Effect of Increasing Levels of Phosphorus and Seed Rate on the Economic Yield of Maize
M. Qasim,Himayatullah,M. Subhan
Journal of Biological Sciences , 2001,
Abstract: Number of cobs per plot, 1000-grain weight and grain yield were significantly effected by various levels of phosphorus and seed rate. Maximum number of cobs per plot (72.58), 1000-grain weight (334.08 g) and grain yield (3154.43 g) were obtained from plots receiving P2O5 @ 200 kg ha -1. Similarly, seed rate @ 60 kg ha -1 gave comparatively higher economic yield. Hence P2O5 @ 200 kg ha -1 and seed rate @ 60 kg ha -1 proved to be the best fertilizer and seed rate among all the treatments.

Mohammad Subhan,M. Qasim,Khalil Ahmad
Asian Journal of Plant Sciences , 2002,
Abstract: An 8 x 8 diallel analysis study on cotton (Gossypium hirsutum L.) was conducted at Faculty of Agriculture, Gomal University, D. I. Khan, during, 1996-99 to determine the type of gene action in the control and expression of some important quantitative characters like seed index and lint index in F1 and as well as in F2 generations. The analysis of variance exposed that differences among genotypes for the characters mentioned were highly significant. The Hayman-Jinks model proved to be partial adequate for the characters mentioned in F1 while completely adequate in the F2 generations in this manuscript.
Synthesis, characterization of a multi-component metal oxide (Al0.88Fe0.67Zn0.28O3) and elimination of As (III) from aqueous solution.  [PDF]
M. A. Subhan, S. A. Monim, M. B. R. Bhuiyan, A. N. Chowdhury, M. Islam, M. A. Hoque
Open Journal of Inorganic Chemistry (OJIC) , 2011, DOI: 10.4236/ojic.2011.12002
Abstract: The multi-component oxide (Al0.88Fe0.67Zn0.28O3)) surface (abbreviated as MCOS) was prepared to optimize the effectiveness of the elimination of As (III) from aqueous solution. The oxide surface was synthe-sized by co-precipitation method using corresponding metal carbonates. It was characterized by XRD, TGA and DSC. The surface morphology of MCOS was observed in SEM and the elemental analysis was accomplished by EDX. The composition of Al2O3, Fe2O3 & ZnO was 23.6, 39.9 and 20.6 wt% respectively in XRF analysis. The specific surface area was found 389.85 m2 g-1. Batch experiments were performed to remove As (III) from aqueous solution considering various parameters such as effect of pH, contact time, initial arsenic concentration, temperature and sor-bent dosage. The maximum sorption capacity of the surface was almost steady from pH 4 to pH 9. Kinetic study shows that As (III) sorption is following second order rate equation with the rate constant of 80×10-2 g mg-1 min-1 at room temperature and this rate was increased with increasing temperature which indicates the sorption was endothermic process. The free energy change, ΔGo was negative which proves that the sorption was spontaneous and thermodynamically favorable. Sorption isotherm was interpreted by Langmuir equation and the maximum sorption capacity of oxide monolayer was 13×10-2 mg g-1.
Response of Rice to Different Methods of Zinc Application in Calcareous Soil
M. Umar Khan,M. Qasim,M. Subhan,M. Jamil
Journal of Applied Sciences , 2003,
Abstract: In a field experiment, comparative effect of three different methods of zinc application was studied, aimed at alleviating Zn deficiency in transplanted flood rice (cv.IRRI.6) grown in alkaline calcareous soil. Three methods were tried i.e. nursery root dipping in 1.0% ZnSO4, 0.20% ZnSO4 solution spray after transplanting and 10 kg Zn ha-1 by field broad cast method. Zinc content of soil before flowering and after harvest was increased significantly for all the methods. The yield and yield parameters increased significantly by the application of Zn by any method. Among the methods the effect of Zn was non-significant on yield components like tillers m-2, spikelets panicle-1, % filled grains, 1000-grain weight and straw yield. However, soil application of Zn @ 10 kg ha-1 was rated superior because it produced significantly higher paddy yield.
Genetic Basis of Variation in Upland Cotton (Gossypium hirsutum L.)
Mohammad Subhan,M. Qasim,M. Ameen Khan,M. Amir Khan
Asian Journal of Plant Sciences , 2002,
Abstract: An 8x8 diallel analysis study on cotton (Gossypium hirsutum L.) was launched at Faculty of Agriculture, Gomal University, D.I.Khan, during, 1996-99 to resolve the type of gene action in the inheritance and expression of some significant quantitative characters like number of seeds boll -1 and staple length in F1 and F2 populations. The analysis of variance revealed that differences among genotypes for these traits were highly significant. The Hayman-Jinks model proved to be completely adequate in case of staple length in both the populations. Even though it is adequate for number of seeds boll -1 in F1 but partially adequate in F2 population.
Effect of Zinc Application by Different Methods on the Chemical Composition and Grain Quality of Rice
M. Umar Khan,M. Qasim,M. Subhan,Riazud Din Ahmad
Journal of Applied Sciences , 2003,
Abstract: A field experiment was conducted to evaluate the comparative effect of Zn levels applied by different methods i.e. nursery root dipping in 1.0% ZnSO4, 0.20% ZnSO4 solution spray after transplanting and 10 kg Zn ha-1 by field broad cast method. A significant increase in Zn content of rice leaf before and after flowering and a significant decrease in P content of straw and paddy and starch content of paddy was recorded for all the methods. N, K and Zn of paddy and straw and Zn contents of roots increased significantly with the application of zinc irrespective of the methods over control. Soil application of Zn was rated superior because it gave significantly higher content of N in rice paddy.
Antagonism of Antinociceptive Effect of Hydro-Ethanolic Extract of Hypericum perforatum Linn. By a non Selective Opioid Receptor Antagonist, Naloxone
F. Subhan,M. Khan,M. Ibrar,Nazar-ul- Islam
Pakistan Journal of Biological Sciences , 2007,
Abstract: Hydro-ethanolic crude extract of Hypericum perforatum Linn. family hypericaceae (St. John`s Wort) aerial parts (Hp. Cr) was studied for its possible antinociceptive effect against acetic acid-induced abdominal constriction assay in mice. Hp. Cr (10-20 mg kg-1), opium (10-30 mg kg-1), morphine (0.75-3.0 mg kg-1) and aspirin (50-100 mg kg-1) showed dose-dependent antinociceptive effect. In animals treated with naloxone (0.5 mg kg-1), the antinociceptive effect of Hp. Cr was significantly reduced similar to that of opium, while effect of aspirin remained unchanged. These results suggest that the antinociceptive effect of Hypericum perforatum may be mediated through activation of opioid receptors.
Assessment of Genetic Mechanism in Some Important Quantitative Parameters in Upland Cotton (Gossypium hirsutum L.)
Mohammad Subhan,M. Qasim,Hameedullah Niazi,M. Ameen Khan
Asian Journal of Plant Sciences , 2002,
Abstract: Diallel cross analysis of eight parents of cotton (Gossypium hirsutum L.) was launched at Faculty of Agriculture, Gomal University, D.I.Khan, during 1996-99. Both additive and non additive effects were observed in case of number of bolls plant -1 in F1 generation, however only additive effects were significant in F2 generation. Significant additive and non additive effects were observed for boll weight in both the generations. The reciprocal differences were non significant for number of bolls plant -1 in both the generations, reflecting the absence of maternal effects or any other departure from simple autosomal inheritance. On the other hand significant reciprocal differences were concluded for boll weight, signifying the presence of maternal effects in F1 but non significant, suggesting the absence of maternal effects in F2 generation.

Hidayatullah Khan,M. Subhan,Sultan Mehmood,M. Faran Durrani
Biotechnology , 2008,
Abstract: Low molecular weight serine protease has been purified from the seeds of Holarrhena antidysenterica to electrophoresis homogeneity by the combination of size exclusion and ion exchange chromatography. The molecular mass was estimated by SDS-PAGE to be about 25 kDa. The enzyme showed optimum activity at pH 7.5 and exhibited its highest activity at 35°C using 1% casein as a substrate. The enzyme was strongly inhibited by 2 mM PMSF but not by EDTA and cysteine protease inhibitors, suggesting the presence of serine residues at the active site. The enzyme had a Km of 1.1 mg mL-1 and Vmax of 389.71 units min-1 mg-1 of protein.
