  A field experiment was conducted to study yield and yield components of different cultivars of wheat, barley and oat under rainfed conditions. Statistical analysis of the data revealed that days to emergence, number of leaves tillers-1, number of tillers plant-1, number of spikes plant-1, spikes m-2, grains spike-1, days to heading, thousand grains weight, days to maturity, grain weight and biological yield was significantly affected by different cultivars of wheat, barley and oat. Mean value of the data indicated that those plots which were seeded with full green (oat) produced taller plants and more spikes plant-1. Similarly, fork deer (oat) gave more grains spike-1 and biological yield. Dir local (barley) produced maximum thousand-grains weight. Mean value of the data also indicated that maximum grain yield was produced by avon (oat). When cost benefit ratio was taken into an account Inqualib-91 gave maximum net profit when compared with other crops under study.

  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.

  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.

  For determination of good combiners in Brassica napus L. genotypes, a study was conducted 8x8 diallel during 2004-05 and 2005-06. F1s and parents were evaluated for combining ability for yield associated traits. Analysis of variance revealed highly significant differences (p≤0.01) for all traits. Components of combining ability analysis exhibited that, GCA was highly significant (p≤0.01) for number of seeds/plant, while significant (p≤0.05) for number of pods/plant and pod length whereas non-significant for 1000 seed weight and seed yield/plant. SCA and RCA effects were highly significant for all traits. GCA effects were higher than SCA and RCA for number of pods/plant and number of seeds/pod indicating that additive gene effects controlled the expression of these traits. The SCA effects were of greater magnitude than GCA effects for 1000 seed weight showing the contribution of non-additive gene effects. RCA effects were greater than GCA and SCA for number of pods/plant and seed yield/plant showing that reciprocal crosses have higher potential than direct crosses for these traits. The parent genotypes NUR1, NUR3, NUR4 and NUR9 and hybrids NUR1xNUR7, NUR2xNUR1, NUR2xNUR8, NUR3xNUR1, NUR3xNUR9, NUR4xNUR7, NUR5xNUR2, NUR5xNUR8, NUR7xNUR4 and NUR8xNUR1 had higher GCA and SCA effects, respectively therefore could be exploited for further selection of high yielding progenies. The overall study revealed the importance of both additive and non-additive genetic variability suggesting the use of integrated breeding strategies which can efficiently utilize the additive as well as non-additive genetic variability.
