Soil color

The present study evaluated the effect of different colored plastic mulching viz. olive polythene film (OPF), silver polythene film (SPF), white polythene film (WPF), black polythene film (BPF) and blue polythene film (BLPF) on soil properties, growth, physiology, biochemical and mineral nutrient composition in onion bulbs. Soil properties at 0–10 cm depth are variably affected by colored polythene film mulches.

Fungi have diverse biotechnological applications in, among others, agriculture, bioenergy generation, or remediation of polluted soil and water. In this context, culture media based on color change in response to degradation of dyes are particularly relevant; but measuring dye decolorisation of fungal strains mainly relies on a visual and semiquantitative classification of color intensity changes.

In nature, there exist a wide variety of microbes that can be of any economical importance to humans. A specialized group of microorganisms includes pigmented yeasts. They are yeasts that develop colored pigment as their secondary metabolites. In this study, pigmented yeasts were isolated from different sample (soil, leaves, fruits, coconut, and air) on Sabouraud’s agar. Four strains were selected that showed pigmentation. Various morphological and biochemical tests were performed for identification of the strains.

The main reason to study this area is to evaluate soil health status at various depth by analysing the physical properties of soil. So that to make recommendation towards achieving sustainable utilization and agricultural production. The most important reason for choosing this area is that as of very less research paper in this region most of the farmers are not aware about theresoil condition. Thus, still they are dependent on conventional method without implementing advance technology.

Collar rot or damping off disease occurs on one to four month old tender coffee (Coffea Arabica) seedlings in the nursery. Sometimes, the collar rot pathogen infects coffee seeds sown on the seed beds and prevents the germination. However, the pathogen fails to establish in coffee seedlings when the stem at collar region turns brown in color and becomes harder. It is a soil inhibiting fungus with a wide host range including coffee.

A red pigment producing bacteria was isolated from soil sample which was identified by 16S r RNA sequencing as Serratia rubidaea JCM 1204T. The red pigment produced was tested for prodigiosin by presumptive color test, adsorption spectra, and its quantification was carried out on King’s B medium. For presumptive color test, the extracted pigment solution was divided into two portions. One part was acidified with a drop of concentrated HCl and the other part was alkalinized with a drop of concentrated ammonia solution.

A tractor operated plastic mulch laying equipment was developed in the department of Farm Machinery and Power Engineering, CAE, UAS Raichur. It was developed to mechanize the conventional plastic mulching operation. A plastic mulch roller was mounted on the main frame of equipment. A 35 hp tractor was used as a power unit for both plastic mulching and drip laying operations.

Pseudomonas fluorescens is an aerobic, gram-negative, ubiquitous bacterium present in agricultural soils that is well adapted to grow in the rhizospheric as well as phyllospheric zone. An experiment was conducted at Shree Agrasen Kanya P.G. College, Varanasi, U.P. India aimed to determine the morphological features of P. fluorescens as well as to carry out the process and method of its commercial production of powder formulation of the bio-control agent P. fluorescens 1 % W.P for its effective use at field.

The primary objective of this study is to explore fungal pigments as a source for dyeing colorants. Owing to the conflicting reports on the safety of textile and leathers during dyeing and due to the indiscriminate use of non-permitted colors, there is an urgent need to identify natural pigment sources as safe textile colorant. This study critically examines the potentials of fungi as sources production of biocolorant. Along with an established pigment producing fungus, Monascus, newer fungi have been explored and reported.

Blue banded bees are solitary bees which are characterized by their glittering blue color bands on their abdomen. They construct their nests and brood cells for their young ones in soils. The developmental biology of blue banded bees is maximum sixty days and varied according to climatic conditions. They are polylectic and wild pollinators playing major role in crop pollination. Research on blue banded bees is very limited and less studies. In this review we will focus on diversity, bio-ecology and behavior of blue banded bees.

A total of 50 PPFM’s were isolated from rhizosphere soil and phyllosphere of direct seeded rice regions of Hyderabad-Karnataka. Samples of leaves and rhizosphere soils were collected from direct seeded rice grown in different location (Raichur district, Bellary district, Koppal district and Yadgir district). Thereafter, all the classical recommended methods used for identification of all the obtained isolates were carried out including, morphological, microscopical as well as biochemical characteristics. The results revealed that all the isolates were gram negative, rod shaped, motile.

Pigments play a very significant role in all aspects of life. They find application in a variety of industries like food industries, textile industries, pharmaceutical industries etc. One of the major reasons behind the increasing market interest for microbial pigments is their eco-friendly nature and their compatibility with the living. Besides this, they also reported to impart many additional benefits due to their anti-bacterial, anti-oxidant, antimalarial and anti-biotic properties etc.

Distillery is one of the most highly polluting and growth oriented industries in India with reference to the extent of water pollution and the quantity of wastewater generated. Apart from distilleries, fermentation industries, sugar mills, pharmaceutical companies and other molasses based industries are also responsible for contamination and generation of waste water. The distillery waste water contains dark brown colored recalcitrant compounds collectively termed as melanoidin polymers. These polymers cause oxygen depletion and increase BOD.

Children were among the most enthusiastic early viewers of television. Programs targeted specifically at children were intro- duced early, with Howdy Doody making its debut in 1947 and a number of popular series such as Kukla, Fran, and Ollie; Jam- boree Room;and Children’sMatinee on the air by 1948 (Television Magazine 1948). Children’s programs accounted for more time on network television than any other category in 1950 (Roslow 1952), and by 1951 advertiserswere spending $400,000 perweek to reach the children’s market (Television Magazine 1951). ...

By early summer he was free enough to write. “I feel that now I can try to conjure something up for Princeton.” Disks and No Disks was the title of what evolved. Barr suggested one or more of the disks be painted orange to honor the colors of Old Nassau. A wary Calder replied, “After my initial reluctance to paint anything orange, I think all 3 disks might be good.” A few weeks later he amended this, “I suggest that you paint the smallest ‘Orange.’” In anticipation of the artist’s visit to Princeton in November 1971, all four solid disks had been painted orange.
