Growth and Yield of Hybrid Maize as Influenced by Fertilizer Management

An experiment was carried out at the Agronomy Field Laboratory, Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Bangladesh during the rabi season (December to May), 2012-13 to study the effect of different organic and inorganic fertilizers on growth and development of hybrid maize (Denali). The experiment was laid out in Randomized Complete block Design with three replications with 30 plots. Ten fertilizer treatments (T1= Compost, T2= Cow dung, T3= Poultry manure, T4= Recommended fertilizer dose, T5= Compost + Half recommended fertilizer dose, T6= Compost + Full recommended fertilizer dose, T7= Cow dung + Half recommended fertilizer dose, T8= Cow dung + Full recommended fertilizer dose, T9= Poultry manure + Half recommended fertilizer dose, T10= Poultry manure + Full recommended fertilizer dose. The recommended fertilizer dose was 500 Kg ha-1 urea + 250 Kg ha-1 TSP + 200 Kg ha-1 MP + 15 Kg ha-1 ZnSO4 + 6 Kg ha-1 Boric Acid. And the rate of Compost, Cow dung and Poultry manure was 10t/ha. The effect of different manure and fertilizer doses on the yield and yield attributes were significant. The plant height, number of leaves per plant, weight of stem per plant, weight of leaves per plant, length of cob, grain weight per cob, diameter of cob, no. of grains per row, no. of total grains per cob, 1000-grain weight, yield plant-1, yield ha-1 were significantly affected by different manures and fertilizer uses with different doses. The treatments T1, T2, T3, T4, T5, T6, T7, T8, T9 and T10 gave grain yield 10.16, 9.09, 8.49, 14.34, 13.35, 18.12, 11.99, 17.09, 11.40 and 15.98 t ha-1, respectively. The T6 Treatment gave higher grain yield (18.12) t ha-1 and the T3 treatment performed lowest grain yield (8.49 t ha-1). The application of compost and full dose fertilizer is higher yielding. Balance nutrition with enough organic matter enrichment of the soil is the cause of this result

Esophageal leiomyomatosis – an unusual cause of pseudoachalasia

Esophageal leiomyomatosis is a rare hamartomatous disorder with varied presentation. In the literature, it is described mostly in children, and is associated with Alport’s syndrome. A case of leiomyomatosis that presented as achalasia not associated with Alport’s syndrome is described in a 35-year-old woman with a 16-year history of dysphagia. Barium swallow showed a smooth narrowing at the lower end of the esophagus with a longer than usual stricture length. Endoscopy showed a dilated esophagus with a submucosal nodule in the region of the cardia. A computed tomography scan revealed circumferential thickening of the esophagus involving the gastroesophageal junction, with fat planes maintained with the adjacent structure. Endoscopic ultrasound demonstrated a lesion arising from the muscularis propria. The manometry findings were suggestive of achalasia. She underwent transhiatal esophagectomy with gastric pull-up

An in silico structural, functional and phylogenetic analysis with three dimensional protein modeling of alkaline phosphatase enzyme of Pseudomonas aeruginosa

Phosphorus is a primary macronutrient required for normal plant health, metabolism and survival. It is present in soil in compound insoluble form for which plant cannot uptake it directly from the soil. Some phosphate solubilizing bacteria possess some important enzymes for phosphate solubilization as well as mineralization. Alkaline (or basic) phosphatase (EC 3.1.3.1) is a type of zinc containing dimeric hydrolase enzyme responsible for removing the phosphate groups from various kinds of molecules including nucleotides, proteins, and alkaloids. Unlike acid phosphatases alkaline phosphatases are most effective in an alkaline environment. Alkaline phosphatases (ALPs) are of immense importance in various agricultural industries including dairy industries for testing successful pasteurization process. In this present study, Pseudomonas aeruginosa phosphatase was selected for a detailed computational investigation to exploit its physicochemical characteristics, structural properties including 3D model, model quality analysis, phylogenetic assessment and functional analysis using a number of available standard bioinformatics tools. The protein having average molecular weight about 51 kDa, was found thermostable and alkaline in nature belonging to metalloenzyme superfamily. Specifically, the thermostable behavior of the protein is suitable for the dairy industry. Moreover, this theoretical overview will help researchers to get an idea about the predicted protein structure and it may also help to design genetically engineered phosphate solubilizing bacteria by designing specific primers

Yield and Yield Components of Maize as Affected by Planting Density

An experiment was carried out to investigate the effect of planting density on growth, development, yield and yield components contributing characteristics of maize during the period of November, 2012 to March 2013 in the Research Field and Laboratory of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh. The experimental area belongs to Old Himalayan Piedmont Plain (AEZ-1) of Bangladesh having sandy loam soil with pH 6.1. The experimental treatments were five plant spacing (S1=75 cm X 25 cm, S2=75 cm X 20 cm, S3=60 cm X 25 cm, S4=65 cm X 20 cm and S5=50 cm X 25 cm) corresponding to 35,000, 50,000, 60,000, 80,000, 95,000 plants ha-1 respectively with one maize variety. The experiment was laid out in a single factor Randomized Complete Block Design (RCBD) with four replications. The experiment plots were divided into four blocks each representing a replication. Growth parameters, some phenological parameters such and some yield and yield attributes increased with decreased in plant the plant population. The highest grain yield of 5.65 t/ ha was produced at (S5) high planting density (95,000 plants ha-1) and the lowest grain yield of 4.21 t/ha was produced at (S1) lowest planting density (35,000 plants ha-1). &nbsp
