Correlation and Path Analysis in Cotton (Gossypium Hirsutum L.)
By:
Sharad V Pawar
The phenotypic correlation coefficient and path coefficient analysis in F2
Generation of cross CNHPT- 1 x RHC-1488 of cotton (Gossypium hirsutum L.)showed a
Significant positive association of seed cotton yield per plant with plant height, number of bolls per plant, average boll weight and ginning pert centage . path analysis indicated that number of bolls per plant and average boll weight had direct effect on seed cotton yield. Thus maximum emphasis for selection of better genotypes should be given to number bolls per plant and average boll weight and also to number of sympodia per plant and plant height.

Quality Testing of the Compost
By:
surender singh
Recently due to surge in area of organic farming, the demand for compost has increased significantly. Before 2006, due to lack of quality control measures, the market was flooded with poor quality compost and other organic manure. Finally in 2006, government has notified amendment in Fertilizer Control Order to include city compost and vermicompost in order to improve the quality of these inputs.

Effect of Deleterious Rhizosphere Microorganisms in Presence of HCN
By:
Shruti agrawal
The saprophytic microflora of the rhizosphere includes both deleterious and beneficial elements have the potential to influence the plant growth and yield, significantly. Their deleterious activities include alterations of the supply of water, ions and plant growth substances by changing root functions or limiting their growth. The beneficial bacteria affect plant growth positively by promoting the availability and uptake of mineral nutrients, provision of plant-growth substances as well as suppression of deleterious rhizosphere microorganisms. Deleterious rhizosphere microorganisms (DRMO) are the minor pathogenic rhizosphere microorganisms that affect plants by their metabolites without parasitizing plant tissue. These include deleterious rhizobacteria and rhizofungi.

Azolla: A Green Manure
By:
Shivika Bhatnagar
Azolla is a free floating freshwater fern. The plant body consists of crowded mass-like leaves on a branched fragile stem and submerged roots.The leaves are arranged in two alternate rows. The leaf is triangular or polygonal in shape. It has an upper lobe called aerial lobe and a lower lobe called submerged lobe. The ventral surface of the aerial lobe bears mucilage cavities harbouring the blue green algae, Anabaena azollae.

Biosyntheis of Cytokinin
By:
Shivika Bhatnagar
Cytokinins are degradation products of DNA. They are made up of adenine nucleus and a furfural ring. This basic structure is known as 6- furfuryl aminopurine. Cytokinins stimulate cell division and enlargement of cells. The deficiency of cytokinins results in stunted growth in plants.

Fermentation Process in Popular Oriental Foods
By:
Shivika Bhatnagar
Article explains the process of fermentation in common oriental foods like Tempeh, Soy sauce, Natto and Miso. Mycoproteins, marketed in some foreign countries under the name Quorn, is essentially the mycelium of Fusarium graminerarum grown in continuous culture in a medium containing glucose, ammonium salts and a few growth factors. It is essential to reduce the level of RNA which is about 10% on mycelial dry weight to below the levels likely to lead to kidney- stone formation or gout. This can be achieved by mild heating prior to filtration which activates the RNAses and leads to RNA reduction. Such products contains 44% of protein and is high in 'fiber' contents.
