Medicinal plants including A. calamus, P.specie, C. serrata, P.Oweta, M. longifolia T. aficianali, B. implexical, S. specie, and F.volgare were analyzed for proximate composition and mineral content to explain their medicinal properties with their chemical composition. The crude protein content of wild medicinal plant was in the range of 1.7% to 2.7%.The minimum protein was observed in C. serrata followed by B. implexical (1.8%) while the maximum was found in M. longifolia and F. volgare which was 2.7% each. The fiber content of the plants was in the range of 3.2 to 7.3%. The least amount (32%) of fiber was present in M. longifolia and the highest amount of fiber was possessed by P. oweta which contained 7.3% of fiber. The mineral content showed that all the plants were contained lower amount of sodium (Na) and nickel (Ni). However they contained all other mineral in considerable or even in greater amount. Na content of the plants was present in the range of 1.1 to 8.0ug/g. The highest amount was observed in S.specie which contained 8.0 ug/g of the Na. The range of calcium (Ca) content was 234.0 to 408.4. Magnesium (Mg), chromium (Cr), manganese (Mn), iron (Fe), Ni and zinc (Zn) were present in the ranges of 72.5 to 95.0, 2.0 to 14.0, 4.85 to 90.45, 1.20 to 209.25, 18.8 to 81.2, 0.8 to 5.7 and 6.60 to 24.2ug/g respectively. The higher iron and copper contents showed that plants might be helpful in restoring the Fe and Cu deficiency in the body when consumed regularly. The appreciable amount of Zn, Mg and Mn showed that the plant curing effect might be related to their mineral composition. However the presence of Cr and Ni might endanger their used in regular diets, which might cause accumulation of these minerals in the body which are considered as heavy metals when present in large amount.

This study investigated the effects of the ratio of N, P, and K on physiological parameters of leaves during boll development using Bacillus thuringiensis (Bt) cotton cultivars Siza 1 and Sikang 1. As compared with the treatment without P and K application, combined application of N, P and K significantly increased chlorophyll a content by 5.7% and 14.6%, chlorophyll b content by 22.6% and 3.8%, carotenoids content by 14.7% and 9.9%, soluble proteins by 0.6% and 17.5% as well as soluble sugar by 16.8% and 7.9% in the two growing seasons. Similarly, catalase was enhanced by 10.0% and 14.6%, peroxidase by 45.5% and 47.5%, superoxide dismutase contents by 4.9% and 42.2%, and seed cotton yield by 29.2% and 18.7%, respectively. Our study indicated that combined application of N, P, and K at appropriate ratios enhanced the activity of physiological parameters and yield and the ratio of 1:0.6:0.9 considerably performed best for Sikang 1 cultivar amongst all treatments.

Investigations predict that in 21st century the sea level may rise by 1 m or more, which would adversely affect one billion people by 2050. Coastal regions, being major irrigated rice-growing zones, are prone to be devastated by climate change, loss of wetlands, heightened storm damage, and increased salinity from saltwater intrusion. Scientists reported 23% improvement in rice-grain yield due to increasing CO2 from 365 to 627 mg kg−1; however, this increase is nullified by increasing mean air temperature. Both low and high temperature at high and low altitude respectively, reduce rice yield. Scientists found a 10% decrease in rice yield by per degree centigrade increase in minimum temperature. Similarly, decrease in rice yield was noticed in many parts of the world due to scarcity of good quality water, drought, salinity, land degradation, poor weed control, low input use, uneven patterns of rainfall, high disease occurrence, poor soil fertility, and some socioeconomic issues. Therefore, integrated management systems must be developed through eco-friendly agronomic practices, research, and modeling to overcome these hurdles for obtaining sustainable and profitable productivity of rice.

However, farmers use higher or lower fertilizer doses regarding sorghum growth and yield. This study was undertaken to determine the response of sorghum morpho-physiological activities to different rates of nitrogen (N) during two growing seasons of 2017 and 2018. The treatments were consisted of a factorial combination of three N levels (N1 = 0 kg N ha− 1, N2 = 150 Kg N ha− 1, and N3 = 300 kg N ha− 1) and two varieties (V1 = CFSH30, and V2 = Siyong 3180). Treatments were arranged in a randomized complete block design with three replicates. Our results found that N application (N2 and N3) significantly increased plant growth and morpho-physiological activities; leaf length increased by 2.7–8.9%, leaf width by 0.4–4.5%, plant height by 27.8–20.5%, Specific leaf weight by 4.2–10.9%, leaf weight by 18.4–17.4%, and protein contents by 39.5–1...

Consequently, the present study was conducted to explore morpho-physiological traits, photosynthetic pigments, gaseous exchange attributes, antioxidative response and phytoextraction of copper (Cu) in H. cannabinus grown under different levels of Cu i.e. 0 (control), 60, 120 and 180 µmol L−1 in Hoagland nutrient solution (pH 6.2). The results from the present study revealed that Cu toxicity reduced plant height, plant diameter, plant fresh weight, plant dry weight, photosynthetic pigments and gaseous exchange attributes compared to control. Moreover, excess Cu in the nutrient solution ameliorates contents of malondialdehyde (MDA), hydrogen peroxide (H2O2) and electrolyte leakage (EL) which showed that Cu induced oxidative damage in the roots and leaves of H. cannabinus. The oxidative stress which was induced b...

In this incubation study, we explored the ability of PSB (control and inoculated) to release P from different P sources [single super phosphate (SSP), rock phosphate (RP), poultry manure (PM) and farm yard manure (FYM)] with various soil lime contents (4.78, 10, 15 and 20%) in alkaline soil. PSB inoculation progressively enriched Olsen extractable P from all sources compared to the control over the course of 56 days; however, this increase was greater from organic sources (PM and FYM) than from mineral P sources (SSP and RP). Lime addition to the soil decreased bioavailable P, but this effect was largely neutralized by PSB inoculation. PSB were the most viable in soil inoculated with PSB and amended with organic sources, while lime addition decreased PSB survival. Our findings imply that PSB inoculation can counteract the antagonistic effect of soil calcification...

Highlands of Balochistan, Pakistan are also under this threat where underground water has gone down to a drastic level due low rain falls and water mining. To overcome these issues there is a need of alternative approach i.e. Cultivation of high value low delta crops like grapes, olives, pistachio and pomegranate instead of low value high delta crops apple, apricot, cherries and peaches etc. For speeding-up the cultivation of high value low delta crops access to their true to type, disease free nursey plants are very important, which have been addressed in this experiment by developing nursery plants of grapes germplasm, under hydroponics system with semi controlled conditions and supplementation of IBA in the media. The aim of this research was to standardize the protocol for rooting of grapes in hydroponics and to find the optimized concentration of IBA for rooting of grape. Two local germplasm i.e. Haita and Sahibi and two exotic genotypes i.e. Autumn Royal and Red globe of grapes were planted in soil, static hydroponics and continuous hydroponics systems. Shoot cuttings were treated with different concentrations of Indole Butyric Acid (IBA). The grapes genotypes treated with 4000 mg.l-1of IBA had more number of roots and greater root length in both static and continuous hydroponics after one month compared with those which were treated with low concentrations of IBA. Furthermore, cuttings produced their roots in short span of time i.e. one month in hydroponics system compared with those kept in soil.

The experiment was laid down in Randomized Complete Block Design with split plot arrangement having three replications. Four DAP concentrations i.e. 0.5%, 1%, 1.5%, 2% with a difference of 4 hours soaking durations from 4 hours soaking to 48 hours along with un-primed seed were studied. Data were recorded on production traits viz. plant weight (gm), number of pods plant-1 , pod length (cm), number of seeds pod-1 and pod yield (kg ha-1). The results of the study revealed that all the studied traits were significantly affected by concentrations and soaking durations and its interactions. Mean values showed that maximum plant weight (489.12 gm), number of pods plant-1 (35.95), pod length (11.09 cm), number of seeds pod-1 (53.26) pod yield (3845.54 kgha-1) at 0.5 % DAP solution. Mean values of interactions result showed that maximum number of pods plant-1 (47.16) and pod yield (5255.27 kg ha-1) was recorded by the seed soaked for 32hr in 0.5% DAP solution. Maximum number of pod length (12.63 cm) was recorded by the seed soaked for 24hr in 1% DAP solution, whereas, maximum number of seeds pod-1 (66.13) was recorded by the seed soaked for 32hr in 1% DAP solution. DAP solution @ 0.5% performed best in most of the parameters while distilled water showed poor performance. DAP concentrations @ 0.5 % for 32h is recommended for seed priming for obtaining maximum yield in Okra.

The experiment entitled effect of nitrogen and phosphorus on yield and yield components of sesame were conducted at New Developmental Farm of the University of Agriculture Peshawar during kharif (June 2013). Randomized complete block design (RCBD) having four replications were used. Nitrogen and phosphorus levels (0, 30, 60, 90 kg ha-1) each were applied in the form of P2O5 from DAP and urea respectively. The whole of phosphorus was applied during seed bed preparation and nitrogen in two splits, half at sowing and half after 80% emergence. The seed rate 4 kg ha-1 of sesame (ocal black) was planted on 28 th June 2013. Total of 3 irrigations were applied, and other cultural practices were kept uniform for all the treatments. Highest number of pods plant-1 (67), number of seeds pods-1 (54), grain yield (520 kg), biological yield (2539 kg), thousand seeds weight (3.91 g) and harvest index (24%) were recorded when higher dose of N i.e. 90 kg ha-1 were used. Similarly enhanced lowest number of pods plant-1 (55), number of seeds pods-1 (50), grain yield (442 kg), biological yield (1570 kg), thousand seed weight (2.94 g), and harvest index (20%) were recorded in control plots. Application of phosphorous has significantly affected seeds pod-1 , and biological yield. Whereas 90 kg P ha-1 increased plant tallness, pods plant-1 , grains yield, thousand seeds weight and harvest index (%). The interaction was non-significant for all studied parameters. Therefore, it was concluded from the results that using nitrogen @ of 90 kg ha-1 with 90 kg P ha-1 have improved the yield and yield components of sesame. Thus the application of 90 kg N ha-1 with 90 kg P ha-1 is recommended for general cultivation in agro-climatic condition of Peshawar valley.

It has been observed in the past that both diseases have a high correlation that might be due to the abnormal conditions of the liver. But the mechanism of the prevalence of diabetes in patients with chronic HCV infection still remains unclear. In our study, we have investigated T2DM in the male and female patients at Lady Reading Hospital (LRH), Peshawar. The blood samples of both in- and outpatients were analysed in the PCR laboratories of LRH from December 2014 to April 2015. Great prevalence of diabetes in hepatitis C infected male and female patients was observed during this study. The data were collected from the patients through a preplanned questionnaire that included name of the patient, HCV, being diabetic, age, gender, location, educational background, family history of the disease, other diseases, and any treatments if taken. The results...

For this purpose, two fields were selected, one for daytime plowing and other for night time plowing. Night plowing was done at 10.00 p.m. while daytime plowing at 8.00 a.m. Furthermore; half of the plowed field was sown immediately after plowing and the rest, 12 hours later in both plowing treatments. Three hybrids of maize i.e. Monsanto-2021, Rafhan-3313 and Rafhan-3304 were planted in each field under randomized complete block design with four replications. All standard agronomic practices were adopted during the experiment for all treatments. All the observed parameters were significantly affected by plowing time, while sowing time had no impact. Generally, a significant interaction among plowing and sowing time was observed for the recorded parameters. Early emergence (7 days) was observed for the field plowed at night. Plowing the field at usual daytime delayed emergence (9 days). Delayed tasseling (52.9 days), delayed silking (58.6 days), larger leaf area (850 cm 2), delayed maturity (114 days), taller plants (271cm), greater stover yield (12328 kg ha-1) and accelerated crop growth rate (24.98 gm-2 .day-1) were recorded for the field plowed at night. There were also significant differences among various hybrids, where Monsanto-2021 delivered better results. Plowing the field at night proved superior in term of crop growth rate as compared to the field plowed at usual daytime. Night plowing is recommended to increase vegetative performance of maize. Sowing can be done immediately after night plowing or on the subsequent day of plowing. Hybrids particularly, Monsanto-2021 is recommended for better performance.

To study the impact of various placement techniques of different crop residues (i.e. legume residue and wheat straw), fertilizer-N and their various combinations on maize crop; an experiment was conducted at New Developmental Research Farm of University of Agriculture, Peshawar, Khyber Pakthunkhwa. The crop residue/fertilizer was applied at three-placement depths i.e. surface, shallow (3 cm) and deep (6 cm) incorporation for evaluating its utilization efficiency by maize. Randomized complete block design in a split plot arrangement was used in the experiment. Placement depths of the residues/fertilizer showed inconsistent results and did not express significant differences for most of the observations. However, shallow incorporation of the treatments showed good results in terms of ears per plant, total aboveground biomass yield, grains per ear and grain yield. Recommended rate of N-fertilizer and mixture of half fertilizer and full rate of legume residues showed better performance than all other treatments. Maize showed better utilization of N-fertilizer and responded with best results in terms of 1000-grain weight, aboveground biomass and grain yield. Mixture of half fertilizer and legume residue increased performance of maize showing good results for ears per plant and grains per ear. Control (no residue/no fertilizer) showed poor results for almost all traits. While wheat straw amended treatments also had poor effect on the overall growth and development of maize.
