Broad sense heritability and selection response were measured among fifteen rapeseed (Brassica. napus L. genotypes for seed yield and yield related traits during 2010-2011 at The University of Agricultural, Peshawar. The experiment was designed in Randomized Complete Block with three replications. Broad sense heritability estimates were higher (>60%) for primary branches plant-1, pod length, seeds pod-1 and seed yield plant-1. Moderate (30-60%) heritability values were observed for pods raceme-1 and 1000-seed weight. The expected response to selection was higher (≥20%) for seed yield plant-1 whereas, moderate values (10-20%) for selection response were recorded for primary branches plant-1and seeds pod-1. Pods raceme-1, pod length and 1000-seed weight showed lower values (≤10%) for expected response to selection. Higher broad sense heritability estimates and considerable genetic advance could be a valuable tool for breeders to select improved genotypes of Brassica napus for higher seed yield. The genotypes J-35, J-38 and J-40 presented better results for studied traits and hence could be used in future breeding schemes. Source

Vegetables are important source of nutrients for human body. Wastewater irrigation may lead to contamination of these vegetables and cause possible health risk. In the present study impact of waste water irrigation on metals uptake (Fe, Mn, Ni, Co, Zn, Cd, Cr and Pb) by five commonly consumed vegetables (radish, cabbage, lettuce, cauliflower and spinach) grown in the suburbs of Peshawar were investigated using AAS (Atomic Absorption spectrophotometer). The uptake and accumulation of metals for vegetables irrigated with wastewater were significantly (p < 0.05) higher than tube well irrigated vegetables and permissible limits of WHO/FAO. Among the edible parts of vegetables maximum accumulation of Mn, Pb and Cd occurred in radish followed by Ni and Fe in spinach while Cr and Zn were high in cauliflower and cabbage. The estimated daily intake of metals (DIM) revealed that at present the consumption of studied vegetables were under the tolerable limits of (US-EPA, IRIS), however intake of metals in waste water irrigated vegetables were significantly high and can cause health hazards in the long run. © 2015 by Sher Ali Khan.

The present study was conducted to investigate the response of different wheat genotypes to salinity stress. Field experiments were conducted at three different locations of Khyber Pakhtunkhwa Province, Pakistan i.e., Yar Hussain, Baboo Dehari (District Swabi) and Khitab Koroona (District Charsadda) to study the performance of 11 wheat genotypes (Local, SR-24, SR- 25, SR-7, SR-22, SR-4, SR-20, SR-19, SR-2, SR-23 and SR-40) for their salinity tolerance. These locations had different salinity profile i.e., Yar Hussain, EC. 3-3.5 dSm-1; Baboo Dehari, EC. 4- 4.5 dSm-1 and Khitab Koroona, EC. 5-5.30 dSm-1). Different locations and wheat genotypes had a significant (p<0.05) effect on biological and grain yield, shoot Na+ and K+ concentration (3, 6 and 9 weeks after emergence). Maximum biological and grain yield, maximum shoot K+, and minimum Na+ concentration (3, 6 and 9 weeks after emergence) were recorded in genotype SR-40 followed by genotype SR-23. Our results further indicated that maximum biological and grain yield and minimum shoot K+, Na+ concentrations (3, 6 and 9 weeks after emergence) were recorded at Yar Hussain. Maximum, K+ and Na+ concentration (3, 6 and 9 weeks after emergence) and minimum biological and grain yield were observed at Khitab Koroona. Source

A study was initiated to evaluate the effect of different cormel sizes on the growth and development of gladiolus corms in the city of Peshawar, Khyber Pakhtunkhwa, Pakistan. The current study was undertaken at Ornamental Horticulture Nursery, Department of Horticulture, the Agriculture University, Peshawar during 2009. Three different cormel sizes (C1 = >1.5 cm and < 2 cm, C2 = >1.0 cm and < 1.5 cm and C3 = >0.5 cm and < 1 cm of gladiolus cultivar "white Friendship". were planted and the effect of cormel size on growth was assessed. Cultivar white Friendship; has white colour, 30-45cm spikes length, bearing 18-20 florets around 9.5-10.5cm size and at average each corm produces 15-20 cormels (AgrihortiCo: Dissemination of Horticultural information). Number of studies indicated that cormel sizes significantly influence consequent growth and development of corms. In the present study, it was observed that corm and cormel size positively effects on various parameters and the highest values were obtained from large size cormels for sprouting percentage (70.40), number of leaves per plant (6.77), survival percentage (77.46), leaf area (61.14 cm2), plant height (61.25 cm), diameter of corms (3.18 cm), corms weight (9.616 g) and maximum numbers of cormels per plant (4.74). Earliest sprouting was observed in large size cormels (21.5 days), whereas maximum percent increase in cormel size (186.16) was obtained from small size cormels. Source

The present investigation was undertaken to evaluate the effect of priming on spinach with various sources and soaking durations at the Department of Horticulture, Khyber Pukhtunkhwa Agricultural University Peshawar during 2008-09. The experiment was laid down in Randomized Complete Block Design (RCBD) with three replications. Four priming sources (Distilled water, DAP, SSP, SSP+Na2CO3) and soaking durations of 4h interval (4h to 24h) along with control were studied. Number of days to emergence, germination percentage, survival percentage, leaf area (cm2), leaf yield (tons ha-1) and 100 number seeds weight (g) were significantly affected by priming sources and durations. Mean values showed that early emergence (5.952 days), maximum germination percentage (88.14), survival percentage (89.96), plant height (31.24 cm), leaf area (63.12 cm2), leaf yield (14.667 tons ha-1) and 100 seed weight (1.00 g) were observed in plots in which seeds were soaked in SSP+Na2CO3 solution. In case of soaking durations, early emergence (5.917 days), maximum germination percentage (89.42), survival percentage (90.40), plant height (31.16 cm), leaf area (60.72 cm2), leaf yield (14.340 tons ha-1) and 100 seed weight (0.966 g) were recorded in the plots in which seeds were soaked for 24h. Mean values of interactions results showed that early emergence (5.0 days), maximum germination percentage (95.33), survival percentage (95.38), plant height (33.70 cm), leaf area (70.78 cm2), leaf yield (16.257 tons ha-1) were observed in plots where seed were soaked in SSP+Na2CO3 solution for 24h. Overall SSP+Na2CO3 solution proved the best in most of the parameters while distilled water (control) showed comparatively poor performance. Source
