  The present study was designed to evaluate different honey samples obtained from local market for their quality parameters for assessment of their feasibility for foreign export by comparing it with international standards. The study was conducted at PCSIR laboratories complex, Peshawar, during 2006. The tested samples were evaluated for moisture content, Ash percentage, acid content, HMF and reducing sugars percentage. The moisture content of locally produced honey was in the range of 14.5 to 18.23%. The ash content of locally produced honey samples ranged between 0.047-0.35 which is within the standard limits. The acid content of the honey samples ranged between 19.5 and 38.0 meq kg-1. The HMF contents of locally produced honeys ranged from 5.3 to 23.20 mg kg-1. The content of reducing sugar of the tested samples ranged between 43.14 and 81.40% for the tested samples of locally produced honey. All of the samples were found to be in acceptable range of international standards for all of the tested parameters except for only one sample with lower reducing sugars. These samples were marked to be according to the international standards and are healthy for human consumption.

  The physio-morphic influence of 10 different insecticides from 4 major groups of modern synthetic insecticides, compounds with new pesticidal chemistry, surfactants and emulsifiers in form of five different latest recommended schedules were studied on newly released cotton cuitivar FH-672 at Faisalabad (Pakistan). The experiment was laid out in randomized complete block design (RCBD) with four repeats. The physio-morphic characters under present research investigations were plant height, weight of dry leaves, weight of dry branches, weight of dry stem, number of leaves, number of branches, number of unopened bolls, number of opened bolls, leaf area index, leaf area and seed cotton yield. Results revealed that spray-schedules influenced only 4 physio-morphic characters like seed cotton yield, plant height, leaf area index and leaf area. The final performance was negatively correlated with leaf area index and leaf area. All other characters did not show any correlation to seed cotton yield.

  A preliminary infection experiment was carried out during 2005-06 to identify slow yellow rusting sources of resistance in 20 NIA-wheat breeding lines along with Morocco as susceptible check at Nuclear Institute for Food and Agriculture, Peshawar. It was revealed that the current pathotypes of Puccinia striiformis West. tritici (Pst) were found virulent on all tested genotypes except NIA-6 and NIA-14. Host-pathogen compatibility in remaining lines facilitated the assessment of slow rusting trait and it was assessed through the epidemiological parameters viz., Final Rust Severity (FRS), Area Under Rust Progress Curve (AURPC) and Infection Rate (IR). Maximum FRS of 70% was rated in five lines while in the remaining 13 lines it ranged between 10 to 60%. Relative AURPC values up to 30% of the susceptible check were recorded for 10 lines while up to 70% for eight lines, showing desirable and good slow rusting behavior, respectively. Relative infection rate values ranged from 0 for NIA-7 to 1100-1300, recorded for eight lines. NIA-7 has a constant severity of 10% over assessment dates with lower AURPC value and was considered as better slow rusting line. Among various epidemiological parameters used for assessment of slow rusting trait, AURC was found to be a reliable parameter. Infection rate, on the other hand did not reveal the actual slow rusting behavior of the tested lines. Based on slow rusting trait, the tested lines may probably have genes for varying degrees of slow yellow rusting and can be used for further manipulation in wheat improvement program after confirmatory studies.

  The study to evaluate the effect of nitrogen levels and herbicide doses on wheat growth and yield was carried out. The data revealed that the herbicide, Topik @ 300 g ha-1 gave an effective weed control which reduced weed-crop competition, exhibited positive effect on development of productive tillers, ear length and grain number per ear. All these attributes contributed to higher yield. Application of nitrogen @ 125 kg ha-1 also resulted in higher grain yield over 100 kg N ha-1 application rate.

  Naturally infected grains of nineteen candidate wheat lines along with local check were studied for black point symptoms at Nuclear Institute for Food and Agriculture (NIFA), Peshawar, during 2005-06. Data were recorded on the percent incidence, black point symptoms and thousand grain weights. Results indicated that all tested candidate varieties were found susceptible to A. alternata but they differed in symptoms, incidence and severity of infection. Variability in number of affected kernels among candidate varieties fluctuated between 1.2-20.1% while its mean was < 10%. Low level incidence (i.e., < 3%) was recorded in three candidate varieties i.e., 99B4012, NRDW-1 and Wafaq 2001. Percentage of the kernels with >50% disease coverage (i.e. infection severity) varied among the tested cultivars and it was highest (i.e., 30%) in V-99022. Symptoms which were observed in all cultivars included black point, dark smudge and black specks. Based on the disease incidence level of each candidate variety, an inference regarding disease situation under field conditions was derived in which up to 46 infected seeds capable of producing disease will be entering per m2 of the field. Field prediction along with incidence and symptoms severity may be utilized as selection criteria for commercial and upcoming breeding lines and cultivars.

  Wheat yield of 37 wheat varieties along with a susceptible check, Morocco, was studied under yellow rust pressure across 3 locations of North West Frontier Province (NWFP), Pakistan during 2007. Considerable high disease pressure, as revealed by yellow rust severity, was observed at all locations with the maximum (100%) at Cereal Crop Research Institute (CCRI), Nowshera. Disease severity ranged from 0% to 70% for the tested varieties while reached 100% for Morocco with S type of host response. We report the presence of sufficient variability across locations for both yield potential and yellow rust severity. Locations with maximum disease pressure had lower mean grain yield and vice versa. NIFA followed by AUP had higher mean grain yield (5533 kg ha-1 and 4292 kg ha-1, respectively) with lower maximum disease severity values (70% and 80%, respectively). CCRI had higher disease pressure (100% severity for Morocco) with lower mean grain yield (3676 kg ha-1). Bahawalpur-95, Suleman-96, Kohsar-93, Fakhre-Sarhad, Tatara, and Frontana had relatively stable severity across locations in a range of 0% to 10%. Based on overall traits, Kohsar-93, Bakhtawar-92, Saleem-2000, Fakhre-Sarhad, Tatara, and Karwan had better yield and lower yellow rust severity and is recommended for cultivation and further breeding exploitation.
