 0, 40, 80 and 120 kg ha-1 were used. Besides maize alone, intercrops were; maize+mungbean, maize+pigeon pea and maize+janter. Maize @ 40, mungbean 20, pigeon pea 50 and janter at 25 kg ha-1 were used respectively. Maximum seedlings emerged m‾2 (40.20) was obtained at 120 kg N ha-1 in maize alone. Maximum days (61.7) to earing were taken by maize intercropped with janter. Maximum days (67.50) to silking were taken by maize+janter intercrop at 0 kg N ha-1. Maximum plant height (165.50 cm) was observed in maize alone at 120 kg N ha-1. Maximum cob length (12.55 cm) was noticed in maize and mungbean intercrop under 40 kg N ha-1. Maximum biological yield (28429.63 kg ha ha-1) was obtained from maize alone by 40 kg N ha-1. Maximum number of grains cob-1 (309) was obtained from maize and pigeon pea intercropping at 120 kg N ha-1. For maximum yield potential maize alone and maize+mungbean intercropping was at par statistically at 80 and 40 kg N ha-1 by giving 3463 and 3444 kg ha-1 yield, respectively. Overall legume intercrop was superior by decreasing less yield of maize crop in addition to legume seed yield and N cost minimization.

  An experiment was designed to investigate the feasibility of using extract of sorghum as a natural weed control approach in comparison with hand weeding and herbicides for wheat crop. The experiment was conducted at Agricultural University Research Farm of NWFP Agricultural University, Peshawar during 1999-2000. Ten treatments were studied in the experiment including check, hand wedding, herbicides Assert and Diazon and 20, 30 and 40 kg sorghum extract ha-1 applied once and twice. Mature sorghum herbage was used for preparing water extract in 1: 20 ratio i.e. 1 kg sorghum herbage soaked in 20 L of water. Sorghum extracts of 20, 30 and 40 kg ha-1 were applied twice, 55 days after sowing and 85 days after sowing. Hand weeding was carried out as required while no weed control was done in check plots. All the weeding control treatments significantly affected seed filling duration, weeds weight, weeds number and grain yield. Sorghum extract also reduced weeds number and weeds weight. Plots sprayed with Diazon herbicides application resulted maximum mean tiller growth rate (0.05 g day-1). Diazon reduced weds mass and weeds number. Sorghum extract at the rate of 30 kg ha-1 twice increased fresh (13.25 g) and dry (6.28 g) and grain yield (4318 kg ha-1) as compared to check plots.
