A field study was conducted to evaluate the effect of organic m.lches and tillage practices on growth, yield of cluster bean and soil physical properties. Experim.nt was com.rised of two factors: A (Tillage), B (m.lches). Factor A was assigned to m.in plot and consisted of two treatm.nts (m.nim.m.tillage and Conventional tillage). Factor B was assigned to sub plot and consisted of four treatm.nts (no m.lch, wheat straw m.lch, grass clipping m.lch and saw dust m.lch). The m.lching m.terials were partially incorporated in the field after germ.nation of crop. The experim.nt was laid out in Random.zed Com.lete Block Design (RCBD) with split plot arrangem.nt having three replications. Control treatm.nt was kept for com.arison. All other agronom.c practices were kept standardized and consistent for all the treatm.nts. Data regarding growth and yield com.onents were collected and analyzed statistically by fisher analysis of variance and treatm.nt significance was m.asured by significant difference test at 5% probability level. The factors, tillage and m.lches significantly affected growth, yield, yield param.ters and soil physical properties. m.xim.m.plant population (31.7 m.sup>2), plant height (159 cm., branches per plant (18.9), cluster per plant (15.88), grains per pod (7.3), 1000-grain weight (34.6 g), grain yield (1.9 t•ha-1), biological yield (9.91 t•ha-1) and harvest index (19.15) was recorded in conventional tillage com.arative to m.nim.m.tillage. m.lches also affected grain yield, and m.xim.m.grain yield was recorded in wheat straw m.lch (1.88 t•ha-1) followed by grass clipping m.lch (1.81 t•ha-1) and saw dust m.lch (1.76 t•ha-1) while m.nim.m.grain yield was recorded in control without m.lch application (1.67 t•ha-1).

Yield and Quality of Forage Oat (<i>Avena sativa</i>L.) Cultivars as Affected by Seed Inoculation with Nitrogenous Strains

引用

Am.rican Journal of Plant Sciences 2015年第19期6卷 3251-3259页

作者： m.ham.ad Saleem.m. Shahid Ibni Zam.r Ihtisham.l Haq m. Zahid Irshad m. kamran khan m. Asim.Qam.ruz Zam.n Ihtisham.Ali Am.n khan Saeedur Rehm.n Departm.nt of Agronom. University of Agriculture Faisalabad Pakistan

Nitrogen availability can be enhanced with the application of nitrogen fixing bacteria and it m.y be helpful in increasing forage yield and im.roving quality of oat. Therefore, a field trial to evaluate the effect of seed inoculation with nitrogen fixing bacteria on forage yield and quality of oat was carried out at Agronom.c Research Area, University of Agriculture, Faisalabad during Rabi season 2013-14. The experim.nt was laid out in Random.zed Com.lete Block Design (RCBD) with factorial arrangem.nts using three replications. The experim.nt was com.rised of two integrated approaches. The first approach was oat cultivars consisting of four treatm.nts, V1 (AVON), V2 (S-2000), V3 (S-2011) and V4 (PD2LV65) and the second approach was seed inoculation consisting of three treatm.nts, S0 (control), S1 (Azotobacter spp.), S2 (Azospirillum.spp.). Fisher’s analysis of variance technique was used for statistically interpretation of data by using least significant difference (LSD) test at 5% level of probability. Nitrogen fixing bacteria significantly affect the germ.nation count (m.), plant height (cm., num.er of tillers (m.), num.er of leaves per tiller, leaf area per tiller (cm.), green forage yield (t·ha-1) and dry m.tter yield (t ha-1). The m.xim.m.green forage yield (85.2 t·ha-1), dry m.tter yield (14.1 t ·ha-1) and crude protein (11.5%) were recorded where Azotobacter inoculation was applied. The interaction between cultivars and nitrogenous strains was significant for green forage yield (t·ha-1), dry m.tter yield (t·ha-1) and crude protein (%). Conclusion showed that cultivar Sargodha-2011 which was inoculated with Azotobacter spp. gave higher forage yield of good quality.

Am.rican Journal of Plant Sciences 2016年第6期7卷 789-797页

作者： m.ham.ad Naeem.Shahid m. Shahid Ibni Zam.r Ihtisham.Ul Haq m. kamran khan m.zhar Hussain Usm.n Afzal m. Asim.Ihtisham.Ali Departm.nt of Agronom. University of Agriculture Faisalabad Pakistan

A field study to evaluate the im.act of different tillage regim.s and nitrogen levels on yield and yield com.onents of m.ize (Zea m.ys L.), was conducted during autum. 2014 at Students Farm. Departm.nt of Agronom., University of Agriculture, Faisalabad. The experim.nt was laid out in RCBD (Random.zed Com.lete Block Design), with split plot arrangem.nt having three replications. The experim.nt was com.rised of three tillage regim.s (m.nim.m. Conventional and Deep) and three nitrogen levels viz: 100, 200 and 300 kg•ha-1. Urea was used as a source of nitrogen, sulphate of potash as a source of potassium.and triple super phosphate as a source of phosphorous. The am.unt of phosphorous and potash was constant in all the treatm.nts i.e. 125 kg•ha-1 and 100 kg•ha-1 respectively. Results of present study are sum.arized as yield param.ters are significantly affected by different nitrogen levels and tillage regim.s. m.xim.m.num.er of plants at harvest (7.93), num.er of grain rows per cob (17.70), num.er of grains per row (34.31), num.er of grains per cob (678.58), and cob weight (187.50 g) were observed in deep tillage at 200 kg•ha-1 nitrogen application. 1000-grain weight (275.52 g), biological yield (15.66 t•ha-1), grain yield (6.16 t•ha-1) and dried stalk yield (9.91 t•ha-1) were observed m.xim.m.in deep tillage at 200 kg•ha-1 nitrogen application. Harvest index significantly affected by tillage regim.s and m.xim.m.harvest index (39.58%) were recorded in deep tillage which was statistically at par with conventional tillage (38.83%). It was concluded that higher grain yield of m.ize can be obtained by deep tillage with the application of 200 kg•ha-1 nitrogen application under the prevailing conditions of Faisalabad.

Introduction: Bangladesh has experienced rem.rkable growth in Rm. over the past 25 years. With the knitwear industry providing m.re than 4 m.llion direct jobs, providing better occupational health and safety of workers rem.ins a challenge. Aim.of the study: The aim.of the study was to analyze the disease burden of a Rm. factory, and to highlight occupational health risks. m.thods: A cross-sectional study design was em.loyed for this analysis. A 17-m.nth data entry (January 2020 - m.y 2021) was gathered from.the factory in-house clinic. The socio-dem.graphic and clinical diagnosis entries of 8421 entries were analyzed. Result: The population of the factory workers is 5370, where 40% (2148) are fem.le workers and 60% (3222) are m.le workers. The m.an age of respondents is 30 years, with a SD of ±7 years. Am.ng the chief com.laints, the m.st com.on was vom.ting (14%;2262) fever (14%;2247), runny nose (11%;1842), cough (9%;1465), and loose m.tion (8%;1364). In the diagnosis categories, gastrointestinal diseases were m.re predom.nantly diagnosed (35%;2978), followed by viral fever (21%;1772), neurological diseases (16.5%;1389) and m.sculoskeletal disorders (9%;768). The average cost of m.dicine for each respondent is BDT 36. The factory covered costs of all m.dication for 99% (8380) of respondents. Only 0.5% (37) was referred to a tertiary hospital for further evaluation. Conclusion: Garm.nts workers suffer m.stly from.long-term.occupational health hazards. Factory owners and policy m.kers can contribute in various ways to im.roving prim.ry healthcare options for workers.

For solving higher dim.nsional diffusion equations with an inhom.geneous diffusion coefficient,m.nte Carlo（m.） techniques are considered to be m.re effective than other algorithm., such as finite elem.nt m.thod or finite difference m.thod. The inhom.geneity of diffusion coefficient strongly lim.ts the use of different num.rical techniques. For better convergence, m.thods with higher orders have been kept forward to allow m. codes with large step size. The m.in focus of this work is to look for operators that can produce converging results for large step sizes. As a first step, our com.arative analysis has been applied to a general stochastic ***, our form.lization is applied to the problem.of pitch angle scattering resulting from.Coulom. collisions of charge particles in the toroidal devices.
